What contract surety is
Contract surety bonds secure the performance of construction contracts. The owner of a project, public or private, requires the contractor to furnish bonds so that if the contractor fails, a solvent third party stands behind completion of the work and payment of the people who supplied labor and material to it. On public work the requirement is statutory; on private work it is a matter of the owner's credit judgment, and increasingly of its lenders' requirements.
The economic function is prequalification. A surety that issues a performance bond has examined the contractor's financial statements, its work in progress, its banking relationships, its people, and its history of finishing what it starts. The bond is a credit opinion enforced with the surety's balance sheet. That is why owners rely on it, and why obtaining surety credit is a milestone in a contractor's development, not a purchasing transaction.
The desk manages bonded work programs the way a lender manages a credit facility: single and aggregate limits set from the file, reviewed as financial statements arrive, and grown deliberately as the contractor's capital and capacity grow. We place emerging contractors through markets built for that stage, including programs supported by the U.S. Small Business Administration's Surety Bond Guarantee program, and established contractors into standard and preferred markets through Janus Assurance Re and its carrier panel.
Bid Bonds
The bid bond accompanies a proposal and guarantees two things: that the bidder will enter into the contract at its bid price if awarded, and that it will furnish the required performance and payment bonds. The penal sum is a percentage of the bid, commonly five to twenty percent depending on the obligee. If the bidder refuses the award, the obligee recovers the difference between that bid and the next responsive bid, up to the penal sum.
Bid bonds cost the contractor little or nothing, but they are not free of consequence. A surety issues a bid bond only where it is prepared to write the final bonds, so bid bond support is the first real test of the surety relationship. The desk turns routine bid requests same day against an established work program.
Performance Bonds
The performance bond guarantees that the contract will be completed according to its terms. On default, the surety's options under the standard forms include financing the principal to completion, taking over and completing with another contractor, tendering a new contractor to the obligee, or paying the obligee's cost to complete, in each case up to the penal sum, which is customarily one hundred percent of the contract price.
The obligation follows the contract, including its warranties, and the instrument must be read together with the contract documents it incorporates. The desk reviews bond forms before execution, flags onerous or nonstandard language, and places obligations on federal standard forms, AIA A312, ConsensusDocs, and obligee-drafted manuscript forms.
Payment Bonds
The payment bond guarantees payment of subcontractors, laborers, and material suppliers on the project. Its importance on public work cannot be overstated: mechanic's liens do not attach to public property, so the payment bond is the only security available to the people who actually build the project. Claim rights, notice requirements, and limitation periods are fixed by statute on public work and by the bond form on private work, and they are unforgiving of missed deadlines.
The desk places payment bonds together with performance bonds as the statutory pair, and counsels principals on the notice and certification obligations that follow.
Maintenance Bonds
A maintenance bond guarantees the work against defects in workmanship and materials for a stated period after completion, commonly one or two years. Short maintenance periods incidental to the contract are frequently included within the performance obligation; longer or standalone maintenance obligations are underwritten separately, because a guarantee against latent defects five years out is a different risk than a guarantee of completion.
Subdivision & Site Improvement Bonds
Municipalities condition plat approval on security that the developer will complete public improvements: streets, curbs, sidewalks, drainage, water, and sewer. The subdivision bond runs in favor of the municipality, and its distinctive risk is that the principal is a developer whose ability to finish improvements depends on lot sales and project financing rather than on progress payments from the obligee. Underwriting is accordingly closer to real estate credit than to contract analysis: project budgets, takedown schedules, loan commitments, and the developer's liquidity. The desk places subdivision, site improvement, and completion obligations for developers and builders nationwide.
Miller Act & Federal Work
On federal construction contracts exceeding one hundred thousand dollars, the Miller Act, 40 U.S.C. §§ 3131 through 3134, requires a performance bond and a payment bond, each issued by a surety satisfactory to the contracting officer, in practice a corporate surety listed by the U.S. Department of the Treasury on Circular 570. Every state has enacted its own Little Miller Act imposing analogous requirements on state and municipal work, with thresholds, percentages, and claim procedures that vary by jurisdiction.
The desk places federal obligations exclusively through Treasury-listed carriers with underwriting limitations adequate to the contract, and maintains the jurisdiction-by-jurisdiction detail that Little Miller Act compliance requires.
The Contractor's Guide to Surety Bonds
Written by C. Constantin Poindexter, CPCU, JD, MA, AFSB, ASLI, ARe, AINS, AIS, CPLP, and published by NewSouth Books, the guide walks contractors through surety credit the way an underwriter actually reads it: financial statement presentation, work programs, indemnity, and what to do when a project goes sideways. It is the reference we hand principals before their first bonded job.
How a work program is underwritten
Contract underwriting rests on the three Cs. Capital: CPA-prepared financial statements, analyzed for working capital, equity, and the quality of both; percentage of completion statements carry more weight than compilations. Capacity: the work in progress schedule read against the largest job completed, the present backlog, and the people and systems that will execute it. Character: the record of finishing hard jobs, the candor of the file, and the continuity plan behind the principals. From these the underwriter sets a single job limit and an aggregate program, and the desk's task thereafter is to grow both as the contractor grows, and to defend them when a year goes badly.
Every program is supported by a general indemnity agreement executed by the operating entity and its principals. The desk explains the instrument before signature, because an indemnity agreement misunderstood at signing becomes a grievance at the first loss, and a program built on grievance does not last.
Frequently asked questions
What do the three contract bonds actually guarantee?
The bid bond guarantees the bidder will enter the contract and post final bonds if awarded. The performance bond guarantees completion of the work according to the contract documents. The payment bond guarantees payment of subcontractors, laborers, and material suppliers, which on public work substitutes for the mechanic's lien rights unavailable against government property.
What does a performance bond cost?
Contract bond premium is computed on the contract price under a rate filed by the carrier, and the effective rate depends on the contractor's financial strength, experience, and the character of the work. Terms are quoted subject to credit and underwriting after review of the contractor's file.
What is the Miller Act and does it apply to my project?
The Miller Act, 40 U.S.C. sections 3131 through 3134, requires performance and payment bonds on federal construction contracts exceeding one hundred thousand dollars. Every state has enacted an analogous Little Miller Act for state and municipal work, with thresholds and details that vary by jurisdiction.
How is a bonding line or work program established?
The surety evaluates capital, capacity, and character: CPA-prepared financial statements, work in progress and completed contract schedules, bank and credit relationships, resumes of key personnel, and the continuity plan. From that file the underwriter sets single and aggregate limits, which grow with the contractor's balance sheet and performance record.
Can a new or smaller contractor qualify for bonds?
Yes. Emerging contractors are placed through markets built for that purpose, including programs supported by the U.S. Small Business Administration's Surety Bond Guarantee program, and grow into standard markets as their financial statements mature. The desk manages that progression deliberately.
What happens if a claim is made on a contract bond?
The surety investigates, and if the principal is in default, performs through completion arrangements or payment up to the penal sum. Every dollar the surety pays is recoverable from the principal and its indemnitors under the general indemnity agreement, which is why default is a credit event, not an insurance event.
