John Sisk & Son

Sisk is an innovative, international construction and engineering business with a long-term vision. Sisk employs over 2,500 people and is Ireland's leading provider of construction services with extensive operations across Ireland, the United Kingdom and mainland Europe with the track record, scale and capacity to successfully undertake large, complex multidisciplinary programmes. Sisk is recognised by global clients as a world leader in safe delivery.
Sisk delivers projects in sectors such as Data and Technology, Semiconductors, Pharmaceutical and Life Sciences, Infrastructure, Transportation, Healthcare, Commercial, Residential, Retail, Industrial, Leisure, Education and Energy.
Sisk offers a life-cycle approach to construction from planning and offsite construction, through delivering and fitting out a project safely and sustainably with technology as a key enabler and then working with clients to help manage and maintain buildings efficiently throughout their lifespan.
Our purpose is to create places for future generations. We take inspiration from our founder John Sisk, who was driven by a keen sense of public service through the early projects that were delivered by the business - schools, libraries, churches etc. Throughout our history, we have created legacies within the communities where we work, instilled by our core values of Care, Integrity and Excellence.
We have been in existence for over 165 years, and we want to continue to have a positive impact on future generations to come.
