1 UAV APPLICATIONS IN ENGINEERING Presented By Wohnrade Civil Engineers, Inc.

2 UAV BUSINESS STARTUP March 31, Obtained DJI Inspire 1 Unmanned Aerial Vehicle (UAV) FAA requires Certificate of Authorization (COA) and Section 333 Exemption for commercial use of an Unmanned Aerial Vehicle (UAV) June 16, Received our Section 333 Exemption and COA from FAA Exemption and COA are valid for 2 years

3 FAA OPERATIONS AND PROCEDURES Must maintain Visual Line of Sight using Visual Observers Monthly reporting to FAA representative required Must file a Distant Notice To Airmen (D-NOTAM) prior to each flight Operations limited to feet Above Ground Level (AGL) Pilot in Command (PIC) must hold either an Airline Transport, Commercial, Private, Recreational, or Sport Pilot certificate

4 NO FLY ZONES Category A International Airports mile radius Category B Municipal Airports mile radius Inspire 1 will not fly within Restricted Zones Boulder

5 THE DJI INSPIRE 1 UAV Camera - 12 megapixel camera mounted to a stabilizing Gimbal Video - 4K at 30 frames per second GPS Dual Positioning - using multiple GPS navigational satellites Speed - Up to 50 MPH Range Approximately 1 mile Flight Time - Approximately 1 hour Flight Controls - Dual controllers using the DJI Pilot App

6 UAV CAPABILITIES Precision Agriculture Monitor crop health and nitrogen levels Mining Prepare volumetric calculations for determining company assets or planning site optimization Engineering Prepare precision geo-referenced surface models for engineering design Construction Monitor the progress of a construction project Architecture Prepare 3D renderings of buildings and sites, and thermal imaging Real Estate Create marketing videos for residential and commercial properties Aerial Utility and Infrastructure inspection And more

7 APPLICATIONS IN ARCHITECTURE Architectural Photography offering different point of view to highlight design features Useful for marketing purposes Thermal Imaging for detecting heat loss from buildings 3D Site and Building Rendering using photogrammetry

10 WOHNRADE CIVIL TEAMING PARTNERS DroneMapper A Colorado based company specializing in the generation of precision geo-referenced orthomosaics and Digital Elevation Models from aerial images obtained by UAVs and/or manned aircraft DroneDeploy A startup company based in San Francisco that develops UAV mapping applications for agriculture, construction, and mining CAD-1 An Autodesk authorized training center based in Thornton, Colorado Integral Consulting, Inc. An international science and engineering firm providing multidisciplinary services in the fields of health, environment, technology, and sustainability with offices in 13 states.

11 DRILL GREEN 35-ACRE SITE Located in Weld County, Colorado, approximately 4 miles north of Fort Lupton. Currently used for storage of oil and gas equipment Mission Planning and flight execution done manually Digital Elevation Models (DEMs) and Orthomosaics prepared by Drone Mapper using photogrammetry (with 204.jpg images) to survey level accuracy Files are georeferenced using surveyed Ground Control Points (GCP) in Universal Transverse Mercator (UTM) NAD 83 real-world coordinate system DEM s and Orthomosaics are delivered in a.tif file format High and Low resolution Point Clouds are delivered in a.ply file format

12 DEFINITIONS Photogrammetry - The use of photography in surveying and mapping to measure the distance between objects. Hundreds of.jpg images are stitched together to provide a stereoscopic view Ground Control Points (GCPs) - Surveyed points on the surface of the Earth of known locations and elevations, used to geo-reference aerial imagery Geo-reference - The process of associating a physical map or raster image of a map with spatial locations, such as GCPs Ground Sample Distance (GSD) The distance between two consecutive pixel centers, as measured on the ground. The smaller the GSD, the higher the image resolution will be.
