Together they will contain 66 affordable housing units. **CHALLENGE:** Originally, 1.75” Helical Pulldown Micropiles were spec’d for this project. [IDEAL Group](https://www.idealfoundationsystems.com/) and Richard Anastasio partnered to provide an alternate solution using [STELCOR Drilled-In Displacement Micropiles](https://www.idealfoundationsystems.com/stelcor/). Time constraints and tight site access also weighed on the decision to use STELCOR. **SOLUTION:** Two full scale STELCOR load tests were performed by Procomm Systems and were successfully completed to NYC Building Code standards, at a 23% greater load. The STELCOR test pile’s produced a ***TOTAL NET SETTLEMENT OF .118 INCHES and .072 INCHES.*** Those net settlement results are not typos. They accurately tell the story of how STELCOR is producing astonishing results.

Installation was completed in 7 days and penalty fines that would have incurred were avoided. The pile count was reduced by 36% [**VIEW/DOWNLOAD PRINT VERSION**](https://www.idealfoundationsystems.com/hubfs/CASE%20STUDY/BROOK%20AVE%20CASE%20STUDY.pdf) **[![](https://www.idealfoundationsystems.com/hs-fs/hubfs/Imported_Blog_Media/Brook-Ave-STELCOR-Procomm-8.jpg?width=576&height=308&name=Brook-Ave-STELCOR-Procomm-8.jpg)](https://www.idealfoundationsystems.com/hubfs/Imported_Blog_Media/Brook-Ave-STELCOR-Procomm-8.jpg)[![brook ave apartments architect rendering](https://www.idealfoundationsystems.com/hs-fs/hubfs/Imported_Blog_Media/brook-ave-apartments-architect-rendering.jpg?width=576&height=308&name=brook-ave-apartments-architect-rendering.jpg)](https://www.idealfoundationsystems.com/hubfs/Imported_Blog_Media/brook-ave-apartments-architect-rendering.jpg)** **INSTALLER:** Richard Anastasio/Procomm Systems Phillipsburg, NJ **GENERAL CONTRACTOR:** YUCO Builders, LLC New York City **ARCHITECT:** Bong YU PC Engineering And Architect New York City **STRUCTURAL ENGINEER:** Bong YU PC Engineering And Architect New York City **LOADS** 40 tons – 80 kips ultimate compression **SPECIFICATIONS:** STELCOR 1200 14” tip or drive plate 12” corrugated grout column 9” solid grout column 8” reverse auger 5.5” steel core .361 wall thickness 55 ksi **SOILS + EMBEDMENT DEPTH:** View boring logs **[HERE](https://www.idealfoundationsystems.com/hubfs/CASE%20STUDY/BROOK%20AVE%20%20BORING%20LOGS.pdf)** 28’ **TIME FRAME:** Completed within the 7 day time frame ![Brook Ave STELCOR -
