Excavation and earthworks projects

This project had a broad scope of works and a range of challenges that needed to be overcome, including the constraints of working in a residential area, and design changes.
The scope of this inner-city project included utilities installation and earthworks. The challenges for our team involved the presence of groundwater, a tight building footprint, and a live rail line.
