Plan-based quantity takeoffs
Identify the current drawing revision, included systems, alternates and addenda. Agree whether labor, equipment, demolition, testing, permits, taxes, freight and owner-furnished items are included. Missing design information needs a recorded allowance or clarification; estimating does not replace engineering design or code approval.
Keep measured quantities separate from waste and procurement allowances. For a priced estimate, confirm the project location, pricing date, supplier inputs and labor basis. Final bid qualifications and markups remain subject to contractor review.
In civil earthwork, soil bank cubic yards (BCY), loose cubic yards (LCY), and compacted cubic yards (CCY) dictate equipment cycle times and trucking costs. Underestimating topsoil stripping depths or soil swell/shrinkage factors can lead to catastrophic budget shortfalls.
Existing/proposed contours, soil borings, rock layers & water tables
Digital terrain triangulation, cut/fill grids & balance (CY)
Tree clearing, asphalt/concrete pavement demo & stripping

Deliverable Format
Cut/Fill 3D volume reports in Cubic Yards (CY), topsoil quantities, and haul-off truck counts.
Our sitework takeoffs strictly conform to CSI MasterFormat Division 31 (Earthwork) and Division 32 (Exterior Improvements) standards.
Every civil scope is categorized by construction phase from mass clearing to final paving.
Tree clearing, grubbing, topsoil stripping, and pavement demolition.
Mass grading, bulk cut/fill, building pad prep, and trenching.
Silt fences, inlet protection, sediment basins, and rock dams.
Crushed stone aggregate base, lime stabilization, and geogrids.
Hot-mix asphalt base and surface courses, sealcoating, and striping.
Cast-in-place concrete curbs, pedestrian sidewalks, and ramps.
Segmental block retaining walls, geogrids, and drainage backfill.
Earthwork estimating requires building digital 3D surface meshes from civil C-sheets, comparing existing ground contours with proposed finished grades, subgrade paving depths, and topsoil respread layers to compute true mass excavation balance.
Send your drawing sheets for a dedicated takeoff schedule.
Reference conversion factors applied by our sitework estimators:
Understanding whether your team needs raw quantity measurements or a fully priced bid estimate helps you order the exact service you require.
Our systematic 7-step engineering process eliminates missing elements, prevents duplicate counts, and delivers defensible estimates.
We review existing/proposed contour plans, grading sheets, paving details, soil borings, and Division 31/32 specs.
Using AGTEK and Trimble, we digitize existing and proposed contours to generate a 3D terrain mesh model.
We calculate gross cut/fill volumes, adjust for topsoil stripping and paving subgrades, and establish net dirt balance.
We measure pavement areas, calculating required crushed stone base tons, asphalt binder tons, and surface topping tons.
We measure curb linear footage, concrete sidewalk square footage, ADA truncated dome pavers, and dumpster pads.
We extract silt fence, inlet filters, and calculate equipment fleet hours (excavators, dozers, rollers, trucks).
A Senior Civil Estimator conducts a peer review to verify soil compaction factors, paving densities, and addenda.
From commercial tenant fit-outs to heavy industrial complexes, we adapt our takeoff methodology to project specifications.
Mass grading over 20+ acres, heavy-duty asphalt truck aprons, concrete loading docks, and stormwater detention ponds.
Parking lot grading, crushed stone base, asphalt surface, concrete barrier curbs, ADA walkways, and retaining walls.
Roadway rough grading, curb & gutter installation, asphalt street paving, soil stabilization, and sediment basins.
Campus pedestrian walkways, parking lots, athletic field mass grading, retaining walls, and perimeter security fencing.
Emergency vehicle access lanes, helicopter pad grading, permeable concrete pavements, and decorative plaza flatwork.
Roadway widening, asphalt milling, overlay paving, concrete barrier rails, and stormwater drainage ditches.
Material and labor costs fluctuate drastically by project geography, supplier logistics, trade union jurisdictions, and site conditions. We do not use flat national averages.
Confirm the pricing date, project ZIP code, supplier quotations, labor basis and equipment allowances in the project brief. Identify any owner-supplied rates or provisional costs separately.
A balanced site eliminates expensive off-site import fill or export trucking fees ($12–$20/CY).
Subsurface bedrock requiring hydraulic hammer hoe-rams or blasting increases excavation unit costs by 4x to 8x.
Crude petroleum market fluctuations directly impact hot-mix asphalt (HMA) plant mix prices per ton.
Wet, unstable clay soils require lime or Portland cement subgrade stabilization to achieve required compaction.
Transporting heavy 40-ton excavators, scrapers, and bulldozers incurs lowboy transport permits and freight.
Review illustrative project models demonstrating how CSI Divisions 31 & 32 Sitework quantities are extracted, itemized, and structured under standard contractor bidding conditions.
Agree the scope and review requirements for your project. Check quantities against the supplied drawing revision and record unresolved items before preparing a final bid.
When bidding tight commercial deadlines, subcontractors cannot afford incomplete takeoffs or guesswork. A clear estimating brief helps identify the quantities, pricing inputs and qualifications needed for bid review.
Request drawing references and identify allowances separately from measured quantities.
Identify addenda and agree the revision scope, fee and delivery date.
Confirm the spreadsheet format, formulas and cost inputs required for your bid.
Confirm the project ZIP code, pricing date, supplier quotations and labor basis.
Detailed technical and commercial answers to help you navigate sitework estimating services, material scheduling, and bid preparation.
For a contractor bid, identify the trade package, issued plan revision, specifications, alternates and the responsibility for adjoining work. Separate measured quantities from unit prices, subcontractor quotations and project allowances so the bid reviewer can trace each assumption.
Agree the spreadsheet columns, drawing references, exclusions, pricing date and revision allowance before work starts. An addendum or changed scope needs an identified issue date and change record; an illustrative sample does not establish project-specific pricing or specialist experience.
Compare commercial bid estimating scope with the published sample evidence, then request the required handoff.
