Measurement & Deliverable Parameters
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 11 (In-Situ & Precast Concrete) measured in m3, m2, m, nr | 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 | Somerset 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.
Concrete contractors require far more than raw slab volume—true tender cost depends on formwork repetition, pour heights, kicker height, waterstops in basements, pump reach, and surface finish classes. Every NRM2 Section 11 variable is separated cleanly.
Every workbook provides net measured quantities in m3, m2, m, nr, colour-coded PDF drawing mark-ups, separated material vs labour lines, and clarifications covering Somerset site requirements.
Yes. 50mm–75mm lean-mix blinding, DPM/vapour barriers, structural slab pours, and sand-cement or flowing screeds are itemised on separate lines.
Yes. Straight vertical shuttering, battered formwork, curved walls, and boxed pockets/upstands are clearly differentiated.
