Reporting Change
ES12
There is no reporting change made for this monthly report.
Site Inspection by
External Parties
ES13
No
site inspection was undertaken by AFCD within the Reporting Period. EPD
inspection was undertaken on 13, 22 and 28 April 2021.
Future Key Issues
ES14
Due to wet season has approached, the Contractor was reminded that
all the works being undertaken must fulfill environmental statutory
requirements and to paid attention to water quality mitigation measures to
prevent surface runoff into nearby water bodies or public areas.
ES15
Construction noise would be the key environmental issue as Lohas Park Phase 4 & 6 were
already available for resident occupation. The noise mitigation measures such
as use of quiet plants and installation of temporary noise barrier at the
construction noise predominate area should be fully implemented in accordance
with the EM&A requirement.
