Measurement & Deliverable Parameters
How are Cambridgeshire 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 | Cambridgeshire 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 Cambridgeshire 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 Cambridgeshire
What does a Cambridgeshire hvac & ventilation estimate include?
Every workbook provides net measured quantities in m, m2, nr, colour-coded PDF drawing mark-ups, separated material vs labour lines, and clarifications covering Cambridgeshire site requirements.
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.
Can you price residential MVHR semi-rigid radial ducting separately from rigid galvanised?
Yes. MVHR manifolds, radial 75mm pipe coils, roof cowls, and acoustic attenuators are scheduled specifically for Part F housing packages.
