The Government is contemplating a Multiple Award Construction Contract for General Construction Services (MACC) that will accomplish a broad range of sustainment, maintenance, repair, alteration/renovation, and minor construction projects affecting real property facilities at Tinker Air Force Base, Oklahoma. Work performed will be complex in nature, require multiple construction trades, and may require engineering design performed by credentialed professionals. Anticipated project execution methods will fall into one of three categories: Design-Build, Construction with Limited Design or Construction Only.

This indefinite delivery, indefinite quantity contract will be used to acquire construction work at Tinker AFB, OK as awarded on individual orders. Except as this contract may otherwise provide, if the Government’s requirements do not result in orders in the quantities described as "estimated" or "maximum" in the Schedule, that fact shall not constitute the basis for an equitable price adjustment.

Disclaimer Regarding Construction Project Data

The historical construction project data and projected future construction projects are provided to offerors solely for informational and estimation purposes. This data does not constitute a commitment, implied or otherwise, and shall not bind or obligate the Government to procure, award, or fund any future construction projects based on this information. Furthermore, the Government’s decision not to procure, award, or fund projects described herein shall not entitle offerors to an equitable adjustment, claim for reimbursement, or any other form of compensation.

The Government is contemplating awarding two contractor pools as follows:

• Small Business Pool: Task Orders under $10M


• Full and Open Pool: Task Orders $10M or above

Small Businesses will have the opportunity to compete in both the Small Business pool and the Full and Open pool for award of a MACC.

The Government anticipates awarding one 5-year contract with one 5-year option period.

Historical project magnitudes and anticipated project magnitudes are attached for review. Specific Independent Government Estimates (IGE) or contract award amounts will not be provided. Anticipated project magnitudes are not guaranteed and are subject to change at any time. Additionally, anticipated project magnitudes should not be used to guarantee award of task orders for offerors awarded a MACC in either pool.
