The new facility is bound on two sides by the Maspeth Creek and Newtown Creek Waterways, both of which are EPA designated superfund sites. The foundation for the new structure consists of closed end steel pipe piles, driven to a depth of 80 feet below ground surface. Underpinning worked closely with the client and geotechnical engineer to complete the load testing program and install the driven piles on schedule and under budget.
