The team is finishing removing the sheet piles that made up the cofferdam. The cofferdam is the temporary area of land built out into the river with metal perimeters to give the necessary space for construction of the super sewer.

The team is also working on the architectural and landscape features of the site, including cladding the mechanical and electrical kiosks in brickwork, which includes an artwork by Florian Roithmayr.
