Arizona Construction Project Insurance and Contract Surety

For public buildings and public works let by counties, cities, towns and many special districts, A.R.S. §34-222 requires the contractor to furnish two bonds before the contract is executed. The performance bond is 100 percent of the contract amount and runs solely to the public body. The payment bond is also 100 percent and runs solely to claimants who supply labor or materials to the contractor or its subcontractors.

The statute also controls who can write the bonds. Each must come from a surety company authorized by the Arizona Department of Insurance and Financial Institutions, individual sureties are not allowed and the bid solicitation cannot require a particular surety or agent. If the prime contract requires subcontractor bonds, those bonds must meet the same standard.

These are surety obligations, not insurance. The surety answers to the obligee or to unpaid claimants, and the contractor that signed the general indemnity agreement owes the surety for any loss it pays. That is why a surety reviews financial statements, work in progress and backlog before it sets a single-job or aggregate program.

Arizona's alternative delivery statutes add their own surety step. Under A.R.S. §34-608, a design-build proposal above the statutory threshold must carry bid security equal to 10 percent of the agent's construction budget stated in the request for proposals. For job-order contracting, the agent sets the amount, but it cannot exceed 10 percent of the estimated construction spending for the contract's first year.

Bid security may be a certified check, a cashier's check or a surety bond from a surety licensed in Arizona. If the selected proposer does not sign the contract or deliver the required performance and payment bonds and insurance, the obligee can recover the difference up to the bond's penalty. A proposal without the required security is generally rejected unless the agent finds the defect nonsubstantial.

For contractors, the practical point is timing. The surety needs to see the design-build or JOC opportunity early enough to approve the bid bond and confirm that the final bonds will follow, and the insurance program specified in the agency's standard specifications should be priced before the proposal is irrevocable.

A.R.S. §34-221 sets the payment terms written into public works contracts let under that article. The owner makes monthly progress payments on contracts of 90 days or longer, an estimate is deemed certified seven days after submission unless the owner issues a specific written finding and payment is due no later than 14 days after certification.

Retention is 10 percent of each estimate. Once the contract is 50 percent complete, half of the amount retained is paid on the contractor's request if progress is satisfactory and no specific claim requires more, and later progress payments may be retained at no more than 5 percent. The owner can reinstate 10 percent retention if satisfactory progress stops.

Retention matters to surety and insurance planning in two ways. A surety reads retained balances as part of the contractor's working capital picture, and the timing of final acceptance often lines up with when ongoing operations end and completed operations exposure begins under the liability program.

A.R.S. §12-552 bars contract-based actions and arbitrations against persons who develop real property or who design, plan, supervise or build improvements more than eight years after substantial completion. Implied warranties, including habitability and workmanship, fall under the same limit. If an injury to property occurs or a latent defect is discovered in the eighth year, the claimant has one more year, but no action may be brought more than nine years after substantial completion.

Substantial completion has a statutory meaning: the earliest of first use by the owner or occupant, first availability for use under the contract or final inspection by the permitting body where one is required. That date is worth documenting for every building or phase.

The repose period does not apply to personal injury or death claims and does not shorten an express written warranty. For insurance planning, it frames how long completed operations exposure can realistically run, which is one input when a developer or GC compares a project-specific completed operations term with relying on annual policies renewed year after year.

Three more Arizona regimes reach most site-heavy projects. The underground facilities law in A.R.S. §40-360.21 et seq. requires excavators to white-line the dig area and request locates through the one-call notification center, and it makes a violator liable for damages proximately caused, including economic loss. Civil contractors feel that rule most directly.

Stormwater runs through the AZPDES program the Arizona Department of Environmental Quality administers under A.R.S. §49-255.01, which authorizes general permits for discharges of stormwater from construction activity. Subsection L directs reduced control measures for qualifying sites that retain stormwater on site, so a project's drainage design can change what the permit asks of it.

Subdivision improvements carry their own security. A.R.S. §9-463.01 requires municipalities to require performance bonds, assurances or other security for streets, sewer, utilities, drainage and flood control improvements, and the Department of Real Estate's public report process adds a separate completion-assurance test before lots are sold.

Developers and subdividers usually meet Arizona law first through improvement assurances and the public report. The form of assurance a city, county or the Real Estate commissioner accepts can decide whether a subdivision improvement bond, a letter of credit or a recorded trust arrangement fits the capital plan.

General contractors meet it through ROC classification, the license bond and, on public work, the §34-222 bonds and §34-221 payment terms. Civil and underground contractors meet it in the field, through the one-call rules and the horizontal public work they bid.
