UAS Applications in Civil EngineeringPresented by:

WOHNRADE CIVIL ENGINEERS CORPORATE HISTORY Small Progressive Civil Engineering Consulting Firm based in Broomfield, ColoradoRegistered as a Colorado Corporation on November 4, 2002Certified DBE and ESB with CDOT, and Certified EBE, M/WBE, and SBE with the City and County of Denver Specialties include: land development, municipal projects, floodplain management and water resource design. Geographic range includes projects throughout Colorado, Illinois, Nevada, Nebraska, and WisconsinEmploy 2016 Civil 3D software and GIS

Transition, Now we have been working very hard over the past year and a half to develop efficient workflows when using UAS tech2

Certifications and Platforms

June 16, 2015 - Received our Section 333 Exemption and COA from FAAFAA requires Certificate of Authorization (COA) and Section 333Exemption for commercial use of an Unmanned Aerial Vehicle (UAV)Exemption and COA are valid for 2 yearsSeptember 30, 2016 Received Part 107 CertificationCertification is valid for 2 years

June- Section 333- Began for hireRules changed Part 107 operatorsFleet comprised of both multirotor and fixed wingBoth serve specific types of terrain, large and smallFixed wing developed by Jack Elson and colleagues at Blackswift Technologies3

Overall Cost to ClientFor Topographic Mapping

WCE unmanned aerial surveys save clients an average of 40% when compared to traditional surveying methods.

Because our work has to be survey grade we strive to collect data at the upmost level of accuracy7
