Site Audits

7.1 Site audits were carried out by ET on weekly basis to monitor the timely implementation of proper environmental management practices and mitigation measures in the Contract site. The summaries of site audits are attached in Appendix M.

7.2 Site audits were conducted on 3^rd, 10^th, 17^th, 23^rd and 31^st March 2015 by ET after the commencement of construction works for the Contract. A joint site audit with the representative with IEC, SOR, the Contractor and the ET was carried out on 23^rd March 2015. The details of observations during site audit can refer to Table 7.1.

7.3 According to EP condition 4.7 and EM&A Manual, periodic monitoring (every three months) of construction works shall be conducted to ensure the avoidance of any impacts on Sha Lo Wan (West) Archaeological Site. Access to Sha Lo Wan (West) Archaeological site for works areas and storage of construction equipment is not allowed. The 9^th inspection to the Sha Lo Wan (West) Archaeological Site was conducted on 17^th March 2015 and next inspection will be conducted in June 2015.
