Thames Tideway Tunnel (TTT)
VolkerStevin has been appointed by Thames Water to carry out enabling works, in advance construction of the Thames Tideway Tunnel which will tackle pollution in the Thames.
VolkerStevin started work on the £23 million project which will involve numerous marine construction projects in the city. The work is all part of the larger Thames Tideway Tunnel project which will help the capital cope with growing demands on its sewerage system and improve the water quality of the river using combined sewer overflow interceptor structures.
Teams are currently carrying out works in Blackfriars to construct a new pier, lift and stairs to replace the Blackfriars Millennium Pier, where movement monitoring has been set up for three months on the river walls as well as vibration monitoring as a safety measure.
On the Victoria embankment, they are installing new moorings with steps and gangways for the Tattershall Castle restaurant boat. This will allow it to be moved upstream to free up a site required for the Tideway project.
Key activities on the project are; tubular piling, sheet piling, general works, pier pontoon installations, Blackfriars lift and stairs, dredging and scour protection.
A schedule has been set up for the works to be done around local school holidays and attractions timetables to reduce potential noise produced on site.
