Unmanned Aerial Vehicles (UAVs), commonly referred to as drones, have become indispensable tools in the engineering industry by improving the accuracy of mapping, measurement, inspection services and 3D modeling, with three very important advantages:

  1. Greater Safety: Provides access to areas where it may be impossible or dangerous for engineers to perform thorough close-up inspections, e.g. large petroleum tanks, water tanks, building façades, beneath or around bridges/infrastructure, uncompleted building superstructures, condemned or failing structures, etc.
  2. Greater Efficiency: Allows inspections of large areas for photographic/video documentation, thereby enabling engineers and clients to review data in the office or in the field.
  3. Lower Costs: Reduces inspection costs, accurately estimates soil “cut and fill” volumes and provides estimates to the contractor before they turn into costly change orders.

D&B’s drone/UAV capabilities can support a variety of projects across their entire lifecycle, from planning/design to construction and inspection. Our experienced team of FAA-licensed drone pilots and our comprehensive drone/UAV systems are ready to support all projects. Enhanced visualization facilitates communication of project benefits and challenges and increases inspection efficiency. This provides more meaningful data, including high-resolution 3D modeling and simulations. D&B drone/UAV capabilities can cover multi-acre sites while continuously capturing GPS-tagged high-definition (4K) video and/or still photographs. Through the use of linked ground control points, a centimeter-level of survey accuracy can be achieved.
