How to bid on Construction Manager as Constructor Services for the GSA Building at 1800F Street NW
What the GSA is buying and why it matters
The General Services Administration (GSA) is seeking a Construction Manager as Constructor (CMc) for the renovation and reactivation of its historic headquarters building at 1800 F Street NW in Washington, DC. This project aims to transform the building into a long-term, adaptable federal asset for GSA and the U.S. Office of Personnel Management (OPM) to co-locate.
The scope of work includes renovating Wings 0 and 3, tenant improvements in Wings 1, 2, and 4, building envelope repairs (masonry, windows, roofs), and courtyard upgrades with raised plazas and canopy enclosures. The goal is to restore the building to full operational use while preserving its architectural integrity. This is a full and open competition with one planned award, and the NAICS size standard is $45 million in average annual receipts.
Key dates and what happens at the deadline
Registration for the mandatory pre-proposal site visit is due by August 6, 2026. The site visit itself is scheduled for August 11, 2026, at 1800 F St NW, Washington, DC. Requests for Information (RFIs) are due by August 18, 2026.
Phase I proposals are due by August 28, 2026, at 11:00 AM ET. The government intends to evaluate proposals and award a contract without discussions, though it reserves the right to open discussions if deemed in its best interest. The combined weight of non-price factors is significantly more important than the Total Evaluated Price.
Who this opportunity suits
This opportunity is suitable for experienced construction firms specializing in commercial and institutional building construction, particularly those with expertise in renovating historic properties. The project uses a Construction Manager as Constructor (CMc) delivery method, meaning the contractor will provide design input and constructability review during the design phase, with an option for the construction portion.
The NAICS code for this acquisition is 236220 (Commercial and Institutional Building Construction), with a small business size standard of $45 million in average annual receipts. Firms capable of handling complex, multi-phase projects with significant historical preservation aspects will find this suitable.
