John Sisk & Son’s revenue of just under €1.4bn sees it top this year’s ‘Construction CIF Top 50 Contractors’. In 2019, Irish operations accounted for €728m of turnover, with the UK and Europe accounting for €668m. Sisk has a consistent record of excellence in project delivery, innovation and value creation across different construction sectors and markets, including commercial, residential, civil engineering, data centre and life sciences, and celebrated 160 years in business in 2019.

CEO Steve Bowcott says, “We are proud of the important role we play supporting key Irish Government policy objectives in the provision of social housing, schools and other public infrastructure. During the year, Sisk Living – the group’s social housing unit – commenced the building, with its partners, of 590 residential units as part of the Social Housing Bundle 1 PPP project.”


Mental health continues to be top of the agenda in terms of wellness of its staff, with Sisk achieving the Ibec The KeepWell Mark™ in 2020, the culmination of three years’ hard work.
