Mobile and Terrestrial Lidar
SCOPE: Support engineering design though the fusion of mobile lidar, subsurface utility engineering (SUE), and conventional survey data.
Located near Abilene, Texas, Dyess AFB serves a critical role in the local economy as well as a front-line role in global military operations. Dyess AFB is home to the 7th Bomb Wing, a premier unit of B-1B Intercontinental Bombers. The unit also features an important C130 Air Mobility Command (317th Airlift Group) with the largest fleet of J-model (modern) C130s in the country.
Infrastructure of all types throughout the United States is aging. Organizations need to increase their inspections, repairs, and maintenance programs to keep this infrastructure viable in a growing economy. In some cases, existing infrastructure doesn’t adequately meet the requirements of today’s equipment. One such example is the Virginia Street overpass along I-65/I-70 in southeast Indianapolis, Indiana.
On February 22nd, 2013, an oversized truck collided with the Virginia Street overpass on I-65/I-70 causing a support beam to split. Due to the risk to the integrity of the structure, INDOT responded swiftly, engaging Continental Mapping to complete a mobile lidar and mapping project for the site. Time was of the essence to provide survey data to INDOT’s engineers so that a design for a repair could be quickly made. This bridge had been closely watched by INDOT for some time given its limited clearances and numerous reported strikes. A local university had even mounted a camera on the bridge to document the dozens of strikes to the bridge both minor and major.
