Electrical Estimating in Belfast — NRM2 Section 39 (Electrical Engineering Services)
Our electrical estimating service for Belfast projects translates architectural, structural, and engineering drawings into transparent NRM2 Section 39 (Electrical Engineering Services) schedules. Whether tendering across Northern Ireland under JCT or NEC procurement, every takeoff accounts for titanic quarter commercial waterfront offices, cathedral-quarter hospitality refurbishments, student/btr blocks, and ni housing schemes.

Measurement & Deliverable Parameters
How are Belfast 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 | Belfast 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 Belfast pack?
Competitive UK electrical bidding demands point-by-point discipline across lighting controls (DALI/PIR), containment separation (power vs Cat6A), BS 5839 fire detection zones, access control, and 18th Edition BS 7671 protective switchgear. We provide ready-to-price Excel schedules built to ECA-style workflows.

Electrical Estimating FAQs for Belfast
How does Belfast site context influence electrical estimating takeoffs?
Irish Sea port haulage lead-times make early accurate Material Takeoffs (MTO) for structural steel and glazing frames essential. Alongside Breaks down SWA sub-main runs using vertical riser heights plus floor horizontal cable-tray pathways and gland kits. Our Excel workbooks separate measured quantities cleanly from site-specific prelim and access allowances.
Which file formats can Belfast contractors upload for a electrical quote?
Upload scaled PDFs, DWG/DXF CAD files, Revit/IFC BIM models, or NBS specifications directly via our online tender desk—every electrical estimating pack returns editable Excel schedules and marked-up PDF sheets.
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.
