Development of a Geotechnical Asset Management Collection and Rating Program for Missouri Department of Transportation

The Missouri DOT research team, led by Landslide Technology, developed a prototype Geotechnical Asset Management (GAM) program through close collaboration with MoDOT geotechnical engineers and MoDOT’s IT group.  The team adjusted published and commonly accepted categories from state and federal GAM inventory and rating approaches to match conditions specific to Missouri. The GAM program compiles condition and risk assessment for six asset types: engineered embankments, retaining walls, rock slopes, soil slopes, subsidence, and subgrade. Subsidence and subgrade improvements were successfully incorporated into Missouri’s GAM program despite not being previously incorporated into an other DOT’s GAM inventory. The risk assessment rating developed for this project allows DOTs to approximate risk in the absence of site-specific maintenance or accident records.  Data is collected via ESRI’s Survey123 Application before being scraped and processed in MoDOT’s TMS system, where it is added to other department datasets. The application was field-tested on National Highway System (NHS) routes in the Northwest and Northeast Districts in October 2022.
