Winthrop Services

Winthrop’s specialist turnkey service covers the full range of requirements for data centre construction, from design to construction and commissioning. Clients can rely on the company to carry out all works, including civil and structural engineering, architecture, construction, mechanical and electrical services installation and commissioning.

Over the past few years, Winthrop has been one of the fastest-growing and most trusted companies in the Irish construction sector.

Anne Dooley, CEO, Winthrop, comments: “Our operations are engineering-led by people with a strong technical background. We take a solutions-based approach to meeting our clients’ needs.

“We are currently constructing multiple turnkey data centre projects in eight different European countries, equating to over 220MW of IT load.”

She continues: “Data centres are not complex building structures, but the mechanical and electrical installations are very complex. Our technical knowledge helps us drive projects. This gives us an edge when it comes to delivering projects efficiently and cost-effectively.”
