Information on our Surveying Techniques

At NCW Surveys, our team utilise a Total Station to establish highly accurate control across sites. This instrument plays a key role in setting out survey stations and tying all data into a consistent coordinate system. It allows us to verify key structural elements and ensure that measurements taken throughout the building aligns precisely with external control. The Total Station also supports us in checking the accuracy of the scan data and enhancing the overall reliability of the survey results, especially in areas where GPS is not viable.

To establish robust site control and capture external topographical data, we use our Trimble R12i GPS units. These high-spec GNSS systems enable the NCW Surveys team to record accurate coordinates for manholes, drainage runs, and other surface features, all tied into the national grid. With tilt compensation and exceptional satellite tracking performance, the R12i allows us to maintain efficiency even in areas with reduced sky visibility. This GPS data is essential in georeferencing the overall survey and mapping out external sewer infrastructure as part of the deliverables.
