The U.S. General Services Administration (GSA), Public Buildings Service (PBS), Acquisition Project Delivery – Capital Construction Division, is seeking construction services for the reanimation of the GSA Headquarters Building at 1800 F Street, NW, Washington. 1800F was listed on the National Register of Historic Places in 1986, recognizing its architectural and federal government significance. The project seeks to transform the historic building from a series of incremental renovations into a long-term, adaptable federal asset that will provide the opportunity for two agencies, GSA and the U.S. Office of Personnel Management (OPM), to co-locate and reimagine what is possible in a shared headquarters. The primary objective is to complete the reimagination, enhance building performance, and ensure the space can adapt to future workforce and multi-tenant requirements. This project will set a new standard for a modern, adaptable federal workplace. The project will focus on the renovation of Wings 0 and 3, which remain unrenovated and unoccupied due to their deteriorated condition, tenant improvement renovations in the modernized Wings 1, 2, & 4, building envelope repairs including masonry, windows and roofs, and reactivation of the building courtyards through the addition of raised courtyard plazas and canopy enclosures. The project aims to restore the building to full operational use and preserve the architectural integrity of this landmark historic facility. The project will be delivered via the Construction Manager as Constructor (CMc) delivery method in which GSA contracts with a CMc during the design phase of the project to provide design input and constructability review and establishes a Final Construction Contract option to execute the construction portion of the project. The design phase services shall be performed at a firm-fixed-price. Early construction services for core and shell are also expected to be awarded at a firm-fixed-price at time of initial contract award. The optional construction services for interiors and courtyards will be priced at a Final Construction Contract Price and may be exercised at a firm-fixed-price. Cost Accounting Standards (CAS) are not anticipated to be required for this procurement. This solicitation will be executed pursuant to the Revolutionary FAR Overhaul (RFO) Federal Acquisition Regulation (FAR) 15. A “Best Value” tradeoff will be conducted in accordance with RFO FAR 15.103-1 Tradeoff approach. Pursuant to FAR Clause 52.215-1 (GSA Class Deviation RFO-2025-15) Instructions to Offerors-Competitive Acquisition, the Government intends to evaluate proposals and award contracts without discussions with offerors (except clarifications as described in RFO FAR 15.202, although it reserves the right to open discussions should it be determined to be in its best interests. It is the government’s intention to award a contract to the offeror whose proposal conforms to the RFP requirements and is considered to be the most advantageous to the government, price and technical factors considered. Competitive proposals shall be evaluated and assessed based on the factors specified in this solicitation. For this solicitation, the combined weight of the non-price factors is significantly more important than the Total Evaluated Price. GSA anticipates using a “Paired Proposal Procedure” to satisfy the Project Labor Agreement (PLA) requirements in RFO FAR 22.5. The paired-proposal procedure requires each offeror to submit a PLA proposal, and permits each offeror to also submit a non-PLA proposal for the same scope of work.
