                           RULE 13A-14(A)

I, Richard W. Lucas, certify that:

    1. I have reviewed this quarterly report on Form 10-Q of KSW, Inc.;

    2. Based on my knowledge, this report does  not contain any untrue statement
       of a material fact or omit to state a material fact necessary to make the
       statements  made,  in  light  of  the  circumstances  under  which   such
       statements were made, not misleading  with respect to the period  covered
       by this report;

    3. Based  on  my  knowledge,  the  financial statements, and other financial
       information  included  in this  report,  fairly present  in  all material
       respects the financial condition, results of operations and cash flows of
       the registrant as of, and for, the periods presented in this report;

    4. The  registrant's  other  certifying  officer  and  I are responsible for
       establishing  and  maintaining  disclosure  controls  and  procedures (as
       defined in  Exchange Act  Rules   13a-15(e) and  15d-15(e)) and  internal
       control over financial  reporting (as defined  in Exchange Act  Rules 13a
       -15(f) and 15d-15(f)), for the registrant and have:

            (a) Designed such disclosure controls and procedures, or caused such
            disclosure  controls  and  procedures  to  be  designed  under   our
            supervision, to  ensure that  material information  relating to  the
            registrant, including its  consolidated subsidiaries, is  made known
            to  us  by others  within  those entities,  particularly  during the
            period in which this report is being prepared;

            (b)  Designed such  internal  control  over financial  reporting, or
            caused such internal control over financial reporting to be designed
            under our supervision, to provide reasonable assurance regarding the
            reliability of financial reporting and the preparation of  financial
            statements  for  external  purposes  in  accordance  with  generally
            accepted accounting principles;

            (c)  Evaluated  the  effectiveness  of  the  registrant's disclosure
            controls and procedures and presented in this report our conclusions
            about the effectiveness of  the disclosure controls and  procedures,
            as of the  end of the  period covered by  this report based  on such
            evaluation; and

            (d) Disclosed in this report any change in the registrant's internal
            control   over  financial   reporting  that   occurred  during   the
            registrant's  most recent  fiscal quarter  (the registrant's  fourth
            fiscal quarter in the case of an annual report) that has  materially
            affected,  or  is  reasonably  likely  to  materially  affect,   the
            registrant's internal control over financial reporting; and
<PAGE>

   5.  The registrant's other certifying officer and I have disclosed, based  on
       our most recent evaluation of internal control over financial  reporting,
       to the registrant's auditors and the audit committee of the  registrant's
       board of directors (or persons performing the equivalent functions):

            (a)  All significant  deficiencies and  material weaknesses  in  the
            design or  operation of  internal control  over financial  reporting
            which are  reasonably likely  to adversely  affect the  registrant's
            ability  to   record,  process,   summarize  and   report  financial
            information; and

            (b) Any fraud, whether or not material, that involves management  or
            other  employees who  have a  significant role  in the  registrant's
            internal control over financial reporting.
