44 2 Contractor's Quality Plan 2. Contractor's Quality Plan 2.1 Scope This Section sets out the minimum requirements for the quality assurance of the Contract Works quality assurance. The work required must be completed in accordance with Section 1, TNZ Q/1 (Q1) and Q/2 (Q2) and the following requirements. 2.2 Response Times Table 2.1 states the response times for preparing, submitting, reviewing, updating and accepting the CQP. Activity Draft CQP Final CQP Pre-commencement Review Surveillance Review Annual CQP Review Table 2.1: Contract Quality Plan Assessment Within 2 weeks of the Date of Acceptance of Tender Within 1 week of the Engineer s review of the draft CQP and before the date of possession of site A minimum of 72 hours following the Engineer s notification of the review A minimum of 24 hours following the Engineer s notification of the review Within 3 weeks of the anniversary of Acceptance of Tender 2.3 Contract Quality Plan The Contractor must develop the Contract Quality Plan (CQP), and the contract works must be undertaken in accordance with the CQP. The CQP must be based on the Contractor's quality, health and safety and environmental management systems. Nothing in the CQP will take precedence over the requirements of the Contract Documents. In particular, nothing in the CQP will relieve the Contractor from the performance of the Contractor's obligations under the Contract Documents even though the CQP has been approved by the Principal or the Principal's Agent. The expectation is that the Contractor will take full ownership of all quality assurance aspects so that the Principal can be assured that the acceptability of the end result will not be attributed to a quality issue CQP Implementation and Management The CQP must be implemented and managed so: a) the Contract Works are identified, programmed and completed within the response times specified b) the Contract Works are completed according to the Contract Documents PS 7
