The Independent Tester shall:
5.1 Visit the Site and monitor the Works for their compliance with the Authority's Construction Requirements, Sub-hubco's Proposals and the Approved RDD24. The frequency and timing of the Independent Tester's visits are dependent on the progress of construction on Site. The Contractor shall agree a programme with the Independent Tester for the inspection of key construction processes and the completed [Phases of the] Works and shall give the Independent Tester advance notice of these Works being carried out on Site. The Independent Tester shall identify any aspect of the Works which needs to be inspected before being covered over by subsequent activity so that he may satisfy himself that these have been constructed in accordance with the Contractor's Quality Plan without the need for opening up.
5.2 Randomly check that the Works are being undertaken in accordance with the Construction Quality Plan that has been agreed by the Authority and Sub-hubco.
5.3 Review the written Mechanical and Electrical engineering services testing and commissioning procedure. Undertake selective witnessing of the Mechanical and Electrical services testing and commissioning. The Independent Tester has indicated that these sampling proportions should amount to approximately [fifty] percent [(50%)]. The Independent Tester shall review [one hundred] percent [(100%)] of all test results. If in the professional judgment of the Independent Tester, because of the results of witnessing (or because of other circumstances) a different sampling percentage is appropriate he shall provide a detailed report in respect of that and any change in the percentage sampling resulting in a change of fees will be borne by Sub-hubco, the Authority or the Contractor as they shall agree, failing such agreement, as determined by the Dispute Resolution Procedure.
5.4 Inspect rectification works which have previously prevented the Independent Tester from certifying the Project as complete. Concurrent with the issue of the Certificate of Practical Completion, agree a list of Snagging Matters with the Authority and Sub-hubco together with its programme for implementation and issue a Snagging Notice in accordance with Clause 18 of the Design Build Finance and Maintain Agreement.
5.5 Check the production of the relevant operating manuals, relevant approvals, test results, inspection records and as built drawings and monitor the timely handover of this documentation.
