Appendix E.2 Manual Noise Monitoring Results for August 2002

 

 

The hoarding works for the construction of transmission system at Pak Kok Tsui were completed on 11/5/2002.  The civil works would tentatively commence in November 2002.  As there was no construction work in August 2002, manual noise measurements at Pak Kok Tsui residences was suspended in this reporting month.
