Pape-Dawson Consulting Engineers, LLC was deemed most qualified based on their Statement of Qualifications submission for RFQ No. 2021-0377-XR Category 2. Pape-Dawson Consulting Engineers, LLC also has successful experience with traffic control designs and intersection improvement designs at major diamond intersections with work in Fort Worth and Bexar County.
The benefit of this project includes improving wrong-way driving countermeasures at all diamond intersections, standardizing signs and pavement markings for all diamond intersections, and improving pedestrian facilities.
Not approving the expenditure would result in the loss of a federally funded construction project and continued non-standardized diamond intersections resulting in more crashes and potential wrong-way driving behavior.
