Dewatering involves temporarily lowering the water table to allow soil to be excavated from a work site without it refilling with water. This process will be used in construction of the project's underground station boxes and portals.

On Saturday 13 May Transport Minister Rita Saffioti announced the arrival of our first tunnel boring machine.
Works are now underway across all four major construction sites to prepare for the start of tunnelling. At Forrestfield, our busiest site, excavation of the dive structure is progressing well and in the coming weeks will reach a depth of 14m.
