Measurement & Deliverable Parameters
How are Somerset sitework & civils packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Sections 33–36 (Roads, Drainage & Utilities) measured in m, m2, m3, 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.
What is measured in every Somerset pack?
Civil external works frequently hold the largest hidden contingencies on UK residential and commercial developments. Cross-referencing engineering drainage longs and road sections, we measure pipe invert depths, precast concrete manholes, interceptors, SuDS geocellular crates, binder/surface asphalt courses, and street lighting.
- Reads invert and cover levels off manhole schedules to compute accurate excavation depth bands and surround concrete.
- Separates adoptable highway S278 off-site junction works from private internal estate roads.
Which drawings and UK project types are supported?
- Foul & surface water drainage layouts & long sections
- Roadways S38/S278 alignment & construction details
- Statutory utility (electric/water/fibre) duct layouts

Do sitework drainage schedules separate Adoptable Sewers (SfA) from private plot drainage?
Yes. Adoptable Type A/B manholes, clay/twinwall pipes, and public connections are split cleanly from private plot gullies and ACO channels.
Are tactile paving, dropped kerbs, road markings, and street lighting columns included?
Yes. Tactile blister flags, transition kerbs, thermoplastic white lining, bollards, and lighting duct/base pits are measured completely.
