AI earthwork takeoff & cut/fill in minutes
Turn CAD and vector PDF civil plan sets into accurate 3D terrain models and cut/fill balance sheets in minutes — not days. Automated contour detection, DTM, stripping, subsidence, and strata adjustments with bridge-ready accuracy.
Key Features
Automated contour detection & DTM
Reads existing and proposed contours, spot elevations, breaklines → builds 3D digital terrain model without manual digitizing.
Stripping, subsidence & strata layers
Adjust topsoil stripping depth, rock strata, over-excavation. Real-time BCY vs loose vs compacted conversions.
Structural excavation & trench takeoff
Utility trenches, footing excavations, retaining walls — quantities push directly to heavy civil assemblies.
Evidence-backed balance sheets
Every cubic yard traces to sheet, contour interval, and DTM log — auditable cut/fill reports for owners.
Interactive Tool
Try the cut & fill calculator
High-intent estimators stay to test volumes — BCY, CCY, LCY, stripping, haul cost. For full DTM automation, see the standalone tools page.
BidSync AI — Earthwork Cut & Fill Estimator
Calculate bank cubic yards (BCY), compacted fill (CCY), and net volume balancing.
Need 3D Contour & DTM Earthwork Extraction?
Let BidSync AI automatically extract quantities directly from PDF civil plan sets.
Formula: (Area × Depth) ÷ 27 = CY • Stripping added to cut • Net = Cut BCY − Fill CCY • LCY = BCY × swell. For bid-ready DTM, see Earthwork Takeoff.
How BidSync AI Handles 3D Earthwork Takeoffs
Upload vector PDF/DWG → automated contour detection builds 3D DTM → adjust stripping/subsidence/strata → output BCY/CCY balance sheet to bid items. Handles 100+ sheets via Cloudflare Edge rendering.
How to calculate cut and fill volumes automatically?
DTM built from plans, auto-adjusted for stripping/compaction, exports BCY/CCY balance to bid.
What is BCY vs CCY?
BCY = bank (in-situ), CCY = after compaction. BidSync converts with shrinkage factors per soils report.
