Building (Scotland) Regulations Technical Handbooks (Building Warrants)
Independent construction estimating tailored to Scottish Building Warrant submissions, SBCC JCT forms, wet-dash masonry/timber-kit dwellings, and Highlands-to-Lowlands infrastructure.
Procurement & Contracts
SBCC (Scottish Building Contract Committee) variants dominate private commercial & housing contracts, while NEC4 Option A/B/C underpins major civil and renewables-adjacent works.
Weather & Technical Standards
Higher wind-driven rain exposure in west/northern Scotland increases reliance on heavy-sarked natural slate roofs, treated timber frame kits, zinc/standing seam weathering, and deep stone/granite ground-preparation allowances.
Measurement & Deliverable Parameters
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Regulatory System | Building (Scotland) Regulations Technical Handbooks (Building Warrants) | Applied to architectural & structural drawings across Scotland |
| Procurement Formats | JCT Design & Build, Traditional, SBCC & NEC4 schedules | Structured to RICS NRM1 / NRM2 in m2, m3, m, kg, and nr |
| Waste & Prelim Split | 5%–10% typical trade waste isolated from net build items | Allows contractors in every UK county to verify merchant & labour rates |
| Workbook & Turnaround | 100% open-formula Excel + 24–48 hr target for small residential packages | Supports drawing uploads up to 25 MB via encrypted quote 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.
Yes. Unlike open batten details more common in parts of southern England, Scottish pitched roof assemblies typically include 19mm/22mm sarking boards, counter-battens, and breather felt measured cleanly in m2.
Yes. All 32 trades can be issued in RICS NRM2 order or grouped to match SBCC and Scottish trade subcontractor packages.
