H & B collected a set of angles and reflectorless distances to each joint location of the tower as to ensure the location of each structure joint. While in the field, our crews located the same joint from multiple locations to have redundancy in each location which insured a tighter precision of measurement at each location on the structure. • Once the field surveying was complete and the integrity was checked in the field, the data was checked by a licensed professional and the data was processed utilizing Carlson Survey Software. This data was imported into a spreadsheet developed by H & B to calculate the twist and plumbness of the structure based on the calculation sheet provided by Motorola Communications.

3. Project Data Sheet – High Definition Scan of High Wall at Leesburg Quarry Location – Leesburg Virginia Our Work • H & B Surveying and Mapping, LLC (H & B) was requested to provide conventional cross-sections of a high wall at Luck Stone Corporation - Leesburg Quarry and a reflectorless image of the wall. The cross - sections were surveyed utilizing our Topcon GPT – 3103W reflectorless Total Station while our Topcon “IS” image Station was robotically collecting thousands of points on the high wall for additional engineering analysis. • How the project was complete – • The Topcon “IS” image station was set up and collected panoramic images of the wall and then was set up to collect survey grade points on a 1’ by 1’ grid. • While the “IS” was collecting data, our survey crew established additional baseline points where the actual surveyed cross-sections were to be gathered at approximately 90° to the face of the wall. • One of our Licensed Professional collected information on the baseline points in our “Carlson CE – Data Collector”, then began collecting reflectorless survey grade points from the top of the wall to the base of the wall ensuring that all undulations along the wall would be gathered and process in Cross – Section format. • Once the “IS” completed the first image scan the “IS” was moved to the opposite end of the wall and a second scan was collected in order to have overlapping data. Finally an Third scan was collected in the middle of the base line to have additional redundant data. While the conventional survey was being collected the “IS” was collecting over 60,000 points with little or no additional work on the crews behlf. • All “IS” scan information was processed with “Image Master” and a point cloud of the data was delivered in .dwg format. • The conventional cross-section data was process utilizing “Carlson Survey Software”.
