Specifications include, but are not limited to: 1) Create and calibrate a snowplow routing model that can accurately represent SDDOT’s current winter maintenance operation and reliably evaluate alternative routing strategies. 2) Use the calibrated routing model to identify more efficient and effective winter maintenance strategies. Tasks: 1) Meet with the project’s technical panel to review the project scope and work plan. 2) Interview select SDDOT staff to identify winter maintenance concerns, priorities, and performance goals. 3) Compile information related to SDDOT’s maintenance policies and practices, resource availability and utilization, and measured performance needed to model SDDOT’s current winter maintenance operation. 4) Create and calibrate a routing model that accurately portrays SDDOT’s current operation, resource utilization, and achieved performance level. 5) Prepare and present for approval of the project’s technical panel a technical memorandum summarizing the results of tasks 1-4.
