Shop Dwgs

Shop drawings are what the field install from. I'd think it's important to have a good engineer/CAD person in your company as they could either be wasteful with the design or very efficient. Make sense?

Also, do shop that the electrical contractor produces for the field usually show all the branch conduits/cables....down to the level of detail?

Show drawings for conduit runs typically show elevations, number of conduits on the rack, pull boxes, etc. On large jobs there is more and more use of 3D models required by the GC for all of the trades so there are no conflicts. If that's required you'll have no choice but to hire a skilled engineer to provide that info to the GC. Back in the day we (meaning foreman and sub-foreman) made our own conduit drawings. We would take the shop drawing from the tin knocker and the sprinkler fitter and design our layout around theirs.

I agree with Rob. Like it or not BIM is here to stay. The company I worked for had three or four BIM people. Before that we would have to contract one.

Ohhh, shop drawings. I thought it was about shop dogs.

I think an architect or engineer should have field experience, and should visit the job-site if it exists yet.

Job we have. Job we have now is a 2d job not bim(3d).

You could wind up being very disappointed. BIM is an entirely different animal from CAD. In fact, having a CAD background can slow you down if you have to pivot to BIM. You want an experienced BIM operator with an engineer to feed him/her the 2-D sheets with the layout info.

When I made the transition from semiconductors to renewable energy I spent the first couple of months working as a rooftop PV installer. For my first commercial PV project (~650kW) I was the on site QC engineer, and I did site surveys for that company and every other company I worked for. Field experience is a very valuable adjunct to systems design engineering.
