Novatec-MEVA-Pilbara assists with bridge construction at Australian mine
The Mammut systems, which are designed for large structures with high fresh concrete pressures of up to 100 kN/m², played a key role.
The sparsely populated Pilbara region in north-western Australia holds a huge reservoir of raw materials. Founded in 2020 to support the implementation of necessary infrastructure projects, the Novatec-MEVA-Pilbara (NMP) joint venture has now celebrated a successful debut.
The new NMP rental yard is located on the north-west coast of Western Australia in the small community town of Port Hedland. For the mining industry, this is a gateway for shipping natural resources across the world. Port Hedland has a population of approximately 15,000 and, over the years, has become a hub for the many industries that support mining operations throughout the Pilbara region. The iron ore extracted here is transported by rail to the coast and exported all over the world. The necessary infrastructure for mine access, including railway lines and roads, also requires the expansion of bridges. NMP provided formwork, services and know-how to build bridges over the existing rail facilities and rail access road, specifically a 64 m long bridge with central pier and a 230 m long bridge with five piers crossing an iron ore conveyor line.
Projects in the outback demand particularly robust and durable technology. Accordingly, almost 5,000 m² of Mammut and Mammut 350 panels along with other wall formwork (367 m² AluFix and 470 m² StarTec), STB 450 support frames and Triplex heavy-duty props were delivered to the sites for the construction of stable abutments, piers, wing walls, pile caps and foundation slabs for the around 10 m high bridges.
The Mammut systems, which are designed for large structures with high fresh concrete pressures of up to 100 kN/m², played a key role. Incorporating DW 20 tie rods, they allowed high concreting speeds of 1.5 m per hour for 25 x 10.5 m walls up to 2.5 m thick. The construction team had no problems assembling and dismantling the simply smart MEVA systems. The 1.3 m wide LAB platform units were also installed quickly and gave the operatives plenty of space to move and work. The 4.5 m high STB support frames ensured that the high loads could be safely supported.
MEVA’s lightweight AluFix hand-set formwork was used for the ground works and upstand walls, and the universal StarTec steel formwork for the wing walls while the Triplex heavy-duty prop solution was deployed in constructing the single-sided walls, piers and abutments.
To optimise business expansion in the region through the provision of technical equipment and services for future projects, formwork manufacturer MEVA and distributor Novatec Formwork Systems formed the Novatec-MEVA-Pilbara joint venture. For 20 years, the two companies have collaborated successfully in meeting the high safety requirements placed on many projects on the fifth continent. Novatec is involved in large-scale projects, such as high-rise buildings, commercial centres and residential parks, throughout the country. Under the joint venture, the required systems and services are delivered quickly and flexibly to the resource-rich region.
