A written justification must be submitted immediately after Plans and Specifications are developed.
Proposals are subject to review similar to that for contracts.
The FAA will apply the same requirements in review of plans and specifications as in conducting construction inspections. The sponsor must keep records on costs of materials, hourly operation of equipment, payrolls, and all other costs to avoid disallowance of costs that cannot be verified in audit. FAA References Order 5100. 38A FAA Coordination Coordinate with appropriate State Airport Engineer from the Airports Division Definition - Construction performed by the sponsor's own personnel. Sponsor's proposal shall be submitted in writing for FAA approval.
