Future Key Issues
ES14
Due to
the dry and windy season has begun in Hong Kong, the Contractor was reminded
that all the works to undertaking must be fulfill environmental statutory
requirement, especially construction dust come from working sites of the
Project.
ES15
Construction noise would be the key environmental issue as Lohas Park Phase 4 was 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.
