| 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 | Surrey County logistics and phased delivery allowances |

What is measured in every Surrey 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.
