Planning Your Cabling Infrastructure Before an Office Renovation

If your business is planning an office renovation, you have a window of opportunity that won't come around often: the chance to install or upgrade your cabling infrastructure while the walls are open. Miss this window and you'll be paying for surface-mounted conduit, disrupted ceilings, and patched drywall for years.

Why Cabling Needs to Come First

Cabling is one of the first trades to rough in and one of the last to finish. The cable runs need to be in the walls before the drywall goes up, but the terminations and testing happen after the space is finished. This means your cabling contractor needs to be involved in the project from the very beginning — not called in after the renovation is complete.

The most common and costly mistake we see is businesses that complete a renovation and then realize they don't have enough data drops, or that the drops are in the wrong locations, or that the cabling doesn't support the speeds they need. Fixing any of these problems after the fact means opening walls, running surface conduit, or living with a substandard solution.

What to Plan Before the Renovation Starts

Start with a floor plan and mark every location where you'll need a data connection: workstations, printers, IP phones, access points, security cameras, door access control panels, and any other networked devices. Add 20–30% more drops than you think you need — it's far cheaper to install extra drops during a renovation than to add them later.

Decide on your cable category. For most commercial renovations today, Cat6 is the right choice. If you're planning a server room or high-density area, consider Cat6A.

Plan your telecommunications room location carefully. It should be central to the floor plate, accessible, and large enough to accommodate your patch panels, switches, and any other active equipment. A room that's too small or poorly located will cause problems for the life of the building.

Coordinate With Your General Contractor

Your cabling contractor needs to coordinate with your general contractor on timing. Cable runs need to happen after framing but before insulation and drywall. Conduit sleeves through fire-rated walls need to be installed by the right trade at the right time. Getting this coordination wrong adds cost and delays.
