Calculating cable quantities for housing estates
Housing estates need quantity discipline: metre estimates, contingency, and drum lengths that match installation crews—not guesswork on the dock.
From drawings to metres
Use circuit schedules or typical house takes-offs, then multiply by unit count.
Add contingency for waste, routing changes, and damage.
Drum strategy
Prefer drum lengths crews can handle on site; ultra-long drums may slow installation.
Separate lighting, power, and specialty circuits on the BOQ.
Ordering
Freeze quantities before production; late adds disrupt loading plans.
NMF helps translate estate BOQs into manufacturer drum schedules.
