NASA/Johnson Space Center is issuing a Request for Proposal (RFP) for the Johnson Space Center Multiple Award Construction Contract (JMACC), 80JSC026R0008.

The Johnson Space Center (JSC) Multiple Award Construction Contract (JMACC) will be a Multiple Award, Indefinite Delivery,

Indefinite Quantity (IDIQ) contract vehicle for construction, revitalization, recapitalization, and infrastructure improvement projects at Johnson Space Center (JSC) and White Sands Test Facility (WSTF).

• General construction.

• Alteration, modification, and renovation of existing facilities.

• Maintenance and repair of buildings and infrastructure.

• Demolition of structures and facilities.

• Design-build services.

• New construction of buildings, facilities, and real property

NASA will conduct this acquisition as a full and open competition. The North American Industry Classification System (NAICS) code for this acquisition is 236210 and the small business size standard is forty-five million. This competitive acquisition will result in a Multiple Award, Indefinite Delivery Indefinite Quantity (IDIQ) with the ability to issue Firm-Fixed Price (FFP) task orders.
