Measurement & Deliverable Parameters
How are BT1 (Belfast City Centre & Laganside) concrete packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 11 (In-Situ & Precast Concrete) measured in m3, m2, m, nr | Scaled GA plans at 1:50 / 1:100 or structural details in mm |
| Local Statutory Framework | Building Regulations (Northern Ireland) Technical Booklets | Northern Ireland statutory & local tender compliance notes |
| Wastage & Prelim Separation | Net quantities isolated with 5%–10% typical trade waste allowances | BT1 Postcode District 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 BT1 (Belfast City Centre & Laganside) pack?
Concrete contractors require far more than raw slab volume—true tender cost depends on formwork repetition, pour heights, kicker height, waterstops in basements, pump reach, and surface finish classes. Every NRM2 Section 11 variable is separated cleanly.
- Concrete volumes split cleanly by BS 8500 concrete class and sulfate exposure design.
- Edge formwork, soffit shuttering (>3.5m prop height noted separately), and architectural fair-faced concrete areas are isolated.
Which drawings and UK project types are supported?
- Foundation & slab plans
- Structural column/wall/stair core sections
- Pour sequence & construction joint specs

Concrete Estimating FAQs for BT1 (Belfast City Centre & Laganside)
Why do BT1 tenders require separate prelims & phasing clarity for concrete?
Soft estuarine Sleech clay requiring piled substructures alongside central Belfast arterial access planning. Separating physical net BoQ items from phased call-offs and urban logistics lets contractors price risk transparently without diluting trade rates.
Do you separate concrete blinding, structural pours, and screed toppings?
Yes. 50mm–75mm lean-mix blinding, DPM/vapour barriers, structural slab pours, and sand-cement or flowing screeds are itemised on separate lines.
Do you measure formwork for curved or battered concrete walls separately?
Yes. Straight vertical shuttering, battered formwork, curved walls, and boxed pockets/upstands are clearly differentiated.
