Unless otherwise specified in the Drawings and/or Bill of Quantities, the generator room/building shall be acoustically treated to achieve a guaranteed noise level not exceeding 65 dBA measured at one metre distance away from the generator room/building. The design criteria shall consider the noise profiles of the generator set and the following major noise sources shall be isolated without affecting the performance and
output of the generator set: –
(a) Radiator fan noise;
(b) Engine radiated noise;
(c) Engine exhaust noise;
(d) Air intake fan noise, if any; and
(e) Ventilation fan noise, if any.
The design shall in accordance with BS 8233 – Sound Insulation and Noise Reduction for Buildings: Code of Practice. Notwithstanding to achieve the guaranteed noise level as specified above, the design and the complete installation of the equipment shall also meet the requirements set by Jabatan Alam Sekitar (JAS). The Electrical Contractor is responsible to submit application together with design drawings and calculation sheets including relevant data sheets to JAS for approval. No work including fabrication of the silencers, acoustic doors and any other acoustic treatment shall be carried out without such application being approved by JAS. The cost incurred including all fee required for the submission and approval of the application to JAS, whether or not provided in the Bill of Quantities, is deemed to be included in the Contract. Before commencement of any work at site, a copy of such application, together with design drawings and calculation sheets including relevant data sheets, and its approval from JAS shall be submitted to the S.O.’s Representative.
