TECHNICAL MEMORANDUM ON NOISE FROM CONSTRUCTION WORK IN DESIGNATED AREAS
2. THE USE OF SPECIFIED POWERED MECHANICAL EQUIPMENT (SPME) FOR THE PURPOSE OF CARRYING OUT CONSTRUCTION WORK OTHER THAN PERCUSSIVE PILING AND/OR THE CARRYING OUT OF PRESCRIBED CONSTRUCTION WORK (PCW) WITHIN A DESIGNATED AREA
The use of any SPME as listed in Table A.3 in Annex A and the carrying out of any PCW as listed in Annex B within a designated area during the restricted hours shall require a valid Construction Noise Permit (CNP). The considerations and procedures governing whether a CNP may be issued for the above works are described in this Technical Memorandum.
A CNP shall not generally be granted for the use of SPME during the restricted hours within a designated area unless the Corrected Noise Level (CNL) for all the SPME proposed to be used does not exceed the appropriate Acceptable Noise Level (ANL) as determined according to A.2.1 to A.2.6 in Annex A. Such CNP application shall be assessed in accordance with the procedures detailed in Annex A. Notwithstanding the above, such a permit may be granted if the application is a special case as defined in Section 5.
The Authority may refuse to grant a CNP for the use of powered mechanical equipment if the Authority has reason to believe that the equipment is to be used in conjunction with the carrying out of any PCW not being permitted under this Technical Memorandum.
A CNP shall not generally be granted for the carrying out of PCW within a designated area during the restricted hours unless the application is a special case as defined in Section 5. In this case, the applicant shall submit a method statement for the carrying out of each type of PCW to describe how and where such work is to be carried out together with the CNP application for the Authority to assess in connection with these special cases.
