|---|---|---|
| District Compliance | High Thames water-table waterproofing paired with commercial HVAC & acoustic glazing. | Cross-referenced against London building control requirements |
| Drawing Calibration | 1:50 & 1:100 architectural/structural sheets in mm, m, m2, m3 & nr | Sheet-coded NRM2 line items for fast commercial audit |
| Logistics & Waste Split | 5%–10% standard waste allowance separated from net build items | Network Rail viaduct acoustic vibration zones, Borough Market congested lanes, and Thames groundwater basement controls. |
| Turnaround & File Transfer | 100% unlocked Excel + PDF markups · 25 MB upload limit per submission | 24–48 hr target turnaround on focused single-trade requests |
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.
Commercial Tender Deliverables
How do SE1 ground conditions shape the workbook format?
Shrinkable London Clay over Thames Terrace Gravels routinely drives deep piling, contiguous secant walls, and Grade 3 BS 8102 basement waterproofing. Governed by Building Regulations (Approved Documents Parts A–S) & Building Safety Act (BSA) Gateways 1–3, our estimating schedules for SE1 (Southwark, Bankside, London Bridge & Bermondsey) separate physical measured quantities under RICS NRM2 rules from urban logistics, loading-bay restrictions, and temporary protection allowances across open-formula Excel workbooks and colour-coded PDF verification drawings.
