Structured cabling is rarely visible, but almost every connected system depends on it: computers and phones, Wi-Fi access points, cameras, access control, AV and building systems. It also tends to outlive the equipment connected to it. Decisions made before installation determine whether the network will be easy to operate and extend — or slow and risky to change.
Start from how the space will be used
Outlet positions should follow the final layout of desks, meeting rooms, reception, technical areas and ceilings — not the empty floor plan. Include the devices people forget: access points, cameras, displays, access readers and building controllers.
Plan pathways and capacity for growth
Cable trays, conduits and risers should have spare capacity. Adding cables later through full pathways is expensive and disruptive. The same applies to patch panels and rack space.
Choose copper or fiber per link
Horizontal cabling to work areas is typically copper. Backbones between floors, buildings or distant technical rooms often call for fiber because of distance and capacity. The right answer depends on each link — a mixed design is normal.
Design the telecom rooms and racks
Cabling terminates in communication rooms and racks. Their location, size, power, cooling and access control are part of the cabling design, not a separate topic. See our IT & Network Infrastructure direction for how we approach server and communication rooms.
Agree a labeling scheme before the first cable
Every cable, port and outlet should have an identifier that is consistent across the building and recorded in documentation. Retrofitting labels after installation is possible, but rarely as complete.
Test and document
Cable lines should be tested after installation and the results recorded. Together with diagrams and labeling records, test results form the handover documentation — the reference for every future change and fault.
Coordinate with other trades
Cabling interacts with electrical work, ceilings, partitions, security and AV. Agreeing the sequence avoids rework — and is exactly where a single coordination point helps.
