Measurement & Deliverable Parameters
How are Berkshire 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 (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 | Berkshire County 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 Berkshire 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.
- Breaks down SWA sub-main runs using vertical riser heights plus floor horizontal cable-tray pathways and gland kits.
- Isolates fire-rated FP200/enhanced cabling for smoke vents, dry-riser interfaces, and evacuation alarms.
Which drawings and UK project types are supported?
- Lighting, small power & containment layouts
- Fire alarm, security & data ELV plans
- LV schematic & distribution board schedules

Electrical Estimating FAQs for Berkshire
What does a Berkshire electrical estimate include?
Every workbook provides net measured quantities in m, nr, circuits, sets, colour-coded PDF drawing mark-ups, separated material vs labour lines, and clarifications covering Berkshire site requirements.
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.
