CH2M is to oversee the design of repairs to around 3,500 steel piles that support Pier 40, in Hudson River Park, New York.
The 6ha pier is one of the Park’s most important commercial properties and includes sports fields, offices and parking.
CH2M produced a report two years ago showing that 57% of its steel piles were suffering from major to severe deterioration. It said the need for repairs was critical. The structure of the pier is a 247m by 247m pile-supported platform, which includes a two-storey shed, a public esplanade and a courtyard.
It is estimated the repairs will cost just over £76M and will start next year. A contractor is due to be appointed later this year. Funding will come via another development project in the park, which is yet to be signed off. The project will be delivered with Insight Civil Engineering. The first phase of the repair will take around six months and the design will aim to extend the pier’s life by more than 50 extra years.
