SE1 Access, Hoists & Logistics Constraints
Network Rail viaduct acoustic vibration zones, Borough Market congested lanes, and Thames groundwater basement controls.
Greater London · England · NRM2 Section 24 & 25 (Doors, Windows & Curtain Walling)
Tendering work within SE1 (Southwark, Bankside, London Bridge & Bermondsey) demands tight cost clarity before mobilising to site. Our doors & windows estimating schedules capture exact net NRM2 Section 24 & 25 (Doors, Windows & Curtain Walling) quantities while separating prelims and material handling considerations driven by mixed-use rail-arch hospitality, contemporary glass commercial offices, life-science suites, and riverside apartments.

Measurement & Deliverable Parameters
| 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 | SE1 Postcode District 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.
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.
Network Rail viaduct acoustic vibration zones, Borough Market congested lanes, and Thames groundwater basement controls. Separating physical net BoQ items from phased call-offs and urban logistics lets contractors price risk transparently without diluting trade rates.
Yes. Discrepancies in opening counts, handing (LH/RH), fire escapes, or U-values/acoustic specs are flagged immediately on our discrepancy log.
Yes. Cill projections, head closers, perimeter EPDM weather-sealing, and acoustic mastic are itemised cleanly.
