Description

Under a master task order agreement, various Phase I preliminary engineering and environmental studies were performed at various locations throughout IDOT’s District 1.

The task order included assisting District 1 with management and implementation of an ADA Transition Plan. Designs included affected curb and gutter, dimensioning, and labeling of sheets, and determining quantities per curb ramp. Excel sheets were developed and used to aide in the design and QA/QC procedure of the ramps. Non-ADA compliant ramps were then designed using IDOT ADA standards. In scenarios where ADA compliance could not be met, ramps were designed to the maximum extent practicable and IDOT was provided with the necessary documentation.
