To tackle construction noise (including renovation noise) issue directly, there is a need to adopt the state-of-the-art quieter construction methods and equipment, and noise mitigation measures for construction projects.

Using Prefabricated Structure to Replace In-situ Construction

The use of precasting and prefabrication technology to replace the in-situ construction not only reduces air pollution but has also reduced the amount of mechanical equipment used on site and therefore the cumulative noise impact. Precast structures may include bridges, facades, staircases and semi-precast slabs.
