Scope of Work – Babcock & Mendenhall Safety Improvements
Task Order No. DTN22-002
6/7/22
As a follow-up to the completed Downtown Transportation Study, Sanderson Stewart is pleased to provide
this scope of work for Babcock & Mendenhall Safety Improvements. It will include data collection, traffic
analysis, conceptual design and reporting. A detailed list of assumptions and scope of services for the project
are outlined below.
Scope of Work:
Phase 1 – Project Management and Coordination
This phase of the project will include project initiation and planning tasks, including scoping, contract
preparation, and kick-off meetings with the Downtown Bozeman Partnership, City of Bozeman and MDT.
Other project management tasks include the following:
· Coordination with Client and project team
· Coordination with City of Bozeman and MDT
· Research and review of previous related studies (including the DBIP and the Bozeman Transportation
Master Plan) and MDT’s Comments on the Downtown Bozeman Improvement Plan and the
Downtown Transportation Study.
· Correspondence, phone calls and meetings throughout the duration of the project
· Weekly project update emails
· Monthly invoicing of project fees/expenses
· Internal (project team) coordination and quality control reviews of analysis and deliverables
Phase 2 – Data Collection
Sanderson Stewart will begin with traffic volume data collection using Miovision video data collectors. This
effort will consist of 24-hour turning movement counts at the following 6 intersections:
· Babcock Street & Black Avenue
· Babcock Street & Tracy Avenue
· Main Street & Black Avenue
· Main Street & Tracy Avenue
· Mendenhall Street & Black Avenue
· Mendenhall Street & Tracy Avenue
Existing annual average daily traffic (AADT) volume data from MDT will also be reviewed and summarized
for this analysis. Vehicle speeds will also be recorded along Babcock Street and Mendenhall Street corridors.
Other tasks include:
· Set up, relocation and retrieval of Miovision Scout video data collectors and speed radars at the
locations identified above
DocuSign Envelope ID: E00FA1D5-174F-43B0-B05F-B34D6226E6CE
· Data processing through Miovision, including bicycle and pedestrian counts and vehicle classification
(processing of 24 hours/intersection)
· Factor count data based on historic area traffic counts and current construction closures
· Format count data and develop study area maps to illustrate existing traffic control and existing
volumes
· Data processing of corridor speeds for a 7-day duration
· Sign inventory of Babcock and Mendenhall corridors
Phase 3 – Evaluation of Intersection Improvements
The traffic analysis tasks will begin with an evaluation of intersection capacity conditions. Sanderson Stewart
will prepare intersection models for the project intersections. The models will initially be created for existing
conditions so that a direct comparison of analysis results can be provided for existing conditions and
recommended improvements. The following tasks will be completed in this phase:
· Set up intersection models in Synchro to conduct capacity analysis for existing conditions (traffic
volumes, traffic control and lane configurations)
· Analysis of bike and pedestrian performance measures for existing conditions
· Prepare summary tables for review of analysis results
· Request crash data from MDT for study area
· Review and summarize crash data, calculate metrics and prepare summary figures
· Perform traffic signal warrant analysis
· Evaluate pedestrian crossing safety improvements
· Develop study area maps that show future traffic volume scenarios
Phase 4 – Evaluation of Corridor Improvements
The recommended improvements from the DBIP and Downtown Transportation Study will be evaluated using
the same methodology used for intersection analysis. The recommended improvements will be added to the
models and they will be analyzed for existing and future traffic volumes. The following tasks will be included:
· Set up corridor models to conduct capacity analysis with recommended improvements and existing
traffic volumes
· Use corridor models to conduct capacity analysis for recommended improvements and future traffic
volumes
· Analysis of bike and pedestrian performance measures for recommended improvements with existing
and future volumes
· Evaluation of corridor vehicle speeds
· Review of corridor sign clusters
· Prepare summary tables for review of analysis results
· High-level evaluation of potential conversion of corridors into two-way traffic in narrative format
· High-level evaluation of potentially reversing direction of one-way traffic on project corridors in
narrative format
Phase 5 – Concept Designs
The design concepts developed under the Downtown Transportation Study will be revisited to assess if any
revisions to the original improvement recommendations may be necessary based on the results of the analysis
effort in Phase 3 and Phase 4. Other improvements may be identified during the analysis phase and will be
DocuSign Envelope ID: E00FA1D5-174F-43B0-B05F-B34D6226E6CE
added to the design concepts as needed. Up to one alternative concept design will be considered for each
corridor and intersection to address any areas where the analysis results do not support the improvements
recommended in the DBIP.
Phase 6 – Engineer’s Opinion of Probable Cost
Opinions of probable construction cost will be developed for each of the design recommendations and
alternatives developed. They will be broken down by individual project/improvement.
Phase 7 – Summary Report
The preceding analysis and design concepts will be presented in a summary report. This report will present the
following project elements:
· Background information and research
· Summary of all analysis completed for existing and future traffic volumes and with recommended
improvements
· Summary of recommended improvements
· Recommendations for any amendments to the Bozeman Transportation Master Plan or the DBIP (as
required)
· Concept design illustrations for recommended improvements
· Planning-level opinions of probable construction cost for recommended improvements and
alternatives
· Summary of public participation process, including comments matrix (appendices)
· Next steps and potential funding opportunities
A draft report will be submitted for review to the Downtown Partnership, City of Bozeman and MDT. A final
report will be prepared after all review comments are received and addressed.
Exclusions:
The following items are not expected to be needed for this project and are therefore specifically excluded from
this scope of work:
· Full topographic and boundary survey of the proposed projects
· Analysis of additional major improvements not included in this scope, such as conversion of Babcock
or Mendenhall to two-way operation. These elements will be addressed in narrative format only.
· Regional travel demand modeling (using MDT model)
· Design of any roadway or intersection improvements beyond concept-level as described above
· Presentation of findings beyond the review meetings
If needed, these items will be added as a separate task order or contract amendment.
