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.SIAC offers both public and private sector clients a comprehensive range of services across all areas of construction and has significant operations in both Ireland and the UK.
