Who we are


Archaeological Consultancy Services Unit (ACSU) was founded in 1992 in Drogheda, Co. Louth to provide a professional archaeological service to everyone from private individuals to building contractors and local authorities in an efficient and cost effective manner.


Since then our staff have been involved in some of the largest infrastructural projects ever carried out in Ireland with clients including state agencies, government departments, local authorities, construction professionals and private developers. We provide a fully comprehensive service covering all aspects of archaeological identification and mitigation. Using a partnership approach we provide solutions for your archaeological requirements. We have a proven track record over 20 years of completing projects within or under budget.


We are all too aware of the effects of a delay on development contracts and we are totally flexible with our resources and can accommodate and facilitate the most efficient and professional resolution possible.
