Arrigan Geo Surveyors is the trading name of Land & Site Surveys Ltd., a company formed in 1992 to provide a competent surveying practice for the Galway area. The company office is a modern ground floor office situated at the entrance to the Technology Park - beside Ballybrit Race Course.

Because we are a local company, and hail from the city, we have a great rapport with many local business people, particularly in the construction and legal sector. Over the last fifteen years the company has developed into a highly acclaimed enterprise and in that time many businesses came into being with Arrigan Geo Surveyors at their side, looking after their mapping needs.

Currently the business runs with Brendan Arrigan overseeing all aspects of the work. Mary Arrigan is company secretary, and oversees the finances. There are two highly
experienced field crews in operation at present, and one additional person completes the office work. Brendan began his surveying days with the Ordnance Survey of Ireland – and always was intrigued with the technology and the mathematical precision of the work. It is difficult to keep pace with the changes taking place in mapping and surveying technology, and it always amazes him to see the progression over the centuries from plane table mapping using chains and interferometers, to theodolites and subtence bars, to electronic distance measurement and aerial surveys from photography followed by total stations and now accurate GPS measurement from satellites. Further advances are under way with the advancement of satellite imagery and mapping from space. It will be interesting to see what comes next but it is believed that GIS (Geographical Information Systems) will also become very important.

Our clients range from County Councils, Local Airports, Engineering and Architectural Consultants, Building Contractors, Environmental Consultants, Plant Hire and Quarry Companies, Auctioneers, Solicitors and the General Public.
