Earthwork Estimating for Devon Construction Tenders
Serving builders, specialist subcontractors, and developers working throughout Devon, our earthwork estimating service delivers transparent NRM2 Section 5 (Excavating & Filling) bills of quantities calibrated around exposed coastal contemporary homes, rural cob/stone barn adaptations, holiday schemes, and exeter science/industrial sheds.

Measurement & Deliverable Parameters
How are Devon earthwork packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 5 (Excavating & Filling) measured in m3, t, m2, loads | Scaled GA plans at 1:50 / 1:100 or structural details in mm |
| Local Statutory Framework | Building Regulations (Approved Documents Parts A–S) & Building Safety Act (BSA) Gateways 1–3 | England statutory & local tender compliance notes |
| Wastage & Prelim Separation | Net quantities isolated with 5%–10% typical trade waste allowances | Devon County logistics and phased delivery allowances |
| Deliverables & Drawing Uploads | 100% open-formula Excel BoQ + colour-coded PDF overlays (up to 25 MB upload) | 24–48 hrs turnaround target for focused single-trade packages |
Calibration note: 1:50 and 1:100 architectural and structural drawings are scaled to 25 mm masonry tolerances and 100 mm thermal zones, isolating 5 percent to 10 percent wastage from net quantities.
What is measured in every Devon pack?
On sloped UK plots and former industrial estates, earthworks carry immense commercial risk. Comparing existing topographic contours against proposed formation levels, we quantify topsoil strips, cut-and-fill balances, haulage loads, and MOT Type 1 / 6F2 engineered capping layers.
- Separates inert, non-hazardous, and contaminated spoil horizons where borehole/WAC logs are provided.
- Applies appropriate UK soil bulking factors so haulage wagon counts are realistic, not theoretical net bank volumes.
Which drawings and UK project types are supported?
- Topographical survey with spot levels/contours
- Proposed finished floor & external levels
- Site investigation (SI) / WAC soil test summary

Earthwork Estimating FAQs for Devon
What does a Devon earthwork estimate include?
Every workbook provides net measured quantities in m3, t, m2, loads, colour-coded PDF drawing mark-ups, separated material vs labour lines, and clarifications covering Devon site requirements.
Can you convert net bank cubic metres into estimated lorry loads?
Yes. We state bank volume alongside bulked volume using rock/clay/granular bulking factors so muck-away haulage costs reflect reality.
Do you account for tree root protection zones and topsoil stockpiling?
Yes. Separate zones for topsoil strip, on-site bund storage, and re-spread onto landscaped areas are tracked explicitly.
