ENVISIA® has been used to create the world’s longest single pump of macro synthetic fibre reinforced concrete in Western Australia.
The growing scale and volume of modern infrastructure requires innovation in design, construction processes and concrete technology. The Forrestfield-Airport Link tunnel required each of these aspects in combination to deliver a vital piece of Perth’s infrastructure. The design of the tunnel track slab evolved from a conventionally reinforced design to a macro synthetic fibre reinforced concrete track slab, enabling significant construction efficiencies and program savings. Further efficiencies can be observed in the method of placement, which eliminates a significant amount of in-tunnel truck movements by pumping the track slab concrete from the top of each station box along the tunnel alignment. This meant that in some sections of the tunnel, concrete was being pumped almost 2 kilometres
Pumping of this magnitude requires significant collaboration between the contractor, pump operator and concrete supplier, to ensure high-quality concrete, consistent supply, best practice pumping practices and accurate planning of the construction schedule. Watch the video below to hear more about how ENVISIA® and Boral enabled this specific project.
Congratulations to the entire team on this amazing achievement.
