BOSFA were approached to offer a design solution for the shotcrete covering the contiguous piles surrounding the New Children’s Hospital in Perth Western Australia. A State Government project constructed by the John Holland Group.
The design requirement was for a design crack width of 0.2mm being achieved using Bekaert®’s proprietary design software. The solution uses a std mesh and a dose rate of Dramix fibres to achieve the desired crack width.
With approximately 5Klm of shotcrete the design has proved to be a very cost effective design solution.
Civil type shotcrete utilising a Dramix steel fibre reinforced concrete solution, can simplify the design and make construction much faster and easier.
Dramix® RC-80/35-BN (end-hooked, length 35mm, diameter 0,45mm) and a single mesh ?8-15cm were applied. Due to the curvature and the limited shell thickness of 6cm to 12cm it would have been very difficult to install a complicated traditional reinforcement in an accurate and safe way. Concrete was applied by shotcrete technology. With the chosen combination, both serviceability and ultimate limit state could be designed.
