Landform Surveys were approached by a client working on a major development in Teesside to support with a control survey to gather measurements and data. The project required a precise check on existing control stations periodically to ensure accuracy which was critical to the development.
A control survey plots horizontal and vertical positions of points to establish reference points to be used throughout the project.
Traverse was undertaken using a Trimble SX10 along with a precise levelling loop. The Trimble SX10 is perfect for high-speed 3D scanning and imaging due to its unrivalled accuracy and measurement performance. It is also a highly accurate total station with one-second accuracy.
We gathered some great results. The traverse observations were adjusted using least squares and the misclosure was over 1 in 1,000,000.
