Document Description
The project is the recovery of a microtunneling boring machine (MTBM) from under the east bank of the Guadalupe River. The recovery operation involves the temporary installation of a "recovery pit" around the tunneling machine so that it can be retrieved at its current location, The project will require temporarily diverting the Guadalupe River around its current location of the MTBM and installing the recovery pit. Construction required for the recovery of the machine includes temporary placement of a cofferdam in the river, clearing of a material and equipment staging area, creating a pad for machinery to operate from, the temporary placement of sheet piles around the perimeter of the pit and the excavation of approximately 200 cubic yards of soil from within the pit area to allow hoisting of the MTBM from its current location. Upon recovery of the machine, the pit will be backfilled, the sheet piles, work pad and cofferdam removed, and the riverbed and staging area restored to their original condition. Approximately 1,740 sq. ft. of riparian woodland will be planted to restore the area affected by the project.
