1.     We note that you have adopted SFAS 123(R) as of January 1, 2006 and  that
you  recorded  an expense of  $640,000  relating  to the  exercising  of 287,832
options by six  individuals  during the year ended  December  31,  2006.  Please
explain to us your  accounting  for these  options that resulted in this expense
and please cite the specific accounting  literature that you relied on to record
the expense as a result of these individuals  exercising their options.  We also
note that additional  stock  compensation  was recognized as a result of vesting
during the period.

Response:

Year ended December 31, 2006

In  reviewing  the  comment by the  Commission,  and the  applicable  accounting
literature,  we have  determined  that the Company has  incorrectly  recorded an
expense in its 2006  consolidated  financial  statements  when  options that had
vested prior to the adoption of SFAS 123(R) were exercised.

On  January  1,  2006,  the  Company  adopted  SFAS  123(R)  using the  modified
prospective method.

At various times during 2006, an aggregate of 287,832 fully vested  options were
exercised.  The Company incorrectly  recorded expense for the intrinsic value of
these  exercised  options equal to the  difference  between the option  exercise
price and the quoted market value for the Company's  common stock on each of the
exercise dates.

As  a  result,   the  Company   incorrectly   reported   selling,   general  and
administrative  expenses  totaling $636,000 in connection with the exercising of
stock options during the year ended December 31, 2006.  This error had no effect
on reported revenue, gross profit, cash position, or total stockholders' equity,
but reduced reported net earnings for 2006 by $343,000, or $0.06 per share-basic
and diluted.

The Company disclosed expenses related to the exercise of stock options,  net of
taxes,  in  Management's  Discussion  and  Analysis of Financial  Condition  and
Results of Operations  ("MD&A") in its Annual Report on Form 10-K, as well as in
an earnings press release. In each of these documents, net earnings and earnings
per share  were  presented  both with and  without  the  effect of stock  option
expense.  Total  expenses  recorded for the exercise of stock  options were also
disclosed in the footnotes to the consolidated financial statements.

For the year ended  December  31,  2006,  the Company  reported  net earnings of
$2,765,000,  or $0.49 per share-basic and $0.48 per  share-diluted.  The Company
also  disclosed in the MD&A in its Annual  Report on Form 10-K that stock option
expenses recorded during the period reduced net income by $374,000, or $0.07 per
share-basic and diluted.  This reduction of $374,000  correctly included $29,000
related to the vesting of stock  options under SFAS 123(R) and $2,000 of payroll
tax expense related to previously  vested stock options  exercised  during 2006.
The $374,000 reduction incorrectly included compensation expenses related to the
exercise  of stock  options  totaling $ 343,000,  or $0.06 per  share-basic  and
diluted.  After reversing this expense, net income will increase from $2,765,000
to $3,108,000.

The Company reported fourth quarter 2006 earnings by issuing a press release and
a Current  Report on Form 8-K.  This press  release  began with a discussion  of
fourth quarter 2006 results and then described expenses related to stock options
and a reversal of an allowance. A similar discussion of the results for the year
ended December 31, 2006 followed.

Nine months ended September 30, 2007

As previously stated, the Company has incorrectly recognized expenses when stock
options were exercised  during 2006. This error continued in the Company's three
quarterly filings during 2007.

At various  times during the nine months ended  September 30, 2007, an aggregate
of 140,416 fully vested options were exercised.

As  a  result,   the  Company   incorrectly   reported   selling,   general  and
administrative  expenses  totaling $662,000 in connection with the exercising of
stock  options  during the nine months ended  September  30,  2007.  This had no
effect on reported revenue,  gross profit, cash position, or total stockholders'
equity,  but reduced  reported net earnings for the nine months ended  September
30, 2007 by $357,000, or $0.05 per share-basic and $0.06 per share-diluted.

As it had done in 2006, the Company  disclosed  expenses related to the exercise
of stock options,  net of taxes, in the MD&A in each of its three 2007 Quarterly
Reports on Form 10-Q, as well as in earnings  press  releases.  In each of these
documents,  earnings and earnings per share were presented both with and without
the effect of stock option expense.  Total expenses recorded for the exercise of
stock options were also disclosed in the footnotes to the consolidated financial
statements.

Proposed Correction

The Company does not believe that a restatement is needed,  since 2006 earnings,
as well as earnings for each of the first three quarters of 2007, were disclosed
both with the stock option expenses and without the stock option expenses in the
Annual Report on Form 10-K, in each Quarterly  Report on Form 10-Q for 2007, and
in earnings press releases and related Current Reports on Form 8-K. Although the
corrected  amounts  reflect  a  change  to  the  Company's  previously  reported
earnings,  the corrected earnings amounts are not materially  different from the
amounts  disclosed as earnings without the effect of stock option expenses.  The
investor  public was made aware of these  expenses,  knew the  results  with and
without  the  expenses,  and had  adequate  information  to  make an  investment
decision.  We believe restatement of the prior periods would not provide any new
information.

Based on the above, the Company proposes to report the corrections of the errors
prospectively  in its Annual Report on Form 10-K for the year ended December 31,
2007. We also propose to adjust the 2006 and 2007 unaudited  selected  quarterly
information  included in the footnotes to the consolidated  financial statements
in the same  filing.  We also  propose  to issue a press  release  and a Current
Report on Form 8-K describing the reporting error and the corrected earnings for
2006 and the first three quarters of 2007.

The Company hereby acknowledges that:

   o   the  Company  is  responsible  for  the  adequacy  and  accuracy  of  the
       disclosure in the filings;

   o   staff  comments or changes to disclosure in response to staff comments in
       the filings  reviewed by the staff do not foreclose the  Commission  from
       taking any action with respect to the filing; and

   o   the Company may not assert staff  comments as a defense in any proceeding
       initiated by the  Commission  or any person under the federal  securities
       laws of the United States.

If any  member  of the  Commission's  Staff  has  any  questions  regarding  the
foregoing,  or  desires  further  information  or  clarification  in  connection
therewith,  please contact the  undersigned at 718-340-1444 or James Oliviero at
718-340-1409.

Very truly yours,


KSW, INC.
