1. PRELIMINARY
| 1.4 | General Introduction to the Procedures For the purpose of assessing if a Construction Noise Permit may be issued for construction work other than percussive piling during restricted hours the Authority shall act in accordance with the following general procedures which are detailed in subsequent sections. The Authority shall: (a) identify the most affected Noise Sensitive Receiver, determine the Area Sensitivity Rating for the area within which the Noise Sensitive Receiver is located and hence determine the relevant Acceptable Noise Level (in accordance with Sections 2.1 to 2.6); (b) calculate the Corrected Noise Level which will be generated by the construction work at the Noise Sensitive Receiver (in accordance with Sections 2.7 to 2.12); and (c) compare the Corrected Noise Level with the Acceptable Noise Level to determine if a Construction Noise Permit may be issued (in accordance with Section 2.13). If the Corrected Noise Level is equal to or less than the Acceptable Noise Level the Construction Noise Permit may be issued by the Authority in the prescribed form and may include such conditions as the Authority considers appropriate, such as the permissible items of Powered Mechanical Equipment which may be used on the construction site, the hours during which the Construction Noise Permit is valid, the dates of commencement and expiry of the Construction Noise Permit, any noise levels which may not be exceeded at specified locations during specified times and any special noise control measures that must be adopted. A Construction Noise Permit may be issued for an initial period of such duration as the Authority considers appropriate, and may be renewed before or after the date of expiry for such further period or periods and subject to such alterations or new conditions as the Authority considers appropriate. If the Corrected Noise Level exceeds the Acceptable Noise Level a Construction Noise Permit should not generally be issued. A Construction Noise Permit may not be issued for construction work which is to be carried out on or within a building which is either: (a) a Noise Sensitive Receiver either wholly or partially in use for its intended purpose at the time of the proposed construction work; or (a) directly adjoining a building which is a Noise Sensitive Receiver, such that the noise to be generated by the construction work would be transmitted primarily through the structural elements of the building or buildings and, in the opinion of the Authority, would be likely to cause an adverse noise impact on the Noise Sensitive Receiver. Applications for Construction Noise Permits for the carrying out of non-percussive piling shall also be assessed in accordance with the procedures detailed in this Technical Memorandum. The component items of equipment and plant used for non-percussive piling operations shall be considered to be items of Powered Mechanical Equipment. Construction Noise Permits for percussive piling may be issued only in accordance with the Technical Memorandum on Noise from Percussive Piling. |
