**CERTIFICATION
      BY PRINCIPAL FINANCIAL OFFICER**





I,
      Timothy C. Dec, certify that:




1.
 
      I have reviewed this Quarterly Report on Form 10-Q of Fortress International
      Group, Inc. (the “Registrant”);





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.
 
      I am responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) 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)   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





(c)   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





5.
 
      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 person 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.
