A preliminary acoustic assessment has been undertaken for the Station Street/Bondi Road, Bonbeach level crossing removal. Noise emissions will be assessed in accordance with the Passenger Rail Infrastructure Noise Policy and Environment Protection Authority Noise Control Guidelines Publication 1254 for rail operations and construction noise respectively. The design alignment for the project will be acoustically modelled to assess the potential noise emissions from the new rail system, including noise from the passenger and freight rail services. Noise modelling will compare the future rail operation noise with the applicable noise policy criteria to determine if noise mitigation measures need to be considered. Construction noise from typical plant and equipment used for rail construction should be acceptable for daytime use. Evening and night construction works are likely to exceed the applicable noise criteria and, would need to be managed as part of the Environmental Management Framework or equivalent document to ensure noise impacts are avoided, minimised or managed.
