One of the largest telecommunication companies in the world requires communication lines to be installed underneath the Hudson River connecting Brooklyn and Staten Island to expand its capacity in the area. The owner of the project has chosen design build as the method of choice for project delivery. Mears, one of the leading HDD contractors in the world, is leading the design build team to manage and facilitate the design, and permitting of the crossing and will install approximately 9,600 feet long 24 inch steel casing underneath the Hudson River. This paper describes the challenges faced in design and permitting phase of the project and how they were solved by using integrated team approach. The technical challenges included length of the crossing for the given pipe diameter, geotechnical conditions and available tight workspaces for the magnitude of the crossing. Many constraints of the project including client requirements and construction work window are discussed. The permitting challenge included involvement of multiple stakeholders in a congested city. The design build approach helped the project team to identify the potential construction challenges early in the project and come up with optimal solution to deliver a viable solution for the project.
