I'm Bret McMillan, a civil engineer and the founder of Dirtwork Calcs. I started this company to fill a critical need I saw in the construction industry: providing earthwork contractors with precise, reliable takeoff and estimating services.

Having spent 25+ years in the field, I understand the complexities and challenges of earthwork projects. I know that a precise bid can be the difference between winning a job and losing a chance at profitability. My mission is to give you a competitive edge by delivering detailed, accurate data you can trust.

My personal life as a husband and father has taught me the importance of being dependable and building a solid foundation. That same dedication and attention to detail are what I bring to every client project, ensuring your work is handled with the same care and integrity that I value most.

At Dirtwork Calcs, every calculation is handled with the expertise of a civil engineer. I am committed to helping you streamline your pre-construction process so you can stop worrying about the numbers and focus on what you do best—getting the job done right.
