Dear forum,
we are currently in the phase of obtaining offers for our construction project. We have received an electrical offer through the wooden house builder and I would appreciate your assessment. The question for me is: Is the offer OK or should we get more offers. The problem here is mainly that most companies are already quite booked up for 2017...

Um, you have one lamp outlet per room and then altogether 22???
=22 rooms?
Otherwise, I find it quite expensive, especially some surcharges. In wooden houses (I assume prefab house, not log house) no chasing is needed, meaning for one socket maybe 10-15.- material and a few minutes work, but over 50.- gross for that?
Maybe as a reference, we did the electrical work ourselves and spent about 7,500.- on materials.
But that included a satellite system for 8 connections, I think 12 network connections, (radio) dimmers, a larger 3-row Hager meter cabinet with 2 meter slots, 4 FIs and about 50-60 circuit breakers, a few more sockets, all cables 2.5mm² to the sockets, stainless steel intercom system with 2 indoor units, blinds as master-slave with central switch etc.
So roughly not less material.
Meaning the labor cost is about 13 k€.
Even at a labor rate of 80.- per hour, the electrician would have to be onsite full-time for a whole month, seems a bit much to me...
