What if a 131m retaining wall didn’t take weeks to build?
For Bitzer’s new Sydney facility, our bespoke precast retaining wall system allowed a 131m long, 4m high wall to be built in around 5 days.
When retaining works sit on the critical path, every day saved matters.
The result, for this 20,327m2 site :
- Faster construction
- Reduced programme risk
- Premium finished appearance
Working alongside Prime Projects as builder, Bitzer as developer, and Lo Studio as architect, our team engineered a facility built to meet demanding industrial requirements.
The project scope included:
- 10,190m² total building area
- Structural steel rate of 13.4 kg/m²
- Full roof solar panel allowance
- 15m deep cantilever awning
- Heavy-duty concrete hardstand designed for 7-tonne SWL forklifts with 6-tonne loaded front axle requirements
- Container pavement
- On-grade loading docks
- Precast panel boundary retaining walls up to 4m high
Engineering is not about adding complexity. It’s about removing time from the programme.
