HVAC Estimating in Cambridge — NRM2 Section 38 (Ventilation & Comfort Cooling)
Our hvac estimating service for Cambridge projects translates architectural, structural, and engineering drawings into transparent NRM2 Section 38 (Ventilation & Comfort Cooling) schedules. Whether tendering across East of England under JCT or NEC procurement, every takeoff accounts for biomedical campus r&d labs, high-tech cleanrooms, university estate adaptations, and cambridge gault brick residential developments.

Measurement & Deliverable Parameters
How are Cambridge hvac & ventilation packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 38 (Ventilation & Comfort Cooling) measured in m, m2, 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 | Cambridge 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 Cambridge pack?
Ductwork and VRF contractors need clear visibility across duct dimensions, DW144 pressure classes, plenum boxes, smoke/fire dampers, and insulated refrigerant pairs. Our estimators break every air path from AHU intake louvre to room diffuser.
- Converts rectangular duct widths/heights cleanly into sheet-metal surface area (m2) alongside linear metres for DW144 pricing.
- Captures fire-rated ductwork sections, intumescent compartment dampers, and Part O / overheating cooling plant cleanly.
Which drawings and UK project types are supported?
- Ventilation & air-conditioning floor layouts
- Ductwork sizing, damper & grille schedules
- VRF branch selector & refrigerant schematics

HVAC & Ventilation Estimating FAQs for Cambridge
How does Cambridge site context influence hvac estimating takeoffs?
Cycle/pedestrian priority city core limits heavy goods access windows during term time. Alongside Converts rectangular duct widths/heights cleanly into sheet-metal surface area (m2) alongside linear metres for DW144 pricing. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Which file formats can Cambridge contractors upload for a hvac & ventilation quote?
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every hvac estimating pack returns editable Excel schedules and marked-up PDF sheets.
Do ductwork takeoffs measure fittings/bends/reducers or linear metres with fitting factors?
Either format—we provide exact linear lengths per duct dimension plus surface area (m2) and counted transitions, plenums, bends, and attenuators.
