WELL-ROUNDED DESIGN SUPPORT CREATES AN EFFECTIVE AND EFFICIENT SOLUTION FOR NEW RESIDENTIAL STRUCTURE
SCOPE OF WORKS: 143m of sheet pile wall from 3-9m
CLIENT: Hargreaves Contracting Limited
CONTRACT: Design and build
CONSTRUCTION PERIOD: June – July 2023
Aarsleff were contracted to install 143m of sheet piling for a new residential structure in Stockport, near Manchester. On the site of a former car wash, the development plans to create 73 one- and two-bedroom apartments and will aim to create affordable housing for local residents.
The provided cross sections of the building and proposed layout of the sheet pile wall were complex and meant our engineers needed to dedicate time to more deeply understand the scheme through conversations with our client and site visits.
It was initially proposed that the sheets be driven using a Movax attachment to an excavator, which is effective in soils of low to medium strength. Borehole investigations indicated a hard stratum of sandstone at 7.9m below ground level. To ensure the most efficient delivery, it was identified that designed pile toe level must be above this 7.9m level, which our design engineers achieved through an effective and economic design.
