Challenges on site
Earthworks on this tricky site have provided the project team with some significant challenges. Having to navigate deep gullies with variable ground conditions proved difficult.
Extensive shotcrete facings are applied against the existing ground, as excavations go deeper to ensure the road above doesn’t fall in on the work team below, and to provide stability to the single lane road above. This is challenging and time consuming, adding to project timelines and budget, but is necessary to ensure works are carried out safely.
We indicated in our July newsletter that we were hoping to reinstate two lanes between Sites 11 and 13 by mid-September. Unfortunately, because of the challenges mentioned, this is not going to be possible. The opening of two lanes at Site 13 will only be achieved when the retaining wall structure is in place.
