discharging to the public drainage and loose sand bags were observed in the
catchpit at W51. The Contractor was recommended to provide additional sand
bags/bundings with shotcreting around the sump pit and additional sand
bags/bundings to the inlet and outlet of the catchpit. Also, the Contractor
was recommended to provide geotextile coverage on site boundary to prevent
seepage of surface run-off generated from works area. Temporary exposed
slopes/surface should cover up with tarpaulin sheet to minimize the
generation of silty run-off. Deposited silt and debris inside drainage in W51
should be cleared. Muddy run-off should be diverted to desilting facility and
closely monitor the drainage system to ensure the drainage system is properly
maintained. No substandard surface run-off from construction site shall be
discharge to public drains. |
