Construction

Managing construction noise and vibration

It is important that noise management strategies are implemented to not only reduce impact to the community, but also to our workers who are often working at the source of the noise or vibration where it is most impactful. Some construction activities are inherently noisy and generate vibration which cannot be avoided.

A Construction Noise and Vibration Management Plan has been prepared to understand potential noise and vibration impacts during construction. It identifies measures to implement to reduce and manage potential noise and vibration impacts.

Noise and vibration monitoring is occurring on site in line with the project’s Condition of Consent.

Respite is the period within the working day where noisy activities such as rock breaking, and rock hammering, will not be carried out to provide a break from the noise impacts. Noisy activities will occur between:

• Monday to Friday 9am to 12pm and 1pm and 5 pm
• Saturday 9am to 12pm

Marine piling

The new Sydney Fish market is being constructed over water and requires over 400 piles to support the new building structure, wharfs and adjacent promenade. Marine piling is expected to continue until late 2022. The marine piling process is illustrated in the following diagrams (click to enlarge):

Cofferdam construction

The cofferdam is a series of interlinked steel sheets installed around the perimeter of the new building creating a swimming pool-type structure. Once completed, the cofferdam will be around 20,000 square meters in area. Once all the marine piles for the building have been installed, the cofferdam will be de-watered to around 4.5-5 metres under the mean tide level.

The cofferdam will be a sheet and tube system installed using Giken Japanese technology. The Giken is often referred to as the ‘silent piler’ because it is typically quieter than most of the typical construction activities occurring on site.

Sheets will be installed commencing from land, working out towards the water using a press-in method. Silent pilers utilise their own weight and reaction against already installed piles to push sheets into the ground to required depths.

Typically, piles are installed using vibratory hammers which are considerably louder than a press-in method due to the vibration of steel on steel as opposed to steel sliding against each other.

Bridge Road upgrade

Bridge Road will be raised by around one metre between its intersections with Wattle Street and Wentworth Park Road. This has a number of benefits:

• The ground floor of the development and surrounding public domain would be similar to the level of Wentworth Park providing visual integration with the park.
• Assist in managing storm water around the site.
• Provide for localised widening of Bridge Road to provide an improved and widened footpath area, a drop-off area, shared cycle path, landscaping, a central median and compliant lane dimensions.
• The widened frontage to Bridge Road provides enhanced visual connection to Wentworth Park, bus drop-off, cycleway and pedestrian movement, activated street frontage with views of the workings of the fish market and landscaping.

Power upgrade works

Multiplex is currently undertaking works to upgrade the power supply for the new Sydney Fish Market. This work involves trenching and installing conduit and cabling along a 1.8km route from Lyons Road in Camperdown to the site in Bridge Road, Glebe.

Works include saw cutting the top layer of pavement, followed by trenching, duct installation and temporary pavement restoration. To minimise the impact on community, the noisier work will be undertaken prior to 12am to provide respite to residents. Work will be limited to 2 nights per week in each zone.

These works are expected to continue into early 2023. For more information, refer to the power upgrade fact sheet below.

We provide fortnightly email updates regarding the location of work sites, scheduling and progress of the work. To receive works updates register for construction updates.
