Founded in 1913, SIAC's business has grown through our reputation for delivering quality projects that always meet and often exceed our clients' expectations. This philosophy continues to drive our business forward today, as, for example, when we completed the €300 million M4/M6 motorway - 10 months ahead of schedule.
We are now one of Ireland's largest contractors and have built a strong reputation and growing business in Ireland and the UK. Through a programme of alliances with major international civil engineering contractors and specialist contractors, we are able to undertake multidisciplinary projects of scale and complexity.
The diverse range of construction services provided by our individual Businesses are detailed in the "Services" section of this website. Alternatively, select "Projects" to view the work we have done in a wide range of client industries.
