New Sydney Fish Market

Overview

This iconic project encompasses design finalisation, value engineering, supply & install of all steel building piles & promenade piles within Sydney Harbour for the partly submerged 100yr design life New Sydney Fish Market.

Head Contractor

Multiplex

Principal

Infrastructure NSW

Original Works

May 2022 – June 2023

Budget

$89M (current)

01. Our Role

International procurement and logistics of all steel tubular piles is completed lengths, unloaded, and stored direct from China vessel in Glebe 2 storage facility.
Piles compression loads up to 27MN, and tension loads upwards of 6MN tested and certified through an elaborate pile installation program.
Basement piles installed concurrently with SSP cofferdam construction by others.
Cut down, recycling of pile offcuts and capping of piles once installed.
260 steel tube building piles driven into rock within the harbour ranging from 700-1350mm diameter, high capacity Junttan HHX300 hydraulic hammer.
Temporary works for tower cranes installed in marine conditions including crane erection in conjunction with specialist tower crane supplier.
146 steel tube promenade piles driven into high strength rock ranging from 610-711mm diameter, HDPE-sleeved.

02. Issues and Resolution

SMC has been instrumental in resolving numerous design and construction issues, including (as a minimum) significant loads on foundation piles (Pile compression loads achieved 27MN, and tension loads upwards of 6MN), plus rectifying the 5m cantilever on the cofferdam (installed by others). SMC cannot list all collaborations and resolutions, but more than willing to discuss the extensive increase in our scope as SMC became the “go-to” contractor to resolve issues and progress the Project.

03. Safety

SMC engaged with Multiplex in “High Risk Workshops” (HRW) for 16 critical activities including piling, dredging, seabed cleanup and precast installation.

HRWs showcase the process and steps involved for executing the proposed activity with particular attention to the engineering and safety controls that are being implemented for successful execution of the works.

HRWs are attended by representatives from the client, head contractor, and SMCs Project Manager, Project Engineers, site management and relevant site crew. It is also attended by the client QA, Safety and Plant Managers.

“Infrastructure NSW’s New Sydney Fish Market project where, in addition to having installed more than 500 piles stand-alone steel piles ranging from 600-1350mm diameter, we were also asked to take over & complete the early works pile extraction & demolition contract works from one of our competitors (who were unable to complete the task).”

Our Approaches

Living seawall made up of ~300 x sea tiles
40x hanging fish habitats from basement structure
45x benthic fish habitats deployed around the basement on the seabed
450m3 underwater rock rubble reef
Plastic and microplastic pollution:
Installation and monitoring of 8 x Seabins around the construction site. Capturing floating debris and filtering water: https://seabin.io/home
SMC recycled over 650 tonne of steel pipe that was returned to use as steel reinforcement at Infrabuild’s Western Sydney Reinforcement Plant. The remainder of steel piles were sent to Bluescope’s facility at Port Kembla for steel recycling.
An additional 24 tons of steel pile offcuts were removed from the structural basement steel piles and were reused in the DPI Fisheries Forster and Terrigal Offshore Artificial Reefs, providing additional fish habitat and ensure that the Reefs are stable during large storms (see left)
The use of full depth silt curtain to the perimeter of the project encapsulates any turbidity or slicks from within the site
Imported and placed 80,000 tonne of clean sand on existing depauperate seabed to encourage biodiversity
