Description

The Brent Spence Bridge (BSB) Corridor Project, commissioned by the Ohio Department of Transportation (ODOT) and the Kentucky Transportation Cabinet (KYTC), aims to enhance the Interstate-71/Interstate-75 (I-71/75) corridor by widening the highway and constructing a companion bridge over the Ohio River. A critical component of this three-phase Design-Build project involves meeting environmental commitments by diverting all interstate runoff from the BSB corridor's combined sewer system into a newly constructed stormwater trunkline. This presentation will focus on the combined sewer modeling conducted in Autodesk InfoWorks ICM and the stormwater modeling using Autodesk Storm and Sanitary Analysis (SSA). Key topics include the project's initial objectives, stakeholder challenges, scope expansion, model calibration with incomplete data, and the complexities of adhering to a Design-Build schedule, as further described in the learning objectives below. Learning Objectives: Integrate model development timelines and goals within a progressive Design-Build schedule. Implement calibration techniques to address challenges posed by incomplete or limited data and establish criteria of an acceptable level of model calibration for the combined sewer detailed model in ICM. Describe the coordination of ICM and SSA models to support analysis and guide solution design. Develop stakeholder-aligned solutions to mitigate flooding issues within the BSB Corridor Project.
