Sheet Piling Contractor Wins Second Sheet Piling Scheme in Newark, UK, as part of Aarsleff Ground Engineering’s Advent Day 20!
Severn Trent is investing £60 million over four years to upgrade Newark’s sewerage and water system to help protect homes from sewer flooding and provide a reliable water source for decades to come. In 2016, Nick Wallace from Severn Trent explained that more than 12 miles of old pipes will be replaced with new, larger ones. In May, Aarsleff worked on Sleaford Road in Newark, to construct a reception shaft to receive a tunnelling machine (1.5 metre diameter). There were 28No sheet piles installed.
As part of the same scheme, and for the same contractor BNM Alliance, Aarsleff has been asked to construct another sheet piled cofferdam on Harcourt Street. Aarsleff will install 46 No. sacrificial steel sheet piles, with pile width 600mm and 12.0m in length. There will be a retained height of 10.2m, forming the overall cofferdam. Again, Aarsleff’s work will facilitate the installation of a slightly smaller, 1200mm diameter tunnel.
As Aarsleff will be piling in the middle of a residential street, Aarsleff will drive the sheet piles using an ABI leader rig with pre-augering taking place in advance of main works where we will utilise a Silent Hydro pile press to reduce the noise and vibration. A 50-tonne capacity crawler crane will be employed, operating at a maximum 6m radius to unload and handle piles and hammer.
Aarsleff Ground Engineering is expected to be on site from the 22nd January 2018.
Aarsleff’s Senior Technical Estimator Ashley Carter said:
“It is a great endorsement of Aarsleff’s work that we have been awarded our second contract for the same scheme in Newark, just 7 months later. There are around 400 homes in Newark that are currently at risk of flooding, demonstrating just how important sheet piling projects like this are in future-proofing our infrastructure and communities.”
