Case Study: Multiplex achieves major cost and schedule savings with InfraBuild steel value engineering

Multiplex saves time and costs on 300 George St with InfraBuild's structural steel value-engineering

The customer, Multiplex, faced capacity constraints in Brisbane's concrete construction supply chain for their 300 George Street high-rise project, forcing them to reconsider the building's structural frame. They engaged InfraBuild, who supplied locally manufactured structural steel, including HRS sections, welded sections, and structural linepipe, to support a value-engineering process.

InfraBuild supplied certified steel and worked with the engineering consultant to implement a value-engineered steel solution. This included pre-cambering beams to reduce weight and concrete slab thickness, which led to significant cost and time savings for Multiplex. The project used 2,500 tonnes of structural steel and realized substantial savings through a re-designed lift core, more efficient steel connections, and reduced welding labor costs.
