2 Opus have utilised our own UAV fleet since They are one of a range of technologies used to enhance our core services. cover photography - richard.barclay@opus.co.nz 2

3 Welcome to the game-changer! In an ever-changing world, embracing new technologies, is key to offering innovative solutions and services to our clients. One such technology is small, low-cost UAVs. Opus has utilised it s own UAV fleet since 2007 for surveying civil, geotechnical, infrastructure, environmental and many other disciplines. For our clients, low-cost UAVs provide valuable information on otherwise inaccessible work sites. They also have major benefits for response teams - in terms of health & safety (by limiting human exposure). In combination with survey and post-processing software packages UAVs can create accurate 3D models of a disaster site allowing the generation of base plans and cross sections. In the face of natural adversity Opus UAV fleet can be a game changer in our safety conscious world. Low altitude aerial photograph captured by UAV UAVs are small in size and do not get in the way of response operations and provide data (imagery/video) that is almost instantaneous. 3

4 UAV services overview UAV Outputs / Applications Aerial photographs Ortho mosaic image High definition video capture Digital terrain/surface model Volume calculations Slope analysis Data analysis Marketing Emergency response and natural hazard assessment Staging animations/design visualisation Visual impact assessment Corridor access routes River and coastal erosion monitoring Vegetation clearance surveys Health and Safety Gather data remotely and avoid exposure to hazardous areas Avoid the use of abseiling, scaffolding or cherry pickers We operate under the terms of current CAA legislation Why use a UAV? A fast and efficient way of capturing large amounts of detailed information Less down time for plant and equipment, jobs can be completed in hours not days Cheaper, faster and safer Able to capture current condition and accurate 3D model of site Benefits Reduce site time compared to traditional survey methods Higher level of detail = better quality results Reduction in number of return visits if further detail required Minimum disruption to site operations Non-contact data capture 4

DJI Phantoms (Quadcopters) QUAD COPTER CAMERA MOUNTED GPS TRACKING REMOTE CONTROL Deployment of Opus UAV DJI Inspire Pro (Quadcopter) What is the process? QUAD CAMERA GPS REMOTE COPTER MOUNTED TRACKING CONTROL DJI Matrice 100 The structure/area is identified QUAD COPTER CAMERA MOUNTED GPS TRACKING REMOTE CONTROL The data is collected by traditional survey of control points and UAV photography DJI Matrice 210 Key-point matching and calibration to register images captured from UAV The model is created in form of 3D point clouds, DSM and DTM s Ortho mosaic image created Data then exported into third party software for design/analysis QUAD CAMERA GPS REMOTE COPTER MOUNTED TRACKING CONTROL Topodrone TD100 CAMERA GPS REMOTE FIXED MOUNTED TRACKING CONTROL WING 5

7 Waiuta - Prohibition Ball Mill Highly contaminated site requiring detailed site survey without access. We produced a 13mm resolution aerial orthomosaic image and detailed digital terrain model very quickly. A happy client and no one got hurt! Ortho mosaic image Part 102 official certification SH 73 - Arthurs Pass Rock Shelter To assess loadings on the roof of the rock shelter we needed to survey the quantity of debris. The only solution that did not require expensive and time consuming rope access was UAV, with very comprehensive results. Digital surface model Opus International Consultants are a CAA Part 102 Certified UAV operator, who have qualified pilots from Invercargill to Whangarei. The Part 102 certification gives confidence that Opus UAV program and pilots adhere to a high and strict standards when it comes to operating in a professional and safe manner. The certification requires a strict maintenance program for hardware and regular training and testing of pilots. A growing number of health and safety conscious clients are specifying Part 102 certification as a requirement for those providing UAV services to ensure they are doing all they can to keep people safe. Our Part 102 exposition allows four key elements outside Part 101. These are, operation: Within 4km of aerodromes Above 400ft above the ground SH 1 - Auckland Motorway Providing updated high resolution aerial imagery for GIS asset management after the completion of construction projects, such as the bus lanes on the Auckland motorway Above persons and property without requiring permission At night time This gives us the flexibility to provide solutions to a wide range of situations. 7
