Trades Definitions Version 9.0 is Out

 

Note to Readers and Users of this Document

The 2024 Edition, Version 9.0 of the Alberta Trade Definitions has completed major revisions to select trade definitions, most notably to:

▪ Metal Sheet Roofing

▪ Roofing and Related Sheet Metal

▪ Entrances, Storefronts and Windows

▪ Curtain Wall and Glazed Assemblies

▪ Glass and Glazing

▪ Painting

We have also made numerous minor revisions throughout the document that may or may not affect the work of each trade but eliminates the ambiguity of the existing verbiage that could result in unforeseen work due to misinterpretation of the language used.

For a quick review of the changes made please refer to Version 9.1 which shows the additions and deletions in each Trade Definition.

All revisions in the 2024 edition of the Alberta Trade Definitions are clearly marked and visible to the end user of this document by way of highlighting the revisions in either “GREEN” for added items, or “RED CROSSED” for deleted items. This is done to provide both clarity and prominence to the revisions for the reader of this document.

PLEASE NOTE: It is the responsibility of each General Contractor, Trade Contractor, Manufacturer and Supplier, to review each of the respective trade definition scopes, as revisions have been made throughout the document that may or may not be different from previous versions

 
 
 

What are the Trade Definitions?

Updated for 2024, 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.

Construction associations across Alberta endorse the adoption of the ACA Trade Definitions as a best practice. Tender authorities, design consultants, specification writers, contractors, and suppliers all benefit from using and citing the Trade Definitions. Together, we can reduce confusion, errors, RFIs, and disputes – and set a standard for more consistent and compliant bids in Alberta. 

The 2024 Trade Definitions represent a comprehensive update to reflect current technology and business practice, and are the consensus result of input from many industry volunteers. The Definitions are not a tendering system – rather, they are a guideline. The allocation of work amongst trades on any given project remains the responsibility of the tender authority and general contractor.

All member companies and trade associations may request changes to any or all trade definitions by providing their request in writing to the Alberta Construction Association or the Edmonton Construction Association, care of the Trade Definitions Committee, before December 1st of each year. The request must include the change, reason for the change and the effect on the other scopes. The Trade Definitions Committee will review and rule on all requests. Changes to the definitions will be finalized and published on March 1st each year.

 

 
 

 

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.”
