Data centres & server rooms in Calgary

CCT 01What makes this building different

A small server room and a proposed data centre are different projects. Both need coordinated power, cooling and operating requirements, but large facilities introduce utility and system planning questions beyond a building contractor’s scope. Do not assume a general connection announcement establishes available supply for a particular site.

CCT 02Electrical scopes to consider

• Generators & transfer switches: Standby and emergency generators, automatic transfer switches, load banks and the testing emergency power systems need.
• Switchgear & transformers: Switchgear, switchboards, panelboards and transformers: replacement, coordination with the utility, lead times and shutdown planning.
• Commercial service upgrades: Raising a building’s service: capacity checks, the ENMAX application and investment, CT metering, drawings and the shutdown.
• Arc flash studies: Arc flash and short-circuit studies, protective device coordination and equipment labels: what an owner commissions and why.

CCT 03Coordinate the interfaces

IT, electrical and mechanical designers should agree on the load basis, UPS arrangement, generator support and maintenance approach. Define where responsibility changes between the utility, landlord, facility operator and IT equipment owner. A redundant component does not by itself make an entire supply path redundant.

CCT 04Work around the operation

Plan commissioning and maintenance with the operator. Identify dependencies on cooling, controls, communications and fuel. Document supported loads and system limitations so future rack additions do not silently invalidate the original design assumptions.

CCT 05Prepare these documents

• IT load and growth assumptions
• Continuity and maintenance requirements
• Electrical and cooling concept
• Utility feasibility and commissioning plan

Label missing or uncertain information clearly. An old drawing is a useful starting point, but the proposed work should be based on verified conditions. Define who will investigate gaps and how that affects the price.

CCT 06Compare scope before price

Start with Generator & ATS cost. Then use Comparing electrical bids to separate equipment, installation, approvals, testing and exclusions.

Identify owner-carried costs and recurring service fees. Record access and interruption assumptions so a quotation does not quietly depend on working conditions the building cannot provide.

CCT 07Approvals and completion

Use the Commercial electrical permits in Calgary guide to plan the trade-permit scope. Base-building and tenant work have separate electrical permits in Calgary. ¹

At handover, retain inspection results, final drawings, operating instructions and a list of resolved and outstanding deficiencies. Assign responsibility for ongoing inspection and maintenance.

These pages concern Calgary. Confirm the authority and wire-service provider for Airdrie, Rocky View County or another neighbouring municipality. The applicable permits and connection process may differ.
