VolkerStevin were awarded the Middlewood locks restoration project which consisted of restoring a section of the existing Manchester, Bolton and Bury canal where it passed through a derelict area of Salford.
The canal in this area had previously been filled to make way for new industry and later on the construction of the Manchester Ring Road. However, since the demise of these industries the area has become derelict and has been ear marked as a prime development opportunity.
When the ring road was constructed the project team had the foresight to design and install secant piling along the line of the canal and construct a suitably reinforced concrete roof slab. This meant that the option to reinstate the canal at a later date was retained.
The section of canal being constructed was approx. 500m long and will be used as a catalyst to develop the surrounding area.
This complex project involved excavation and clearance of old foundations and services and the restoration of locks, the realignment of canal channels, tunnelling under one of the busiest roads in Manchester City Centre, the construction of new basins and the construction of what will be the deepest canal lock in the country.
The project runs from the canal's interface with the River Irwell, where we installed a cofferdam and managed to retain the existing lock structure.
