We use leading field software to produce comprehensive and detailed drawings and studies. Our experienced CAD team use AutoCAD to produce clear and concise drawings that illustrate trees’ impact on buildings. They can also provide detailed Shade Analysis where appropriate to depict any shading issues that could be a concern on development sites etc. Our expertise in the use of this software allows us to produce results that are considered to be amongst the best in our industry.

Using the latest tablet technology with GPS along with the EzyTreev Tree Management System for data collection during site visits. This allows us to collect all the required information and accurately plot the position of individual trees, groups of trees, hedges and other important features in one movement. This technology also gives us the ability to upload topographical survey data or other background drawings for use in the field.

Ultrasonic decay detection to assess structural integrity of trees. The Picus uses a series of sensors strategically positioned around the tree to both send and receive sound waves generated by the tapping of the sensors with a hammer. Software then generates a tomograph depicting the condition of the wood as a series of colours dependent on the speed of the sound waves between the sensors.

Another great tool we have for detailed tree and decay assessment at Hayden’s is the IML PD500 Micro Drill is a calibrated micro drill which measures the resistance to the progress of a 500mm long, 2mm diameter drilling needle bit as it enters the tree. The results of each measurement are produced in graphic form displayed two colours; blue represents the feed rate and green represents the penetration resistance. The graph is read from right to left and can be interpreted to evaluate relative wood strength, decay pockets, variations in ring growth, structural condition of cell walls and tree responses to environmental conditions. We also print off a hard copy on site for assistance in assessing the data on site and explaining it to the client. The variation in resistance results in increases and decreases in the amount of torque applied to the drill shaft. By means of sophisticated mechanical and electronic sensors, variations in torque are translated into graphical output which depicts the internal conditions encountered by the drill at the specific point of drilling. Each of the drill tests undertaken is supplemented by a brief description of the analysis and discussed within the finished report. The IML PD500 Micro Drill is an invaluable tool especially when used alongside our Picus Tomograph to provide a detailed and valuable assessment of the structural integrity of the trees inspected.
