Unmanned Aerial Vehicles (UAVs) are having positive effect on the design and maintenance of public facilities and infrastructure. UAVs (drones) combined with 3-D technology are being used to upgrade surveying and construction drawing development. The City of Peculiar, Missouri, used drone and 3-D photography to enhance the surveying for the new 28,000-foot sewer interceptor design and installation. Costs were lowered approximately 30% from traditional surveying techniques.

Learning Objectives: At the conclusion of this session, you will be better able to:

Benefit from the lessons-learned by Peculiar’s sewer interceptor upgrade project.
Identify when to use UAVs and 3-D photography to provide topographic survey data and pre-construction imagery.
Plan for the use of UAVs and 3-D photography to orthorectify outdoor assets for collection systems and treatment plants.
