What CCDC 2 is
CCDC 2 is the Stipulated Price Contract published by the Canadian Construction Documents Committee. It is the most commonly used owner-contractor agreement in Canadian construction and the form most ExAC candidates will encounter on their first projects as Intern Architects.
The contract sits between two parties: the Owner and the Contractor. Together with the Agreement, the Definitions, and the General Conditions, it sets out a fixed price for the Work, how that price is paid, how changes are priced, how disputes are handled, and when the Owner can take the building over. The Consultant, normally the architect of record, is named in the Agreement and administers the Contract on the Owner's behalf.
The CCDC describes the document as the product of a consensus-building process aimed at balancing the interests of all parties on a construction project. That balance shows up everywhere in the General Conditions: notice periods cut both ways, holdback works for both sides, and the dispute resolution ladder applies equally to Owner and Contractor.
