SYDNEY YARD ACCESS BRIDGE CENTRAL STATION

SYDNEY YARD ACCESS BRIDGE CENTRAL STATION

A M2480D heavy lift crane solution to support enabling works for Sydney Metro construction.

PROJECT OVERVIEW

Construction of the Sydney Yard Access Bridge (SYAB) Project at Central Station was the first early and enabling works package for the Sydney Metro City & Southwest project. With plans to construct the bridge by lifting structural steel bridge sections and precast elements into place during restricted rail possessions over an existing network, construction partners, Laing O’Rourke, turned to The Men from Marr’s for a heavy lifting solution that could reduce complexity and de-risk the project.

THE CHALLENGE

Working within a severely restricted space, over a live rail line and during time-restrictive off-peak rail possessions was deemed too risky for a crawler crane set up, so the client turned to us for a simpler solution.

OUR SOLUTION

Using one of our M2480D – with its heavy lift capacity and extra reach – the structural steel bridge sections were preassembled alongside the operating rail line and lifted into place in a single lift during the scheduled rail possession.

THE RESULT

With the assembly of the sections taken off critical path and the M2480D installed onsite and ready to lift as soon as the rail possession took place, Marr’s solution reduced complexity and supported the project from a safety, time and cost point-of-view – supporting Laing O’Rourke to deliver the project on time.

LET'S TALK ABOUT HOW WE COULD ADD VALUE TO YOUR PROJECT

We work with our clients to find a craneage solution that works – no matter how big or complex the job is. If the right crane doesn’t already exist, we’ll build one to suit the needs of your project.

Construction of the Sydney Yard Access Bridge (SYAB) at Central Station involved working within a restricted space, over live rail lines and during time-restrictive rail possessions at Australia’s busiest railway station.

The heavy lifting capacity and reach of Marr’s M2480D Heavy Lift Luffer (HLL) allowed construction partners, Laing O’Rourke, to install the crane at sufficient distance for the M2480D to remain in place during scheduled rail possessions for the installation of the bridge sections.

The original craneage scheme planned for large crawler cranes to lift the bridge in two smaller sections and assemble in-situ due to limitations on load and reach capability. However, coordinating the crawler crane set up and rig time within the scheduled rail possession was deemed too risky.

Using one of our M2480D Heavy Lift Luffers (HLL) – with its heavy lift capacity and extra reach – the bridge sections (weighing up to 60t) were preassembled alongside the operating rail line and lifted into place in a single lift during the scheduled rail possession. With the assembly of the sections taken off critical path and the M2480D installed onsite and ready to lift as soon as the rail possession took place, the crane was able to remain in place during installation and used in out of possession times to complete pre-assembly works.

Marr’s solution reduced complexity and supported the project from a safety, time and cost point-of-view – supporting Laing O’Rourke to deliver the project on time. It was also the first time a tower crane of this size had been used to do the heavy lifting on a major rail infrastructure project – paving the way for a new approach to the construction of similar projects across Sydney and around the world.

“The use of the tower cranes at SYAB pushed a lot of boundaries … An idea that raised more than a few eyebrows turned out to be the best engineered solution for our client,” said Huw Griffiths, Project Lead, Laing O’Rourke.
