The tower footprint was expanded to allow for double loaded corridors, 201 apartments, and a community center for the city’s underserved seniors.   ![vlcsnap-2016-01-15-07h32m36s925](https://www.idealfoundationsystems.com/hs-fs/hubfs/Imported_Blog_Media/vlcsnap-2016-01-15-07h32m36s925-300x168-1.png?width=300&height=168&name=vlcsnap-2016-01-15-07h32m36s925-300x168-1.png)![IMG_20150619_131309](https://www.idealfoundationsystems.com/hs-fs/hubfs/Imported_Blog_Media/IMG_20150619_131309-300x168-1.jpg?width=300&height=168&name=IMG_20150619_131309-300x168-1.jpg) **CHALLENGE:** 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. ![vlcsnap-2016-01-14-14h44m52s333](https://www.idealfoundationsystems.com/hs-fs/hubfs/Imported_Blog_Media/vlcsnap-2016-01-14-14h44m52s333-300x168-1.png?width=300&height=168&name=vlcsnap-2016-01-14-14h44m52s333-300x168-1.png)![vlcsnap-2016-01-14-14h53m06s843](https://www.idealfoundationsystems.com/hs-fs/hubfs/Imported_Blog_Media/vlcsnap-2016-01-14-14h53m06s843-300x168-1.png?width=300&height=168&name=vlcsnap-2016-01-14-14h53m06s843-300x168-1.png) **SOLUTION:** [IDEAL Group](https://www.idealfoundationsystems.com/) worked with Posillico to offer STELCOR Drilled-In Displacement Piles 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 Piles. **[VIEW/DOWNLOAD GEOTECHNICAL REPORTS AND LOAD TEST RESULTS](https://www.idealfoundationsystems.com/hubfs/CASE%20STUDY/STELCOR%20-%20DC%20WATER%20&%20SEWER%20-%20Complete.pdf)** **OWNER:** SKA Marin Great Neck, NY **GENERAL CONTRACTOR:** Procida Construction Corp.
