NOTE 1: EVALUATION OF BIDS - ADDITIVE ITEMS 252.236-7007 (DEC 1991):
-------------------------------------------------------------
(a) The low offeror and the items to be awarded shall be determined as
follows--
(1) Prior to the opening of bids, the Government will determine the amount
of funds available for the project.
(2) The low offeror shall be the Offeror that--
(i) Is otherwise eligible for award; and
(ii) Offers the lowest aggregate amount for the TOTAL ESTIMATED BASE BID,
plus (in the order stated in the list of priorities in the bid schedule) those
additive or deductive items that provide the most features within the funds
determined available.
(3) The Contracting Officer shall evaluate all bids on the basis of the
same additive or deductive items.
(i) If adding another item from the bid schedule list of priorities would
make the award exceed the available funds for all offerors, the Contracting
Officer will skip that item and go to the next item from the bid schedule of
priorities; and
(ii) Add that next item if an award may be made that includes that item and
is within the available funds.
(b) The Contracting Officer will use the list of priorities in the bid
schedule only to determine the low offeror. After determining the low offeror,
an award may be made on any combination of items if--
(1) It is in the best interest of the Government;
(2) Funds are available at the time of award; and
(3) The low offeror's price for the combination to be awarded is less than
the price offered by any other responsive, responsible offeror.
(c) Example:
The amount available is $100,000. Offeror A's base bid and four additives
(in the order stated in the list of priorities in the bid Schedule)
00010-6
are $85,000, $10,000, $8,000, $6,000, and $4,000. Offeror B's base bid and four
additives are $80,000, $16,000, $9,000, $7,000, and $4,000. Offeror A is the low
offeror. The aggregate amount of offeror A's bid for purposes of award would be
$99,000, which includes a base bid plus the first and fourth additives. The
second and third additives were skipped because each of them would cause the
aggregate bid to exceed $100.000.
(End of provision)
NOTE 2: CONTRACT AWARD: The work will be awarded to one bidder. Bidders shall
--------------
bid all items set forth on the Bidding Schedule.
NOTE 3: FUNDING LIMITATIONS - UNBALANCED BIDS: Due to funding limitations, it
-------------------------------------
is mandatory that bids not be unbalanced. If, in the opinion of the Government,
the low bidder has unbalanced his bid, the Government will require the bidder to
furnish a breakdown of his bid in such detail as will enable the Government to
take appropriate action.
NOTE 4: SCOPE OF CONTRACT: The work represented by the base bid will be the
-----------------
minimum amount of work awarded within the funds available.

information. The Government shall not be responsible for any interpretation of
or conclusion drawn from the data or information by the Contractor.
a. Site Conditions: The indications of physical conditions on the
drawings and in the specifications are the result of site
investigations and surveys. The conditions represented prevailed at the
time the investigations and surveys were made. A pre-dredge survey of
Boston Harbor will be performed by the Government prior to the start of
Contractor dredging operations at the site. Before commencing work at the
site, the Contractor shall verify the conditions indicated on the drawings
and in the specifications and perform all other surveys as needed or as
required in the contract documents.
b. Weather Conditions: The monthly normal mean temperature and the

1.4.4 Method of Surveying
1.4.4.1 Soundings
To assure that the method of surveying is acceptable, the Contractor shall
submit, as part of the Quality Control Plan a detailed proposal setting out the
proposed method of surveying. Soundings shall be referred to Mean Lower Low
Water (MLLW) and shall be performed with a depthsounder having a vertical
accuracy of 0.1 foot. In general, sounding lines shall be perpendicular to the
channel limits and shall extend a minimum of 3 times the channel depth outsidd
of the limits except where limited by the surrounding topography or lack of
sufficient depth for the survey boat. For the first disposal cell, the range of
the Contractor survey shall be 1 barge length (up to 300 feet) beyond the
perimeter of the cells. For subsequent cells, the range of the contractor survey
will be at least 50 feet beyond the perimeter of the cell. The interval between
sounding lines shall be a maximum of 50 feet. Control points used for the
surveys shall be occupied and proven by checking reference angles in the field.
Depth measuring equipment must use a recording depthsounder with a transducer
beam angle not exceeding 8 degrees. Horizontal positioning systems shall be a
Differential Global Positioning System (DGPS). Whatever system is used shall be
capable of locations accurate to 1 meter or better of the true position. At the
start of each day's soundings, following any lengthy breaks and at the end of
the day's soundings a bar check shall be taken within two feet of the project
depth and recorded on the depthsounder roll. Events marks shall be marked and
titled on depthsounder rolls. Sounding lines shall be numbered on the
depthsounder rolls and plots. Events marks shall correlate horizontal position
with depth and shall be marked and numbered on depthsounder rolls. They shall be
taken at 30 second intervals. The Contractor will be required to submit to the
Contracting Officer sufficient field data, including depthsounder rolls in a
usable format, corrected for tide, and corresponding boat plots and track
sheets, so that the Contractor's submitted survey plot may be reproduced by the
Government by referring only to this field data. After completion of the
Contractor's survey, the results will be plotted and reviewed by the Contractor
to insure that all work was completed in accordance with contract requirements
and submitted to the Contracting Officer on a floppy disk in ASCII format. A re-
survey of the area after correction of deficiencies will be required to assure
that correction has been achieved. Upon completion of the project sufficient
surveys will have been performed and plots submitted to assured that the proper
depth has been achieved throughout the entire project. Submission of all
Contractor quality control survey data, including plots, is required prior to
performance of final examination and acceptance surveys by the Government. The
results of quality control survey should be utilized by the Contractor to ensure
that work was performed in accordance with contract requirements. Final

SECTION 01050 Page 4
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
made at the expense of the Government by soundings or full coverage
electronic sweeping operations, or both, as determined by the Contracting
Officer. Should any shoals or other lack of contract depth be disclosed by
this examination, the Contractor shall remove these shoals by dredging,
at the contract rate, or by otherwise removing the shoals, as directed by
the Contracting Officer. The Contractor or his authorized representative
will be notified if and when soundings and/or sweeps are to be made. One
individual will be allowed to accompany the survey party during the final
examination survey(s). When the area is found to be satisfactorily cleared,
it will be accepted finally. Should more than one final examination survey
of an area be required, the cost of all additional surveys of that area
will be deducted from amounts due or to become due the Contractor. These
survey costs will be based upon a rate of $2,400.00 per day for each day in
which the Contracting Officer survey plant is engaged in sounding or
sweeping operations, and/or is en route to or from the site, or held at or
near the site for such operations.
1.6.2 Final Acceptance

CONDITIONS RECOMMENDED BY THE NATIONAL MARINE FISHERIES SERVICE FOR PROJECTS
FUNDED OR UNDERTAKEN BY THE CORPS OF ENGINEERS THAT INCLUDE DISPOSAL OF DREDGED
MATERIAL AT THE MASSACHUSETTS BAY DISPOSAL SITE
March 27, 1997
(1) From February 1 through May 30 of any year, disposal vessels including tugs,
barges, and scows transiting between the dredge site and the Massachusetts Bay
Disposal Site shall operate at speeds not to exceed 5 knots after sunset, before
sunrise, or in daylight conditions where visibility is less than one nautical
mile. Disposal shall not proceed if these requirements cannot be met due to
weather or sea conditions. In that regard, the vessel captain and/or contractor
should be aware of predicted conditions before departing for the disposal site.
The intent of this condition is to reduce the potential for vessel collisions
with threatened and endangered species, including right whales.
(2) From February 1 through May 30 of any year, an approved marine observer
(i.e., meeting the attached National Marine Fisheries Service (NMFS) criteria on
observer qualifications, including the specified skill sets for sea turtles and
whales) must be present aboard disposal vessel transiting between the dredge
site and the Massachusetts Bay Disposal Site during daylight hours. When
threatened or endangered species are observed to be present, the vessel captain
shall, except when precluded by safety considerations, follow the advice of the
marine mammal observer to avoid harassment of or direct impact to individual
animals. The observer shall fully complete a separate Corps of Engineers marine
mammal observation report for every sighting and shall ensure that this report
is received by the Corps New England District, Environmental Resources Section
(fax number (978) 318-8560) and The Regulatory Compliance Branch (fax number
(978) 318-8303) within one week of the trip date. The observer shall maintain
contact with the NMFS (Habitat and Protected Resource Division, phone number
(508) 281-9328) and other recognized experts to provide and receive information
regarding the presence and distribution of threatened and endangered species in
Massachusetts Bay. All right whale sightings (including location) shall be
reported to Ms. Pat Genior at NMFS Woods Hole (telephone number (508) 495-2264)
at the end of the day. The intent of this condition is to reduce the potential
for vessel collisions with threatened and endangered species, including right
whales, and to minimize potential impacts of dredged material disposal on
threatened and endangered species.
Marine mammal observers shall use the following guidelines to minimize conflicts
with threatened or endangered species:
(a) A marine mammal observer shall be posted on lookout at all times during
daylight hours when disposal vessels have left the harbor and are underway or at
the disposal site.
(b) Disposal vessels shall not approach threatened or endangered species closer
that 100 feet (see additional condition below for approaching right whales).
(c) Disposal vessels shall adhere to the attached NMFS regulations for
approaching right whales, 50 CFR Part 222.32, which restrict approaches within
500 yards of a right whale and specify avoidance measures for vessels that
encounter right whales.
(d) If threatened or endangered species are sighted within 500 feet from the
disposal point, dredged material shall not be released. In this case, the vessel
captain may elect to wait until the animals move away from the disposal point
prior to disposal, or, subject to the judgement of the observer, may dispose at
an authorized alternative disposal location under the same restrictions noted
herein for disposal at the primary disposal
SECTION 01130 Page 9
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
location.
(e) If threatened or endangered species are sighted between 500 feet and 1500
feet from the disposal point, the observer shall note the animal's behavior,
relative position, and direction and speed of movement to determine if release
of dredged material is likely to harass or endanger the animals. For example,
whales actively feeding at or near the disposal point are more likely that
resting whales to interact with released sediments. If the observer judges
that disposal is likely to harass or endanger the animals, the observer shall
inform the vessel captain and disposal shall be delayed until the animals
change their behavior or move away such that the observer judges that no
danger to the animals will result from disposal.
OBSERVER CREDENTIALS
Certain credentials and experience might indicate an observer has the skills
listed below. Ideally, the applicant will have an educational background in
marine biology, general experience aboard dredges, and hands on field

SECTION 01135 Page 4
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
PART 3 EXECUTION
3.1 DREDGING REQUIREMENTS
3.1.1 Environmental Clamshell Bucket
Dredging of all soft surface sediments in the Mystic and Chelsea Rivers, the
Inner Confluence and the Reserved Channel Federal channels and in the
associated non-federal project berth areas shall be done using a closed
environmental clamshell bucket, such as the CableArm bucket, or approved
equal. The dredge bucket shall be designed to completely enclose the dredged
sediment and water captured. The bucket shall not have teeth. (This is to
prevent the bucket from digging into the hard parent material.) The bucket
shall be equipped with escape valves which shut when the bucket is withdrawn
from the water column. The environmental dredge bucket shall have demonstrated
the capability of meeting the following water quality performance standards;
a. Suspended solids shall not exceed 25 mg/1 over background at 25 m (75
ft) from operation when ambient levels are lower than 100 mg/1.
b. Turbidity shall not exceed ambient levels by more than 30% at 25 m (75
ft) from operation.
3.1.2 Environmental Bucket Control
The Contractor shall demonstrate that for Maintenance dredging the dredge
operator has sufficient control over bucket depth in the water and bucket
closure so that sediment re-suspension from bucket contact with the bottom and
due to bucket over-filling can be minimized.
3.1.3 Debris Management Plan
The Contractor shall follow an approved Debris Management Plan. See SECTION
01130 ENVIRONMENTAL PROTECTION for plan submittal requirements. Where pilings
or other debris is found to interfere with environmental bucket closure or
equipment operation, a conventional clamshell bucket may be used to extract
the pilings/debris. Abandoned piles shall be cut or broken off rather than
extracted. Sediment removal during such activity shall be minimized to the
greatest extent practicable. Berths adjacent to pile structures include but
are not limited to Conley berths 11-17, Moran Terminal, Mystic Pier 1 and
Berths 49 and 50, and North Jetty. Historic pilings or debris may exist at
other project sites.
3.1.3.1 Release of Oily Material
All oily material released during dredging or other project activity shall be
promptly collected and disposed at a licensed facility.
3.1.3.2 Discharge of Sediment
All barges used shall be in good operating condition and shall contain the
sediment and water placed in it so that minimal discharge of sediment or water
occurs until the barge has been transported to the authorized disposal
location(s). Deck barges shall not be used to contain channel or berth dredged
sediments unless the barge has been modified to provide for complete
containment of the sediments.
3.1.3.3 Communication During Discharge
The Contractor shall provide the sampling and monitoring crew with a signal
acceptable to both parties indicating when the dumping of sediment from the
barge begins. This is essential since monitoring events are timed relative to
the dumping event.

BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
3.1.4 Equivalent Alternative Dredging Technology
Alternatives to the Environmental Clamshell Bucket technology for the removal
of soft material will not be considered under this contract. However, the
Contractor may submit a "Value Engineering Change Proposal" under the terms
and conditions of contract clause "VALUE ENGINEERING -- CONSTRUCTION (MAR
1998)--ALTERNATE I (APR 1984), following contract award, See Section 00700,
Contract Clauses.
3.2 WATER COLUMN MONITORING - BASELINE
Baseline water column data was collected under a previous contract. Data
collected was for the recommended analyses including: dissolved metals
(arsenic, cadmium, copper, chromium, lead, mercury, nickel, zinc,) and PCBs,
as well as TSS and dissolved oxygen (D.0). The data was collected from a plume
generated by a ship in the Inner Confluence. Relevant results were included in
a written report for "Sample Event #3" prepared by the U.S. Army Corps of
Engineers Environmental Laboratory, Hubbardston, MA. The report is available
for review as specified in paragraph "Existing Reports and Historical Data" of
Section 02482 DREDGING.
3.3 WATER COLUMN MONITORING - DREDGING OF DISPOSAL CELLS
Spatial and temporal distribution of the sediment plume shall be documented
(See paragraph WATER COLUMN MONITORING - DISPOSAL OPERATIONS below) under
conditions of slack tide and maximum tidal current within the first month of
dredging surface maintenance material from the cell(s). Dredging shall have
been on-going for at least two hours and dredge cycle time shall be recorded
and reported for this period. Documentation for each tidal condition shall
include:
a. A plan view figure (similar to Figure 3.5, Appendix F, FEIR/S attached
at the end of this section) depicting contours of turbidity or light
transmittance values over an area encompassing the dredging activity and
extending a minimum of 300 feet upcurrent and 1000 feet downcurrent and 200
feet laterally from the dredging activity; depths depicted shall be mid
water column and within three feet of the bottom;
b. A figure in cross section depicting contours of turbidity or light
transmittance along a line 300 feet downcurrent of the dredging activity
and perpendicular to the general current direction extending 200 feet
laterally from the dredging activity; full depth of the water column shall
be represented.
c. The documentation shall be reported as specified above in paragraph
"Monitoring Report for Each Monitoring Event."
3.4 WATER COLUMN MONITORING - DISPOSAL OPERATIONS
3.4.1 Plume Location Equipment
Plume location equipment, for example a transmissometer, shall be used to
ensure that all downcurrent samples are located within the maximum density
(lateral dimension only) of a sediment plume. The instrumentation used to
locate the plume shall be capable of providing real-time display and data
capture of light transmittance or turbidity as a depth profile. Measurements
shall be of sufficient spatial and temporal coverage such that the following
requirements can be met:
a. A plan view figure (similar to figure 3.5, Appendix F, FEIR/S)attached
at the end of this section) can be generated depicting contours of
turbidity or light transmittance values over an area extending a minimum of
300 feet upcurrent and 1000 feet downcurrent and 200 feet laterally from
the project activity at a specified depth;
Page 6
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
b. A figure in cross-section can be generated depicting contours of
turbidity or light transmittance along a line 300 feet downcurrent of
the project activity and perpendicular to the general current
direction extending 200 feet laterally from the project activity. The
full depth of the water column shall be represented.
3.4.2 Special Monitoring for Mystic River Federal Channel
Water column sampling and analysis for total PCBs, dissolved copper,
cadmium, lead, total mercury and TSS (total suspended solids) shall be
conducted when soft surface sediments from Mystic River Federal channel are
disposed in-channel disposal cells, as follows:
3.4.2.1 Construction Events and Frequency of Sampling
This requirement shall apply to disposal activity at the first cell(s)
filled with Mystic River soft surface sediments, and to the first three
disposal events in each tributary in which more than 3000 cy of Mystic
River sediments are disposed per tidal cycle.
a. Monitoring at the first cell shall occur during two days in the
first week that disposal occurs in the cell. Monitoring shall also
occur during three days that disposal occurs once the cell is at least
50 percent filled to its design capacity. A record of the number of
scow loads and the volume of each shall be included with the
monitoring reports required by this section.
b. In order to allow the Contractor to safely monitor disposal events,
this requirement shall apply to one disposal event (or series of
events if more than one disposal event occurs in a given tidal cycle)
per day. When disposal events occur during both high tide periods in a
day, the Contractor shall monitor the event associated with the most
favorable weather and light conditions.
3.4.2.2 Depth of Sample
All samples (including reference samples) shall be obtained from within 3
feet of the harbor bottom outside the cell and from the mid-water column.
These samples shall be combined. Alternatively, a depth integrated
composite sample may be obtained from the same depths.
3.4.2.3 Location of Plume Samples
Plume samples shall be obtained 300 feet downcurrent from the cell.
Distances shall be measured from the closest boundary of the cell.
NOTE: For all water column samples required by this specification,
----
downcurrent and upcurrent shall be determined relative to the bottom
current direction, as indicated for the specific tide time on NOAA
Tidal Charts for Boston Harbor.
3.4.2.4 Location of Reference Samples
Reference samples shall be obtained to represent local background water
conditions outside the affect of sediment disposal events. Acceptable
locations for reference samples include:
a. A point 1000 feet upcurrent (with respect to bottom current
direction) of an active disposal cell, and
b. A point 300 ft downcurrent from the disposal cell prior to
disposal, provided there has been no dredging at the cell for 12 hours
and that no disposal into the cell (or into an upcurrent adjacent
cell) occurred on the same tidal cycle. Other locations may be
approved by the Contracting Officer in coordination with the
Massachusetts
SECTION 01135 Page 7
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
Department of Environmental Protection upon request.
3.4.2.5 Time of Sampling:
a. At 0.5 and 1.0 Hours Post Disposal:
Plume samples shall be obtained 0.5 hours and 1.0 hours after the disposal
event. Location of samples must be 300 feet downcurrent as specified; however,
time maybe modified slightly in order to meet the requirement to obtain the
sample from the plume. If multiple dumps will occur on any one tidal cycle,
timing for the plume sample shall be measured from the last dump. These
samples shall be analyzed separately and will be used for determining whether
acute criteria are met. One reference sample shall be obtained prior to
disposal and analyzed for comparison to the 0.5 and 1.0 hour plume samples.
b. At 4 to 6 Hours Post Disposal:
Two or more additional plume samples shall be collected one hour apart during
the period four to six hours after disposal, and a single composite sample
prepared for analysis. This sample represents the average disposal plume for
the period up to twelve hours after disposal. Tidal conditions are expected to
be approximately slack low. Two upcurrent reference samples shall be obtained
during the 4 to 6 hour post-disposal period and combined for one analysis.
These samples will be used to determine whether chronic criteria are met.
3.4.2.6 Reporting 36 Hour Data
The resulting monitoring data shall be reported as specified above in
paragraph "ADMINISTRATIVE REPORTING REQUIREMENTS" within 36 hours from the
time the analytical laboratory receives the samples. If the 36 hour deadline
occurs after 5 pm or during the weekend, the data may be reported by 9 AM the
following business day. Failure to meet this requirement may result in a Stop
Work Order from the Contracting Officer. The Contractor shall report the data
on a form similar in detail to that attached at the end of this section.
3.4.2.7 Plume Cross Sectional Figure
A cross sectional figure of the plume at 300 ft down current from the cell
shall be generated with the plume location equipment as specified in paragraph
"Plume Location Equipment", above, immediately following the collection of the
1.0 hour plume sample for each monitoring event.
3.4.2.8 Dissolved Oxygen Measurements
A series of at least three dissolved oxygen measurements shall be made with
real time instrumentation at all locations, depts and times specified above.
3.4.3 Special Monitoring for the Chelsea River Federal Channel
Water column sampling and analysis as described above shall also be conducted
during five (5) days of disposal occurring in cell(s) in the Chelsea River.
3.4.4 Monitoring for TSS and Turbidity
Monitoring for TSS and turbidity is required during the first week of in-
channel disposal into a cell. Sampling shall occur during three days.
Requirements for sample locations, timing, depth, reporting and cross-section
figure are as described above in paragraph "Special Monitoring for Mystic
River Federal Channel."
SECTION 01135 Page 8
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
3.4.5 Monitoring of Material from Berths
Monitoring as specified above shall also be conducted when sediment from
Prolerized, Distrigas, and Mystic Terminal Berths 2, 49 and 50 comprises
more than 50% of the materials in a large load disposed in harbor bottom
cells. Samples shall be analyzed for dissolved chromium, arsenic, nickel,
zinc, and total mercury as well as dissolved copper, cadmium, lead, total
PCBs, TSS and D.O.
3.4.5.1 Bioassays of Material from Mystic River and Berths
Bioassays shall be conducted to monitor (1) disposal of Mystic River
sediments, and (2) disposal of sediment from Prolerized, Distrigas, and
Mystic Terminal Berths 2, 49 and 50. Water Samples shall be obtained on one
day during the first two days of Monitoring for normal disposal operations
as required in paragraph "Special Monitoring for Mystic River Federal
Channel" and "Monitoring of Material from Berths" above. The tests shall be
run using a composite of two (or more) water samples collected one hour
apart at a location 300 ft downcurrent from the cell during the period four
to six hours following disposal. Water samples from the appropriate
reference sites shall be tested likewise.
3.4.5.2 Bioassay Protocols
Two bioassays shall be conducted on each required sample as follows. The
sea urchin fertilization test shall be conducted according to EPA protocols
for chronic end point(s). Likewise the seven-day (Mysidopsis bahia)
----------------
(shimp) test shall be conducted according to EPA protocols for chronic end
points. The purpose of this requirement is to assess the biological effects
of a combination of pollutants which may be present; water quality criteria
alone do not address this factor. In addition, where chemical criteria are
exceeded and biological tests indicate no adverse effect, the Massachusetts
Department of Environmental Protection will consider the biological test
results as more significant in determining whether any operational
mitigation measures are to be required.
3.4.6 Bioaccumulation of Metals
Bioaccumulation of metals arsenic, cadmium, lead, and mercury (As, Cd, Pb,
Hg,) and organics (PCBs, PAHs,) shall be assessed in blue mussels (Mytilus
-------
edulis) in Boston Harbor using MWRA protocols for deployment and analysis
------
of contaminants (as approved by EPA). The MWRA's reference station at
Central Wharf shall be used. (Timing of this test may be coordinated with
reference site). This test shall be conducted during the first six months
of the project. At a minimum, caged mussels shall be deployed for at least
60 days at four sites at mid water column depth approximately 1000 ft from
the area occupied by all the disposal cells, as follows: two sites beyond
the most southerly disposal cell in the Inner Confluence and two sites
upstream of the most upstream cell in the Mystic River. The details of this
task shall be provided in advance to the Contracting Officer for review and
approval. The purpose of this requirement is to determine longer term
impacts to biological resources within a likely zone of impact from the
project than can be determined with chemical analysis of water samples
alone.
3.4.7 Plan Views of the Post-Disposal Plume
During the first month of disposal activity, plan views of the post-
disposal plume shall be generated using the plume tracking equipment
described in paragraph, "Plume Location Equipment" above. Such plan views
shall be provided showing areal extent of the plumes at the water surface,
at mid-water column and within a foot of the bottom. Date shall be gathered
between one and two hours following a disposal event on five occasions.
This documentation shall be provided as specified above in
SECTION 01135 Page 9
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
paragraph "ADMINISTRATIVE REPORTING REQUIREMENTS."
3.5 EXCEEDENCES OF WATER QUALITY CRITERIA
3.5.1 Acute and Chronic Water Quality in the Mixing Zone
The mixing zone for dredging and disposal of project sediments shall be 300
feet downcurrent from the activity. At this point, both acute and chronic
water quality criteria * shall be met. Acute criteria shall be met within the
mixing zone at all times. Monitoring for water column contaminants is detailed
in paragraphs "WATER COLUMN MONITORING - DISPOSAL OPERATIONS" and "WATER
COLUMN MONITORING - DREDGING OF DISPOSAL CELLS" above and the requirements are
designed to allow the Massachusetts Department of Environmental Protection to
determine whether water quality standards and criteria are being met;
* Acute criteria are defined as the one hour average concentration which
should not be exceeded more than once every three years on average; chronic
criteria are defined as the 4 day average concentration which should not be
exceeded more than once every three years, except that the PCB chronic
criterion is a 24 hour limit of exposure.
3.5.2 Exceedences of Water Quality Standards Attributable to Project
Activities
Exceedences of contaminant Water Quality Standards shall be attributed to
project activities when the sample concentration obtained down-current from
the project activity exceeds the particular standard and the sample
concentration is at least 30% higher than the appropriate reference sample
concentration. In the case of dissolved oxygen, real time measurements of D.O.
shall be used and failure to meet water quality standards shall be deemed
evident when there is a statistical difference at the 95% confidence interval
between the down-current sample mean and the appropriate reference sample
mean.
3.5.3 Repeat Samples
If water samples collected at the edge of the mixing zone fail to meet water
quality standards and this effect is attributed to project activities as
specified above, repeat samples shall be obtained under similar conditions
within 24 hours after the laboratory obtains the results of the first set of
samples. The repeat samples shall be analyzed for the parameter(s) of concern
and for TSS. Verification that the samples were obtained within the sediment
plume or that there was no plume shall be provided (see paragraph "Need for
Continued Monitoring" above). The analytical data shall be submitted as
specified above in paragraph, "Monitoring Data and Reports" within 36 hours
after the sample is received by the laboratory.
3.5.4 Implementation of Contingency Plan - Acute Water Quality Criteria
If two consecutive water samples collected in accordance with paragraph,
"Repeat Samples" above fail to meet acute water quality criteria as specified
in paragraph, "Exceedences of Water Quality Standards Attributable to Project
Activities" above, the Contractor shall take the following actions designed to
limit such exceedences: the mitigation measures included in the contingency
plan, as pre-approved by the Contracting Officer in coordination with the
Massachusetts Department of Environmental Protection, shall be immediately
implemented or all disposal activities shall cease in the affected work area
until an alternative proposal is provided to and approved, which shall then be
immediately implemented.
3.5.5 Implementation of Contingency Plan - Chronic Water Quality Criteria
SECTION 01135 Page 10
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
If two consecutive water samples collected in accordance with paragraph,
"Repeat Samples" above fail to meet chronic water quality criteria as
specified in paragraph, "Exceedences of Water Quality Standards Attributable
to Project Activities" above, then the following action shall be implemented:
work may continue provided chronic bioassay tests as specified in paragraph
"Bioassays of Material from Mystic River and Berths" above are undertaken
within 48 hours, or the Contracting Officer receives proposed mitigation
measures within 48 hours and mitigation measures approved by the Contracting
Officer are implemented within 48 hours of the approval. Such measures may
include operational controls such as reductions in dredge production rate,
silt curtain containment of the disposal cell or activity, and/or other
mitigation measures to be determined by the Contracting Officer in
consultation with the Massachusetts Department of Environmental Protection.
The Contracting Officer in coordination with the Massachusetts Department of
Environmental Protection will require water column testing to establish the
effectiveness of any operational controls implemented.
3.5.6 Exceedance of Total Suspended Solids (TSS) Criteria
If TSS exceeds the performance goal of 200 mg/1 at 500 ft downcurrent of the
disposal cell, the Contracting Officer in coordination with the Massachusetts
Department of Environmental Protection will evaluate the significance of the
TSS data and determine the requirements for additional mitigation.

SUBMITTAL PROCEDURES
PART 1 GENERAL
1.1 SUBMITTAL IDENTIFICATION
Submittals required are identified by SD numbers as follows:
SD-01 Data
SD-04 Drawings
SD-06 Instructions
SD-07 Schedules
SD-08 Statements
SD-09 Reports
SD-13 Certificates
SD-14 Samples
SD-18 Records
SD-19 Operation and Maintenance Manuals
1.2 SUBMITTAL CLASSIFICATION
Submittals are identified with submittal description (SD) numbers and are
classified as follows:
1.2.1 Government Approved
Governmental approval is required for extensions of design, critical
materials, deviations, equipment whose compatibility with the entire system
must be checked, and other items as designated by the Contracting Officer.
Within the terms of the Contract Clause entitled "Specifications and Drawings
for Construction," they are considered to be "shop drawings."
1.2.2 Information Only
All submittals not requiring Government approval will be for information only.
They are not considered to be "shop drawings" within the terms of the Contract
Clause referred to above.
1.3 APPROVED SUBMITTALS
The Contracting Officer's approval of submittals shall not be construed as a
complete check, but will indicate only that the general method of
construction, materials, detailing and other information are satisfactory.
Approval will not relieve the Contractor of the responsibility for any error
which may exist, as the Contractor under the CQC requirements of this contract
is responsible for dimensions, the design of adequate connections and details,
and the satisfactory construction of all work. After submittals have been
approved by the Contracting Officer, no resubmittal for the purpose of
substituting materials or equipment will be considered unless accompanied by
an explanation of why a substitution is necessary.
1.4 DISAPPROVED SUBMITTALS
SECTION 01300 Page 1
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
The Contractor shall make all corrections required by the Contracting
Officer and promptly furnish a corrected submittal in the form and number
of copies specified for the initial submittal. If the Contractor considers
any correction indicated on the submittals to constitute a change to the
contract, a notice in accordance with the Contract Clause "Changes" shall
be given promptly to the Contracting Officer.
1.5 WITHHOLDING OF PAYMENT
Payment for materials incorporated in the work will not be made if required
approvals have not been obtained.
PART 2 PRODUCTS (Not Applicable)
PART 3 EXECUTION
3.1 GENERAL
The Contractor shall make submittals as required by the specifications. The
Contracting Officer may request submittals in addition to those specified
when deemed necessary to adequately describe the work covered in the
respective sections. Units of weights and measures used on all submittals
shall be the same as those used in the contract drawings. Each submittal
shall be complete and in sufficient detail to allow ready determination of
compliance with contract requirements. Prior to submittal, all items shall
be checked and approved by the Contractor's Quality Control (CQC)
representative and each item shall be stamped, signed, and dated by the CQC
representative indicating action taken. Proposed deviations from the
contract requirements shall be clearly identified. Submittals shall include
items such as: Contractor's, manufacturer's, or fabricator's drawings;
descriptive literature including (but not limited to) catalog cuts,
diagrams, operating charts or curves; test reports; test cylinders;
samples; O&M manuals (including parts list); certifications; warranties;
and other such required submittals. Submittals requiring Government
approval shall be scheduled and made prior to the acquisition of the
material of equipment covered thereby. Samples remaining upon completion of
the work shall be picked up and disposed of in accordance with
manufacturer's Material Safety Data Sheets (MSDS) and in compliance with
existing laws and regulations.
3.2 SUBMITTAL REGISTER (ENG FORM 4288)
At the end of this section is one set of ENG Form 4288 listing items of
equipment and materials for which submittals are required by the
specifications; this list may not be all inclusive and additional
submittals may be required. The Contractor will also be given the submittal
register as a diskette containing the computerized ENG Form 4288 and
instructions on the use of the diskette. Columns "d" through "q" have been
completed by the Government; the Contractor shall complete columns "a" and
"r" through "t" and submit the forms (hard copy plus associated electronic
file) to the Contracting Officer for approval within 15 calendar days after
Notice to Proceed. The Contractor shall keep this diskette up-to-date and
shall submit it to the Government together with the monthly payment
request. The approved submittal register will become the scheduling
document and will be used to control submittals throughout the life of the
contract. The submittal register and the progress schedules shall be
coordinated.
3.3 SCHEDULING
Submittals covering component items forming a system or items that are
interrelated shall be scheduled to be coordinated and submitted
concurrently. Certifications to be submitted with the pertinent drawings
shall be so scheduled. Adequate time (a minimum of 21 calendar days
SECTION 01300 PAGE 2
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
exclusive of mailing time) shall be allowed and shown on the register for
review and approval. No delay damages or time extensions will be allowed for
time lost in late submittals.
3.4 TRANSMITTAL FORM (ENG FROM 4025)
The sample transmittal form (ENG Form 4025) attached to this section shall be
used for submitting both Government approved and information only submittals
in accordance with the instructions on the reverse side of the form. These
forms will be furnished to the Contractor. This form shall be properly
completed by filling out all the heading blank spaces and identifying each
item submitted. Special care shall be exercised to ensure proper listing of
the specification paragraph and/or sheet number of the contract drawings
pertinent to the data submitted for each item.

3.6 DEVIATIONS
For submittals which include proposed deviations requested by the Contractor,
the column "variation" of ENG FORM 4025 shall be checked. The Contractor shall
set forth in writing the reason for any deviations and annotate such
deviations on the submittals. The Government reserves the right to rescind
inadvertent approval of submittals containing unnoted deviations.
3.6.1 Substitutions
3.6.1.1 Basis of Contract
The contract is based on the materials, equipment, and methods described in
the contract documents.
3.6.1.2 Consideration of Substitutions
The Contracting Officer will consider proposals for substitutions of
materials, equipment, and methods only when such proposals are accompanied by
full and complete technical data and all other information required by the
Contracting Officer to evaluate the proposed substitution. Document each
request with complete data substantiating compliance of proposed substitution
with contract documents.
3.6.1.3 Representation
Requests constitute a representation that the Contractor:
a. Has investigated proposed product and determined that it meets or
exceeds, in all respects, specified product.
b. Will provide the same warranty for substitution as for specified
product.
c. Will coordinate installation and make other changes which may be
required for work to be completed in all respects.
d. Waives claims for additional costs which may subsequently become
apparent due to substitution.
3.6.1.4 Implied Substitutions
Substitutions will not be considered when they are indicated or implied on
shop drawings or product data submittals without separate written request, or
when acceptance will require substantial revision of contract documents.
3.6.1.5 Approval
Do not substitute materials, equipment, or methods unless such substitution
has been specifically approved in writing for this work by the Contracting
Officer.
SECTION 01300 Page 4
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT

The Contractor shall carefully control his procurement operations to ensure
that each individual submittal is made on or before the Contractor scheduled
submittal date shown on the approved "Submittal Register."
3.7 Deviations
For submittals which include proposed deviations requested by the Contractor,
the column "variation" of ENG Form 4025 shall be checked. The Contractor shall
set forth in writing the reason for any deviations and annotate such
deviations on the submittal. The Government reserves the right to rescind
inadvertent approval of submittals containing unnoted deviations.
3.8 CONTROL OF SUBMITTALS
The Contractor shall carefully control his procurement operations to ensure
the each individual submittal is made on or before the Contractor scheduled
submittal date shown on the "Submittal Register."

submittals will be identified as having received approval by being so stamped
and dated. Four copies of the submittal will be retained by the Contracting
Officer and two copies of the submittal will be returned to the Contractor.
3.10 INFORMATION ONLY SUBMITTALS
Normally submittals for information only will not be returned. Approval of the
Contracting Officer is not required on information only submittals. The
Government reserves the right to require the Contractor to resubmit any item
found not to comply with the contract. This does not relieve the Contractor
from the obligation to furnish material conforming to the plans and
specifications; will not prevent the Contracting Officer from requiring
removal and replacement of nonconforming material incorporated in the work;
and does not relieve the Contractor of the requirement to furnish samples for
testing by the Government laboratory or for check testing by the Government in
those instances where the technical specifications so prescribe.

3.2 QUALITY CONTROL PLAN
3.2.1 General
The Contractor shall furnish for review by the Government, not later than 15
days after receipt of notice to proceed, the Contractor Quality Control (CQC)
Plan proposed to implement the requirements of the Contract Clause entitled
"Inspection of Construction." The plan shall indentify personnel, procedures,
control, instructions, test, records, and forms to be used. The Government
will consider an interim plan for the first 14 days of operation. Construction
will be permitted to begin only after acceptance of the CQC Plan or acceptance
of an interim plan applicable to the particular feature of work to be started.
Work outside of the features of work included in an accepted interim plan will
not be permitted to begin until acceptance of a CQC Plan or another interim
plan containing the additional features of work to be started.
3.2.2 Content of the CQC Plan
The CQC Plan shall include, as a minimum, the following to cover all
construction operations, both onsite and offsite, including work by
subcontractors, fabricators, suppliers, and purchasing agents:
a. A description of the quality control organization, including a chart

suppliers, and purchasing agents. These procedures shall be in
accordance with Section 01300 SUBMITTAL PROCEDURES.
e. Control, verification, and acceptance testing procedures for each
specific test to include the test name, specification paragraph
requiring test, feature of work to be tested, test frequency, and person
responsible for each test. (Laboratory facilities will be approved by
the Contracting Officer.)
f. Procedures for tracking preparatory, initial, and follow-up control
phases and control, verification, and acceptance tests including
documentation.
g. Procedures for tracking construction deficiencies from identification
through acceptable corrective action. These procedures will establish
verification that identified deficiencies have been corrected.
h. Reporting procedures, including proposed reporting formats. See
paragraph IMPLEMENTATION OF GOVERNMENT RESIDENT MANAGEMENT SYSTEM FOR

a task which is separate and distinct from other tasks and has separate
control requirements. It could be identified by different trades or
disciplines, or it could be work by the same trade in a different
environment. Although each section of the specifications may generally
be considered as a definable feature of work, there are frequently more
than one definable feature under a particular section. This list will be
agreed upon during the coordination meeting.
3.2.3 Acceptance of Plan
Acceptance of the Contractor's plan is required prior to the start of

1.4 EXISTING CONDITIONS
1.4.1 Material to be Dredged
Dredged material is referred to in these specifications as either "soft"
material, "hard" material, "rock" or "debris." The material to be removed to
accomplish the specified dredging work is anticipated to be silt, sand, clay,
glacial till and rock. Requirements for the excavation of rock material are
specified in Section 02491 UNDERWATER DRILLING AND BLASTING. The Contractor is
expected to examine the site of the work and determine the character of the
materials to be dredged.
1.4.2 Results of Explorations
Explorations to determine the character of materials to be removed, have
SECTION 02482 Page 2
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
been made by the Government for selected areas of this project. Graphic logs
of explorations are shown on the contract drawings. Grain size analysis curves
are attached at the end of this section. Although the results of such
explorations are representative of subsurface conditions at their respective
locations and for their respective vertical reaches, local variations in the
subsurface materials are to be expected and, if encountered, will not be
considered materially different within the purview of the contract.

which are made known to the Contractor prior to dredging, and that are to be
retained, shall be protected from damage during dredging, and if damaged shall
be satisfactorily repaired by the Contractor at no additional cost to the
Government. Prior to commencement of dredging, the Contractor shall coordinate
with the Contracting Officer and the applicable utility company to mark the
exact locations of existing utilities, and establish in detail the proposed
method of protecting the existing utilities. In the event that the Contractor
damages any existing utility lines that are not shown on the drawings or the
locations of which are not known to the Contractor, report thereof shall be
made immediately to the Contracting Officer. If the Contracting Officer
determines that repairs shall be made by the Contractor, such repairs will be
ordered under the Contract Clause entitled "DIFFERING SITE CONDITIONS."
1.4.5.3 Removal of Utility Lines
The Contracting Officer and the applicable utility company or owner shall be
notified in ample time to mark the exact locations of existing utilities to be
removed under this contract, and establish in detail the proposed method of
protecting any existing adjacent utilities.
1.5 OVERDEPTH AND SIDE SLOPES
1.5.1 Allowable and Required Overdepth
To cover the inaccuracies of the dredging process, material actually removed
from within the specific areas to be dredged, to depths as specified below for
allowable overdepth, will be estimated and paid for at the contract price.
Allowable overdepth dredging will be permitted to a depth of not more than 1.7
feet for all dredging will be permitted to a depth of not more than 1.7 feet
for all dredging areas shown, except in areas of rock excavation. There is a
required overdepth for rock excavation only. Overdepth dredging of rock will
be required to a depth of not more than 2 feet below the project depth in all
dredging areas where rock is encountered. An allowable overdepth will be
permitted to a depth of not more than 2 feet below the required overdepth in
all areas where rock excavation is performed. Allowable and required overdepth
dredging will be measured and paid for at the applicable contract price in the
same manner as specified for the overlying dredge material.
1.5.2 Side Slopes
1.5.2.1 Side Slopes at Disposal Cells
The Contractor shall construct disposal cells with side slopes of 1 vertical
to 2 horizontal. However, the Contractor may construct the side slopes steeper
than 1 vertical to 2 horizontal to increase cell volume, as approved by the
Contracting Officer on a case by case basis. Contracting Officer approval will
be based on the impact steeper slopes will have on the stability of adjacent
structures and the stability of the cell.. Cells shall be constructed to
maintain a 50 foot separation from the edge of the
SECTION 02482 Page 4
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
federal channel limits and all adjoining cells.
1.5.2.2 Side Slopes at Berths
Material actually removed, within the limits approved by the Contracting
Officer, to provide for final project depth at the land side of the berths and
1 vertical on 3 horizontal elsewhere, but not in excess of the amount
originally lying above these limiting side slopes, will be estimated and paid
for, whether dredged in the original position or by dredging the space below
the pay slope plane at the bottom of the slope for upslope material capable
of falling into the cut. In computing the limiting amount of side slope
dredging, an overdepth of 1.7 feet measured vertically will be used. The
above is not to be taken as a guarantee that all slopes will stand on a slope
of 1 vertical and 3 horizontal. The Contractor shall make his own
determination as to what the angle of repose will be on all side slopes. The
Contractor will be required to exercise care in dredging near wharfs and piers
so as not to overdredge to such an extent as to undermine the structures or in
any way impair the stability of such structures.
1.5.3 Excessive Dredging
Material taken from beyond the limits as extended in paragraph OVERDEPTH AND
SIDE SLOPES above will be deducted from the total amount dredged as excessive
overdepth dredging, or excessive side-slope dredging for which payment will
not be made.
1.5.4 Protection of Existing Structures
The Contractor shall conduct the dredging operation such that it does not
undermine, weaken or otherwise impair existing structures located in or near
the areas to be dredged. The Contractor shall investigate the existing
structures at the site and plan the dredging work accordingly. The Contractor
shall be held responsible for any damage to the existing facilities resulting
from dredging. The Contractor could be directed by the Contracting Officer to
fill overdredged areas with clean material at no cost to the Government.
Filling of overdredged areas may require permit modifications to be obtained
by the Contractor.
1.6 INSPECTION OF DISPOSAL
No disposal shall be done unless an inspector, approved by the Contracting
Officer is present. The inspector shall be available on a full-time basis to
cover all phases of operations in connection with disposal of the dredged
materials.
The Contractor shall be responsible for and provide qualified disposal
inspection services at no additional cost to the Government. The Contractor
shall notify the Contracting Officer of the names of the Corps of Engineers
Certified inspectors to be used prior to commencement of work. Every discharge
of dredge material must be officially witnessed and properly documented by an
onboard inspector who has been trained by, and who holds a current
certification from the New England District, Army Corps of Engineers. Failure
to adhere to this requirement will be considered a serious violation of this
contract and cause for an immediate stop-work order by the Contracting Officer
and which could precipitate substantial penalties including but not
necessarily limited to fines, withholding of funds and/or non-payment due to
misplaced materials.
1.6.1 Communication
The Contractor shall provide the Contracting Officer with 2 hand-held VHF
radios capable of communicating with the Contractor's marine plant for the
duration of the contract.

Officer will direct the shifting or moving of dredges or the interruption of
dredging operations to accomodate the movement of vessels
SECTION 02482 Page 6
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
and floating equipment, if necessary. The Contractor shall comply with all
requests from the Contracting Officer to move or interrupt dredging operations
for a reasonable time period at on additional cost to the Government. During
winter months there is heavy usage of the Chelsea River by tankers;
coordination with docking pilots will be necessary on a daily basis.
3.1.4 Ranges, Gages, and Lines
Furnish, set, and maintain ranges, buoys, and markers needed to define the
work and to facilitate inspection. Establish and maintain gages in locations
observable from each part of the work so that the depth may be determined.
Suspend dredging when the gages or ranges cannot be seen or followed. The
Contracting Officer will furnish, upon request by the Contractor, survey
lines, points, and elevations necessary for the setting of ranges, gages, and
buoys.
3.1.5 Method of Communication
Provide a system of communication between the dredge crew, the
sampling/monitoring contractor, the towboat, the Independent Observer, the
disposal inspector, and the Contracting Officer. Portable two-way marine
radios are acceptable.
3.1.6 Debris Management
A debris management plan shall be developed, accepted by the Contracting
Officer and followed by the Contractor. The plan shall be submitted as part of
the Environmental Protection Plan, as specified in Section 01130 ENVIRONMENTAL
PROTECTION. This plan shall include accommodation for specific removal of the
debris identified in paragraph "Clearing of Main Ship Channel Debris" below,
as well as latent debris discovered during dredging operations. Each day
during dredging operations, the Contractor shall use a boat to collect and
remove floating debris resulting from project activities. Floating debris
shall also be removed from within barges. Debris removed from the bottom
during dredging operations, which is not suitable for disposal in the cells or
at the Massachusetts Bay Disposal Site (MBDS), shall also be collected and
removed from the site. Abandoned and broken piles within 25 feet of a
structure shall be broken or cut off rather than extracted. Containers for
temporary storage of the collected debris shall be maintained on the dredge or
support barge.
3.1.6.1 Clearing of Main Ship Channel Debris
An obstruction has been identified in the -35 - foot portion of the Main Ship
Channel opposite Castle Island, as shown on the contract drawings. The
Contractor shall locate and remove the debris. A plan for locating, removing,
and disposing of the debris shall be included in the Contractor's "Debris
Management Plan".
3.1.7 Underwater Diving Operations
In the event that underwater diving operations become necessary due to the
work of this contract, such operations shall be conducted in accordance with
Section 02492 UNDERWATER WORK.
3.2 DREDGING BOSTON HARBOR
Consistent with the environmental dredging window restrictions, the Contractor
shall begin by constructing the initial disposal cell. Once the disposal cell
is excavated, dredging of the Boston Harbor Channels and berths shall
commence.
3.2.1 Dredging of Soft Material
SECTION 02482 Page 7
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
An environmental bucket shall be used for dredging the soft material from
Boston Harbor. No dragging of material will be allowed except as directed by
the Contracting Officer. The soft material shall be transported in scows and
deposited in the in-channel disposal cells shown on the drawings. Construction
of the in-channel disposal cells is specified below in paragraph "CONSTRUCTION
OF IN-CHANNEL DISPOSAL CELLS" The maximum distance soft material must be
transported will not exceed 7 nautical miles. Placement of soft material in
disposal cells will only be permitted during the interval 1 hour before high
tide to 2 hours after high tide. No disposal shall take place during passage
of tugboat in escort of large vessels, such as tankers, while the vessel is
within 1000 feet of a disposal cell until the Contracting Officer directs
otherwise. Use of a fully automated horizontal positioning system capable of
locations within 1.0 meter of the true position is required to ensure proper
positioning of the scows over the disposal cell.
3.2.2 Dredging of Hard Material
The environmental bucket is required only for the removal of soft material.
Hard material shall be placed in dump scows and transported to the
Massachusetts Bay Disposal Site and disposed at a taut wire buoy. The location
of the Mass Bay Disposal Site is shown on the drawing attached at the end of
this section. The National Marine Fisheries Service (NMFS) has placed specific
conditions governing the use of the Massachusetts Bay Disposal Site: See
Section 01130 ENVIRONMENTAL PROTECTION for information on the NMFS conditions
governing the use of the Massachusetts Bay Disposal Site.
3.2.3 Dredging of Berth Areas
The Contractor shall dredge the berth areas shown on the drawings. The limits
of the berth areas shall be verified with the berth owners and the Contracting
Officer prior to dredging. Dredging of the berth areas shall be performed as
the adjacent Federal Channel is dredged. The requirements listed above for
dredging of soft and hard material apply to dredging of the berth areas.
However, prior to removing the dredge plant from the site, the Contractor will
make a final pass along the fender face to remove material expected to slough
off of the slope under the piers. Sloughed material removed from the trench
shall be disposed in the in-channel disposal cells. The Contractor is directed
not to dig below the overdepth elevation.
3.2.4 Underwater Utilities
Utility locations which are known are shown on the drawings. Utility companies
contacted for information included: Boston Edison, Bell Atlantic, MWRA, Boston
Gas, Boston Water and Sewer Commission, and the MBTA. Water and sewer
pipelines, cables, and a gas siphon were identified in the Chelsea Creek area
and cables were identified in the Reserved Channel. The Contractor shall note
the location of these utilities and take special precautions when dredging in
their vicinity. "No Spud" areas are marked on the contract drawings for
protection of known utilities. The Contractor shall not dredge the area of
channel over the MWRA "Section 8" waterline as noted on the contract drawings.
The Contractor shall dredge the area of channel over the Boston Gas Siphon to
a depth of -35 feet with an allowable overdepth of 1.7 feet, as shown on the
contract drawings. To prevent damage to the gas siphon, the Contractor is
directed not to dig below the overdepth elevation. Removal of the "Old Section
38" abandoned water tunnel shall be completed prior to dredging the area over
the gas siphon.
3.2.5 Removal of Abandoned Water Tunnel
The Contractor shall verify the location and remove the abandoned MWRA
concrete lined water tunnel known as "Old Section 38" to the limits as
SECTION 02482 Page 8
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
shown on the contract drawings. The Contractor shall submit a proposal
detailing the methods he intends to implement to accomplish demolition and
removal of the water tunnel. Demolition methods may include underwater
cutting, breaking, controlled blasting and other methods approved by the
Contracting Officer. Underwater blasting shall be performed in accordance with
Section 02491 UNDERWATER DRILLING AND BLASTING, with peak particle velocities
no greater than 1.0 inch per second, due to the proximity of the gas siphon.
3.3 CONSTRUCTION OF IN-CHANNEL DISPOSAL CELLS
3.3.1 Work Restrictions for the Protection of Fisheries
Cell excavation and disposal activities located upstream of the Tobin Bridge
in the Mystic River and at cells 1, 2, and 3 in the Inner Confluence occurring
from February 15 to June 15 shall be conducted with a fish startle system,
sonar, and an approved fisheries observer. However, the Contractor has the
option of not performing cell excavation and disposal activities at these
cells during the above time period; provided all contract work can be
performed within the specified prosecution period. See Section 01130
ENVIRONMENTAL PROTECTION for fisheries observer, fish startle system and,
sonar equipment requirements. No restrictions are placed on work for the
protection of fisheries in the Chelsea River upstream of the McArdle Bridge
(Meridian Street).
Cell excavation and disposal activities will not be permitted during the
period February 15 to June 15 of any year at cell locations 3A, 4, 5, 6, 7, 8,
and 9 in the Inner Confluence, as shown on the contract drawings.
3.3.2 Location and Number of Cells
All dredged soft material, which by definition is unsuitable for unconfined
ocean disposal, shall be placed in cells dredged beneath the federal channels
and the unsuitable material shall be capped. Capping of any cell shall be
completed within 30 days of the start of cap placement. The soft material may
swell as much as 50% prior to consolidation within the cells and the cells
shall be sized accordingly. After actual swell and consolidation data is
obtained from Government and Contractor surveys during the prosecution of the
work, the Contractor shall use that data to size future cells.
The disposal cells shall be located in the areas shown on the drawings.
Coordinates delineating the limits of each of the constructed in-channel
disposal cells shall be furnished to the Contracting Officer. The Contractor
shall size the disposal cells to contain all soft material dredged, including
material which may slough off of the slope under the piers adjacent to the
berths and incidental hard material if dredged along with the soft material.
Post-dredge soundings will be provided by the Government for both berths and
the disposal cells in order to calculate soft material volumes before dredging
of the hard material. It is the Contractor's responsibility to ensure adequate
disposal cell capacity exists for all soft material to be dredged. The
Contractor will be required to continue to dredge additional disposal cells at
his expense for disposal of all of the soft material dredged. However, cell
construction shall be programmed to ensure that no empty or partially filled
cells remain at the completion of soft material disposal operations. A table
of disposal cell locations and proposed cell depths is attached at the end of
this section. The coordinates given in the table serve as a guide only and
will be adjusted by the Contracting Officer dependant on the actual field
conditions encountered.
3.3.3 Verification of Electronic Positioning System
Visual indicators shall be deployed clearly delineating the disposal cells
during all periods of active disposal into the cells, until the accuracy of
SECTION 02482 Page 9
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
electronic positioning equipment is verified by the Contracting Officer. Use
of differential global positioning system (DGPS) accurate to 1 meter or
better, with real time graphic display will satisfy this condition. The
purpose of this requirement is to enable the dredge operator and regulatory
agency inspectors to verify that disposal occurs into the permitted cells.
3.3.4 Cell Filling at High Tide
Sediment disposal into any cell shall occur only during high tide, defined for
this activity as the time from 1 hour before to 2 hours after the predicted
Boston high tide time. The purpose of this requirement is to provide maximum
dilution and minimal dispersion and transport of fine contaminated sediment
during disposal operations. If an alternative technology is proposed and
approved by the Contracting Officer that allows the material to be placed
directly in the disposal cell without passing through the water column,
disposal may occur at any time during the tidal cycle.
3.3.5 Cell Construction Surveys by the Government
The following bathymetric surveys will be conducted by the Government during
cell construction: A pre-dredge survey will be made by the Government prior to
commencement of dredging operations; an after-dredge survey will be made by
the Government after the dredging of the soft material from the cells; a
survey will be made by the Government immediately prior to the commencement of
cell capping; and an after-dredge survey will be made by the Government after
the sand cap is placed. The Contractor shall notify the Contracting Officer a
minimum of 5 days prior to completion of an item of work listed above that
requires a Government survey to allow adequate time to prepare for the
surveys. The Contractor shall also allow a reasonable amount of time for the
completion of each Government survey. For the first cell, the range of the
survey will be 1 barge length (up to 300 feet) beyond the perimeter of the
cells. For subsequent cells, the range of the survey will be at least 50 feet
beyond the perimeter of the cell. If a placement problem is detected, then the
Contractor will be required to remove all misplaced material and deposit it in
the cell and to submit a revised positioning plan for Contracting Officer
approval.
3.3.6 Cell Construction Surveys by the Contractor
The following bathymetric surveys shall be conducted by the Contractor during
cell construction: After dredging of hard material from cells; after placement
of soft material in cells; and within 2 weeks after capping as specified below
in paragraph, "Cap Thickness and Coverage Determination." Surveys shall be run
on 25 foot intervals, with all subsequent surveys done on the same spacing,
tracks and reference lines. Copies of all Contractor surveys shall be
submitted to the Contracting Officer within 2 days after completion of the
respective survey. For the first cell, the range of the Contractor survey
shall be 1 barge length (up to 300 feet) beyond the perimeter of the cells.
For subsequent cells, the range of the Contractor survey will be at least 50
feet beyond the perimeter of the cell. If a placement problem is detected,
then the Contractor will be required to remove all misplaced material and
deposit it in the cell and to submit a revised positioning plan for
Contracting Officer approval. Further surveys by the Contractor may be
required to verify accurate placement of the soft material and the cell cap.
3.3.6.1 Documentation
The results of bathymetric surveys performed by the Contractor and by the
Government shall be combined and documentation provided by the Contractor for
all cells as follows:
a. Cell bottom elevation and status (i.e., active disposal, completed
SECTION 02482 Page 10
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
disposal, completed capping, etc.) of all cells shall be shown in matrix
chart form, similar to the chart attached at the end of this section;
b. the matrix chart shall be provided to the Contracting Officer within 7
business days of completion of the caps for each of the first three cells
and thereafter as specified below;
c. the matrix chart shall be updated and provided to the Contracting
Officer every three months thereafter throughout the remainder of the
project;
d. Contractor and Government bathymetric survey data shall be shown in
graphic form for each cell where disposal has occurred. This graphic
report shall be provided to the Contracting Officer within 30 days of
completion of each cap.
3.3.7 Passage of Vessels
No cell shall be filled during passage of tug boat in escort or tanker vessels
while the vessel is within 1000 ft of the disposal cell.
3.3.8 Initial In-channel Disposal Cell
Soft material overlying the area of the initial in-channel disposal cell shall
be dredged using an environmental bucket and the material temporarily stored
in tight scows or other suitable containers within a reasonable distance of
the disposal cell. The environmental bucket shall conform to the performance
standards as indicated in Section 01135 WATER QUALITY MONITORING AND CONTROL.
3.3.9 Dredging of Hard Material in Cells
After the soft material is removed the Contractor will be allowed to change
buckets to remove the underlying hard material. The hard material shall be
placed in dump scows and transported to the Massachusetts Bay Disposal Site
for disposal at a taut wire buoy.
3.3.10 Placement of Soft Material in Cells
Overlying soft material, stored in scows during construction of the initial
disposal cells, shall be carefully placed in the disposal cells as specified.
Placement of soft material within the disposal cells shall be such that
mounding of the soft material is minimized. The Contractor shall redistribute
all mounds of soft material that project above the -45 foot MLLW datum to
other areas of the disposal cells.
3.3.11 Documentation
The origin of the last barge load of sediment placed in each cell shall be
documented and provided to the Contracting Officer with the final project
report, as required by Section 01175 WATER QUALITY MONITORING AND CONTROL.
3.3.12 Capping of In-Channel Disposal Cells
3.3.12.1 General
After placement of soft material in a disposal cell, the Contractor will be
required to wait a minimum of 30 days, but not more than 60 days, to allow the
soft material to settle before closing the cell. Each cell shall be closed by
construction of a cell cap, consisting of 2 uniform layers of the specified
clean granular fill material. Each cell cap shall be constructed a minimum of
3 feet thick over the top of the soft material. Capping of a cell shall be
completed within 30 days of the start of cap placement. The Contractor shall
submit a capping plan for approval prior to placement of
SECTION 02482 Page 11
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
the cap. Cap material shall be as specified above. Precautions shall be taken
to ensure that no portion of the cap projects above -42 feet MLLW, Portions of
the cap protruding above -42 MLLW may require removal as directed by the
Contracting Officer at the expense of the Contractor.
In addition to capping the cells constructed by the Contractor under this
contract, the Contractor shall complete the cap on the southern portion of the
existing disposal cell of maintenance material constructed in July 1997.
Final capping of this cell shall be completed within two months of the channel
deepening in the Inner Confluence. However, completion of this in capping the
first 3 disposal cells. The location of the existing cell is shown on the
contract drawings. Completion of the cap on the existing cell shall comply
with requirements for capping of Contractor constructed cells.
3.3.12.2 Cap Placement and Integrity
The disposal cell cap shall be placed gradually, in 2 uniform layers, so as to
minimize disturbance to the unconsolidated soft material in the disposal
cells. In order to calculate drift of cap material during placement, the
Contractor shall measure and record real time current measurements at the
surface, mid-level and at the bottom of the water column in the immediate area
of the capping operation. The cap placement method shall be adjusted to ensure
necessary cap thickness over the entire cell area. The Contractor shall ensure
that the edges of the cap meet the minimum thickness requirement. Further,
there shall be no mechanical disturbance of the sand cap by means including
but not limited to drag bar, clamshell bucket, and barge spudding, unless such
disturbance is pre-approved by the Contracting Officer. Obtaining core samples
will not be considered "mechanical disturbance".
3.3.12.3 Cap Thickness and Coverage Determination
Within two weeks of capping, each of the first three disposal cells shall be
surveyed by the Contractor using a combination of methods to verify to the
Government that each cap has three feet of thickness over a minimum of 90% of
the cell and that the zone of mixed dredged silt and cap material (i.e.,
within the three foot cap) is less than 12 inches. Methods used to provide
this verification shall include acoustic sub-bottom profiling, vibracore
sampling consisting of a minimum of 4 cores per acre, and may include other
proven technologies. Vibracore sampling shall consist of 4 cores per acre,
with a minimum of 3 cores per cell. The location of the cores shall be as
selected by the Contracting Officer Unproven technologies may be acceptable
for cap thickness and coverage determination provided proper validation is
furnished to the Contracting Officer for his approval. After the Contractor
has proven the effectiveness of his cap thickness and coverage determination
methodology for the first three cells, the Contracting Officer will approve
the methodology for cell cap verification for all other project cells.
The Contracting Officer will determine the effectiveness of the Contractor's
cap thickness and coverage determination methodology, and will so acknowledge
in writing.
If the Contractor's cap thickness and coverage determination methodology has
not been approved within three months of completion of the first cell cap,
then disposal in all other project cells shall cease. New cell construction
will not be permitted until new or additional cap placement verification
methodology is proposed by the Contractor, accepted by the Contracting Officer
for trial, and its effectiveness demonstrated by the Contractor on completed
cells.
If data collected indicates that a completed cell is not in compliance with
these specifications, the Contractor shall continue capping operations and

cap verification testing until contract compliance is demonstrated.
3.4 TOW BOATS AND SCOWS
See also Section 01600 PLANT AND EQUIPMENT
3.4.1 Tow Boats
All tow boats used for towing to disposal areas shall be equipped with DGPS
and track recording navigational equipment of approved equivalent electronic
navigation equipment, radar, corrected compass, marine radio, and depth
sounding equipment which is to be maintained in operating condition during
each tow. The tow boats utilized by the Contractor for this purpose shall be
of a size adequate for towing in the open ocean and shall have necessary
reserve power for maneuvering with scows and under emergency conditions as
well as for control of scows at the disposal point.
3.4.2 Scows
The Contractor shall provide and maintain markings on all scows clearly
indicating the draft of the scow and shall provide scow cards for each scow
used on the contract work. The scow cards shall show dimensions and volumes
of individual pockets of scows and total volumes for varying depths below
coaming or top of pockets. The Contractor shall also provide draft verses
displacement curves for all scows. This is to enable the Contracting Officer
personnel to make determination of scow volume and corresponding drafts
under partial and full load conditions. These measurements are to be made at
the time of initial use of each scow. This information will then be
furnished to disposal inspectors to enable them to estimate scow volume from
draft of scows for each scow being towed to the disposal area. The scow
volume estimates are for use in connection with disposal area monitoring
studies and are not intended to be used in determining quantities dredged.
At the beginning of the work and as additional scows arrive on the project,
sufficient time shall be allowed by the Contractor and assistance of
Contractor personnel shall be made available by the Contractor for the
purpose of obtaining the measurements of each scow under various partial and
full load conditions. During the entire period of contract work, the
Contractor shall provide and maintain sufficient spot or floodlights to
permit the reading of the draft on the sides of scows at bow and stern from
the tow boat at night and when visibility is impaired. The draft readings
will be required for each scow towed to the disposal area and will be made
by the disposal inspector. The Contractor shall ensure that adequate time is
allowed by the tow boat captain for these readings to be obtained.
3.4.2.1 Scow Pocket Doors
Due to the fine nature of the dredge material, the Contractor will be
required to achieve proper closure and adequate tightness of pocket doors to
eliminate any seepage or leakage of material. The use of plastic material to
cover cracks in scow pockets will not be allowed.

1.10 PROJECT/SITE CONDITIONS
1.10.1 EXISTING CONDITIONS
The rock to be excavated is from the geologic formation locally known as the
Cambridge slate in early literature and as argillite in later references.
Argillite is used as the classification for this project. The bedrock map of
the area by the United States Geological Survey describes the argillite as
gray, laminated to massively bedded with poorly developed bedding-plane
partings, having locally imperfect slaty cleavage, and with minor inter bedded
sandstone and (or) quartzite.
Bedrock was encountered by several borings in the Mystic River Channel and in
the Boston Army base vicinity as described on the graphic logs shown on the
drawings. The bedrock surface is expected to be irregular and its actual
occurrence within dredge depth is unknown.
SECTION 02491 Page 6
BOSTON HARBOUR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
Contractors are expected to examine the site of the work, cores and logs, and,
after investigation, decide for themselves, the character of materials and
make their bids accordingly. The Government assumes no responsibility for the
types of material encountered, nor does it guarantee that other materials will
not be encountered in performance of the work. The removal cost of such other
materials shall be included in the Bid Prices. Other subsurface data are
referenced in Section 02482 Dredging.

PART 3 EXECUTION
3.1 EXAMINATION
3.1.1 Preblast Survey
The Contractor shall provide one qualified person from his organization and
his specialist on vibration control to work as a team with a representative of
the Contracting Officer in making a preblast structural survey. A
representative sample of structures (approximately 20 percent), as determined
by the Contractor, that could receive seismic motion greater than 0.5 inch per
second or airblast over pressure greater than 0.01 psi, shall be inspected and
their condition documented. The Contractor may perform additional preblast
surveys of additional structures, at his option and at no additional expense
to the Government. All existing outstanding structural defects such as broken
windows shall be photographically documented. Video photography may be
utilized in addition to still photographs to augment particularly large areas
of poor condition, but shall not be used in lieu of the written reporting
procedure. Each structure shall be documented as to its construction,
foundation type, condition, and closest distance to rock removal locations.
The preblast survey inspection methods will be subject to the approval of the
Contracting Officer. The Contractor shall prepare a preblast survey report and
submit the report to the Contracting Officer. All necessary rights of entry to
properties subject to a preblast survey shall be obtained by the Contractor.
Owners of all properties that could receive seismic motion greater than 0.5
inch per second or airblast over pressure greater than 0.01 psi shall be
notified prior to the commencement of blasting.
3.2 PREPARATION
3.2.1 Test Blast Program
A test blast program shall be conducted by the Contractor, consisting of a
minimum of three test blasts in each area of rock excavation. The purpose of
the test program is to allow the Contractor to establish the desired effects
for excavation, the safe limits of vibration and airblast over-pressure. The
test blast program shall be conducted and reported in strict accordance with
procedures outlined in these specifications covering blasting methods and
vibration control.
No test blasting shall be started until after the location for the individual
test blasts has been reviewed and approved by the Contracting Officer.
Test blasting in the Mystic River and Inner Confluence, if necessary, will be
permitted only between June 16 of one year through February 14, inclusive, of
the next year.
The test event shall begin with a small number of charges and extend upward to
the maximum yield to be used. The final test event shall simulate as close as
practicable the explosive charge type, size, overlying water depth, charge
configuration, charge separation, initiation methods, and emplacement
conditions anticipated for the largest detonations. Upon any
SECTION 02491 Page 7
BOSTON HARBOR NAVIGATION IMPROVEMENT AND BERTH DREDGING PROJECT
evidence of any damage to preblast survey structures, test blasting shall
cease until the Contracting Officer has been notified and adjustments made.
One copy of the record for the test blasts shall be submitted in tabular form
to the Contracting Officer.
After the series of test blasts, the Contractor shall examine the
representative structures of the preblast survey as previously specified. All
new damage resulting from the test blasting shall be reported in detail to the
Contracting Officer, including photographs.
At the conclusion of the test blast program, the Contractor shall examine all
reports, surveys, test data, and other pertinent information: the conclusions
reached shall be the basis for developing a completely engineered procedure
for blasting. The procedures shall include sketches showing blasting patterns,
weights and explosives, wiring, and charge emplacement. The developed
procedure shall be submitted for review to the Contracting Officer, and upon
completion of the review and acceptance, it shall be appended to and become a
part of the blasting plan. A period of seven days will be required for review
and acceptance by the Contracting Officer of the proposed procedure. Such
review period shall not be the basis for a claim against the Government for
delay. In no event shall operational blasting proceed until the developed
procedure for blasting has been reviewed and accepted by the Contracting
Officer. If the procedure is not acceptable, the Contractor shall revise and
resubmit the procedure. The Contracting Officer will require five days for
review and acceptance of the revised procedure.
3.3 BLASTING METHODS AND PROCEDURES
3.3.1 General
The Contractor shall take appropriate measures for controlling blast damage
which shall include but are not limited to:
a. Choosing a suitable ignition pattern with millisecond delay detonators
to minimize the instantaneous impulse.
b. Using lower charges in the first detonating delay than those in
subsequent delays.
c. Taking precautions to avoid flashover, which shall include the
following measures unless otherwise allowed by the Contracting Officer:
(1) Keeping the top of the hole uncharged for a depth equal to at
least one-half the burden width.
(2) Using low sensitivity explosives in the entire pattern or loading
the holes alternatively with high and low sensitivity explosives.
(3) Inspecting the ignition system using ground fault testing.
d. One person shall be charged with overall development of pattern
design, loading and connection the explosives and may supervise
subordinates, who also shall have blasting credentials to accomplish the
same duties.
e. Proper lighting plant shall fully illuminate the drilling and loading
barge(s) when work is being conducted without full daylight. Drilling
shall be vertical with a hole diameter of 6-inches or smaller. Blast holes
shall be accurately positioned a Differential Global Positioning System
(DGPS) and recorded with electronic drill monitoring.
f. The Contractor shall determine a safe means to drill, load and connect
the firing lines to the submerged borings. The vertical
SECTION 02491 Page 8
BOSTON HARBOR NAVIGATION IMPROVMENT AND BERTH DREDGING PROJECT
loading casing shall be seated into rock and accurately positioned be
modern survey procedures.
3.3.2 Blasting Control
3.3.2.1 Submittals
On a semi-monthly basis, the Contractor shall submit in tabular form a record
for each blast which shall consist of positively identified, date and time and
location of blast, amount of explosives used, peak particle velocity, and all
other data necessary to adequately control blasting operations. A memorandum
or telephone report on vibration intensity shall be submitted within 24 hours
when specifically requested by the Contracting Officer or without request when
such intensity exceeds a peak particle velocity of 1.5 inches per second.
3.3.2.2 Vibration Control
The vibration specialist shall adopt appropriate measures for blast damage
reduction and shall be fully involved in a design of the test blasting and
monitoring program and the final production blasting and monitoring program.
As a minimum, seismic monitoring equipment shall be placed on the tower and
another lower location on or in the Tobin Bridge for monitoring blasting in
the Mystic River, and at the Conley Terminal and Boston Army Base for
monitoring blasting in the Reserved Channel. Other monitoring stations shall
be set up as necessary to gain reliable data on blast effects to structures
deemed sensitive by the vibration specialist, Contractor, or Contracting
Officer. Fourteen days shall be allowed for the Contracting Officer to review
and accept the final blasting plan. The vibration specialist shall be retained
throughout the operational program to provide and vertify round-by-round
blasting records.
Millisecond delay caps shall be used on all blasting work.
Blasting shall be controlled in such a manner that the maximum ground
vibration level at any structure which is vulnerable to damage shall not
exceed a zero-to-peak particle velocity of 1.0 inches per second nor an
energy ratio of 1.0. The instrumentation shall record all three orthoganal
components (vertical, radial, and transverse with respect to the location of
the blast) of particle velocity direct (or shall have sufficient resolution of
acceleration or displacement such that particle velocity can be readily and
accurately determined from the records). The instantaneous vector sum of the
three directional components of vibration will be used to compute the maximum
vibration level.
3.4 DISPOSAL OF DREDGED ROCK MATERIAL
Rock material shall be placed in dump scows and transported to the
Massachusetts Bay Disposal Site and disposed at a taut wire buoy. The location
of the Mass Bay Disposal Site is shown on the drawing attached at the end of
Section 02482 DREDGING. The National Marine Fisheries Service (NMFS) has
placed specific conditions governing the use of the Massachusetts Bay Disposal
Site: See Section 01130 ENVIROMENTAL PROTECTION for information on the NMFS
conditions governing the use of the Massachusetts Bay Disposal Site.
