OneEstimate — For civil & sitework contractors

Civil work is won on takeoff and markup

Cubic yards of concrete, tons of rebar and markup. Here is what OneEstimate fixes.

Taking off volumes and areas by hand

Calculating CY of concrete, SF of slab or tons of rebar on a PDF is slow and error-prone. Take off on the plan and quantities flow into your line items.

Material prices that keep moving

Cement, steel, aggregate and fuel move. Update them once and the whole estimate recalculates.

Markup done by hand with errors

Overhead and profit define your margin. Apply markup on direct cost clearly and traceably.

Bids that don’t hold up in review

A proposal with itemized unit prices and visible markup passes review better than an unsupported lump sum.

4. Send the proposal

Export a professional PDF or Excel with unit prices and markup. Ready to bid.

Use case

A bidding day: civil contractor with OneEstimate

The concrete foundation and structure of a job need a bid. The contractor measures concrete volumes for footings, columns and slabs off the plan, along with formwork area and rebar length. OneEstimate totals each quantity in its own unit (CY, SF and pounds) and every line item carries its assembly of material, labor and equipment. Close the takeoff and quantities and cost line up.

  • Concrete volumes (CY), formwork (SF) and rebar measured from the plan.
  • Reusable assemblies for footings, columns, beams and slabs across jobs.
  • Change concrete or steel pricing and everything recalculates.

Frequently asked questions

How do I estimate civil work faster instead of calculating volumes by hand?
With OneEstimate you measure concrete volumes, formwork areas and rebar lengths right on the plan, and everything drops into ready assemblies with markup. Manual calculation becomes minutes.
How do I calculate concrete volume (cubic yards) and rebar from a plan?
Calibrate the scale and measure footing, slab and member dimensions to get volume in cubic yards, formwork in square feet and rebar by length. OneEstimate measures volumes, areas and lengths on the same plan.
Is OneEstimate an alternative to expensive software for civil estimating?
Yes. It covers everything from earthwork to finishes with editable assemblies, on-screen takeoff and markup, with a Start plan from $19/mo. A complete, affordable alternative for contractors.
Can I estimate full civil projects?
Yes. It covers everything from earthwork and foundations to structure, masonry, finishes and sitework, with editable assemblies and markup.
Does it handle markup (overhead & profit)?
Yes. Apply overhead and profit on direct cost clearly and traceably, the way a formal bid requires.
Can I take off quantities on the plan?
Yes. Upload the plan as a PDF, image or DWG, calibrate the scale, then take off areas, lengths and volumes. Quantities flow into the line items.
How much does it cost?
There is a Start plan from $19/mo for your first estimate. Paid plans are accessible and scale with you.
Do I need to install anything?
No. It runs 100% in the browser on Windows, Mac or tablet, with automatic backup.
