Hi friends,

One of our clients is setting up a factory and has contracted us for
the LAN cabling work which includes data (copper and fiber) and voice.

However, when I had a site visit, I see that the factory is not even
25% ready and is still only in construction.

I need to lay copper and fiber underground (inter-building) as well as
across the ceiling (intra-building). I only see 3 out of 23 blocks in
the factory completely ready. The others are still being constructed.
Some of them don't have ceilings and walls too. I am not sure when
exactly is the best time to start work in the factory.

I dont know if it is better to do cabling during the construction of
the building or it is better to do the cabling once all the
construction work has been done.

I feel right now left in the dark as there is no clear picture that I
see on how to move forward on this.

Looking forward to your earnest guidance on moving forward.


Tanks a lot
Gautam

If you've never worked on a multi-prime construction site before (you're
a prime since you don't work for the general contractor) you'd better
stay way back and just make sure the construction is done to the specs
you need. Pulling cable and wiring jacks is a much simpler universe that
working on a major construction site in terms of insurance, laws,
unions, coordination, etc... Oh, did a say multi-prime?

You do it during construction, since that is when you contracted to
do the work. Find the prime contractor and work out scheduling with
them. I'm surprised that you were not contracted to work by the prime
contractor.

I would wait until at least the ceiling gridwork is up or before. If you do
it before you have time to put in support members (J hooks, etc) for the
cabling. If there are beams, use beam clamps to support the cabling.

I personally wouldnt start until most of the contractors are out of there
except for the electricians, floor guys, and ceiling guys...

I would start the underground OSP stuff now. Go rent a ditch witch, lay your
schedule 80, and do your core drilling now. That is the ball buster of the
whole job anyhow....make sure you DO NOT PUT any 90 degrees in your OSP
conduit. Trust me....LOL Use 45 degree angles. Also, make sure when you
build out the conduit, to make sure your put your pull string in and please
make sure the string doesnt stick to the PVC cement!!!!!! Or you'll be
sorry...

In my experience, the best time to wire is AFTER the electrical guys,
but BEFORE the drywallers. First thing I'd do is work with the General
Contractor to find out who the Electrical Contractor is, and to work
with both of them on a schedule. The larger jobs I've done entailed us
"following" the electricians from space to space. For example, most of
the time they will start at one end of a floor of a building, and work
towards the other. As they go, you follow. I tried to stay about 2 days
behind them.

You may need a low-voltage wiring permit, depending on your location,
and you will probably be inspected on either your permit, or the
electrical permit, before the drywall's up. Again, work this out with
the General and the Electrical contractors. Most inspectors are going
to freak at doing a closed-wall inspection in new construction, and you
don't want the job red-tagged because you screwed this up. Life is much
easier if you just dovetail your work, and your inspection, with the
electrical guys.

I always bidded out this work at a cheaper rate than when I was doing
closed-wall because it's much less labor intensive. If you bid this out
full-rate, good for you! There should be lots of gravy :)

Good luck!
