Sorry I didn't realize all the variables.

Is it all in conduit, wiremold? NO
Are you dealing with a 200 year old NYC building ? NO
Is it newer construction? 15 YEARS
Did you include a pathway system ? NO
If so what kind of pathway system ? NO
What quality of cable and hardware did you use ? BELDEN CAT6 - PANDUIT PATCH AND RJ-45
Does this include all the configuration of routers and switches? NO, JUST CABLE, CABINET, PATCH PANEL, AND TERMINATE EACH END.
Were all the runs at maximum length or were they all 50' runs ? 50' TO 90'AVG.
How many cables are we talking here? 24
Were they all single location or quad drops ? SINGLE
How did you certify the job ? BORROWED A FLUKE CERTIFIER (man that thing is intense!)
Any pics of this project ? NO. IMAGINE A DOCTORS OFFICE WITH A DROPPED CEILING. HAD TO DO IT AFTER HOURS.

THE THING THAT TOOK SO LONG WAS THAT THE TRUSSES WERE 8' ABOVE THE GRID, AND THERE WAS ROMEX ALL OVER THE PLACE SECURED TO TIE WIRE A FEW INCHES ABOVE THE GRID. STEEL STUD WALLS. WE PUT THE CABLE UP ON THE TRUSSES TO GET IT AWAY FROM ALL THAT ROMEX, AND LAY IN LIGHTS.
