The FAA is conducting a market survey for Environmental Architecture and Engineering services at the Mike Monroney Aeronautical Center in Oklahoma. The work involves a wide range of environmental consulting and remediation activities. The FAA anticipates awarding a single-award, five-year Indefinite Delivery/Indefinite Quantity contract with Time and Materials pricing. Responses will inform acquisition planning and set-aside decisions for small business categories. This is for planning purposes only and is not a request for proposal.
