Please log in for more thread options 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 | |||||||||||||

Please log in for more thread options 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? | |||||||||||||

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... gautamzone@gmail.com says... >

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! | |||||||||||||
