Low-voltage still gets treated like a punch-list item on a lot of commercial builds in Abilene. Framing has a date. Electrical has a date. Insulation and drywall have dates. The data, camera, access, and Wi-Fi cable is "the IT guy" until somebody notices there are no sleeves through the fire walls and no drops at the front desk.
That is late. Late means fishing finished walls, surface raceway the owner did not want, and a trim-out that can hold up the certificate of occupancy. Bring the low-voltage contractor in before the walls close. Device locations and pathway decisions belong in design, not on a walk-through the week the drywall shows up.
Where cabling sits in the sequence
Treat low-voltage as a rough-in trade, not a finish trade.
After framing is up and the electrician has roughed in, the low-voltage crew pulls cable, sets boxes or mounting brackets, and sleeves penetrations. Electrical usually goes first because line voltage owns the stud bay and the panel. Low-voltage follows in the remaining space, kept separated from power as code requires. Insulation and drywall come after those pulls are in and photographed.
If the building needs conduit under the slab for a floor box or a conference table, that decision happens before the pour. Miss it and you are core drilling or cutting a trench later.
On a metal building, run tray or strut along the structure and drop cable for cameras and APs before the liner or insulation goes up. Once the blanket is in, fishing a camera drop to a corner of the eave is slow work.
Trim-out is a separate visit. Jacks, plates, patch panels, cameras, access points, and door hardware land after paint.
What we need from you at rough-in
A cable crew cannot invent the design on site and still hit your schedule.
Plate and device locations. Data jacks, AP mounts, camera positions, door readers, intercoms, and conference-room drops, marked on a floor plan even if model numbers are still TBD. "We'll figure out cameras later" is how you get a blank wall where the reception camera should have been.
Sleeves through rated walls and floors. Low-voltage still has to cross fire-rated assemblies. Sleeves installed and firestopped with a listed system at rough-in beat opening a finished IDF wall after the fire marshal walks. Who owns the sleeve, electrical, low-voltage, or the GC, needs to be agreed out loud, not assumed.
Back boxes and pathways at doors. Access control is the one that blows up at punch list. The strike or lock, power transfer, and reader each need a path in the frame or the wall. Coordinate with the door hardware package before the frames are set.
Power and space at the closet. A dedicated circuit, a ground, and room for a rack. A converted janitor closet with no cooling will take the cable, then cook the switch.
A walk with the superintendent before insulation. Confirm plate heights, AP locations against the reflected ceiling plan, and camera aim, so the drop does not end up 6 inches from the only usable mounting point.
What late costs
After drywall, every missed drop is a cut, a fish, a patch, and paint. In a finished lobby that is a schedule problem as much as a labor problem. In a rated corridor it is also a firestop problem, because the new hole has to be sealed again with a listed system.
Surface raceway is the fallback when nobody wants to open walls, and it looks like a retrofit in a building that was supposed to be new.
Missed sleeves through a fire wall mean the cable either does not reach the IDF or gets pushed through an unsealed penetration that will fail inspection.
Door hardware is the other late trap. If the low-voltage contractor first sees the opening after the frame is set and the door is hung, adding a reader, a strike, and a request-to-exit device can mean field work on a rated door or swapping hardware. That is a hardware change order, not a cable change order.
Put it on the schedule like a real trade
Bring the low-voltage contractor in at design development or early construction documents, not at substantial completion. Approximate device counts at DD beat exact counts after drywall.
Put rough-in on the 3-week lookahead after electrical rough and before insulation. Put trim-out after paint, with door hardware coordination as its own line, because that one depends on the hollow metal supplier and the hardware installer.
Send the floor plan, the reflected ceiling plan, the door schedule, and the fire-rated wall locations. That set is enough to pull cable without guessing.
Hold the walls open until the pulls are in and the sleeves are sealed. Closing up to stay on the drywall date, then calling for cable, is how you end up fishing walls.
