What Is Sitework Estimating?
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.
At F&K Estimatings, our sitework estimators use AGTEK 3D, Trimble Earthworks, Planswift, and Bluebeam Revu to build digital terrain surface models (existing vs proposed contours), calculate exact cut/fill earthwork balance, and price heavy equipment fleets (excavators, scrapers, dozers, rollers).

Sitework Takeoff vs. Complete Sitework Estimating
Understanding whether your team needs raw quantity measurements or a fully priced bid estimate helps you order the exact service you require.
F&K Sitework Estimating Services Quantification & Review Workflow
Our systematic 7-step engineering process eliminates missing elements, prevents duplicate counts, and delivers defensible estimates.
Civil Plan & Geotechnical Audit
We review existing/proposed contour plans, grading sheets, paving details, soil borings, and Division 31/32 specs.
3D Surface Modeling & Triangulation
Using AGTEK and Trimble, we digitize existing and proposed contours to generate a 3D terrain mesh model.
Cut & Fill Volumetric Balance Calculation
We calculate gross cut/fill volumes, adjust for topsoil stripping and paving subgrades, and establish net dirt balance.
Aggregate Base & Asphalt Paving Takeoff
We measure pavement areas, calculating required crushed stone base tons, asphalt binder tons, and surface topping tons.
Concrete Curbs, Walks & Hardscape Takeoff
We measure curb linear footage, concrete sidewalk square footage, ADA truncated dome pavers, and dumpster pads.
SWPPP Erosion Control & Fleet Allocation
We extract silt fence, inlet filters, and calculate equipment fleet hours (excavators, dozers, rollers, trucks).
Senior Civil Estimator QA

Sitework Estimating Services Elements We Quantify
How Sitework Estimating Services Costs Are Calculated
Material and labor costs fluctuate drastically by project geography, supplier logistics, trade union jurisdictions, and site conditions. We do not use flat national averages.
Our cost database integrates regional material supplier pricing, union prevailing wage scales, open-shop labor rates, and local equipment rental benchmarks across all 50 U.S. states.
On-Site Soil Balance vs Off-Site Haul
A balanced site eliminates expensive off-site import fill or export trucking fees ($12–$20/CY).
Rock Excavation & Blasting Requirements
Subsurface bedrock requiring hydraulic hammer hoe-rams or blasting increases excavation unit costs by 4x to 8x.
Liquid Asphalt Index Fluctuations
Crude petroleum market fluctuations directly impact hot-mix asphalt (HMA) plant mix prices per ton.
Subgrade Soil Moisture & Stabilization
Wet, unstable clay soils require lime or Portland cement subgrade stabilization to achieve required compaction.
Equipment Mobilization & Freight Distances
Transporting heavy 40-ton excavators, scrapers, and bulldozers incurs lowboy transport permits and freight.
