Scotland (Central Belt & North East) · Scotland · NRM2 Sections 17–18 (Sheet & Tile/Slate Roofing)
Our roofing estimating service for Aberdeen projects translates architectural, structural, and engineering drawings into transparent NRM2 Sections 17–18 (Sheet & Tile/Slate Roofing) schedules. Whether tendering across Scotland (Central Belt & North East) under JCT or NEC procurement, every takeoff accounts for rubislaw granite civic refurbishments, altens and bridge of don energy-transition industrial workshops, and scottish building warrant residential schemes across aberdeenshire.
Local Engineering Context
Hard Aberdeen granite bedrock at shallow depths beside stiff glacial tills drives hydraulic pecker rock-breaking allowances, sulphate-resisting concrete pads, and reinforced yard aprons.
Local Engineering Context
Severe North Sea saline exposure mandates close-boarded 22mm Scottish roof sarking, A4 marine-grade 316 stainless slate hooks, triple-glazed alu-clad frames, and lime-mortar granite repointing. Scheduled in line with Building (Scotland) Regulations Technical Handbooks (Building Warrants).
Local Engineering Context
Haulage coordination up the A90 Corridor and harbourside cranage slots require exact off-the-plan cut-length schedules to prevent costly North East restocking delays.
Measurement & Deliverable Parameters
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Sections 17–18 (Sheet & Tile/Slate Roofing) measured in m2, m, nr | Scaled GA plans at 1:50 / 1:100 or structural details in mm |
| Local Statutory Framework | Building (Scotland) Regulations Technical Handbooks (Building Warrants) | Scotland statutory & local tender compliance notes |
| Wastage & Prelim Separation | Net quantities isolated with 5%–10% typical trade waste allowances | Aberdeen logistics and phased delivery allowances |
| Deliverables & Drawing Uploads | 100% open-formula Excel BoQ + colour-coded PDF overlays (up to 25 MB upload) | 24–48 hrs turnaround target for focused single-trade packages |
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.
UK weather leaves zero margin for missed flashings or under-counted valleys. Measuring pitched surfaces from roof plans and elevations, we account for eaves Overlaps, dry-fix ridges/hips, Lead/GRP valley troughs, parapet cappings, tapered PIR schemes, and rainwater goods.
Haulage coordination up the A90 Corridor and harbourside cranage slots require exact off-the-plan cut-length schedules to prevent costly North East restocking delays. Alongside Converts flat CAD plan footprints accurately using the true roof pitch angle before deducting lanterns or chimneys. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every roofing estimating pack returns editable Excel schedules and marked-up PDF sheets.
Yes. BS 5534 dry-fix ridge kits, mechanical tile clips, felt eaves trays, dry verges, and over-fascia vents are all itemised.
