Abstract: Following devastation caused by Hurricane Helene throughout the Western North Carolina region in September 2024, North Carolina Department of Transportation (NCDOT) reached out to the engineering community for the crucial rebuilding process under an emergency condition. As part of the RK & K design team for the reconstruction of Interstate 40 (I-40), Schnabel developed an expedited and comprehensive investigation program for the first 5-miles in North Carolina. Interstate 40 experience numerous failures along the five-mile corridor which is adjacent to the Pigeon River. In order develop repair concepts and ultimately design the permanent repairs, an exploration program was established that included desktop review of historic geotechnical data, rock probes by air track drilling, rock probes by soil nail drilling, rock core sampling with standard coring methods, and geophysical study using MASW methods. A suite of lab testing was performed to characterize engineering properties of the subsurface soils and rock.

A large amount of data was gathered, and the need was recognized to keep the records in an organized fashion to streamline data review. An internally developed database system (MORTAR) that integrates different applications and services was used. To allow a seamless and unified project delivery. Using MORTAR, tools data mapping and integration is possible, facilitating a more informed design process.

This presentation will discuss methods of exploration, data organization, and descriptions of the geotechnical assessments for design and construction
