buitenhek, Thank you for the insightful response. Actually what prompted the submission was the fact that I ran into the car dealer method last week. A subcontractor I was going to hire told me that he estimates all of his labor pricing based on the BOM. Similar to how a auto service shop...

It seems that the multitude of contributors to the cabling forum price there project based on a per drop price. Usually in the $100 to $150 a single drop for Cat5e plenum. I am guessing this is for around a 150’ run in a typical office environment. I am wondering what higher level metrics you...

I was wondering how everyone addresses the Use Tax issue that we run into on national cable projects or local cable projects? It seems to be quite a gray area determining real property from personal property on a cable install BOM and bidsheet and how to cover the costs of the use tax. The use...

Be careful when using pins 3,4,5,6 which is the standard pinout for say a 2 line phone. I have ran into problems with dividing 2 jacks this way and then finding out that the customer has a legacy AT&T switch that uses pins 1,2,3,6 just like ethernet. Always find out what kind of phone system...

I do channel work with subs all across the country. Skill level varies from sub to sub. In the past I have used 1 hour for a single, 1.5 for a dual, and 2 hours for a quad. I just took the DD102 RCDD course and found that my procedure came in on the high side. If anyone had a work sheet that...

I am using an Altronix power supply for my 12 cameras and it works great. It rack mounts. Call Altronix and let them know exactly how long your runs are and how much power you need at each camera and they will provide you with a solution. Good luck.

Has anyone come up with a solid quote rate when it comes to labor hours for singles, duals, quads? I am wondering what the average number of hours would be for each senario with termination on both ends and testing included. Thanks all!

How does that spring loaded contraption work? I would really like find a better way to pull through j hooks. Lately I have just been pulling all runs outiside of the j's then laying them in and dressing back after all the runs are completed.

Has anyone ever come up with a way to stop a second or third pull with the same pull string from winding around the first pull. It seems I can only get 3 before I need to pull a new string? I never feed string with the pull, only the cable. I also keep the bucket far to the front or side to keep...

I'm sure you already hooked it up, but it is the black/slate on the second amphenol (Aux) on the main cabinet.

Does anyone know what size UPS I should purchase to be able to keep the system up for around 15 min. I just want to be able to shut it down nicely. Thanks all.

For the smaller TR's without ladder rack, BICSI recommends the use of a figure 8 if you must coil the cable. Just don't put it in a circular loop. I've heard that it degrades the signal.

The time that I find the stagger method to be of most use is when pulling cables for modular furniture. If all the cable will be coming out of one location to feed the cubes it is very easy and helpful to stagger the drops. It will also save you in labor costs due to knowing which cables go...

All depends on the customer and your relationship. I know that that really doesn't answer you question but it also depends on the size of the job (is it a large project with a competitive bid battle?), do you have a long relationship with the client? Also, if you are pulling duals, triples of...

Sorry I've been working out of the office. I see a minor miscommunication grew into a debate. Reminds me of my girlfiend. Anyway let's clear the air. I am powering the cameras (trying) with distributed 12vdc over cat5 using leviton's residential type distribution block...
