Sisk Moves Staff Into New Retrofitted Dublin Building

Sisk, Ireland’s largest construction and engineering firm, has relocated over 200 of its staff to a newly retrofitted building at Citywest Business Campus in Dublin.

Following the retrofit, its new headquarters has achieved an energy rating of A3, an improvement from D2. The new offices were officially opened by An Tanaiste, Michéal Martin. The facility features 18 Electric Vehicle charging stations and includes a state-of-the-art gym. Additionally, the building has solar panels installed on the roof, an external air source heat pump and VFF air conditioning.

The retrofit project was complete by over 150 Sisk staff and supply chain partners and by adopting a circular economy approach to materials during the construction phase the project was able to save approximately €132.5k.

The most significant factor in carbon savings stems from upgrading an existing building rather than constructing a new one from the ground up. Typically, the structure, shell and core of an office building contribute over 70 per cent to its total carbon footprint. In this fit-out, the reuse of carpet tiles, raised access floors, ceiling tiles, and external paving resulted in a 17 per cent reduction compared to a scenario involving all-new materials.


The building is a full 'Digital Twin' building, this innovative solution will enable Sisk to operate and manage the energy and occupancy rate of the building and will be done remotely by Sisk facilities management company, SENSORi FM.

Paul Brown, CEO, Sisk said: "Our new retrofit HQ has been a huge undertaking and now we have a new home that is reflective of our modern business, we’re no longer ‘just’ builders, but trusted construction experts. Our new HQ demonstrates our key strategic priorities including, People & Culture, Net Zero, Digital Transformation and (MMC) Modern Methods of Construction. While this marks a significant change for Sisk, upholding the values of our founder John Sisk is essential that we look after our people and give them an environment fit for purpose, where they can thrive in their respective careers. Our message is clear, we have been in business for 165 years and we want to continue to have a positive impact on future generations to come."

The Tánaiste said: "The Tánaiste said: "I am delighted to officially open Sisk’s new head office in Citywest Business Campus today.

"This state-of-the-art facility is a retrofit building that has been upgraded from a BER Rating of D2 to A3 and exemplifies what we want to see more of throughout industry as we work towards our retrofitting and climate goals."
