We recommend the Architect of the Capitol review the insufficiently supported questioned costs identified within the Russell Stone Exterior Envelope Repair and Restoration ($66,449) and the Thurgood Marshall Federal Judiciary Building Administrative Office Space Realignments ($18,968) 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.
