Station markers normally comprise special hardened steel survey nails with a centre dimple which are resin bonded into a suitable substrate, these are highlighted by the use of a stainless steel washer or hi-viz plastic marker with the station reference number engraved into it. Where no stable substrate exists, specialist ground anchor markers with a suitable station marker are used.

We have invested in specialist Leica GPS surveying equipment with “Smartnet” capability, giving a real time solution of position in Ordnance Survey National Coordinates.

A survey station can be located with just one reading or for additional accuracy, a series of readings can be taken over several hours, and the average x, y and z result obtained.

We provide clients with a certificate for each survey station giving its OSGB36 Easting, Northing and Height, a photograph of the station and measurements taken to local features to enable the station marker to be located and where possible, reference bearings to local features to give a quick set-up at that station, without having to set up a target over an adjacent station.
