New Documents Introduced This November

Updated to incorporate the changes first implemented in CCDC 2 – 2020, these three contracts have been modernized to provide a clear and consistent framework for construction processes and minimize the risk of disputes and misunderstandings.

  • CCDC 2MA – 2023 “Master Agreement between Owner and Contractor” and CCDC 2MA – 2023 “Work Authorization”
  • CCDC 4 – 2023 “Unit Price Contract”
  • CCDC 18 – 2023 “Civil Works Contract”

The most significant update is the introduction of the Ready-for-Takeover project milestone, which triggers the handover of warranty, care, custody, and control.

Some other significant changes include provisions addressing early occupancy by the owner, the relocation of some clauses to the Division 01, new language addressing payment legislations like the Ontario Construction Act, new insurance requirements, new provisions on indemnification and waiver of claims, and revisions to health and safety clauses to address all parties’ roles and responsibilities.

These updated contracts mark an important step as CCDC continues to update their library of contracts and guides to reflect the new standards set out in the CCDC 2 – 2020
