Civil Engineering Cost Calculator.
Pick your project type and site conditions. Get a typical 2026 fee range in one click. Built from real project pricing by a licensed PE. No signup, no email required.
Typical U.S. range for this project type. Your city and watershed review set the final scope.
These are typical 2026 industry ranges, not quotes. Surveys, soils work, and wetland delineation are separate. See the full fee guide for what drives the number.

Calculator questions.
How accurate is this civil engineering cost calculator?
It returns typical 2026 U.S. fee ranges for each project type, adjusted for stormwater complexity. It is a budgeting tool, not a quote. Real fees depend on the specific site, jurisdiction, and scope. For a real number, send the site details and get a fixed-fee estimate from a licensed PE.
What does a civil engineering fee include?
A typical fixed fee covers the site plan, grading and drainage design, stormwater management plan, utility plan, erosion control and SWPPP, a stamped plan set, agency coordination, and permit submittal support. Surveys, geotechnical work, wetland delineation, and construction-phase services are usually separate.
Is there a land development cost calculator for total project cost?
This calculator covers the civil engineering design fee. Total land development cost also includes the land, survey, soils work, permits and fees, and construction. Engineering design typically runs 5 to 15 percent of site construction cost on small projects, falling to 2 to 8 percent on larger ones.
Why does stormwater change the cost so much?
Stormwater is usually the single biggest fee variable. A site needing a simple basin and SWPPP costs a fraction of one needing modeled detention, infiltration, and water-quality treatment for a demanding watershed district. The same building on two different sites can carry very different engineering effort.
