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 EC1 (Clerkenwell, Farringdon & Finsbury) 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 EC1 (Clerkenwell, Farringdon & Finsbury)

Why do EC1 tenders require separate prelims & phasing clarity for electrical?

City fringe out-of-hours crane/pit-lane bookings, strict Crossrail/Underground settlement proximity checks, and congested streets. 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.
