Nicholson Construction was recently awarded a $72.1 million dollar design-build contract to replace an existing force main from the Virginia Key Central District Wastewater Treatment Plant (CDWWTP) under Biscayne Bay Norris Cut to Fisher Island.
The project, which involves changing out the current 54-in. sewer force main for a 60-in. replacement, is set to last approximately 26 months. The main scope includes the installation of a precast concrete segmental tunnel, which will stretch more than a mile from the treatment plant on Virginia Key to Fisher Island.
The design-build contract includes planning, engineering, design, permitting, procurement, construction/installation, testing and the start-up of the replacement force main. Nicholson will act as the general contractor for this project, with subcontractors including award-winning tunnel-design firm Arup, and various local sub-consultants and subcontractors.
Nicholson was among the three firms selected to bid on the project out of the six who intended to prequalify. “There were a lot of really strong firms bidding on this project,” said Laurent LeFebvre, Executive Vice President, Nicholson Construction. “We’re happy to be working with Miami-Dade County again and we look forward to a successful project with them.”
The project is slated to start in early 2014.
