A joint venture (JV) of OHL USA, a subsidiary of Spanish construction firm OHL, has secured a contract worth $187m to replace outfall pipe at the Bergen Point Waste Water Treatment Plant in New York, US.
The contract has been awarded by Suffolk County Department of Public Works. The JV partners include Posillico with 40% interest and Seli with 20% stake. OHL USA also holds 40% interest in the JV.
OHL said that this is the largest construction project in Suffolk County in several decades and OHL’s first project on Long Island.
Pursuant to the contract, the team will be responsible for the construction of a 14,200ft and 120-inch inner diameter tunnel, which will be built to replace the current prestressed concrete cylinder pipe (PCCP) outfall pipe.
The pipe carries millions of gallons of treated wastewater, connecting the Bergen Point Wastewater Treatment Plant to the Barrier Island under the Great South Bay.
The new tunnel will be excavated and concurrently lined using precast concrete segment rings. It is expected to address the concerns of potential failure of the current pipe and will have a longer lifespan.
The team has chosen TBM for the excavation of tunnel and selected 48-inch wide precast segment liners for the project.
Furthermore, the JV will also deliver the ancillary works within the tunnel including the installation of new piping and valving, associated plumbing, HVAC (Heating, ventilation, and air conditioning), and electrical work.
Currently, OHL is delivering many construction projects in the New York area including Superstorm Sandy rehabilitation work on the Canarsie Tunnel and Queens Midtown Tunnel.
The construction firm also completed other projects in New York, including the renovation of the 63rd and 72nd street subway stations for the new Second Avenue subway line, renovation of Corbin Building; the refurbishment of the South Ferry Station Terminal Complex; and the revamp of Culver Street Line viaduct.
