NECA has a much higher unit for pulling a 4 pair cable without conduit as opposed to pulling in conduit. Why is this?? Because of the pull string in conduit? Thanks.
Imagine a drop cieling in an office space. How many cieling tiles do you have to
remove ? Desks, file cabinets, the secetary all in the way of your step ladder.
Now secure the cable with zip ties to hanger wire. Now do your pull in conduit.
I didn't look it up, but a swag would be that the task of pulling(not in conduit) takes into account labor for securing/fastening, whereas pulling(in conduit) that labor has been completed when the pipe was installed?
On enough commercial construction, by the time you are pulling in your Cat5 or other comm/data/alarm type of cabling, there are so many people, things, equipment and the like in the way that it can get quite difficult to do this job, and often the ceiling grids are already installed, and also each end still has to be pulled down to it's termination point, which has just been made inaccessible by the newly installed ductwork that wasn't supposed to be there, but was anyway because it couldn't go anywhere else because the plumbers and sprinkler guys blocked all other points.
sorry for the run-on sentence.
