The UK’s largest long reach excavator, with a maximum reach of 27m, was employed for this two phase project which also relied heavily on Land & Water’s high quality plant to help minimise the risks caused by working on temporary tidal platforms.
Dredging International Ltd required the use of Land & Water’s specialist equipment to complete temporary measures that had previously been put in place.
- Recovery of 115,000 tonnes of temporary rock armour revetment to facilitate the removal of a temporary sand berm (in phase two) originally constructed to support the quay wall construction
- The rock was stored for later use on the project’s permanent revetment
- Two Land & Water triple boom 25m reach excavators equipped with DGPS equipment ensured all rocks recovered and working areas adequately swept – with rock recovery extending to -6.5m LAT on the 1:3 slopes
- Recovery of 1,000,000 tonnes of sand and gravel from the tidal berm
- Largest long reach excavator required to support the tidal and complex logistical project
- Sand and travel transported up to 2.5 miles by articulated dump truck and re-used in an integral business park construction
- The project was completed for Dredging International Ltd
- The works were completed January – December 2012
- Specialist marine works
- UK’s largest long reach excavator (ZX850) reaching 17m (capable of 27.5m in different configuration)
- Two triple boom 25m reach excavators with DGPS equipment
