126 STECOR 1400 piles were spec'd for the foundations of Draper Hall at the Metropolitan Hospital in Manhattan and were installed to a depth of 75'.

ZERO SPOILS REMOVED AND A FASTER INSTALL TIME IN A LIMITED ACCESS AREA WITH STELCOR

OVERVIEW:
The 14-story Draper Hall, located between Metropolitan Hospital and the East River, combines new construction with substantial rehab to an existing structure. The tower footprint was expanded to allow for double loaded corridors, 201 apartments, and a community center for the city’s underserved seniors.

The project was originally spec’d with 12 3/4” micropiles using the traditional installation method and limited access was a concern. Also, the owner needed the piles to be installed quickly in order to stay within the schedule. Furthermore, contaminated soils were present and the cost of removing spoils was a significant concern.

IDEAL Group worked with Posillico to offer Stelcor Drilled-In Displacement Micropiles as a cost saving alternate solution on this project. Faster install time meant the project stayed within the schedule. No spoils are created when installing Stelcor piles. This resulted in a significant cost savings. Installation in the limited access area was simplified because minimal equipment is needed to install Stelcor Drilled-In Displacement Micropiles.
