A Message From Our CEO
The vision, the mission and the commitment behind DO Estimating in the words of the person who built it from the start.

Why I Built DO Estimating?
When I started my career in construction more than two decades ago, I quickly learned one hard truth: the contractors who won the most work were not always the most skilled, they were the ones who showed up with the sharpest numbers. I spent years watching talented subcontractors lose bids they deserved to win not because their work was inferior, but because their estimates were rushed, incomplete, or simply wrong.
And I watched general contractors spread themselves too thin, estimating late at night and days, just trying to keep their pipeline full. That’s why I founded DO Estimating. The name carries a double meaning: it’s built from my initials and it reflects what we do: we do the estimating, so you don’t have to.
Our mission:
Has always been simple: provide contractors of all sizes with the same caliber of professional estimating support that large firms have on staff, without the overhead, without the complexity and without the long term commitment.


You send us your plans. We deliver you bid ready numbers. You win more work. Every estimate we create is a reflection of this company’s values: accuracy, integrity, speed and respect for your time. We know that a wrong number in an estimate can cost you thousands.
We know that a missed deadline means a missed opportunity. We take that responsibility seriously and so does every member of this team.I’m proud of what we’ve built here and I’m proud of every contractor we’ve helped win a project they otherwise might have passed on. If you’ve never worked with us before, I’d like to earn your trust, one estimate at a time.
David O. Merritt
