The machine and continuous conveyor system were assembled at the jobsite with the help of Robbins field service technicians, rather than in a shop. The TBM was launched on November 18, 2013, just three months after assembly began.
"The machine performed quite well," said Gregg Rehak, tunnel supervisor for contractor Super Excavators. ³Now we have to remove the TBM, which will take about four weeks; then rebar tying and concrete pouring can start."
Once finished, the tunnel will have a storage capacity of 42Ml per day, which will provide a significant boost in water quality for Lorain. Final project completion is set for 2015.
