Insulation or Electrical 1st?

[crooklyn]

I would like to Insulate my shop/garage before I run electrical and gas due to inspections and timing.
I was thinking of predrilling all the electrical runs so that after I insulate I can just run the cable and gas line.

Whats your opinion?

Electrical and gas first. You're just causing more work since you will be moving the insulation around to run your wire.

 

[machsnell]

no brainer you should definitely run electric and gas first. Inspector wants to see it all if you are getting inspections.

Electrical first.

So you want to insulate,have that inspected(required in most parts of BC) then remove all the insulation,wire your shop and have an electrical inspection,then put all the insulation back again?Must be nice to have so much spare time...

That would be an awful lot of extra work!

Have u ever watched a remodel show on HGTV and seen them insulate before the plumber and electrician did their work?

No of course not! Go in order and save yourself extra unnecessary labor!

The proper sequence is to rough in Mechanical and Electrical trades prior to insulation.

While it is technically possible to do it out of sequence you aren't saving yourself any time and in fact you may have to pull all of the insulation out if you catch the wrong inspector.

**** it up and do the rough ins now.

I do ducts and hard pipe then electric. Wires are easy to route around ducts and pipes, ducts and pipes are hard to route around wires. Insulation comes after utilities with the exception of places such as behind a duct where it will be inaccessible after installation.

Thanks all for the input. I wasn't going to insulate then remove it to do electrical.
I will run my electrical then gas then insulate.
Thanks all

i must have been working nights when i posted
what i meant was that i wanted to pre drill all my runs, insulate, get the inspection on insulation then with the insulation installed run the electrical and gas. thought since i have the wholes pre drilled it would be easy but i'm going to do it the normal way electrical and gas then insulate.


thanks again

If you're running your gas in black pipe, I'd do it before the electrical. It's easier to work a wire around the pipe than the pipe around the wire.

This is the order we always used in commercial and residential work.

Rough carpenter builds structure.

HVAC installs ductwork.

Rough carpenter repairs structure damaged by HVAC.

Plumber runs supply and DWV.

Rough carpenter repairs structure damaged by plumber.

Electrician installs wiring.

Rough carpenter modifies structure because of customer change order.

Begin process again.

Then, after electrical rough inspection, insulation and drywall is installed.

Then plumber and electrician are called in to repair damage done by drywall installer.

Project is finished when construction exceeds destruction.

In one project we actually charged each trade for the repairs required, due to the damage they caused.

Bill, that's perfect. Plumbers with chainsaws and Sawzall's.

Bill- sounds about right on a number of jobs Ive been on. Makes you wonder how any of the trades make any money.

The worst Ive seen was a fire sprinkler company who cut out large sections of 2 x 12 floor joists because they were too lazy or cheap to use a right angle hole howg to drill the holes for their pipe. F'ing MORONS!!

Just saw this, and it reminded me of an electrician we worked with that had his apprentice cut a hole in a structural gusset of a steel overhead ceiling beam, to run his conduit through. The gusset was at least an inch thick, and took the apprentice 3 hole saws and several hours. Idiot. Obviously it should have been saddled under. Likely, the electrician was useless at making saddles, and was too embarrassed to tell his apprentice. He was the **** of a lot of jokes after that, and to make matters worse, he ran a business on the outside.
