McMahon & Mann and Parsons Brinckerhoff, Inc. developed design plans for a new dry dock for the Maid of the Mist vessels in the lower Niagara River just downstream of Niagara Falls. Access to the drydock is from the former Schoellkopf Power Plant elevator tower.
McMahon & Mann and Parsons Brinckerhoff, Inc. developed design plans for a new dry dock for the Maid of the Mist vessels in the lower Niagara River just downstream of Niagara Falls. Access to the drydock is from the former Schoellkopf Power Plant elevator tower. The lower portion of the tower was surrounded by more than 20 feet of shale that had fallen from the rock slope sine the plant was abandoned in the 1950s.
McMahon & Mann designed an anchored soldier pile and lagging wall to support the excavation in front of the elevator and to retain the old historic Schoellkopf Plant “B” wall.
Micropiles were used as soldier piles because they could be drilled through the rubble in front of the elevator tower. Rock anchors were used to provide wall stability A concrete facing was placed over the micropile wall with form liners to create a stone appearance.
