Structured Cabling System Design Checklist for a New Office or Relocation

Start your infrastructure planning 3 to 6 months prior to move-in day. Cabling is dependent on ceiling access, electrical work and landlord approval, and all of those have lead times. A good office relocation IT checklist will start with that timeline, as once the furniture and staff are in place, you can't rush the cabling.

Count what you need today, then plan for what you will need later.

• Assess current workstations, fixed desks, and hot-desking zones.
• Plan for 3-to-5-year company growth so you don’t run out of ports immediately.
• Include shared devices such as printers, displays, and room schedulers.

Adding ports later means opening ceilings and re-running cable. Adding spare capacity now costs far less.

Don’t copy and paste your old setup. Your current office may have grown piecemeal, and your new space may have its own legacy problems. Legacy cables at the new location may be outdated, poorly labelled, or improperly terminated.

Qualified data cabling specialists can inspect existing runs, test them, and tell you what to reuse and what to replace. Unlabeled or uncertified cable is a liability, not an asset.

Match the cable to the job:

• Cat6: cost-effective for standard gigabit desk drops.
• Cat6a: vital for future-proofing, higher bandwidth, and 10 Gig over longer distances.
• Fibre Optic Backbone: Crucial for inter-floor connections, high-speed data centres, and heavy data loads.

Lots of offices use Cat6a for the horizontal runs and fibre for the runs between the equipment rooms. That's a balance of cost now and future capacity.

Print out the physical floor plans and mark every data drop location area by area. Walk the space with your IT lead, office manager, and cabling contractor. Check where the desks, meeting rooms, printers, and reception areas will be. Note any obstructions (columns, glass walls, fire-rated partitions, etc.).

Use these allocations as a starting point:

• Standard workstation/desk: 2 drops minimum (1 active primary and 1 spare/secondary device).
• Conference/Board Rooms: 3-4 drops (display screens, conference tables, room booking schedulers, and ceiling Wi-Fi APs).
• Printer / Copier Stations: 1 dedicated hardwired drop, which avoids wireless instability for heavy print queues.
• Wireless Access Points (WAPs): 1 ceiling drop per AP, placed according to a professional wireless coverage heat map.
• Security & Access Control: Individual PoE drops for IP cameras, card readers, and door intercoms.

Power over Ethernet (PoE) lets one cable carry both data and power to cameras, access points, and readers. That reduces the electrical work needed at each device location.

For conventional Cat6 and Cat6A structured cabling, the permanent link is normally limited to 90 m, and the complete channel (including patch cords) is normally limited to 100 m. You need to bear that in mind when you're planning your equipment rooms, your cable runs and your workstation connections.

Every structured cabling system design must respect this limit when positioning closets and routing cable. Runs that exceed it fail certification or cause intermittent errors that are hard to trace.

Main Distribution Frames (MDFs) and Intermediate Distribution Frames (IDFs) should be positioned centrally. A central position will obviously minimize the horizontal run distances and will also keep the structured cabling layout as simple as possible to manage and to troubleshoot. On a larger site or a multi-floor site, you would have an IDF on each floor, linked back to the MDF via a fibre backbone.

Choose floor-standing or wall mounted racks with built in capacity for patch panels, network switches, routers, and UPS. Leave at least 30% of the rack space free for future growth. Racks that are too full make cable management a nightmare and will also lead to poor airflow.

Power interruptions and inadequate cooling can create serious risks for network equipment, affecting performance, availability, and equipment lifespan.

• Provision dedicated electrical circuits for telecom racks.
• Ensure adequate ventilation, or dedicated server room cooling, so switches and enterprise hardware do not overheat.
• Size the UPS to carry critical equipment through short outages.

Treat the telecom room as part of your overall structured cabling system design, not an afterthought handed to the electrician at the end.

Install the correct cable trays, J-hooks, and conduits through the ceilings and walls. Keep the data cables physically separated from the high voltage electrical lines to avoid EMI.

Experienced data cabling specialists follow manufacturer-specified bend radius requirements and avoid overcrowding cable pathways. Both of those things are important in terms of protecting the performance of the cable over the lifetime of the installation and in terms of leaving the pathway sufficiently flexible for future additions.

Implement a standardized naming convention based on the TIA-606 labelling standard. Label both ends of every cable, as well as patch panel ports and wall faceplates, so they match identically.

Consistent cable labelling reduces the time it takes to troubleshoot and makes future network changes, workstation moves, and infrastructure upgrades a lot easier. Without them, every fault is just a tracing exercise.

Basic continuity testers can only identify the most common types of wiring faults and are of no use in verifying the actual transmission performance of a cable. Professional cable certification testing assesses the installed link against the relevant cabling category and industry standards and is able to identify any performance issues prior to the network going live.

Reputable data cabling specialists supply the test results for each link. Keep these reports on file. They document that the cabling met the specification on day one, which helps with warranty claims and any later disputes.

Compile the final deliverables:

• As-built floor plan drawings.
• Cable ID logs.
• Port-to-location mapping.

The records must show the final structured cabling layout (including any changes that have occurred during installation). The documentation must be up to date so that troubleshooting is quick and future moves can be planned easily.

Pre-configure switches, firewalls, routers, and Wi-Fi access points off-site so they are plug-and-play ready on arrival. Coordinate this step with your structured cabling and installation schedule so that equipment and cabling are ready at the same time. Staging reduces on-site configuration work and shortens the move-day window.

Choose between a phased department move or a structured weekend cutover.

• Phased move: the departments are moving in stages. That reduces the risk but does mean we'll be running two sites for a longer period of time.
• Weekend cutover: Everyone moves at once over a weekend. This is faster, but it needs a detailed plan and a tested rollback option.

Add the chosen approach, with named owners and times, to your office relocation IT checklist. Also notify your internet provider and phone vendor early, since circuit installations often carry long lead times.

Before staff arrive, verify the following:

• DHCP address allocation and internet gateway stability.
• VoIP call quality (latency, jitter, and packet loss).
• Enterprise Wi-Fi coverage throughout all office areas.

Record the results and fix any faults before Monday morning. Treat this validation as the final item on your office relocation IT checklist, not an optional extra.
