Overhead Audits


Focused on Your Needs

The issues faced by A/E firms in contracting with local, state and federal agencies are complex – that’s why it’s critical to engage a CPA firm that specializes in performing overhead rate audits of A/E firms.

At D. L. Purvine, CPA, PLLC, that’s all we do. We have extensive experience in the A/E industry, working with firms like yours. Unlike many firms, we don’t dabble in this industry - we live and breathe A/E firm issues, government contracting, and overhead rates. Here are some highlights of what sets us apart:


Our practical experience in the A/E industry is unmatched. Our team members helped to write the AASHTO Audit Guide and have worked for years with all of the state DOTs to promote consistent application of FAR Part 31 and other regulations. Our team members bring substantial experience and unique perspectives to the table. You will benefit from our experience, to improve your processes and maximize your profitability on government contracts.


As important as experience is the trust that a CPA firm has developed in the eyes of your clients – most importantly, your home state DOT. While relationships are important, trust goes far beyond knowing a name or a face. We’ve developed the trust of your DOT clients through years of working together in a collaborative relationship to further both their goals and the goals of the A/E industry. It’s trust that we value above all, and we refuse to sacrifice quality in our work, because that trust is so critically important, to us and to you.


D.L. Purvine, CPA is a small firm, allowing us to be nimble, responsive and highly personable with your needs. In short, your goals are our goals. We believe those should include an overhead rate that includes the full amount of your FAR-allowable costs, an audit performed efficiently and accepted by your state DOT clients with minimal stress, and the added value of our expertise to improve your processes and make FAR compliance an integrated part of your business.


We recognize that audits cost both money and time, and we work hard to achieve the right balance for our clients.  When choosing a firm to provide your company’s overhead audit, we strongly advise against making a decision based on price alone. We strive to provide the best value, which includes an audit performed in accordance with professional standards and the expectations set out in the AASHTO Audit Guide, a fixed audit fee, and comprehensive suggestions for improvements to your systems and controls. We help our clients to work through the state DOT approval process, including cognizant approval where applicable, at no additional charge, except in rare cases. We are in your corner, and when our audit is complete and the report is issued, we will assist you in supporting that rate for acceptance every step of the way. It’s as important to us as it is to you.

This is also the time of year when many of you are going through the annual review of your overhead rate by one or more state DOTs.
