Review the insufficient supported questioned costs of $478,557 ($481,273 - $2,716) identified within the Cannon House Office Building Renewal ($367,315) and R-Tunnel ($111,242) projects to determine if the costs are supported and allowable; for any of the costs deemed unsupported and/or unallowable, recover the costs to the extent legally and administratively possible; as applicable, recover any additional amounts resulting from the application of items such as overhead and profits to the unallowable costs.
