bowmanconsulting.com <br />As part of an on-call contract with Martin County, Bowman Consulting per- <br />formed a specific purpose survey at Bathtub Beach. Bowman’s survey crews set <br />control every 400’ and located control with GPS. <br />Control points were set every 200-250. Bowman performed medium resolu- <br />tion scans with photos using the internal Leica C10 camera. A second scan was <br />taken using a Cannon external camera. The scan data gathered vertically at -45 <br />degrees to 180 and horizontally at 360 degrees. Challenges with this project <br />included obstructions from on-site construction equipment. Water also pre- <br />sented a challenge because its return is a void or a scattering of data points. <br />Bowman Consulting is contracted to conduct additional surveys at Bathtub <br />Beach utilizing the eBee Unmanned Aerial System (UAS) platform to docu- <br />ment beach improvements. This survey will result in producing high resolu- <br />tion digital imagery, a 3 dimensional point cloud, ground contours and asso- <br />ciated digital files. Bowman has been granted an exemption from the FAA to <br />commercially operate a UAS in the National Airspace. In addition to the ex- <br />emption Bowman applied to the FAA for a special Certificate of Authorization <br />to operate within a 5-mile radius of the airport. Once authorized, this portion <br />of the project will include setting survey control, setting aerial targets, data <br />collection utilizing the UAS, data testing and classification, data processing, <br />and a surveyor’s report. <br />Bathtub Beach Specific Purpose Survey <br />Martin County, Florida <br />Client <br />Martin County <br />2401 SE Monterey Road <br />Stuart, Florida 34996 <br /> <br />Michael O’Brien, PSM, CFM <br />p: (772) 288-5472 <br />e: michaelo@martin.fl.us <br />Contract Dates <br />6/2016 – Ongoing <br />Fee <br />$ 5,210 <br />Tab 2 <br />Specific Experience <br />Page 20
