This section of the specification describes and specifies requirements for the supply, delivery, installation, testing, and commissioning of diesel generator set and handing over in approved working order and providing service and maintenance during the Defects Liability Period as specified thereafter for the period stated in the Condition of
Contracts. The generator set shall comprise a diesel engine directly coupled to a three phase alternator with auxiliary equipment as further described hereinafter and shall capable of delivering and maintaining a continuous power of not less than the kVA specified in this Tender at 0.8 lagging power factor, 415 volts, three phase, 4 wire, 50 Hz supply under the operating conditions specified below and within a guaranteed range of frequency and voltage fluctuations after making full allowance for all internal losses and power consumed by ancillaries. The operating conditions shall be:
(a) Total barometric pressure : 750 mm Hg.
(b) Air temperature : 40 deg. C
(c) Relative humidity : 95%.
The generator set offered must be approved by Jabatan Kerja Raya, Semenanjung Malaysia and must be supplied by the supplier registered with Jabatan Kerja Raya, Semenanjung Malaysia. Unless otherwise directed by the S.O.’s Representative, the installation, testing and commissioning shall strictly in accordance with the requirements
of this specification and the recommendations of the generator set manufacturer. Both the engine and the alternator must be provided with name plates bearing serial numbers, ratings and other relevant data. In addition, name plate bearing the registered supplier’s name and address and date of commissioning shall also be provided. Tenderer shall submit together with his Tender original catalogues and literatures describing the generator set, engine, alternator, battery and its charger offered in addition to filling in Appendix A-1 (Schedule of Technical Data and Guarantee for Generator Set) and Appendix A-2 (Schedule of Technical Data and Guarantee for Electrical Equipment) to this specification. The price tendered in the Bill of Quantities is deemed inclusive of, whether or not these items are priced separately in the Bill of Quantities, all necessary equipment, ancillaries and auxiliaries including starting system, exhaust system, air intake system, fuel storage and supply system, and monitoring, protection and control system for the complete installation of the generator set to approved working order as shown in Drawings.

The Tenderer shall allow in his Tender for submissions of applications (together with design calculation if so required by Authorities having jurisdiction over the Works), inspections, tests and approvals including endorsement and/or certification of documents by professional/competent person and thereafter the registration of the whole Works in
compliance to the requirements of Suruhanjaya Tenaga Malaysia (STM), Jabatan Alam Sekitar (JAS) and any other relevant Authorities having jurisdiction over the Works. All cost and fee incurred in the application and process of getting the Works inspected, tested, approved and registered by STM, JAS and any other relevant Authorities, whether or not provided in the Bill of Quantities, are deemed to be included in the Contract Sum. No additional costs will be entertained in this respect. The material, equipment and installation shall conform to the principles of the latest edition standards and codes of practice laid down by the Malaysian Standards (MS), International Electrotechnical Commission (IEC), International Organisation for Standardization (ISO) and/or British Standard Institution (BSI). The “Latest Edition” shall be the edition in force at the time of contract award. The standards and/or relevant parts of the standards and codes of practice include but not limiting to the following:
