— DATA CENTRE AND STRUCTURED CABLING · TSG LABS · ONTARIO, CANADA
Start a conversationWhat this covers ↓Why physical layer problems are expensive late
Cabling pulled without an architecture. TR rooms that were not planned for what connects to them. Data centre layouts that make future changes painful. These problems surface when construction is done and remediation means tearing into finished walls. The cost of finding a design conflict at the pre-construction stage is a revision. The cost at the construction stage is a change order. The cost after acceptance is a retrofit.
Hans Study, CISSP, has designed and reviewed physical layer infrastructure for government facilities, airports, transit facilities, law enforcement buildings, and enterprise campuses across Canada. The advisory is independent. TSG Labs produces specifications that are detailed enough for competitive tendering and specific enough to hold the contractor to a standard on delivery. Owner's representative services maintain that standard through construction.
Physical layer work is easy to cut corners on and difficult for a non-technical owner to verify in the field. An independent technical eye on what the contractor is actually delivering is where the investment in oversight pays off most clearly.
When to reach out
Early design stage is ideal, before the architect draws the TR room and before conduit is specified. If that window has passed, the next most valuable point is before the RFP goes to tender. Owner's representative engagements start at the submittal review stage and continue through construction milestones and acceptance testing. Existing infrastructure assessments are standalone and can happen at any point in the facility's lifecycle.

TR Room Design
Layout, rack placement and elevation, power distribution including dedicated circuits and UPS requirements, grounding, cooling capacity, and cable management. TR rooms that were designed without considering what will actually connect to them become problems within a few years of occupancy. Most valuable at the early design stage, before the architect draws the room.
Pre-Construction and Submittal Review
Reviewing cabling contractor submittals against the specification before work begins. Substitutions that reduce performance, pathway designs simplified without engineering review, and equipment substitutions that affect system capacity are common in submittal packages. Catching them before approval prevents installed facts.
Existing Infrastructure Assessment
Documents what is actually in place, identifies cabling that does not meet current standards, and provides a realistic picture of what can be reused and what needs replacement. The foundation for accurate scope development and accurate budgeting on infrastructure projects.
How does cabling infrastructure affect physical security system performance?
IP cameras, access control door controllers, and intercoms all depend on cabling for power and data. Cabling that does not meet the category requirements for the application, or that was installed without proper bend radius or PoE power budgeting, directly affects whether those systems perform reliably. Cabling problems are a common cause of camera dropout and access control instability that gets misdiagnosed as a platform problem.
What is the difference between Cat6 and Cat6A for physical security applications?
Cat6A supports 10 Gigabit Ethernet to 100 metres and provides better noise rejection, which matters in environments with significant electrical interference. For most IP camera and access control applications, Cat6 is adequate, but Cat6A is the better long-term investment for infrastructure that will be in place for 15 to 20 years. The incremental cost difference at installation is small compared to the cost of re-cabling when bandwidth requirements increase.
Does TSG Labs provide owner's representative services for cabling projects?
Yes. Owner's representative services cover submittal review, site observations at key installation milestones, documentation review, and acceptance testing oversight. Most useful for organizations that do not have technical staff capable of evaluating the contractor's work in the field, and for projects where the cabling infrastructure will support critical systems.
