The PICUS provides non-invasive testing of the tree structure through ultrasound technology. This specialized testing is conducted by ENSPEC Environment and Risk once an initial visual assessment is completed and a concern is raised over a suspected fault in a tree structure. The test will produce an image of the structure, mapping the sound wood. From this data, an accurate assessment can be made about the structure at this point and recommendations made on both suitability for retention and ongoing management requirements.
