The Battery Park City Authority selected an Urban Engineers-led team to provide construction management services for the third phase of the Authority’s Pile Remediation Project. The $8 million contract began in June and will continue through October. Pile remediation entails pressure washing 650 square concrete piles, installation of fiberglass jackets, and filling the space between with an epoxy grout. The remediation should extend the service life of these structural support piles for many years.
The piles are hidden from view 10 to 40 feet below water and under a concrete deck structure in the Hudson River’s harsh salt-water environment. Assisting Urban in this assignment are AIA Engineers (MBE) and Armand Corporation (WBE) who are providing diving support and schedule analysis, respectively. Urban is providing project management, resident engineering, and document control.
Battery Park City was constructed in the mid-1970s following the original World Trade Center towers. Existing timber finger piers were demolished and over three million cubic yards of fill material from several nearby construction projects were placed along the lower west side of Manhattan to create 92 acres of new land.
Development has included office buildings, restaurants, shopping, a mega-yacht marina, and high-rise residential, which are all interconnected by a highly utilized public park. Coordinating construction activities to minimize disruptions is a critical element of the project. In order to protect the Hudson River’s wildlife, environmental permits were issued that include a work restriction from November through April. Implementing these repairs on schedule will be a key challenge.
