Serving as the geotechnical consultant, we developed the subsurface exploration program for the project and performed test borings and geotechnical analysis. Challenges included soft soil conditions, environmental concerns and a tight schedule.
The Solutions Unearthed
- The site includes a thick layer of miscellaneous fill requiring pile foundations for the structure. We recommended timber piles for the comfort station and low height retaining walls as part of the design.
- We developed a ground improvement program for shallow densification of the existing fill below retaining walls to permit economic use of normal shallow foundations.
- We provided construction inspection for retaining wall subgrade preparation and NYCDOB special inspections for piles.
