A 50ft tall staircase down to a dock on the Chesapeake. It had a beautiful view but unfortunately it was built with wooden posts dug shallow into the ground. The stair tower was beginning to lean out towards the water.
As a structural retrofit to the existing staircase structure a steel structure was going to be built to attach to the stair case. This steel structure was to be supported on adequate piles. Helical piles were chosen because of their ability to be installed where access is difficult. The helical piles were installed with a small hand held drive head.
All eight piles were installed to a depth of 20ft in one day. Their galvanized custom design caps will be welded to long pieces of channel steel and be part of a new steel structure that will clamp to the existing structure. Further movement is arrested.
