The project

Data centre, Republic of Ireland

This project involved the construction of a new large data centre located in Clonee, Dublin for a global technology company.

This project is a state-of-the-art data centre facility and is the latest building in a development of cloud storage centres for one of the world's largest technology companies. The scale of the overall development in the Republic of Ireland is substantial, with the entire site occupying 480 acres and will be one of the fastest and most cutting-edge cloud-based data centres in the world, storing and retrieving information for millions of social media users. This project occupies c.90,000 square metres within this development – the equivalent of almost 18 football pitches.

The Group is very familiar with the development of data centres in Ireland, having recently completed the design, fabrication and construction of a similar, smaller facility, providing 5,600 tonnes of structural steel, in April 2018. This current project is exactly double the size of the previous project with a total of eight data halls and an accompanying administration block. The building is a single storey beam and column braced steel-frame structure with a roof that supports a plant gantry platform with 17,500 square metres of galvanised open-grid grating with associated construction handrails. Also installed on the roof is 68,000 square metres of metal decking incorporating 78 plenum pods weighing up to 20 tonnes, which were pre-assembled at ground level and lifted into location on the roof of the building with large 750-tonne mobile cranes.

The design elements for this project included connection design, temporary works design and detailed BIM coordination with more than 300 items of electrical and mechanical equipment. Early in the project lifecycle, the Group's project teams were involved in pre-construction stages, which created a platform for influencing key aspects of the design.

This project consists of an extremely challenging design, fabrication and erection programme. Design and detailing began on the project in spring 2019 with a drawing office team of over 30 skilled colleagues working on the project at its peak. The on-site erection programme was based on 12 steel crews erecting up to 1,000 tonnes of steel per week.
