Sheet Piling contractor Aarsleff Ground Engineering were awarded the sheet piling contract by Oakford Homes to facilitate the construction of a new residential development and underground carpark in Deanfield Avenue, Henley-on-Thames.
The main client Oakford Homes purchased the brownfield site in Henley-on-Thames for a highly specified development comprising a collection of 23 contemporary 1, 2 and 3-bedroom apartments. Acquired from a family-run removals firm ‘Wilkins of Henley’, the site is opposite the Henley College and within easy walking distance of the shops and restaurants in the thriving town centre, the railway station and the iconic River Thames.
Aarsleff Ground Engineering were on site for 7 days, installing 88No AZ18-700 steel sheet piles of maximum length 10.0m to form a cantilever retaining wall approximately 61 l/m. Piles were driven to approximately 800mm above the existing platform level with its ABI tm14/17 leader rig with a 22VV (variable monument) vibrio hammer. The wall, deemed as a highway structure, had to be designed to resist highway loading, with a retained height of 3.0m.
Aarsleff’s sheet piling will also facilitate the construction of underground parking, to which the sheet piles will be exposed. Aarsleff’s Construction Supervisor Joseph Mills said: “This was a great project, and exceeding our client’s expectations, we finished 4 days ahead of schedule”.
