Structural, Site, and Civil Trades
Sitework and Excavation Estimating Services
Tribuild produces earthwork and sitework takeoffs from the civil documents: cut and fill balanced against existing and proposed grades, with stripping, aggregate, trenching, and erosion control quantified so your dirt bid is built on real volumes, not assumptions.
Dirt bids are won on the cut/fill balance. Tribuild builds earthwork takeoffs from the civil documents, existing and proposed surfaces compared to produce cut, fill, and a real import/export number after stripping and structural allowances, so your team isn't pricing dirt on a guess.
Stripping, aggregate base, trenching, erosion control, and site demolition are all quantified as their own lines, and every deliverable ships with documented assumptions and qualification notes (including the subsurface risk that stays with the contractor) your team can price and defend.
What we estimate for sitework and excavation
Clearing and grubbing
Site clearing and grubbing by area from the existing-conditions plan.
Stripping
Topsoil stripping by area and depth with stockpile/respread noted.
Excavation
Mass and structural excavation by volume from surface comparison.
Cut and fill
Balanced cut/fill volumes from existing vs. proposed grade surfaces.
Grading
Rough and fine grading by area to the finished grades.
Backfill
Structural and trench backfill by volume with compaction noted.
Aggregate base
Aggregate base course by area and depth under pavements and slabs.
Trenching
Utility trenching by linear foot and volume by depth.
Dewatering
Dewatering allowances where groundwater conditions are indicated.
Erosion control
Silt fence, inlet protection, and SWPPP measures by linear foot and unit.
Retaining conditions
Shoring and retaining coordination noted where shown.
Site demolition
Demolition of existing pavement, structures, and utilities by area and unit.
Haul-off, import and export
Off-haul and import/export quantities derived from the cut/fill balance.

Frequently asked questions
Civil grading plans with existing and proposed contours (or surfaces), geotech recommendations, pavement/aggregate sections, and utility plans. These let us build surfaces and balance cut and fill.
Yes, import and export are derived from the cut/fill balance after stripping and structural allowances, not assumed.
Yes. We build surfaces from PDF contours or provided CAD surfaces; quality improves with digital surface data where available.
Yes, SWPPP measures by linear foot/unit and demolition of existing pavement, structures, and utilities by area and unit.
