A CCN (Contemplated Change Notice)<\/strong> is a formal contract document issued by the consultant, architect or owner asking the contractor to price a potential change to the work. The contractor returns a quote, and if the owner accepts it the CCN becomes a change order; it does not authorize the work on its own.<\/p>\n

CCN is mostly Canadian usage. The same step is called a proposed change notice (PCN), change request or request for pricing elsewhere, and a proposal request in AIA contracts (AIA G709). In general project management, CCN can also mean a change control note.<\/p>\n

How the CCN process works<\/h2>\n
    \n
  1. The consultant issues a numbered CCN describing the change, with sketches or revised drawings and a date for the response.<\/li>\n
  2. The contractor gets subcontractor and supplier quotes, prices labour, material and equipment, adds the markups allowed by the contract, and states any schedule impact.<\/li>\n
  3. The consultant reviews and negotiates the quote.<\/li>\n
  4. If the owner accepts, a change order<\/strong> is issued and signed, adjusting the contract price and time.<\/li>\n
  5. If the work can’t wait for agreement, the owner can issue a change directive<\/strong> to proceed, with the price settled later.<\/li>\n<\/ol>\n
