• Contractors and subcontractors must preserve all regular payrolls and basic records for at least 3 years after the prime contract work is completed, as required by Legal Information Institute .
• The wage determination and Davis-Bacon poster (WH-1321) must be posted at all times in a prominent and accessible place at the site of the work, according to Legal Information Institute .
• If a bidder fails to enter into the contract in accordance with the bid and fails to furnish a bond within 10 days of notice, the check or postal money order is forfeited to the council or commission, or the council or commission recovers the amount of the surety bond, according to Washington State Legislature .
• The public body must release and pay in full the amounts retained during contract performance 60 days after completion of all contract work, reported by Washington State Legislature .

The following table lists the eight core compliance rules drawn from federal and state sources. Each row names the publisher that states the rule and links to the source document. Use this table to verify that your public works contracts cover wage rate payment, wage poster placement, bid bond forfeiture, retainage release timing, bid estimate requirements, dispute resolution procedures, highway construction definition, and partial payment rates.

According to Legal Information Institute , laborers and mechanics must be paid the appropriate wage rate and fringe benefits on the wage determination for the classification of work actually performed. This requirement applies without regard to skill, except as provided in specific regulatory paragraphs. This rule ensures that the wage determination matches the actual work performed on the site.

The Legal Information Institute states that contractors and subcontractors must maintain all regular payrolls and other basic records during the course of the work ( Legal Information Institute ). These records must be preserved for all laborers and mechanics working at the site of the work for a period of at least 3 years after all the work on the prime contract is completed ( Legal Information Institute ). This retention requirement applies to workers otherwise working in construction or development of the project under a development statute ( Legal Information Institute ). For a broader retention checklist, see payroll record retention clocks .

The same source specifies that the contractor or subcontractor must preserve all certified payrolls during the course of the work ( Legal Information Institute ). These certified payrolls must also be kept for a period of 3 years after all the work on the prime contract is completed ( Legal Information Institute ). Additionally, the contractor or subcontractor must preserve contracts, subcontracts, and related documents during the course of the work ( Legal Information Institute ). These documents must be preserved for a period of 3 years after all the work on the prime contract is completed ( Legal Information Institute ).

Regarding wage posting, the Legal Information Institute notes that the wage determination must be posted at all times by the contractor and its subcontractors ( Legal Information Institute ). The wage determination includes any additional classifications and wage rates conformed under paragraph (a)(1)(iii) of the section ( Legal Information Institute ). The Davis-Bacon poster (WH-1321) must also be posted at all times by the contractor and its subcontractors ( Legal Information Institute ). These items must be posted at the site of the work in a prominent and accessible place where it can be easily seen by the workers ( Legal Information Institute ).

Bid bond forfeiture rules vary by jurisdiction. Under RCW 35.23.352, if a bidder fails to enter into the contract in accordance with their bid and furnish a bond within 10 days from the date they are notified they are the successful bidder, the check or postal money order and the amount thereof shall be forfeited to the council or commission, or the council or commission shall recover the amount of the surety bond, according to Washington State Legislature . This specific timeframe and forfeiture mechanism apply to the jurisdiction defined by that statute.

Deposit return procedures follow a similar jurisdictional path. When the contract is let, all bid proposal deposits shall be returned to the bidders, except that of the successful bidder, which shall be retained until a contract is entered into and a bond to perform the work is furnished with surety satisfactory to the council or commission, in accordance with RCW 39.08.030, reported by Washington State Legislature . The retention of the successful bidder's deposit is contingent on the subsequent execution of the contract and the provision of a satisfactory performance bond.

Dispute resolution mechanisms are defined differently in other state codes. In Ohio, a "dispute" is defined as a disagreement between the state and the contractor concerning a public improvement contract let by the state, as stated in Ohio Laws . This definition sets the scope for which disagreements trigger specific legal procedures under the Ohio Revised Code.

If a dispute arises between the owner and the contractor concerning a change order, procedures shall be commenced under the applicable terms of the contract, or, if the contract contains no provision for resolving the dispute, it shall be resolved pursuant to the procedures for arbitration in Chapter 2711. of the Revised Code, except as provided in division (B) of this section, according to Ohio Laws . This provision establishes a fallback arbitration process for contracts that lack specific dispute resolution clauses.

Verify that your project contracts explicitly reference the applicable state arbitration chapters or bond forfeiture timelines to ensure procedural clarity.

Retainage rules vary by jurisdiction, so verify your contract against the specific state statutes that govern your project. In Washington, the public body must release and pay in full the amounts retained during contract performance sixty days after completion of all contract work, subject to the provisions of chapter 39.12 RCW and this chapter, according to Washington State Legislature . This timeline applies to the final release of funds held back during the project's execution.

Contractors in Washington may withhold payment of not more than five percent from the moneys earned by any subcontractor, sub-subcontractor, or supplier contracted with by the contractor to provide labor, materials, or equipment to the public project, reported by Washington State Legislature . This withholding limit applies to funds earned by lower-tier parties involved in the public project. The contract bond must remain in full force and effect until, at a minimum, all claims filed in compliance with chapter 39.08 RCW are resolved, published by Washington State Legislature . Bond duration is tied directly to the resolution of compliant claims rather than a fixed calendar date.

Ohio law provides different standards for partial payments. Partial payments to the contractor for labor performed under either a unit or lump sum price contract shall be made at a rate of not less than ninety-six percent of the estimates prepared by the contractor and approved by the architect or engineer, according to Ohio Laws . This requirement ensures that contractors receive a substantial portion of the approved estimate during the project lifecycle. For estimate approval steps, see partial billing rules for estimate approval .

Retainage release is a critical milestone that affects cash flow for the entire project team. The sixty-day release window in Washington provides a clear deadline for the public body to finalize payments. The five-percent withholding limit protects subcontractors from excessive holdbacks while allowing the contractor to secure performance. The bond duration requirement ensures that financial security remains in place until legal claims are settled.

Correct project classification determines which wage determination applies to your labor costs. Misclassification can lead to incorrect wage rates and potential compliance violations. Use the definitions provided by federal and state sources to ensure your project is categorized accurately before finalizing your bid or contract.

Defining highway construction

According to Acquisition.gov , highway construction is generally the construction, alteration, or repair of roads, streets, highways, runways, taxiways, alleys, parking areas, and other similar projects. This definition specifically excludes projects that are incidental to "building," "residential," or "heavy" construction. Classify that work as highway construction only when it is not incidental to building, residential, or heavy construction.

Defining building construction

Acquisition.gov also defines building construction as generally the construction of sheltered enclosures with walk-in access. These enclosures are intended for housing persons, machinery, equipment, or supplies. Erecting such enclosures is generally classified as building construction.

Estimating costs for bid transparency

Proper classification also affects how you present cost estimates in your bid documents. Ohio Laws requires public owners to include the estimate of cost in the plans and specifications for the project for which bids are solicited. This ensures that bidders have a baseline for understanding the project's financial scope.

Detailing government estimates

For federal projects, detail rules apply to the Government estimate of construction costs, not to a bidder's own estimate. Acquisition.gov states that the estimate shall be prepared in as much detail as though the Government were competing for award.

Including scope in bid invitations

State laws also mandate specific content in bid invitations. Washington State Legislature requires that invitations for bids or direct contract negotiation include, at a minimum, an estimate for the scope of work. This estimate must detail the nature of the work to be performed as well as the materials and equipment to be furnished. Ensuring these elements are present helps bidders accurately classify the project and price their labor accordingly.

Action step

Today, review your current project scope against these definitions. Classify roads, runways, or parking areas as highway construction only when that work is not incidental to building, residential, or heavy construction. Construction of sheltered enclosures with walk-in access for housing persons, machinery, equipment, or supplies is generally building construction. Check that Ohio plans include the estimate of cost, Washington invitations include a scope estimate, and the Government estimate is prepared as though the Government were competing for award.

How long must a contractor preserve certified payrolls after work is completed?

According to Legal Information Institute , the contractor or subcontractor must preserve all certified payrolls during the course of the work and for 3 years after all the work on the prime contract is completed. These records must cover all laborers and mechanics working at the site or otherwise working in the construction or development of the project under a development statute.

What happens if a successful bidder fails to furnish a bond within 10 days?

According to Washington State Legislature , if a bidder fails to enter into the contract and furnish a bond within 10 days of notification, the check or postal money order is forfeited to the council or commission. Alternatively, the council or commission may recover the amount of the surety bond.

When must a public body release retainage after contract completion?

Washington State Legislature states that 60 days after completion of all contract work, the public body must release and pay in full the amounts retained during performance. This release is subject to the provisions of chapter 39.12 RCW and the relevant chapter.

How is highway construction defined for classification purposes?

Acquisition.gov defines highway construction as generally the construction, alteration, or repair of roads, streets, highways, runways, taxiways, alleys, and parking areas. This classification applies to similar projects that are not incidental to "building," "residential," or "heavy" construction.
