Question

What will be an ideal response?

Answer 1

The following can be extracted from the model:



The following electrical components are needed:



19 ea single-pole switches

10 ea three-way switches

15 ea phone jacks

2 ea phone jacks – floor mount

79 ea duplex outlets

2 ea duplex outlets – floor mount

3 ea GFI duplex outlets

2 ea GFI duplex outlets with weatherproof covers for use outside

83 ea 2-foot by 2-foot fluorescent light fixtures

6 ea can light fixtures

3 ea surface-mount light fixtures

1 ea panel



Allowing eight lights or outlets per circuit, 23 each 20-amp circuits will be needed, plus circuits for the heat and cooling system (allow a 40-amp circuit) and the water heater (allow a 30-amp circuit). Allow for one 30-space 225-amp panel and one 225-amp main breaker panel and one meter base.



The following approximate wiring quantities are needed. The quantities were measured in OnScreen Takeoff and will vary based upon which outlets are placed on which circuit:

322 ft 3-12 Romex

2,655 ft 2-12 Romex

756 ft phone wire

64 ft 4/0 wire and 32 ft #8 wire (connect panels)

100 ft #6 wire (heating)

30 ft #4 wire (water heater)
