Measurement & Deliverable Parameters
How are Liverpool doors & windows packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 24 & 25 (Doors, Windows & Curtain Walling) measured in nr, m2, m, sets | 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 | Liverpool 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 Liverpool pack?
Nothing derails a fenestration or fit-out bid faster than mismatched architectural window schedules and plan openings. We reconcile every opening—PPC aluminium frames, composite heritage casements, structural glass roofs, automatic entrance doors, and FD30S/FD60S fire doorsets.
- Cross-checks structural opening width/height against elevation drawings and highlights conflicts in an RFI tab.
- Distinguishes Part Q laminated security glass, acoustic attenuation dB units, and obscure bathroom glazing.

Port-adjacent steelwork/industrial haulage paired with city-centre Georgian Quarter conservation refurbishment constraints. Alongside Cross-checks structural opening width/height against elevation drawings and highlights conflicts in an RFI tab. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Which file formats can Liverpool contractors upload for a doors & windows quote?
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every doors & windows estimating pack returns editable Excel schedules and marked-up PDF sheets.
Do you check if window schedules match what is actually drawn on plans and elevations?
Yes. Discrepancies in opening counts, handing (LH/RH), fire escapes, or U-values/acoustic specs are flagged immediately on our discrepancy log.
