Site Work Estimating Services · Earthwork Move the dirt before the machines do.
A dedicated site work estimator, working as part of your shop — mass and structural excavation, cut/fill balancing, grading, utilities, and erosion control, with quantities pulled straight from the surfaces and priced to your equipment and haul distances. Full-time, part-time, or as-needed.
15 days of free estimating is available to qualified contractors, subject to approval. If you choose to continue afterwards, service moves to a quarterly agreement (3-month term) that renews each quarter until cancelled — full-time, part-time, or as-needed.

Market figures are typical industry estimates and vary by region and role.
Every site work scope, quantified and priced.
From the first cut to final grade — we quantify the earthwork, the utilities, and the site protection, then price it against your fleet and haul distances so your bid is both competitive and defensible.
Mass & structural excavation
Bulk cut, structural digs, and over-excavation — bank cubic yards computed from existing vs. proposed surfaces.
Cut / fill balancing
Earthwork balance with swell and shrink factored, so import and export volumes reflect the real haul, not raw geometry.
Grading & subgrade prep
Rough and fine grading, proof-rolling, and subgrade correction quantities tied to the finish surface.
Trenching & utilities
Storm, sanitary, and water runs — trench excavation, bedding, backfill, and structures by depth zone.
Erosion control & SWPPP
Silt fence, inlet protection, stabilized entrances, and seeding measured to the disturbed-area plan.
Aggregate base & haul-off
Stone base and subbase tonnage, plus import and export truckloads sized to your equipment and route.
Earthwork calculator.
Rough your dig volume and haul in seconds. A quick planning check — your dedicated estimator delivers the full, surface-based takeoff.

Site work estimating services — common questions
What does a site work estimate include?
A site work estimate covers mass and structural excavation, cut/fill balancing, grading, site utilities, paving subgrade, and erosion control. Quantities are pulled from existing and proposed surfaces, then priced to your equipment, crew spreads, and haul distances. Assumptions about soils, import and export, and dewatering are documented so your number holds up.
What software do your site work estimators use?
Any of the 100+ tools you already run. Our site work estimators work natively in your software, templates, and cost data — AGTEK, Trimble Business Center, and Carlson Takeoff are common examples — and deliver in your format, ready to drop into your bid. Your team also gets Build Intel, our AI-assisted estimating software for drawing review and QC checks.
Can I hire a part-time site work estimator?
Yes. Many clients start with a part-time or as-needed site work estimator and move to full-time as their bid list grows. Your estimator is dedicated to your company, trained on your standards and past bids, and backed by our QA and management, so you can chase more site packages without hiring, training, or covering PTO yourself.
How fast can you start site work estimating for us?
Most clients finish the free assessment and setup in about an hour, with their estimator typically on their bids in under 7 days. We review your site work scope, software, and the bids you're chasing, then map the estimator or team we'd assign. Timelines for individual bids depend on project size and drawings, so we agree on them bid by bid rather than promising a fixed turnaround.
Is your site work estimating AI-enabled?
Yes. Every site work estimating team we build works with Build Intel, our AI-assisted estimating software, and Dexter, our AI co-estimator, which reads drawings and specs and gives cited answers. AI speeds up the first draft; your dedicated estimator checks every quantity and our QA team reviews the work before it reaches you. You review and approve the final bid.
How fast can I get an estimator?
Typically in under 7 days. The free assessment and setup take about an hour; then we match a dedicated estimator trained for your trade, and most clients have that estimator on their bids in under 7 days. It is a good-faith target, not a guarantee — timing depends on your trade, software, and bid volume.
