Exhibit 99.1


Report of Independent Public Accountants



To the Stockholders of Perini Corporation:

We have audited the  accompanying  combined balance sheets of the joint ventures
identified in Note 1 as of December 31, 1999 and 1998, and the related  combined
statements of income, venturers' equity and cash flows for each of the two years
in the period ended  December  31,  1999.  These  financial  statements  are the
responsibility  of the joint  ventures'  management.  Our  responsibility  is to
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of the joint ventures  identified
in Note 1 as of December 31, 1999 and 1998, and the results of their  operations
and their cash flows for each of the two years in the period ended  December 31,
1999, in conformity with generally accepted accounting principles.

              Notes to Combined Financial Statements of Significant
                          Construction Joint Ventures
                 For the Years Ended December 31, 1999 and 1998


[1]  Basis of Combination

Perini Corporation (the "Company"),  in the normal conduct of its business,  has
entered into  partnership  arrangements,  referred to as "joint  ventures",  for
certain construction  projects in order to share risk, working capital,  bonding
and  other  financial  requirements  and,  in some  instances,  to  obtain  more
extensive  knowledge  of a new  local  construction  market  or  certain  unique
construction  expertise  required.  Each of the joint  venture  participants  is
usually committed to supply a predetermined  percentage of capital, as required,
and to share in a predetermined percentage of the income or loss of the project.
These joint  ventures  are  temporary  in nature,  generally  from three to five
years,  since they are formed to bid on a specific project,  execute the work if
awarded  the  contract,  and are  liquidated  at the end of the  project.  While
control over the actual construction work performed is normally delegated to the
designated  joint  venture  sponsor,  usually the  partner  with a 50% or higher
percentage interest in the project,  the overall management of the joint venture
resides with a Management  Committee that requires unanimous approval of certain
key  operational  and financial  matters such as the amount of the original bid,
ability to borrow  funds,  incur  debt,  guarantees  and lease  commitments  and
investment policy regarding venture funds. In addition, the Management Committee
requires  unanimous  approval over terms of sale of venture  assets,  settlement
guidelines  related to  contract  claims and any  transaction  between the joint
venture and any of its partners.

In  accordance  with Rule 3-09 of  Regulation  S-X,  the Company  has  presented
combined  financial  statements  of  construction  joint  ventures  rather  than
separate  financial  statements  for each joint  venture,  because  the  Company
believes  that  reporting the financial  results of any one  construction  joint
venture by itself would not be  significant to users and could be detrimental to
the Company when negotiating  unapproved  contract change orders and claims with
the owner of the  project or could  unfairly  assist  competitors  when  bidding
against  the  Company  on  similar  contracts  in  the  future.   The  following
construction  joint  ventures have been combined in the  accompanying  financial
statements:

[2]  Significant Accounting Policies

[a]  Long-Term Contracts

Profits from construction  joint venture  contracts are generally  recognized by
applying the  percentages  of  completion  for each year to the total  estimated
profits for the  contracts.  The  percentages  of completion  are  determined by
relating the actual cost of the work performed to date to the current  estimated
total  cost  of the  respective  contracts.  When  the  estimate  on a  contract
indicates  a loss,  the  ventures'  policy is to record  the  entire  loss.  The
cumulative  effect of revisions in estimates of total cost or revenue during the
course of the work is reflected in the accounting period in which the facts that
caused the revision become known.  An amount equal to the costs  attributable to
unapproved change orders and

claims is included in the total estimated  revenue when realization is probable.
Profit  from  unapproved  change  orders and claims is recorded in the year such
amounts are resolved.

In  accordance  with normal  practice in the  construction  industry,  the joint
ventures  include in current assets and current  liabilities  amounts related to
construction  contracts  realizable  and payable  over a period in excess of one
year.  Unbilled  work  represents  the  excess of  contract  costs  and  profits
recognized  to date on the  percentage  of  completion  accounting  method  over
billings to date on certain contracts.  Deferred contract revenue represents the
excess  of  billings  to date  over the  amount of  contract  costs and  profits
recognized  to date on the  percentage of  completion  accounting  method on the
remaining contracts.

[b]  Income Taxes

The joint  ventures  have not  recorded  any  provision  for income taxes in the
accompanying   combined  financial   statements  as  such  liabilities  are  the
responsibility of the joint venture partners.

[c]  Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent assets and liabilities as of the date of the financial statements and
the reported amounts of revenues and expenses during the reporting  period.  The
most significant  estimates with regard to the accompanying  combined  financial
statements  relate to the estimating of final  construction  contract  profit in
accordance  with  accounting  for  long-term   contracts  (see  Note  2[a])  and
estimating  potential  liabilities in conjunction  with certain  commitments and
contingencies,  as  discussed  in Note  4.  Actual  results  could  differ  from
management's estimates and assumptions.

[d]  Fair Value of Financial Instruments

The joint ventures'  financial  instruments  consist  primarily of cash and cash
equivalents,  contract accounts  receivable and accounts  payable.  The carrying
amount  of these  financial  instruments  approximates  fair  value due to their
short-term nature.

[e]  Cash and Cash Equivalents

Cash equivalents  include  short-term,  highly liquid  investments with original
maturities of three months or less.

[3]  Cash Management

The joint  ventures  regularly  invest  excess cash in highly  liquid,  interest
bearing investments. These temporary investments are converted to cash on an "as
needed"  basis to fund  obligations  as they  become  due.  The  amount  of cash
overdraft  represents  the  amount of  checks  outstanding  which  have not been
presented for payment as of December 31, 1999 and 1998.

[4]  Contingencies and Commitments

The joint ventures have noncancellable  office and equipment leases with varying
expiration dates through July 31, 2005. The following is a schedule, by year, of
future minimum  rental  payments  required under all operating  leases that have
remaining noncancellable lease terms as of December 31, 1999:

                                  =================

For the years  ended  December  31,  1999 and 1998,  rent  expense  relating  to
noncancellable   operating   leases   amounted  to  $1,764,182  and  $1,261,350,
respectively, which is included in contract costs.

Contingent  liabilities  include  liability of contractors  for  performance and
completion of the joint venture construction  contracts.  In addition, the joint
ventures are involved in arbitration and alternative  dispute resolution ("ADR")
proceedings.  In the opinion of management of the various  joint  ventures,  the
resolution of these  proceedings  will not have a material effect on the results
of operations or financial  condition as reported in the  accompanying  combined
financial statements.

[5]  Related Party Transactions

Certain joint  ventures  periodically  make temporary cash advances to the joint
venture  participants.  At December 31, 1999,  the amount of such temporary cash

[b]  Other Joint Venturers

Included in the combined  joint  ventures'  cost of  operations  are charges for
labor and certain  other job material  costs that were incurred with the various
related parties.

[6]  Employee Benefit Plans

The combined  construction joint ventures  contribute to various  multi-employer
union  retirement plans under collective  bargaining  agreements,  which provide
retirement   benefits  for  substantially  all  of  its  union  employees.   The
Multi-employer  Pension Plan  Amendments  Act of 1980 defines  certain  employer
obligations under multi-employer  plans.  Information regarding union retirement
plans are not  available  from plan  administrators  to enable  the  Company  to
determine its share of unfunded vested liabilities.

Supervisory   personnel  are  generally   covered  under  the  sponsoring  joint
venturer's plan.
