Installing a cofferdam for a new outfall structure into the off Water Lane in Newark.
Aarsleff Ground Engineering have completed on site installing and extracting a sheet piled cofferdam on Water Lane in Newark, as part of waste and water improvements in the town. Severn Trent’s £60 million investment to upgrade Newark’s sewerage and water systems will help protect over 400 homes that are currently at risk from flooding.
The project was Aarsleff’s fourth sheet piling contract on the scheme, having previously installed sheet piles for a cofferdam on Harcourt Street and two sheet piling projects on Queens Road, all which were awarded and completed within a two-year period.
Whilst on site, Aarsleff utilised their vibratory hammer rig to install 254No. L605 temporary sheet piles of 10m to form a cofferdam that extended into the river Trent.
Aarsleff’s Senior Technical Estimator Ashley Carter said,
“It is a great endorsement of Aarsleff’s work that we have been awarded another contract for the same scheme in Newark.”
“We have previously installed Cofferdam’s for the scheme, but this one involved working over the River Trent, retaining the water for Nmnc to replace a new outfall structure.”
Aarsleff commenced sheet piling works at the beginning of January, with the install taking 6-weeks to complete. The extraction of the piles took place 5-weeks after installation of the piles.
