A (Not so Light) Light Move!
The Lead-in-Light was originally constructed in the nineteenth century and served as a guide for shipping pilots to navigate their way through the difficult and treacherous river estuary. It is constructed entirely of cast iron and weighs some 20 tonnes. Originally several similar structures were in use around the harbour estuary but this is one of the last. The structure is still intended to be used for navigation purposes but, over the years, the line of vision has become increasingly obstructed by a series of structures erected in the near vicinity.
Geostructural Solutions was commissioned to move the Lead-in-Light complete and intact some 20m. They finished the project on time and on budget in December 2013. A crane move was considered impractical so the brittle cast iron structure was temporarily cradled in a grillage of structural steelwork and hydraulically lifted/moved to its new location.
