South East England · England · NRM2 Sections 33–36 (Roads, Drainage & Utilities)
Serving builders, specialist subcontractors, and developers working throughout Buckinghamshire, our sitework estimating service delivers transparent NRM2 Sections 33–36 (Roads, Drainage & Utilities) bills of quantities calibrated around high-volume milton keynes redway housing parcels, amersham and beaconsfield bespoke detached residences, barn conversions in vale villages, and hs2-corridor commercial compounds.
Local Engineering Context
Steep Chilterns Chalk Escarpment above High Wycombe contrasting with shrinkage-prone Aylesbury Vale Gault Clay and Oxford Clay requiring stepped strip footings or trench-fill concrete.
Local Engineering Context
Chilterns National Landscape knapped-flint and red-brick bonding schedules, natural clay plain roof tiles, and Buckinghamshire Council biodiversity net-gain external works.
Local Engineering Context
Phased Milton Keynes grid-road bulk muck-away logistics versus single-track Chiltern chalk hills requiring mini-rig piling, split-load concrete deliveries, and hedge protection.
Measurement & Deliverable Parameters
| 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 | Buckinghamshire 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.
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.
Every workbook provides net measured quantities in m, m2, m3, nr, colour-coded PDF drawing mark-ups, separated material vs labour lines, and clarifications covering Buckinghamshire site requirements.
Yes. Adoptable Type A/B manholes, clay/twinwall pipes, and public connections are split cleanly from private plot gullies and ACO channels.
Yes. Tactile blister flags, transition kerbs, thermoplastic white lining, bollards, and lighting duct/base pits are measured completely.
