USACE Construction Bonds

The U.S. Army Corps of Engineers is the largest federal construction procurement authority. Annual USACE construction spending runs approximately $20 billion across military construction (MILCON), civil works, environmental restoration, and interagency and international support programs. The Corps operates through nine regional divisions and 43 district offices, each of which functions as an independent contracting authority.

What USACE construction contracting is

USACE construction procurement follows the Federal Acquisition Regulation (FAR), supplemented by the Defense Federal Acquisition Regulation Supplement (DFARS) and the Engineering Federal Acquisition Regulation Supplement (EFARS). The Corps uses a variety of contract vehicles:

• Fixed-price construction contracts for defined-scope work such as new building construction or specific infrastructure projects.
• IDIQ (Indefinite Delivery / Indefinite Quantity) contracts with task orders for recurring or geographically dispersed work — common for airfield maintenance, environmental restoration, and multi-year facility programs.
• Design-build contracts under FAR 36.3 two-phase selection for large complex construction where the government seeks a single point of accountability.
• MATOC (Multiple Award Task Order Contracts) with pools of prequalified contractors competing for individual task orders.

Each vehicle triggers bond requirements at the prime contract level and, for IDIQ and MATOC vehicles, at the individual task order level once the task order exceeds the $150,000 Miller Act threshold.

MILCON, civil works, and environmental restoration

Military Construction (MILCON). Facilities work on active military installations for the Army, Air Force, Navy, and Marine Corps. Includes new barracks, headquarters buildings, hangars, maintenance facilities, medical facilities, family housing, training ranges, and utility infrastructure. Individual MILCON projects commonly range from $5 million to $500 million.

Civil Works. Water resources infrastructure — navigation channels, flood risk management (dams and levees), hydroelectric facilities, ecosystem restoration, and coastal storm damage reduction. The Corps is the largest federal owner of dam and levee infrastructure. Civil works contracts routinely exceed $100 million and can reach several billion for major projects such as the Louisiana coastal restoration program and the Illinois Waterway modernization.

Environmental Restoration (FUDS, MMRP, and IRP). Cleanup of former defense sites, munitions response, and installation restoration. Contracts run from a few hundred thousand for site investigations to hundreds of millions for complex remediation. Bonding these accounts requires attention to the environmental risk profile — many carriers decline this class outright.

Framework note: USACE environmental restoration contractors need Miller Act performance and payment bonds securing their construction contract with the Corps — which is what we write. That is a distinct bond from the underlying financial responsibility obligation that the responsible party (or its successor) owes to EPA under CERCLA, or to the state under a corrective action order under RCRA. Those RCRA and Superfund financial responsibility instruments are a separate class governed by 40 CFR Part 264, Subpart H (RCRA) and by CERCLA § 107(k)(2). We write those through our sister site ReclamationBonds.com.

Interagency and International Support. USACE performs work for other federal agencies (VA, DHS, State, EPA, DOE) and for allied governments under various support agreements. These carry the same Miller Act framework as direct USACE work.

Miller Act framework on USACE contracts

Every USACE prime construction contract exceeding $150,000 requires performance and payment bonds under the Miller Act (40 U.S.C. §§ 3131-3134). The specific requirements:

• Performance bond at 100% of the contract price, executed on Standard Form 25 (SF 25), guaranteeing completion of the contract in accordance with its terms.
• Payment bond at 100% of the contract price, executed on Standard Form 25A (SF 25A), for the protection of persons furnishing labor and materials on the project.
• Bid bond at 20% of the bid amount or $3 million, whichever is less, executed on Standard Form 24 (SF 24) when required by the solicitation. FAR 28.101 makes the bid bond discretionary for the contracting officer on many procurements, but it is universally required on major USACE construction.

Both performance and payment bond sureties must be listed on Treasury Department Circular 570 and must have an underwriting limit that equals or exceeds the individual bond amount. On very large USACE projects (typically over $250 million), co-surety or reinsurance arrangements are used to meet this requirement.

Federal bond forms — SF 24, SF 25, SF 25A

The three principal federal construction bond forms and their essential features:

Form	Purpose	Standard penal sum
SF 24	Bid guarantee	20% of bid or $3 million
SF 25	Performance	100% of contract
SF 25A	Payment	100% of contract

The forms are prescribed by FAR 53.228 and cannot be materially altered by contracting officers or by sureties. Manuscript language addressing specific project features (typically stipulated in a rider) is permitted where it does not conflict with the standard form.

Common project types and typical bond sizes

Typical USACE construction bond sizes by project category:

Project category	Typical contract range
MILCON facility (barracks, admin, maintenance)	$5M – $75M
MILCON major facility (medical, headquarters)	$75M – $500M
Airfield pavement (runways, taxiways, aprons)	$10M – $100M
Civil works — flood risk management (levees, floodwalls)	$25M – $500M
Civil works — navigation (dredging, lock construction)	$10M – $1B+
Civil works — hydroelectric and dam	$50M – $500M
Environmental restoration (FUDS, IRP)	$500K – $200M
Interagency support (VA, DHS facilities)	$1M – $100M

Dredging, marine, and hydraulic construction

USACE navigation and coastal work involves substantial dredging, marine construction, and hydraulic engineering — categories that require specialized surety underwriting because of the equipment concentration, weather sensitivity, and technical failure modes involved.

Dredging in particular is a specialty class. A handful of large dredging contractors (Great Lakes Dredge & Dock, Weeks Marine, Manson, Norfolk Dredging, Cashman) dominate the market. Bonding these accounts requires understanding of hopper vs. cutter suction operations, dredge equipment values, disposal permit compliance, and the seasonal windows that constrain project scheduling in northern latitudes.

Marine construction — piers, wharves, bulkheads, cofferdams, and lock structures — carries similar specialty considerations. We write these classes with attention to the specific project-execution plan, the contractor's marine equipment fleet, and the marine subcontractor bench.

Underwriting the USACE contractor

USACE underwriting weights the factors common to all federal construction bonding, with specific attention to:

• Prior federal completed work. Completed USACE contracts of comparable size and scope. Prior task orders under IDIQ or MATOC vehicles.
• Financial strength. Working capital, net worth, backlog-to-capacity ratios. The Constantin working capital test: current assets less current liabilities should support approximately one-tenth of aggregate bonded backlog for prudent programs.
• Bond form language and project scope. The specific SF 25 rider language, the technical scope of work, and any manuscripted performance obligations.
• Environmental exposure. On restoration and cleanup projects, the risk profile of the contamination, the response actions specified, and the contractor's environmental insurance coverage.
• Marine, hydraulic, or specialty exposure. Where the work involves specialty operations, the contractor's specialty equipment fleet, subcontractor bench, and prior similar completed work.
• Subcontractor default management. The prime's practices for prequalifying and bonding key subcontractors (subcontractor default insurance or subcontractor bonds).
