**CERTIFICATION
      BY PRINCIPAL FINANCIAL OFFICER**


**UNDER
      SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002**




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.
 
      The Registrant’s other certifying officer(s) 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




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.
