570 tonnes. One custom-built lifting solution. More than a year of engineering.

As the Terra Verde Joint Venture team prepared for tunnelling on Suburban Rail Loop (SRL) East, the shields of its first two tunnel boring machines (TBMs) took to their places thanks to a unique heavy-lift solution engineered specifically for the Burwood site.

Using a custom strand jack heavy lift gantry, the 570-tonne TBM shields were carefully lifted and lowered into position, while other critical site infrastructure was being constructed around them. The approach meant the acoustic shed and conveyor system could be built concurrently with TBM assembly, helping maximise site efficiency and keep preparations for tunnelling moving.

Behind these lifts was more than a year of detailed engineering, planning and collaboration, bringing together the expertise needed to safely deliver one of the most critical stages of SRL East.

Webuild, as part of the Terra Verde Joint Venture, is delivering almost 10 kilometres of parallel tunnels between the future Box Hill and Glen Waverley stations, along with 39 cross passages, two station boxes, two TBM launch sites, and an intervention and ventilation shaft for the Suburban Rail Loop East Project.
