Capturing Culverts – Using mobile GIS technology to capture and track drainage assets.

Date and Time: Friday: 1:00 PM - 2:30 PM
Location: NAS 120

PRESENTATION DESCRIPTION

Drainage, specifically culverts, is a key asset when discussing transportation infrastructure. A lack of drainage, or failed drainage structures can often lead to massive damage or a total roadway loss. Even with this high importance of culverts, few agencies have a comprehensive GIS network for these assets. This is especially true for culverts less than 48 inches in diameter. To address this issue, the Tennessee Department of Transportation (TDOT) partnered with Esri to develop a Culvert Condition Assessment Program (CCAP) with the goal of geolocating culverts that cross state routes or interstates. This program is also devised to collect a condition assessment of the different characteristics of the culvert system.

Using Esri software allows TDOT to keep a history of the culvert in terms of condition from installation to replacement. This will allow TDOT to build condition curves for types of culvert materials within specific areas across Tennessee.

This culvert project also spawned a smaller project to geolocate and assess the condition of underdrains across all interstates and state routes.

This presentation will discuss the challenges TDOT and Esri overcame, and some valuable lessons learned from this project. This presentation will also focus on the data visualization tools to communicate the information collected by these programs to all levels of TDOT. The visualizations that will be presented are very important to our field maintenance supervisors and enables them to prioritize repairs and replacements.
