Comparing electrical bids in Calgary | Calgary Commercial Electrician

CCT 01Create a common basis

Record the drawing revision, specification, addenda and scope brief used by each bidder. A quotation based on a different equipment schedule is not directly comparable. Obtain clarification in writing and share material scope changes consistently.

CCT 02Separate included work from allowances

An allowance is an assumption to be reconciled, not a fixed deliverable. Identify quantities, unit rates, equipment standards and exclusions. Distinguish the base price, alternates, taxes and owner-carried costs.

CCT 03Check the interfaces

Look for engineering, utility work, metering, demolition, civil restoration, firestopping, controls, verification and commissioning. Assign the contractor and acceptance evidence for each. A missing interface can become a change order even when both original bids appear complete.

CCT 04Compare the operating assumptions

Review access, shutdown windows, overtime, temporary power and tenant coordination. Ask whether the proposed sequence meets the building’s operational needs. A lower bid requiring unrestricted access may be unsuitable for an occupied facility.

CCT 05Read payment and change terms

Understand invoice requirements, change authorization, holdback, dispute procedures and warranty. Alberta’s prompt-payment framework may apply; obtain project-specific legal advice rather than editing statutory deadlines into a contract from a generic checklist.

CCT 06Document the award decision

Resolve material questions before issuing the order. Retain the accepted scope and exclusions with the contract. Use the same list during construction and closeout so the team can check what was actually purchased.

Questions people ask

What should I provide to obtain a useful quotation?

Describe the building, existing system, intended outcome, drawings status and operating constraints. For comparing electrical bids, include the equipment and documents identified in this guide. Ask the bidder to state assumptions and exclusions.

Does this website carry out electrical work?

No. Calgary Commercial Electrician is a planning reference. It does not employ an installation crew, hold itself out as an electrical contractor or certify contractors. Any installation agreement is with the contractor you choose.

Can a calculator replace a design or load calculation?

No. The tools show planning arithmetic and assumptions. They do not establish code compliance, available capacity, conductor sizes or protective-device settings. Have the proposed work assessed by qualified professionals.

Can the work happen while the building stays occupied?

That depends on the system, scope and safe work plan. Explain which operations must continue and which interruptions can be arranged. Have the contractor and responsible designer identify shutdown and temporary-service requirements before agreeing a schedule.
