Why an independent estimator
Numbers with no agenda but yours.
Senior judgment
Your project is estimated by a principal with three decades of experience, not handed to a junior. The hard calls are made by the person who's seen them before.
Early & continuous
The costliest scope is the scope no one drew yet. We engage early and stay through design, catching cost before it becomes a change order.

The approach
Estimating is part science, part judgment.
Anyone can price what's on the drawings. The value is in seeing what isn't — the scope, the conditions, and the risk the documents don't yet show. That's where 30 years earns its keep.
30.Years earning its keep
Engage early
We get involved while decisions are still cheap to change.
Define the unknown
We price the scope the drawings imply, not just the scope they show.
Anchor to today's market
Current local pricing and real subcontractor conditions, not stale unit costs.
Monitor through design
Estimates that travel with the project, so surprises surface early.
Deliver decisions, not data
Formats organized around the choices you actually have to make.
