MnDOT Geometric Design Institute

The Institute features four three-day workshops that educate Minnesota transportation practitioners on the fundamentals of roadway design. Participants will use design theory, MnDOT standards, and equations to learn the fundamental principles of roadway design. Topics include performance-based practical design, horizontal alignment, vertical alignment, superelevation, quantities, earthwork, cross sections, and more. Participants will engage in hands-on group learning using layouts, scales, highway curves, and triangles.

Each workshop agenda is specialized and will emphasize just two or three topics. Participants may attend one or all workshops.

Workshop Dates, Location, and Details

Both of these workshops will be held at the MnDOT Shoreview Training and Conference Center (1900 County Road I West, Shoreview, MN 55126).

Fundamentals of Roadway Design and Horizontal Alignment

June 7-9, 2022
Day One: 9:00 a.m.–4:00 p.m. Central
Day Two: 8:00 a.m.–4:00 p.m. Central
Day Three: 8:00 a.m.–4:00 p.m. Central

This workshop begins with an overview of road design fundamentals—including an introduction to plan reading and coordinate geometry, followed by an introduction to horizontal alignment and station control, design speeds and controls, and roadway standards. It also reviews how to use the Road Design Manual and accompanying technical memoranda, and how to determine stationing and station equations, sight distance, curvature, and geometrics.

Typical Sections, Cross Sections, Roadside Design, Quantities, and Earthwork

June 21-23, 2022
Day One: 9:00 a.m.–4:00 p.m. Central
Day Two: 8:00 a.m.–4:00 p.m. Central
Day Three: 8:00 a.m.–4:00 p.m. Central

This workshop focuses on roadside design and safety. Each day has interactive activities and case-study-based examples/working problems. Typical and cross sections topics include typical section standards, elements, and development; grades and slopes; developing a typical section using the Road Design Manual and the soils letter; and contours and creating a cross section. Roadside design topics include explaining how to determine and compute clear zone requirements and how to deal with obstructions, barrier design and placement, horizontal clearance to obstruction, ditch sections, and impacts of design speed on clear zone. Quantities and earthwork topics include identifying pay items on a plan set, determining the appropriate units, estimating the amount of each item to be paid for as part of the project, preparing tabulations and final quantities, earthwork and mass balances, shrinkage and expansion factors for a variety of soil types, estimating earthwork quantities, and preparing earthwork tables and summaries.

NOTE: The Institute’s two other workshops—Superelevation, Drainage, and Vertical Alignment and Advanced Horizontal/Vertical Alignment and Intersection Applications—will be offered at a later date.
