  **CERTIFICATION
        BY PRINCIPAL FINANCIAL OFFICER**
 
 I,
        Thomas
        P. Rosato, 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.
