A new construction, 5-story residential building in Astoria NY. Helical piles were originally specified for this project.
CHALLENGE:
The developer faced several challenges at this site. The biggest concern was the high water tables present. A redesign was issued, the loading was changed, and helical piles were rejected due to the high load restrictions placed on helical piles in the NYC metro area.
SOLUTION:
IDEAL teamed up with Rich Anastasio to offer Stelcor Drilled-In Displacement Micropiles as an alternative foundation solution. Stelcor Micropiles were a perfect fit not only from an engineering perspective, they were much more cost effective compared to alternative piles. After a 48-hour load test at full test load, there was essentially no movement. Engineers on site told the installer they had never seen a test that went that well.
