Wales (Cardiff, Swansea & Regional) · Wales · NRM2 Section 5 (Excavating & Filling)
Our earthwork estimating service for Swansea projects translates architectural, structural, and engineering drawings into transparent NRM2 Section 5 (Excavating & Filling) schedules. Whether tendering across Wales (Cardiff, Swansea & Regional) under JCT or NEC procurement, every takeoff accounts for copr bay waterfront commercial quarters, swansea university engineering estates, steep terraced south wales refurbishments, and gower peninsula custom housing.
Local Engineering Context
Former anthracite mine workings, pennant sandstone gradients, and mandatory Welsh SuDS SAB drainage require rotary-percussive coal grouting allowances, gabion retaining walls, and attenuation ponds.
Local Engineering Context
Direct Bristol Channel Atlantic gales in severe exposure Zone 4 require breathable silicone through-colour renders, double-nailed Welsh heather-blue slate, and enhanced lead valley gutters. Scheduled in line with Building Regulations (Wales) Approved Documents & Welsh SuDS SAB Mandatory Drainage Approval.
Local Engineering Context
Tight terraced hillside access in Uplands, Townhill, and Mumbles shapes grab-lorry spoil removal, pumped concrete boom reach, and scaffold bridging over public footways.
Measurement & Deliverable Parameters
| 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 (Wales) Approved Documents & Welsh SuDS SAB Mandatory Drainage Approval | Wales statutory & local tender compliance notes |
| Wastage & Prelim Separation | Net quantities isolated with 5%–10% typical trade waste allowances | Swansea 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.
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.
Tight terraced hillside access in Uplands, Townhill, and Mumbles shapes grab-lorry spoil removal, pumped concrete boom reach, and scaffold bridging over public footways. Alongside Separates inert, non-hazardous, and contaminated spoil horizons where borehole/WAC logs are provided. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every earthwork estimating pack returns editable Excel schedules and marked-up PDF sheets.
Yes. We state bank volume alongside bulked volume using rock/clay/granular bulking factors so muck-away haulage costs reflect reality.
