Measurement & Deliverable Parameters
How are Devon county takeoffs audited and formatted?
| 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 Devon 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 | Severe wind-driven rain exposure specifies stainless fixings, heavy leadwork, and marine-grade powder coatings. |
| 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.

Which county conservation or planning details do you track across Devon?
Dartmoor/South Hams local stone facing, natural slate hung gables, and ecological landscape buffers. Every material schedule pairs net drawing quantities with explicit specification notes matching your architect's elevation and section details.
What file formats can builders in Devon upload for an estimate quote?
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.
