I'd like your opinions on the job I just lost to another licensed contractor.

The job consisted of an add on addition.
The following is all new wire.

2 bedrooms consisting of 14 outlets, 4 circuits-2 lighting, 2 recp., install 2 ceiling fans (provided by homeowner), both controlled by 1 single pole switch

one 20 amp laundry circuit, one 15 amp circuit for lighting ( 1 floresent)controlled by 2 three way switches

1 hallway recp, 1 ceiling light controlled by 2 three way switches-(using circuit feeding laundry room light)

one 15 amp circuit for 4 reg smoke detectors, 1 smoke/co2 detector

The contractor that got the job estimated $1500 less!!!!

Did I over bid?
