What are the Trade Definitions?

The Alberta Construction Trade Definitions are a complete list of inclusions and exclusions pertaining to scopes of work for trades in Alberta. The definitions are used during the tendering process and to help coordinate job site activities. They specify which contractor is responsible for specific areas of work. Tender authorities, design consultants, specification writers, contractors, and suppliers can all cite and utilize the Trade Definitions. By using the definitions, we can minimize RFI's, reduce error, dispute, and litigation, and set a standard for more consistent and compliant bids in Alberta. 




Moving the Industry Forward

“There is no question that the Alberta Construction Trade Definitions are a significant step forward in attaining industry best practices. Suppliers and subcontractors now have greater assurance of competing on a level playing field. General contractors are assured of completed bids that cover the entire scope of the project. Owners benefit because they can compare ‘apples-to-apples’ compliant bids on clear definitions. In the end, everyone wins.”
