Sitework Estimating and 3D Earthwork Takeoffs
Commercial and civil sitework estimating services across the USA. We calculate 3D cut/fill earthwork balances, storm/sanitary pipe runs, asphalt paving square yards, and SWPPP compliance with 99% accuracy.
3D Digital Terrain Modeling & Civil Sitework Takeoffs
Earthwork estimating carries some of the highest financial risks in construction. An inaccurate cut/fill calculation can result in hundreds of thousands of dollars in unexpected off-site dirt export fees or imported select fill hauling costs.
At F&K Estimatings, our civil cost engineers build high-precision 3D digital surface terrain models from existing and proposed civil contour lines. We factor in topsoil strip depths, building pad subgrade requirements, soil shrink/swell indices from geotechnical reports, and structural paving cross-sections.
We provide complete line-item takeoffs for earthwork, underground utilities (storm, sanitary, water), paving, curbs, and erosion control to give you full bidding certainty.

Frequently Asked Questions
Do you calculate 3D cut and fill earthwork volumes?
Yes. We utilize 3D surface modeling software to calculate exact net cut and fill volumes, building digital terrain models from existing and proposed civil contour lines. We apply geotechnical soil shrink and swell factors based on site borings.
Can you estimate site utility pipe runs and underground structures?
Absolutely. We quantify all storm drainage, sanitary sewer, and domestic water distribution piping, along with precast manholes, catch basins, curb inlets, gate valves, and utility trench excavation/bedding volumes.
How do you handle site clearing, grubbing, and asphalt demolition?
Our sitework estimators calculate exact acreage for heavy tree clearing and grubbing, stripped topsoil volumes, and provide detailed square yardage and tonnage for existing asphalt, concrete curbs, and building demolition.
Do your sitework takeoffs include SWPPP erosion control?
Yes. We quantify silt fencing, construction exits, inlet protection bags, sediment basins, temporary hydroseeding, and straw wattles required for local environmental SWPPP compliance.
What is your typical turnaround for a sitework estimate?
Standard commercial site development packages are typically delivered within 48 to 72 hours. Large multi-acre subdivisions or commercial master-planned developments may require 4 to 5 business days for complete 3D surface modeling.
