Measurement & Deliverable Parameters
How are BT1 (Belfast City Centre & Laganside) electrical packages measured and delivered?
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Section & Units | NRM2 Section 39 (Electrical Engineering Services) measured in m, nr, circuits, sets | 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?

Electrical Estimating FAQs for BT1 (Belfast City Centre & Laganside)
Why do BT1 tenders require separate prelims & phasing clarity for electrical?
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 electrical takeoffs include cable tray, basket, conduit, and dado trunking lengths?
Yes. Cable management pathways are measured separately by width/gauge alongside drop rods and earthing continuity bonds.
Are DALI lighting controls, emergency exit signs, and PIR sensors counted individually?
Yes—each luminaire code (normal, emergency maintained/non-maintained, self-test), presence detector, and scene plate is counted cleanly.
