Scope of Work
Mn/DOT has determined a budget of $250,000 for this project.
Project Overview
Mn/DOT requests proposals to evaluate the bridges and approach roadways, over the Minnesota River for Trunk
Highway 41, Trunk Highway 101, and Trunk Highway 169 to determine what capital improvements would be
necessary to minimize roadway closures and/or add capacity due to flooding events for the existing river
crossings and their approach roadways. Highway 41 and Highway 101 alternatives would primarily be related to
elevating roadway profiles and Highway 169 alternatives would primarily be related to adding capacity with and
without widening existing bridges.
The evaluation will include an alternatives analysis to identify a range of construction approaches. Bridge and
construction alternatives considered will include a hydraulic model development and analysis, high-level preNEPA environmental screening and process overview; appropriate traffic analysis; alternatives identification and
analysis; constructability analysis; total project cost estimate including engineering, right of way, construction and
mitigation; benefit/cost analysis; project schedule and delivery timelines. It is desired to use recently built bridges
and follow existing roadway alignments.
The evaluation will include stakeholder involvement, such as representatives from affected cities and counties; the
U.S. Fish and Wildlife Service, and other permitting/regulatory agencies.
It is desired to have contract work begin in February of 2011 and completed by September of 2011.

Carver County, City of Chanhassen, City of Chaska, Hennepin County, City of Bloomington, Scott
County, City of Shakopee, Jackson Township, and Louisville Township staff. Contractor will
prepare an agenda and a meeting summary for each meeting. Contractor will provide Gantt chart
study schedule updates at each meeting. Assume six progress meetings.
1.1.2 Provide daily instruction and superintendence of work performed by Contractor personnel and sub
consultants.
1.1.3 Perform direct contacts with State functional units and outside agencies to collect information needed
for plans. Contractor will provide copies of communications with State functional units and outside
agencies to State’s Project Manager.
1.2 Stakeholder and Public Involvement
1.2.1 Prepare and facilitate stakeholder meetings including environmental review agencies, permitting
agencies, minority groups, etc as needed. Assume three stakeholder meetings.
1.2.2 Organize and attend open house meetings. Assume two open house meetings.
1.2.2.1
Contractor will prepare and distribute a newsletter before each open house and one at the
study’s completion (for a total of three newsletters) providing an update on study status
and announcing public meetings.
1.2.2.2
Contractor will prepare open house materials, including handouts and presentation
boards.
1.2.2.3
Contractor will prepare open house meeting summaries that include attendance and
comment information.
1.2.3 Provide material to be posted on the study’s web site hosted by Mn/DOT.
1.3 Hydraulic Model Development and Analysis
1.3.1 Develop a 2-dimensional steady state hydraulic model of the alternatives analysis using FESWMS2DH within SMS software. Model extents are approximately 2000 feet upstream of TH 41 to
approximately 5000 feet downstream of TH 101 on the Minnesota.
