Australian-based heavy lifting tower crane specialists, Marr Contracting Pty Ltd (The Men From Marr’s) has been awarded the contract to deliver specialised heavy lifting crane services on the construction of the East Rockingham Waste-to-Energy (WtE) project in Western Australia.
The AU$511 million project is located in the Kwinana Industrial Area, 40 km south of Perth and it will be the second-largest Waste-to-Energy (WtE) in Australia. With a capacity to process 300,000 tonnes of residual waste from non-recyclable commercial and industrial sources every year, East Rockingham WtE will deliver a cost-effective waste treatment solution and a vital source of dispatchable renewable energy to the City of Perth.
After Acciona and their partner, Hitachi Zosen Inova (HZI) were awarded the lead contract for engineering, procurement and construction (EPC) on the project in 2019, Acciona contacted Marr Contracting to work with them to develop a lifting strategy and craneage methodology that supported their modular construction.
The geotechnical conditions of the greenfield site, which is located in a high wind area close to the coast, posed a number of challenges that Acciona wished to address based on experiences on similar projects completed or currently under construction. Their primary concern was to find a solution that would reduce the number of lifting activities during the construction of the project.
“Marr Contracting was contacted at the initial planning stage because they had a solution that would minimise interface and project risk with a ‘one size fits all’ crane. Working with Simon and the Marr team from concept to on-site mobilisation has been a pleasure. We look forward to a safe and successful project as we ramp up over the coming period.” said Kevin Meldrum, Construction Manager at Acciona Geotech.
Marr’s solution – using a 330-tonne capacity M2480D Heavy Lift Luffer (HLL) – will allow critical lifts, weighing up to 150 tonnes, to be completed by a single crane from a fixed location, with a total site coverage of over 32,000 square meters and an ability to place 25 tonnes anywhere within that coverage.
“Working closely with Acciona’s construction team during the early stages of the project, we’ve been able to design a simple craneage solution that will help to reduce congestion and improve safety on-site. This is a great example of a client engaging us early in the construction planning stage of the project to achieve a safer, more efficient lifting solution, that importantly drives program security for the project,” said Marr’s Managing Director, Simon Marr.
“We support the contractor’s great initiative to engage the Marr Contracting. The construction methodolgy not only improves safety but also achieves quality assurance, which is the most important factor for the owners of the project”, said Mike Cramb, CEO – East Rockingham Waste to Energy.
The M2480D HLL has been installed on-site, with Marr’s involvement in the project expected to run until Q1 2022. The East Rockingham WtE project is due for completion in December 2022.
