6.3
Acoustics and noise pollution control
Building renovation and retrofitting works within a shopping mall always generate different kinds of nuisances such as
noise, waste and dust, in which noise directly affects potential retailers and transient shoppers.
What contractors and mall developers can do to alleviate the nuisance during different stages of construction are listed in
the following section.
6.3.1 Recommendations for site practices
During demolition and construction
• Restrict noisy work and use of equipment that generates noise, (e.g. hand-held breakers) to less sensitive
hours of the day
• Avoid noisy activities before 9 am and after 7 pm
• Use noise barriers or absorbers and fit noise mufflers to machines
• Place rubber mats/pads beneath work benches and noisy machines
