Industrial & manufacturing in Calgary

CCT 01What makes this building different

Industrial facilities buy electrical work to enable or protect a process. A machine addition can affect distribution, motor starting, controls, ventilation and operating procedures. Record the process requirements and production consequences before deciding whether the project is a feeder extension, a distribution change or a larger service project.

CCT 02Electrical scopes to consider

• Industrial electrical: Motor feeders, motor control centres, drives, controls, cable tray and hazardous locations in plants, shops and warehouses.
• Three-phase power: New three-phase services and single-to-three-phase conversions for equipment, kitchens, shops and EV charging.
• Arc flash studies: Arc flash and short-circuit studies, protective device coordination and equipment labels: what an owner commissions and why.
• Preventive electrical maintenance: Electrical preventive maintenance programs: breaker testing, torque, cleaning, planned shutdowns and the annual facility permit.

CCT 03Coordinate the interfaces

Machine suppliers, controls integrators, engineers and the maintenance team should agree on the scope boundary. Hazardous areas, washdown environments, heat, dust and chemicals require appropriate assessment. Do not assume that equipment suitable in an office environment is suitable on the production floor.

CCT 04Work around the operation

A shutdown plan should be developed with operations and the qualified electrical team. Include process restart and vendor attendance, not just the electrical isolation window. Retain a clear record of temporary arrangements and the conditions for returning the line to normal operation.

CCT 05Prepare these documents

• Process and motor equipment schedules
• Existing single-line and controls documentation
• Environmental and hazardous-area assessments where applicable
• Production windows and commissioning acceptance criteria

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 Three-phase power 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.
