Rochdale Riverside - Multidiscipline Ground Engineering solution
Multidiscipline ground engineering package for new retail and leisure development.

Aarsleff Ground Engineering were awarded the contract at Rochdale to provide a multidiscipline ground engineering solution package for a new retail and leisure park, on behalf of main contractor Willmott Dixon. The £80m flagship project will comprise of approximately 200,000sq/f of retail and leisure shops, with a Next, M&S, Boots and Reel Cinema. Originally specified as a CFA and Sheet Piling Scheme, Aarsleff were able to convert much of the project into precast piles, with the addition of Ground Anchors and a King Post Wall.

Aarsleff installed a 152 lin/m King Post Wall for a new two-storey car park, for the M&S. With retaining heights up to 4.7m, the wall also provides level ground for a new access road which will be situated behind the wall. For the cinema, Aarsleff had to engineer a solution to allow them to pile adjacent to a live and running metro station whilst keeping it cost effective for the client, resulting in a combination of 43No CFA (Continuous Flight Auger) piles and 16 No anchor piles to a 17m depth. For the rest of the site, Aarsleff installed 302 No. precast concrete piles driven from 9m to 20m depth, keeping the costs down for the client but without compromising on the structure.

Aarsleff used prestressed concrete panels for the King Post Wall. The decision to use prestressed rather than reinforced precast concrete panels resulted in a high strength/size ratio, ensuring that units were lighted and thinner and provide more tolerance for the meander of the wall. Jamie Beard, Senior Building Manager at Willmott Dixon said “This solution was proposed by Aarsleff as opposed to a sheet piled wall. The finish of the Kingpost is excellent, and our customer is far happier with it as a product compared to a sheet piled wall.”
