USA Ltd carries out topographical drainage surveys as part of an overall investigation of the drainage in an area or site. Our experienced topographical surveyors use the most up to date GPS system or in areas of heavy construction or dense tree cover a total station. This allows the drainage assets to be positioned to Irish National Grid and the inverts of pipes to be measured to Ordnance Level Datum.

The GPS data points can be used to create AutoCAD drawings or can be imported into InfoNet to aid in the development of a drainage network.
