THE CHALLENGE
Foundations: Due to the extreme poor soil conditions and proximity the MTA sub-way line drilled in place micro-piles were chosen for the foundation supports. Building superstructure columns and CMU walls were supported on cast-in-place concrete pile caps and grade beams. The soil conditions at the site were so poor the main floor slab could not be supported directly. As a result the main floor of the building was designed as a pile support cast-in-place concrete two-way slab.
THE SOLUTION
Super-Structure: Need to discuss the floor vibration issues with the second floor gym and how it was overcome.
