Appendix E.2 Manual Noise Monitoring Results for April 2003

 

 


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 early 2004. As there was no construction work in March 2003, manual noise measurements at Pak Kok Tsui residences was suspended in this reporting month.
