Construction Audits: Common Issues and Frequently Asked Questions

Assurance Services

Questions about construction audits usually concern requirements, scope, assurance, timing, records, and the meaning of the final report. This page addresses the most common issues in plain English and identifies the decisions management should settle before engaging a CPA.

The issues that deserve attention first

Construction accounting turns project-level estimates into company-level financial reporting. Revenue, gross profit, contract assets and liabilities, retainage, claims, change orders, equipment, and overhead allocations all depend on disciplined job-cost records and current estimates to complete.

The most effective response is not to create more year-end spreadsheets. It is to establish a close process in which operational records, subsidiary systems, the general ledger, and the financial statements reconcile on a repeatable schedule.

• Stale estimates to complete that overstate profit on active jobs
• Unapproved change orders or disputed claims included in revenue too early
• Costs charged to the wrong job, period, or overhead pool
• Missing accrued subcontractor, payroll, equipment, or closeout costs
• WIP schedules that do not reconcile to the ledger or project-management system

How to reduce the risk

Management can improve both reporting quality and audit efficiency through a small number of durable practices:

• Close and reconcile significant accounts monthly, with evidence of preparation and review
• Maintain current contracts, policies, minutes, approvals, estimates, and third-party reports in a controlled repository
• Assign ownership for every material schedule and document the source, method, assumptions, and review
• Investigate unusual trends and old reconciling items before the auditor asks about them
• Communicate new transactions, disputes, financing, system changes, control failures, and suspected fraud promptly
• Perform a pre-audit quality review using the prior-year adjustments and management comments as a checklist

Frequently asked questions

Why is the WIP schedule central to a contractor audit?

It connects contract price, cost incurred, estimated cost to complete, billings, and recognized revenue. Small changes in estimates can materially change reported profit, contract assets, and contract liabilities.

Do auditors visit job sites?

They may. Site visits are not mandatory in every audit, but they can help the auditor understand progress, stored materials, equipment, physical conditions, and whether project records align with operations.

How are pending change orders handled?

Treatment depends on enforceable rights, approval status, probability, measurement, and the applicable accounting framework. Management should maintain a change-order log with contract support and a documented accounting conclusion.

What causes margin fade?

Common causes include underestimated labor or material costs, productivity problems, schedule delays, subcontractor failures, scope disputes, rework, warranty costs, and incomplete estimates to finish.

Can an audit improve bonding conversations?

A timely audit can give a surety more reliable information, but bonding decisions also consider backlog, working capital, net worth, experience, indemnity, project mix, and the surety's underwriting standards.

When should the audit process start?

Coordinate before year-end so contract selections, confirmation contacts, inventory or equipment observations, cutoff procedures, and WIP responsibilities are settled while evidence is readily available.

Questions to ask a prospective CPA firm

The engagement partner should be able to answer practical questions before appointment:

• What experience does the team have with construction audits and the applicable reporting framework?
• Which standards, regulatory guides, contractual provisions, or submission requirements will govern the work?
• Who will manage the engagement day to day, and when will the partner communicate with management and governance?
• What information is needed before fieldwork, what will be selected later, and how will secure documents be exchanged?
• What assumptions support the fee and timetable, and how will scope changes or readiness problems be handled?
• What independence, licensing, peer review, quality management, specialist, or continuing education considerations apply?

Choosing the right assurance level

An audit provides reasonable assurance and an opinion on the financial statements. A review provides limited assurance principally through inquiry and analytical procedures. A compilation presents financial information with no assurance. Compliance examinations, agreed-upon procedures, single audits, and program-specific engagements have different objectives and should not be substituted solely because their names sound similar.

Start with the exact user requirement and the decision the report must support. Selecting too little assurance can lead to rejection and rework; selecting more than users need can add cost and time without a corresponding benefit.

Next step

Schedule a scoping discussion with Dohan CPA to review the reporting requirement, intended users, current records, prior reports, and deadline for construction audits. The firm should confirm engagement acceptance, independence, staffing, and final scope before any service is promised.
