20.1 Project Co shall procure that all aspects of the Project Operations are the subject of quality management systems in accordance with the provisions of this Clause 20 (Quality Assurance).
20.2 The quality management systems referred to in Clause 20.1 above shall be reflected in appropriate quality plans, the standard of which shall be consistent with BS EN ISO 9001 or 9002 (as the case may be) or any equivalent standard which is generally recognised as having replaced them (or either of them).
20.3 Without limitation to the generality of Clause 20.2, there shall be:
20.3.1 a Design Quality Plan;
20.3.2 a Construction Quality Plan; and
20.3.3 a Services Quality Plan for each Service,
provided that the Design Quality Plan and the Construction Quality Plan may be incorporated into one document.
20.4 Project Co shall procure that the Project Operations are carried out in compliance with the Quality Plans. All Quality Plans shall be submitted to the Authority's Representative in accordance with Schedule Part 8 (Review Procedure) and Project Co shall not be entitled to implement or procure the implementation of any Quality Plan unless Project Co is entitled to proceed with such implementation pursuant to Schedule Part 8 (Review Procedure).
20.5 Project Co shall implement the quality management systems referred to in Clause 20.1 and shall procure that:
20.5.1 the Contractor implements the Design Quality Plan;
20.5.2 the Contractor implements the Construction Quality Plan;
20.5.3 each Service Provider implements the relevant Services Quality Plan for each Service being provided by that Service Provider.
20.6 Where any aspect of the Project Operations is performed by more than one contractor or subcontractor, then the provisions of this Clause 20 (Quality Assurance) (in so far as relevant or appropriate to the activities to be performed by such contractor or subcontractor) shall apply in respect of each of such contractors or subcontractors, and references in this Clause 20 (Quality Assurance) to the "Contractor" or the "Service Provider" shall be construed accordingly. To avoid doubt, this Clause shall not be construed as requiring subcontractors of the Contractor or the Service Provider to have their own quality plans but only to comply with the Design Quality Plan and the Construction Quality Plan or the relevant aspects of the Services Quality Plan (as the case may be).
20.7 Project Co shall from time to time submit to the Authority's Representative in accordance with Schedule Part 8 (Review Procedure) any changes to any of the Quality Plans required for such Quality Plan to continue to comply with the requirements set out in Clause 20.2. The Authority's Representative may raise comments on any such proposed change only on the grounds set out in paragraph 3 of Schedule Part 8 (Review Procedure).
20.8 If there is no objection under Schedule Part 8 (Review Procedure) to a change to any Quality Plan proposed pursuant to Clause 20.7, the Quality Plan shall be amended to incorporate such change.
