Bid Civil Sitework with Confidence on Every Cut, Fill, and Pipe Run

Civil sitework and utility takeoff requires meticulous attention to pipe slope profiles, structure depths, paving cross-sections, and clearing boundaries. Missing 500 feet of 18-inch storm drain or miscalculating stone base tonnage can turn a profitable site project upside down. Smart Scale Estimators provides contractors with an experienced civil estimating team that extracts exact quantities from complex civil engineering sets.

  • Detailed utility schedules showing pipe size, trench depths, and structures
  • Stone base and asphalt tonnage calculated with accurate compaction factors
  • Separates onsite utility scope from offsite street connection right-of-way work
  • Seamless coordination with our concrete estimating desk for curbs and flatwork

ESTIMATING WORKFLOW

How we produce your trade estimate.

01

Civil Drawing & Geotechnical Ingestion

We review existing and proposed contour sheets, grading plans, utility profiles, and erosion control drawings.

02

Surface Area & Demolition Quantification

We measure site clearing boundaries, pavement removals, topsoil stripping areas, and erosion control perimeters.

03

Utility Profile & Trench Measurement

We trace storm, sanitary, and water runs, calculating pipe lengths, bedding gravel volume, trench safety shoring, and structure counts.

04

Paving & Base Course Compilation

We calculate stone base tonnage, asphalt binder/wear tonnage, and curb lengths, compiling the complete civil estimate package.

TRADE FAQS

Common questions for sitework & earthwork estimating.

Details on unit pricing, measurement standards, software compatibility, and plan revision turnarounds.

Working with a dedicated sitework estimator allows civil and excavation contractors to bid multiple commercial and subdivision packages simultaneously without hiring full-time in-house engineering staff. Our civil takeoff specialists accurately calculate cut/fill earthwork volumes, pipe profiles, and paving tonnages within 24 to 48 hours.

Yes. Based on pipe diameter, trench depth, and specified bedding details (e.g. #57 stone bedding and structural backfill), we calculate bedding cubic yards and trench spoil volume.

Yes. We break down site packages into clear sub-tabs (on-site development vs. off-site road widening or municipal tie-ins) so you can bid them independently if required by the owner.

We apply standard regional density factors (typically 110 lbs per square yard per inch of depth for asphalt, and 1.8 to 2.1 tons per cubic yard for compacted stone base) to deliver ready-to-order supplier tonnage.

Yes. We quantify silt fencing, check dams, tree protection, retention/detention pond excavation, rip-rap energy dissipators, and hydroseeding acreage.
