Commercial new construction in Calgary

CCT 01Start with the right decision

A new commercial building needs coordinated utility supply, metering, distribution, tenant provisions and life-safety systems. The eventual tenant mix can change the load and distribution strategy. Define the base-building standard and future leasing assumptions before treating the electrical budget as fixed.

CCT 02What to put in the scope

Use this as a discussion checklist. The contract should assign each item to a named party and identify anything excluded. Ask for unclear existing conditions to be investigated before they become assumptions in a fixed price.

CCT 03Who needs to coordinate

Civil servicing, transformer location, electrical-room access, structural openings and mechanical loads all affect the electrical design. General contractor scheduling must make room for equipment procurement, authority review and utility work. Tenant permits and future fit-outs remain identifiable scopes.

CCT 04A practical project sequence

Confirm site servicing and utility feasibility, develop coordinated drawings, then procure approved equipment. Coordinate underground inspections before backfill and rough-in inspections before concealment as applicable. Plan energization and integrated commissioning as milestones distinct from equipment delivery.

Read the Commercial electrical permits in Calgary and ENMAX commercial service connections guides when planning approvals and service changes.

CCT 05What changes the price

Late tenant requirements, changed mechanical equipment, civil conflicts and incomplete utility information can force redesign. Require a schedule that identifies decisions needed from the owner and dependencies outside the electrical contractor’s control.

Continue with Electrical cost per square foot and the Comparing electrical bids checklist. Compare like-for-like scope before comparing totals.

CCT 06Calgary requirements and safety

• Calgary requires plans and drawings for new construction or service upgrades of 600 A and higher, including all high-voltage installations. ¹
• Calgary requires separate electrical permits for commercial base building work and for tenant spaces. ¹
• A new or upgraded site must be approved by the electrical inspection authority, following the ENMAX metering standard, before ENMAX energizes it; energization is requested through the retailer. ²

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.

CCT 07What the owner should receive

The owner should receive a complete and usable building record: drawings, inspection documents, equipment schedules, warranties, settings, training and maintenance requirements. Track tenant-ready provisions so leasing information matches the actual installation.

Keep proposed work, accepted changes, inspection evidence and remaining deficiencies together. A verbal assurance is difficult for the next property manager or maintenance contractor to use.

CCT 08Apply the scope to your building

Warehouses & logistics · Office buildings · Condos & multi-family

Select the industry guide for its equipment, access and operating considerations. The electrical scope should reflect the actual business and building, not simply its floor area.
