Masonry Estimating in Portsmouth — NRM2 Section 14 (Masonry)
Our masonry estimating service for Portsmouth projects translates architectural, structural, and engineering drawings into transparent NRM2 Section 14 (Masonry) schedules. Whether tendering across South East England under JCT or NEC procurement, every takeoff accounts for island-city dense brownfield housing/pbsa schemes, naval heritage dockyard stonework refurbishments, marine engineering sheds, and extensions.

Measurement & Deliverable Parameters
How are Portsmouth masonry packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 14 (Masonry) measured in m2, nr, m, tonnes | Scaled GA plans at 1:50 / 1:100 or structural details in mm |
| 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 | Portsmouth 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.
What is measured in every Portsmouth pack?
UK brickwork packages demand exact opening deductions, reveal return closures, stepped cavity trays at roof abutments, windposts, and fire-rated movement joints. We convert wall elevations and sections into clean masonry subcontractor and merchant schedules.
- Uses standard UK metric modular brick counts (60 bricks/m2 single leaf with mortar joints) and 10 blocks/m2 per 100mm/140mm/215mm leaf.
- Quantifies curved arches, perforated hit-and-miss screens, soldier courses, and stone cills separately as labour extras.
Which drawings and UK project types are supported?
- Architectural elevations & floor plans
- Wall section build-ups & cavity details
- Structural lintel & windpost schedules

Masonry Estimating FAQs for Portsmouth
How does Portsmouth site context influence masonry estimating takeoffs?
Tight Victorian terrace plots on Portsea Island limit skip/scaffold footprints and require clean urban waste management. Alongside Uses standard UK metric modular brick counts (60 bricks/m2 single leaf with mortar joints) and 10 blocks/m2 per 100mm/140mm/215mm leaf. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Which file formats can Portsmouth contractors upload for a masonry quote?
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every masonry estimating pack returns editable Excel schedules and marked-up PDF sheets.
Do masonry takeoffs include masonry support angles, windposts, and wall starters?
Yes. Multi-storey stainless-steel masonry support angles, windposts, head restraints, and wall starters shown on structural details are counted cleanly.
