Common use of Testing and Commissioning Clause in Contracts

Testing and Commissioning. 12.4.1 Testing of all materials, equipment and instrumentation shall be done as specified in the Technical Specifications. Installation of all electro-mechanical equipment shall be carried out strictly as per recommendations of the manufacturers. Pre-commissioning and trial run shall be undertaken as specified in Technical Specifications covered under section Schedule 24 of this document. 12.4.2 When supplying for the first time water to the DMA, the Operator has to check that none of the replaced pipelines is still supplied with water via another pipeline inside or outside the DMA. In case of water flowing from the replaced pipeline, the Operator has to take all necessary measures to stop the supply of water to the replaced pipeline. The measures at least include a. Valves in the immediate vicinity of the decommissioned pipe shall be closed to assess the location of the connection. b. Start digging out the decommissioned pipe from both ends until the unknown connection is found. The found pipe has to be followed until at least the border of the DMA, in order to isolate the DMA properly. c. Gather latest information from SJPNL on valve settings and pump operations. If it becomes evident that the water comes through a connection from outside the DMA, it will be necessary to examine jointly with the PBC Engineer what changes in pump or valve settings has been done recently. 12.4.3 Testing for commissioning of a completed DMA shall consist of flow measurements at DMA inlet and at all service connections to determine whether the target level of water loss, as specified in Schedule 5 has been met. a. Simultaneous flow measurements shall be undertaken during a 24-hour period; b. In case the actual water loss thus measured is more than the target level, the Operator shall propose a work method, to be reviewed by the Technical Auditor and approved by PBC Engineer, to determine the cause(s) of water loss; c. The Operator shall investigate the cause(s) of water loss accordingly and shall make the necessary rectifications; d. The testing for commissioning shall then be repeated till the requirements are met and 24x7 water supply achieved in the DMA.
