- The company's latest contract win follows recent selection for the manufacture of 18 sets of moulds, a double carousel production facility and associated handling equipment for the 15km of twin running tunnels of the North West Rail Link mega-project in Sydney, Australia. The client there is the contractor JV Thiess/John Holland/Dragados.
- Six sets of moulds will be delivered to Bay State Precast LLC for the Anacostia River Tunnel, part of the wider Clean Rivers Project in Washington DC. Each ring is composed of five standard and two key segments to an exterior diameter of 7.62m, with individual segments measuring 1,829mm x 305mm. The segments will be manufactured in the Bay State Precast LLC factory located at Brandywine, near Washington DC. The CBE carousel that will accommodate the new moulds has already been used successfully in production of the Blue Plains tunnel segments, including the anchored gasket technology. Before casting, the gaskets are directly installed inside the segment mould, instead of using a long gasket gluing procedure.
- Both the 3.84km Anacostia and 7.2km Blue Plains tunnels are part of the Long Term Control Plan of the District of Colombia Water and Sewer Authority (DC Water) to reduce combined sewer overflows into the Potomac and Anacostia Rivers. The US$253.9 million design-build construction contract for the Anacostia Tunnel was awarded to the Impreglio/Healy/Parsons JV in 2013, with construction scheduled for completion in March 2018.
- CBE's scope of supply to construction of the new subway Line B of the Rennes Metro in Brittany, France, comprises five sets of segment moulds to an exterior diameter of 9.1m, a width of 1,300mm and 2,000mm and a thickness of 400mm. The concrete rings will have a configuration of four standard, two counter-key and one key-stone, and will line the 7.5km long tunnel part of the metro. Additionally, CBE will design and install a production facility close to the tunnel shaft entry at Bruz. The production rate is specified at nine rings per day. TBM excavation is scheduled to start in November 2014.
- CBE Group, which to date has delivered more than 350 precast facilities worldwide, 116 carousel type factories, and 12,000 segment moulds, has production sites in L'Ile Bouchard, France, and Yangling in China. It delivered moulds and precast facilities for construction of the first subway line in Rennes back in 1997.
