Construction Audits: Independent Assurance for Better Decisions
A pillar guide to construction company audits — when one may be required, what the engagement covers, how the process runs, and how Dohan CPA supports readiness.
Assurance Services
Dohan CPA provides construction audits for general contractors, specialty contractors, subcontractors, developers, sureties, lenders, and owners that rely on credible financial statements. Our objective is financial statements that explain contract performance, backlog economics, cash needs, and the risks embedded in work in progress. This guide explains when the service may be needed, what the engagement addresses, how the process works, and how management can prepare.
Who construction audits are for
Dohan CPA's construction audits are designed for general contractors, specialty contractors, subcontractors, developers, sureties, lenders, and owners that rely on credible financial statements. The engagement is organized around the reporting needs of the people who will actually use the statements, rather than treating the audit as a generic year-end exercise.
The intended result is financial statements that explain contract performance, backlog economics, cash needs, and the risks embedded in work in progress. Management remains responsible for the financial statements, underlying records, estimates, controls, and representations; the independent CPA is responsible for planning and performing the engagement and reporting in accordance with the applicable professional standards.
When an audit may be needed
Contractors commonly obtain audits because a surety, bank, investor, owner, acquisition process, or governance body requests them. The appropriate reporting framework and assurance level should be matched to the intended users and deadlines before fieldwork begins.
Before accepting a timetable or quote, identify the reporting entity, fiscal period, financial reporting framework, intended users, required report language, delivery date, and any compliance or supplemental schedules. A requirement in a loan, contract, statute, regulatory agreement, or governing document should be read directly rather than summarized from memory.
What makes this engagement different
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.
A strong engagement therefore combines technical accounting, industry knowledge, disciplined project management, and timely communication. The audit is more efficient when key schedules reconcile before fieldwork and questions are routed to people who understand the underlying transaction.
Areas commonly addressed
The scope is risk-based and tailored to materiality and the applicable standards. Common areas include:
- Revenue recognition under the applicable framework, including identification of performance obligations and measure of progress
- Job-cost completeness, cost-to-cost calculations, estimates to complete, and approved or pending change orders
- Contract assets, contract liabilities, billings, retainage receivable, and retainage payable
- Loss contracts, claims, unapproved change orders, liquidated damages, warranties, and contingencies
- Equipment ownership, depreciation, leases, repairs, capitalization, and related-party arrangements
- Backlog, bonding capacity, covenant calculations, cash-flow pressures, and concentration risk
Our audit approach
The exact procedures vary with assessed risks, but a well-managed engagement commonly includes the following work:
- Understand estimating, contract approval, job setup, purchasing, timekeeping, billing, change-order, and closeout controls
- Select contracts and agree terms, approved modifications, billings, collections, costs, and estimated margins
- Compare current forecasts with prior estimates and investigate margin fade, gain, and unusual cost movements
- Test costs to payroll, invoices, subcontracts, equipment records, and proper job or overhead classification
- Evaluate revenue cut-off, subsequent billings and collections, loss provisions, claims, and commitments
- Reconcile the work-in-progress schedule to the trial balance and evaluate related disclosures
What the audit does and does not provide
A financial statement audit is designed to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether caused by error or fraud, and to support the auditor's opinion. Reasonable assurance is a high level of assurance, but it is not absolute assurance and an audit is not a guarantee that every error, control deficiency, improper payment, or instance of fraud will be found.
An audit also does not replace management's responsibilities, provide legal advice, determine the value of a business or property unless separately engaged, or predict future results. Findings and recommendations should be evaluated in the context of the engagement's objective and the organization's risk tolerance.
A practical timeline
Planning should begin before year-end. During planning, confirm scope, independence, deadlines, material locations, confirmation contacts, specialists, prior findings, and client-prepared schedules. After year-end, management closes the books and delivers reconciled schedules. The CPA performs fieldwork, communicates open items, evaluates adjustments and disclosures, obtains representations, and issues the report after all required evidence and approvals are complete.
Calendar time depends on readiness and responsiveness as much as auditor hours. Missing reconciliations, changing trial balances, incomplete contracts, slow third-party confirmations, and late legal or governance information are common causes of delay.

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.
