Chesham Data Centre

Keltbray delivered the full enabling and foundation package for a new data centre development on a complex brownfield site in Chesham.

The scope included the construction of contiguous and sheet piled retaining walls, large-scale bulk excavation and earthworks, installation of propping systems, piling and foundations, and the delivery of permanent drainage, ducting and underground services. Key works included a 250-metre contiguous piled retaining wall reaching heights of up to 12 metres, a 70-metre sheet piled perimeter wall, 80,000m³ of bulk excavation, and the installation of 1,200 CFA bearing piles.

Combining specialist geotechnical engineering, earthworks and foundation expertise, Keltbray successfully transformed the site into a fully prepared, structurally robust platform to support the construction of the future data centre.
