GSA Design-Build Bonds

The General Services Administration is the federal government's principal owner and operator of federal buildings, land ports of entry, and courthouses. GSA construction spending — concentrated in the Public Buildings Service — averages $2 billion to $4 billion annually, with individual major projects often exceeding $200 million.

GSA construction procurement overview

GSA construction is procured under the Federal Acquisition Regulation (FAR) and the General Services Administration Acquisition Regulation (GSAR). The GSA operates through eleven regional offices, each managing construction procurement within its geographic region.

The two principal delivery models:

• Design-build. The prime contractor is responsible for both design and construction. Most major GSA construction ($20 million and up) is delivered this way. Selection follows FAR 36.3 two-phase source selection.
• Design-bid-build. Traditional model with government-furnished design followed by competitive construction bidding. Still used on smaller projects and where owner design control is prioritized.

The Public Buildings Service portfolio

The Public Buildings Service (PBS) is the GSA operating body responsible for federal building acquisition, construction, and management. PBS owns approximately 1,600 federal buildings totaling roughly 200 million square feet.

The PBS construction portfolio breaks into four principal categories:

• Federal courthouses. New construction and major renovation for U.S. District Courts, Courts of Appeals, and specialty federal courts. Individual courthouse projects range from $75 million for smaller district courthouses to over $600 million for major appellate and district facilities.
• Land ports of entry. Border crossing facilities for CBP operations at the northern and southern land borders. Individual land port projects range from $30 million to $500 million.
• Federal buildings. General-purpose federal office buildings, agency headquarters, and specialty facilities (data centers, laboratories). Wide range from $10 million to $300 million.
• Historic preservation. Restoration and modernization of federally-owned historic buildings, including many National Historic Landmark structures.

FAR 36.3 Two-Phase Design-Build Selection

Major GSA design-build procurement uses the two-phase selection procedure at FAR 36.3:

1. Phase One: Qualifications-based competition. Offerors submit qualifications packages (technical approach, past performance, key personnel). The government evaluates and shortlists three to five firms for Phase Two.
2. Phase Two: Price and design competition. Shortlisted firms submit detailed technical proposals with schematic design and firm pricing. The government evaluates and awards to the offeror providing best value.

Bid bonds (SF 24) are typically required on Phase Two submissions at 20% of the price proposal. The bid bond is at risk if the successful offeror declines to enter into the contract or fails to furnish the required performance and payment bonds.

Bridging documents and their bonding implications

GSA design-build solicitations are typically accompanied by "bridging documents" — a partial design (typically 15% to 35% complete) prepared by a government-hired bridging architect that establishes the design intent. The bridging documents constrain the design-build contractor's design flexibility while leaving detailed design and construction to the contractor's responsibility.

From a bonding perspective, bridging documents create a distinctive risk profile:

• The government owns the design intent embodied in the bridging documents. Errors in the bridging documents can create ambiguity about responsibility for consequential design changes.
• The design-build contractor's design responsibility begins where the bridging documents end. The boundary is not always crisply defined.
• Change order disputes frequently arise from bridging document ambiguity. Experienced federal design-build primes budget contingency for this specifically.

Sureties writing GSA design-build bonds price the design responsibility separately from the construction responsibility, and pay particular attention to the design team's professional liability coverage and the specific design-build contract terms allocating design risk.

Federal courthouses, land ports, and federal buildings

The three principal PBS construction categories have distinctive bonding features:

Federal courthouses. High-security, high-symbolism structures with substantial owner design involvement. Design-build with heavy bridging documents. Historic project cost ranges $75 million to $600 million. Bond exposure is substantial and often requires co-surety or reinsurance arrangements for the largest packages. The Administrative Office of the U.S. Courts (AOUSC) participates alongside GSA on many courthouse projects.

Land ports of entry. High-security customs and immigration facilities at land border crossings. Northern border (Canada) and southern border (Mexico) projects. Historic project cost ranges $30 million to $500 million. Bond exposure often includes specialty security-technology components (X-ray inspection, biometric systems).

Federal buildings. Broader category including agency headquarters, laboratories, data centers, and general-purpose office buildings. Wide range of bond exposures depending on program.

Miller Act on GSA design-build contracts

All GSA design-build prime construction contracts exceeding $150,000 require performance and payment bonds under the Miller Act. Standard forms SF 25 (performance) and SF 25A (payment) at 100% of contract amount. Executed by carriers listed on Treasury Circular 570.

Design-build creates one distinctive Miller Act issue: the design work is generally excluded from Miller Act payment bond protection because the Act applies to "labor and material" furnished on the construction. Design professionals (architects, engineers) engaged as design subconsultants are typically outside the payment bond's coverage. Design-build prime contractors and sureties account for this through separate professional liability arrangements.

Underwriting the GSA design-build contractor

GSA design-build underwriting weights the standard federal construction factors plus considerations specific to the design-build delivery model:

• Prior GSA design-build completed work. Prior GSA or comparable federal design-build projects. Prior federal courthouse or land port experience for those specific project types.
• Design-build team composition. The specific design partner or in-house design capacity, the design team's professional liability coverage limits, and the design partner's track record on federal design-build.
• Financial strength. Working capital, net worth, and backlog capacity — with design-build bond exposures often larger than the prime's conventional work size.
• Specialty subcontractor bench. Courthouse-specific security systems, land port-specific inspection technology, and other agency-specific specialties.
• Bridging document analysis. The contractor's practices for reviewing bridging documents, identifying gaps and inconsistencies, and structuring change order administration.
• Bond program capacity. Major GSA courthouse and land port work commonly requires co-surety or reinsurance arrangements. We coordinate program capacity at submission.

How to apply

Email underwriting@suretyone.com or call (800) 373-2804. Include the specific GSA solicitation, the PBS region, the design-build team composition, and the standard financial documentation package. For phase-one qualifications packages that do not yet require bond commitments, we can discuss capacity availability and structure bond letters of support for Phase Two submissions.
