Substructure & Ground
How does Surrey geology affect substructures?
Bagshot Sands, Weald Clay, and North Downs Chalk pockets requiring clear drainage/soakaway feasibility splits.
South East England · England
High-value bespoke detached houses, basement cinema/pool excavations, oak-framed additions, and Guildford/Woking commercial suites.
Substructure & Ground
Bagshot Sands, Weald Clay, and North Downs Chalk pockets requiring clear drainage/soakaway feasibility splits.
Site Prelims & Freight
Strict Tree Preservation Orders (TPOs) & constrained residential estate roadways demand careful temporary ground-protection takeoffs.
Conservation & Fabric
Surrey Hills AONB natural limestone, handmade clay tiles, and high-spec architectural glazing suites.
Measurement & Deliverable Parameters
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Applicable Standards | Building Regulations (Approved Documents Parts A–S) & Building Safety Act (BSA) Gateways 1–3 | Applied alongside Surrey planning & material expectations |
| Drawing Scales & Units | 1:50 & 1:100 GA plans calibrated independently in mm, m, m2, m3 & t | Every line linked to drawing sheet reference and structural grid |
| Wastage & Prelim Split | 5%–10% typical trade waste isolated from net quantities | Strict Tree Preservation Orders (TPOs) & constrained residential estate roadways demand careful temporary ground-protection takeoffs. |
| Deliverable Format | 100% open-formula Excel + colour PDF check drawings (24–48 hr target small jobs) | Upload files up to 25 MB through our UK tender portal |
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.
County Procurement & Takeoffs
Projects throughout Surrey (South East England) fall under Building Regulations (Approved Documents Parts A–S) & Building Safety Act (BSA) Gateways 1–3. Predominantly JCT Design & Build 2016/2024 and JCT Standard Building Contracts in commercial/residential, alongside NEC4 Option A/B for infrastructure and public-sector frameworks. Our digital takeoffs supply contractors, developers, and specialist trade subbies with editable Excel Builders Quantities, separated waste factors, marked-up PDF drawing sets, and RFI schedules covering missing construction details.
Bagshot Sands, Weald Clay, and North Downs Chalk pockets requiring clear drainage/soakaway feasibility splits. Our schedules itemise trench widths, concrete grades, haulage spoil disposal, and shoring separately from standard superstructure works.
Surrey Hills AONB natural limestone, handmade clay tiles, and high-spec architectural glazing suites. Every material schedule pairs net drawing quantities with explicit specification notes matching your architect's elevation and section details.
Upload scaled PDF plans, DWG/DXF CAD files, Revit/IFC models, or NBS specifications (up to 25 MB per upload). Finished packs issue in open-formula Excel with colour-coded PDF overlays.
