At BIRD, we have vast experience in carrying out topographic surveys, and it is the core of our business. Our surveyors use Total Stations, and Trimble R4 & R12 receivers to carry out surveys. These instruments are also capable of reflectorless measurement, which means we can survey previously inaccessible points. This is particularly useful for surveying heights and positions of buildings, which overlook development sites and produce streetscapes of adjacent building elevations.
We have also utilisedaerial UAV drone technology to produce ground terrain and topo surveys of large sites, and are presently evaluating this method for accuracy and cost-effectiveness.
