Once the Robbins EPB had bored its 4.6 km (2.9 mi) drive to shaft 3A of Lot 1, it was dismantled, removed, reassembled at Lot 5, and began boring its original 8.6 km (5.3 mi) long bore in early 2014. The remaining two Robbins EPBs started excavation in 2012, working on 9.2 km (5.7 mi) and 10.2 km (6.3 mi) drives at Lots 3 and 4, respectively.
