Toronto, ON – The Ontario Association of Architects (OAA) and the Ontario General Contractors Association (OGCA) have released a new version of their co-authored OAA-OGCA Take-Over Procedures document. Also known as Document 100-2025, this updated resource outlines recommended steps for the closing stages of a construction contract as the owner assumes control of the project from the contractor. It approaches the topic with the interests of all parties in mind.

Available for free on the OAA Website, Document 100 was written with contractors and members of the architecture profession in mind, but it is also intended as an educational resource for clients, lawyers, consultants, subcontractors, and other stakeholders. The OAA and OGCA encourage their members—the architectural profession and industrial, commercial, and institutional (ICI) contractors, respectively—to use these take-over procedures and have them coordinated with the contract documents right from the outset of each project.

Since its publication in the early 1970s, Document 100 has been relied on in the construction industry throughout Ontario. The new version was prompted by:

• changes to CCDC contracts, particularly the introduction of the Ready-for-Takeover concept;
  
• the need to clarify that an application for release of holdback was not subject to the prompt payment provisions of the Construction Act; and
  
• concerns that some of the existing wording had not kept pace with current industry practices.

A liaison group comprising members of the OAA’s and OGCA’s governing bodies identified the need to review both Document 100 and its complementary reference tool, OAA/OGCA Guide to Project Closeout (Guide). This liaison group decided to leverage some content and concepts from the Guide and transfer them to enhance the new 2025 version of Document 100. The old Guide itself has now been withdrawn from use.

The development of the new Document 100 also included consultation with members of the OAA Practice Resources Committee, the OGCA board, and external legal counsel.
