Phased electrical upgrades for multi-tenant buildings in Calgary

CCT 01What the first visit needs to establish

Collect the current distribution records, known demand information, tenant equipment requests and upcoming lease events. Distinguish confirmed loads from speculative leasing requirements. Explain the business trigger: repeated constraints, obsolete equipment, planned electrification or a specific new tenant.

Have the design team assess the whole arrangement before the owner approves isolated panel upgrades. A suite-level improvement may not resolve a limitation in the shared service, transformer or distribution. Use the commercial service upgrade guide to frame the larger investigation.

CCT 02What to include in the work order

Request a phase plan showing what each stage delivers, what it relies on and what remains temporary. Include tenant communications, shutdown coordination, access, metering responsibilities and record updates. Ask how the design protects practical future expansion without paying now for uncommitted loads.

Base-building and tenant boundaries need agreement among the owner, designers and contractors. Where utility involvement is required, use the utility's documented process and feasibility review rather than assuming the existing connection can be increased on demand.¹

CCT 03What changes the price and schedule

Staging can reduce a single major interruption but increase mobilizations, temporary works and testing. Compare alternatives on total delivered scope and tenant impact, not just the first phase's construction price. State whether temporary measures are included in the later removal and close-out.

Long-lead equipment decisions should be tied to a reviewed design. Ask the team to identify the last responsible approval date for each critical item and what happens if a tenant requirement changes. A procurement schedule and a tenant access schedule need to agree with each other.

CCT 04Information to send with your request

• Current single-line drawings and available studies, with known inaccuracies flagged.
• Confirmed tenant requirements and future leasing scenarios shown separately.
• Lease milestones, restricted periods and tenant interruption limits.
• Equipment condition reports and the reason the project is needed.
• Owner’s budget staging preferences and decision-making authority.
• Utility correspondence, landlord approvals and design-team contacts.

CCT 05What a completed job should leave you with

Close each phase against an agreed acceptance list: inspections, tests, tenant restoration, records and remaining dependencies. Update the distribution drawing after every stage. Leaving all documentation until the final phase makes intermediate maintenance unnecessarily difficult.

Keep the next phase's assumptions visible. If the owner pauses the program, the completed work should have a clear operating status and service responsibility. Handing over temporary arrangements without a documented plan simply transfers unfinished design decisions to the building operator.
