Smartways Alliance

South Perth, Como

Scope of Work

Dowsing was awarded the slipform barrier contract by the Smartways Alliance in October 2019.

  • 4550m of TL5 Slipform Barrier with 75mm – 200mm embedment

Highlights

95% of the project was completed within night shift hours next to live traffic. The mould modifications allowed us to be able to slipform over the top of a cold joint concrete footing with dowels placed every 500mm apart.

800m of barrier was also completed adjacent to an Atco drain with a 5mm alignment tolerance.
