Progress

Belfast is built on an area of complex glacial and fluvio-glacial deposits, which are highly variable. These ground conditions created a number of challenges which required some complex solutions.

Advanced techniques have been incorporated into the construction process including major system formwork for the Terminal Pumping Station, Earth Pressure Balance tunnelling methods and sprayed concrete shell techniques for excavations in clay and rock.

A key project landmark occurred in April 2008, with the completion of one of the deepest tunnels. Stretching for almost a mile and 40 metres below ground this section of tunnel runs from Whitla Street to a proposed new high-tech terminal pumping station at Duncrue Street. The pumping station is capable of holding up to four million gallons of stormwater.
