It can provide an independent or objective view of the progress and conditions of the site. You must identify gaps and areas for improvement.

Construction site audits can be performed internally or by external parties. Individuals may choose to initiate an audit. Sometimes it is the client or the architect who wants to see if the project is going according to plan. Other times it may be the main contractor who wants to check if their subcontractors are sticking to the financial agreements. Sometimes a government agency may conduct a site audit, especially for things like health and safety.

Which Approach is more Effective?

Consider how your team will implement your review. Will they be involved from the start of a construction project? Will construction review (Internal Audit Procedure) be made an integral part of construction activities? Or will the review be part of the project before the final payment or advance is released? Each approach will provide value, however, by creating a “trusted but verified” feeling to the overall project that the construction compliance professionals involved will have from the start of the project.

This can lead to more compliant behavior on the part of contractors without hampering the progress of the project. On the other hand, just involving your compliance team in the project closeout process can delay final payments to contractors due to the time investment for data collection and review.

Why do you need to involve an auditor?

While the construction manager and owner’s representative generally oversee the financial aspects of the project, their role differs from that of an auditor. Consider the role of construction manager. It focuses on the project, schedule, contractors, and construction methods.

That person also focuses on finances but from the contractor’s point of view. If an owner’s representative is involved, this person focuses on managing construction resources, advising the owner on construction methods and procedures, and ensuring adherence to the architect’s plan and schedule. It also reviews the contractor’s request for payment to determine if it is appropriate.

What the auditor contributes focuses on consolidating financial control over the process. He audits financial transactions to ensure contract compliance and works with the owner’s representative to manage the entire process. The auditor reviews the cost structure of the project, which includes subcontractor costs, purchase order costs, contractor relationships, and contract performance.
