We recommend that the Architect of the Capitol (AOC) review the contracting manual to determine whether the language restricting access to Independent Government Estimate (IGE) information solely to AOC personnel who require knowledge of the estimate is appropriate. If the AOC determines the language is appropriate as written, it should enforce this requirement. If the AOC determines that it is appropriate to use non-AOC personnel in the IGE process, it should update its contracting manual to reflect that decision and implement appropriate safeguards to ensure the process remains both independent and confidential.
