Aarsleff Ground Engineering were awarded the piling works from main contractor Galliford Try PLC. The project will form part of a new Bio-Mass energy facility located on land leased from Associated British Ports (ABP) in the vicinity of King George Dock, Hull. The Bio-Mass Plant is part of an Advanced Thermal Treatment plan designed to process woodchip and biomass waste.
Specifically, Aarsleff designed and installed 667no 300/350sq precast concrete piles supplied in two segments interlocked with a full mechanical pile joint. The piles were founded within dense sands/gravels at 25 to 28metre piling platform level. Aarsleff carried out 3 preliminary static load tests which were undertaken during the initial week, followed by dynamic testing during numerous visits to site. Driven piles were installed within 18m of an existing brick culvert with vibration monitoring undertaken to ensure the levels of vibration did not exceed the limits of vibration imposed by Yorkshire Water.
Aarsleff were on site for 10 weeks with two of its Junttan PM20 Piling Rigs. Project commenced in June 2016.Download Case Study
