Sample Sitework Takeoffs & 3D Cut/Fill Heatmaps
We believe in 100% transparency. Below is an interactive sample package from a typical 12.4-acre commercial site development project, demonstrating our 3D terrain heatmaps, utility trench depth stratification, and itemized Excel takeoff formats.
What Makes Our Takeoff Package Ready for Bid Day
When you receive a takeoff from Sitework Estimate, there is no deciphering handwritten notes or reformatting messy spreadsheets. Every package comes organized to give you immediate commercial clarity:
Unlocked Formulas
All Excel cells contain transparent mathematical formulas (e.g. converting Area × Thickness × Density). You can change unit costs, labor rates, or material scrap allowances instantly.
Visual Verification Plans
You receive high-resolution marked-up PDF blueprints showing every digitized line and boundary contour, giving your field superintendents a visual reference during construction.
3D Machine Control Surface Exports
Need 3D surfaces for your GPS dozers and excavators? We export watertight TIN meshes to LandXML, Trimble (.ttm), and Topcon (.tn3) formatted directly to project subgrades.
Verified Pre-Bid QA/QC Audit
Every estimate undergoes our multi-point Takeoff QA/QC Audit checking zero-spikes, subgrade offsets, utility slopes, and unit conversions before delivery.
Detailed Breakdown of Takeoff Components
A professional civil takeoff is not a single number; it is an integrated engineering dataset. Below is how our core deliverables are structured and utilized by project teams.
1. The 3D Cut/Fill Elevation Color Heatmap
Our visual heatmaps bridge the gap between engineering calculations and jobsite operations. Rather than staring at dense contour lines, estimators and field superintendents immediately see:
- Deep Cut Zones (>4.0 ft): Red shading highlighting heavy excavation areas and mass cut pockets.
- Moderate Cut (1.0 to 4.0 ft): Amber shading indicating stripping and building pad rough cut.
- Neutral Grade (±0.5 ft): Green daylight boundary lines where proposed grade meets native terrain.
- Moderate Fill (1.0 to 4.0 ft): Cyan shading marking parking lot subgrade fill areas.
- Deep Structural Fill (>4.0 ft): Deep blue zones requiring engineered lifts and compaction testing.
2. The Multi-Tab CSI MasterFormat Excel Workbook
Our Excel deliverables are fully unlocked, dynamically linked, and formatted according to CSI divisions:
- Tab 1 — Executive Summary: Site acreage, gross cut, gross fill, net balance, topsoil strip/respread, and import/export totals in BCY, LCY, and CCY.
- Tab 2 — Earthwork Operations: Demolition, clearing/grubbing acreage, building pad undercuts, structural fill, and rock excavation strata.
- Tab 3 — Underground Utilities: Sanitary, storm, and water pipe runs stratified by trench depth (0-6', 6-10', 10'+) with bedding stone tons and backfill yardage.
- Tab 4 — Paving & Flatwork: Subgrade fine grading, aggregate base tons, asphalt wearing/binder courses, concrete curbs LF, and sidewalk SF.
3. Vector Color-Coded Plan Markups
Every line item in our Excel spreadsheet ties directly to a marked-up vector PDF plan sheet. We utilize standardized drafting layers:
- Red Polygons: Heavy cut areas and building pad excavation footprints.
- Blue Polygons: Embankment fill zones, stormwater retention ponds, and berm fills.
- Magenta & Cyan Polylines: Wet utility runs (storm, sanitary, waterline) showing exact pipe length, pipe diameter, and structure callouts.
- Green Boundaries: Pavement limits distinguishing heavy-duty truck paving from standard automobile parking.
4. Written Estimating Assumptions & Scope Qualifications
An estimate without written qualifications is an invitation to contract disputes. Every delivery includes an explicit narrative stating:
- Topsoil Stripping Depth: Explicit assumed stripping depth (e.g. 6 inches across all disturbed grading areas).
- Soil Conversion Factors: Geotechnical bank-to-loose swell factor and bank-to-compacted shrinkage factor applied.
- Pavement Subgrade Offsets: Exact pavement thickness deducted from the finished surface to reach rough subgrade.
- Trench Payline Widths: Pipe outer diameter plus OSHA minimum trench clearance used for excavation and stone bedding calculations.
Frequently Asked Questions About Deliverables
Can I insert my own unit labor, equipment, and material costs into the takeoff spreadsheet?
Yes, absolutely. Our Excel workbooks are delivered completely unlocked with zero password protection. Every quantity is organized with open unit-rate input columns. When you enter your local subcontractor or in-house unit rates ($/CY for excavation, $/TN for base stone, $/LF for pipe), the formulas automatically calculate totals, sub-totals, overhead, and profit markups.
What file formats will I receive in the final delivery package?
You receive a comprehensive digital package containing: (1) Unlocked Microsoft Excel (.xlsx) takeoff workbook, (2) High-resolution vector PDF plan markups with layer toggling, (3) 3D Cut/Fill Color Heatmap PDF and 3D PDF surface models, (4) Written Estimating Assumptions & Scope Audit Report, and (5) Optional LandXML / CAD surface export files for GPS machine control integration.
How do your deliverables help resolve addenda changes before bid closing?
Because our initial takeoffs are built on structured 3D terrain surfaces and vector layers, when an addendum or revision bulletin is issued, we perform a rapid digital overlay. We calculate the exact delta quantities (e.g., +450 CY cut due to lower building pad, or -120 LF sanitary sewer due to realigned easement), allowing you to adjust your bid pricing immediately without paying for a full re-takeoff.
How can general contractors verify these quantities during subcontractor scope leveling?
General contractors utilize our sample and custom takeoff packages during post-bid scope leveling sessions. When two excavation subcontractors submit wildly divergent earthwork numbers (for instance, one quoting 8,500 CY export and another quoting 14,200 CY export), our surface-to-surface volume report and visual heatmaps serve as the neutral, third-party benchmark. GCs can pinpoint whether a subcontractor neglected to deduct building pad slabs, miscalculated pavement subgrade depths, or failed to account for topsoil respread.
Can deliverables be formatted to trade-specific subcontractor bid scopes?
Yes. If you are a specialized grading contractor who does not perform underground utilities, or an underground utility contractor who excludes paving and curb concrete, we isolate your exact trade scopes. We generate standalone summaries isolating only the pay items, excavation depths, pipe lengths, and stone bedding volumes required for your specific subcontractor proposal.
