Station Excavation

Crews are beginning to excavate the station box , which is the portion of the station located underground. Starting next week, crews will begin drilling shafts up to 120 feet deep using drill rigs. These shafts will be backfilled with concrete and reinforced with steel beams that will be placed using cranes. Once the crews have completed the installation of the shafts, they will begin digging to remove and haul away dirt. As crews dig down, wood will be installed between the steel beams in adjacent shafts. This wood is called lagging. Long nails, called tiebacks, will be drilled into the surrounding soil to support the station walls as the excavation progresses. At its deepest point, the excavation for the station will reach 95 feet below ground. The excavation will be complete in approximately one year.
