Colt London 4 data centre

Colt has acquired a data centre site in Hayes to develop a data centre campus. The plan is to construct two data centre buildings and a 66kV substation. The aim of this development is to maximise the site's potential while also showcasing an example of environmentally aware urban regeneration. When completed, Hayes will become the largest data centre in Colt's London portfolio. It will offer approximately 57MW of IT power, spread across a gross site area 49,000m².

The first building on the campus, London 4, has nine data halls with critical plant infrastructure, an administration block, green walls, and screening panels for the generator gantry areas. The data centre has been designed to achieve a BREEAM Very Good rating, focusing on reducing water consumption and on -site carbon dioxide emissions. Materials used in the building have been carefully selected to ensure low environmental impact throughout their lifecycle, emphasising circularity. The project aims to achieve a 95% reuse, recycling, and recovery rate for demolition and construction waste.

Construction work on the first building began on a shell and core basis in the last quarter of 2022. IsG Construction is the Principal Contractor, while Cundall has been providing multi-disciplinary engineering consulting as the Client's Design Representative (CDR). Cundall has been peer-reviewing the design as it has progressed through each RIBA stage gate. All reviews, issues, and quality reports are managed through a platform with BIM360.
