Project Overview
Client: Multiplex
Access Equipment: 39-metre bridge with support tower and stretcher stair
Project: New Sydney Fish Market, funded by NSW Government
Location: Pyrmont, NSW
THE CHALLENGE
As part of this project, Multiplex required a safe and efficient way to transport staff from their site shed to the main construction zone. The route needed to traverse over a pedestrian walkway, span a body of water, and navigate around a large tree – all while meeting high standards for safety, stability, and long-term performance.
The access system also needed to be versatile, with the ability to adapt to changing site conditions over the life of the project.
THE SOLUTION
To meet these needs, SuperAccess™ engineered a custom 39-metre bridge supported by a tower structure and stretcher stair. The system was designed to minimise on-site disruption and accommodate existing site constraints.
In April 2022, we began by pre-installing custom concrete blocks that would support the tower. This early installation allowed the ground to settle gradually, avoiding movement issues that could arise if both the blocks and bridge were installed on the same day.
The full installation of the modular structure took place over two days in June 2022:
- Day 1: We installed the support tower, stretcher stair, and the first half of the bridge.
- Day 2: We installed the bridge section leading to the site offices, which crossed a live pedestrian footpath.
This split approach was carefully planned to minimise disruption to public walkways by limiting pedestrian detours to short, controlled windows of time.
ONGOING SUPPORT AND MODIFICATION
SuperAccess™ has continued to monitor and maintain the bridge since installation, conducting regular inspections and performance checks.
In March 2025, as the project was near completion, Multiplex requested a reconfiguration of the access system. With works progressing into the original stair zone, a modification was required – but it needed to be completed without impacting the construction schedule.
To meet this need:
- We dismantled one half of the bridge and its original stair connection.
- We then installed a new set of stairs to connect to an updated walkway.
- Finally, we removed the stretcher stairs, once uninterrupted access was guaranteed.
This approach allowed the site team to maintain continuous access, even in the face of unpredictable weather, by ensuring all changes were staged and completed within a single working day.
THE RESULT
The SuperAccess™ bridge will remain on site until June 2025, continuing to provide safe, efficient access during the final stages of construction.
Multiplex has appreciated our ability to remain proactive, responsive, and flexible throughout the life of the project – adapting as their needs evolved and delivering a practical, high-performance solution.
This project showcases how SuperAccess™ delivers tailored, long-term access solutions that can evolve with even the most complex job sites.
