Senior Associate/VP, Langan

This presentation will discuss the development of a 14 story, 675,000-square-foot building supported by over 350 hollow-stem, cast-in-place friction piles with an average depth of 90 feet at a former Navy Yard dry dock in Brooklyn. This new building is the first as part of a major revitalization of a key portion of Brooklyn. The chosen pile type was the result of a value-engineering effort proposed by the contractor and replaced traditional caisson piles originally proposed during design. The talk will focus on the history of the site, the unusual subsurface conditions, and the impacts of these items on the pile construction. Details about a comprehensive axial‑compression load-test program will be discussed and some lessons learned and recommendations will be provided.
