Installing CFA piles for a gas main bridge
Aarsleff Ground Engineering has recently completed piling for a new substation as part of the Triton Knoll Offshore windfarm project in Bicker Fen, Boston.
The project saw Aarsleff install 8no. 600mm diameter CFA piles of 15m lengths, which were located either side of the gas main. CFA piles were specified due to minimal vibrations it creates as
the piles are being installed. Siemens then laid a concrete slab to create a bridge over the gas main and prevent any future damage from service vehicles and machinery driving down the access road.
Aarsleff Ground Engineering previously installed over 1500No. 200mm and 250mm square precast concrete piles in April for the foundations of the substation buildings and equipment. Subsequently, Siemens awarded Aarsleff the piling works for a gas main bridge that crossed the 3.8km access road.
Aarsleff’s senior contracts engineer Simon Cottington, who managed both piling projects said,
It has been a pleasure to work with Siemens again at the Triton Knoll Substation. This project was also the debut of our new Soilmec SF50 piling rig which allows us to install CFA piles up to 19m lengths.
