CLOSED-SDOT 20-022 City of Seattle Traffic and Revenue Analysis Services

Original Date Posted: July 31, 2020 7:30 am

Due Date:

2:00 p.m., August 27, 2020


Project:  SDOT 20-022 City of Seattle Traffic and Revenue Analysis Services

The City of Seattle, through Seattle Department of Transportation, requests Statements of Qualifications (SOQ) from qualified firms for SDOT 20-022 City of Seattle Traffic and Revenue Analysis Services.

On March 23, 2020, Seattle Department of Transportation (SDOT) closed the West Seattle High-Rise Bridge due to the discovery of rapidly growing cracks. SDOT is now conducting a cost-benefit analysis to inform whether the bridge should be repaired or replaced, and exploring every possible funding option for this program.

SDOT solicits Qualifications from consulting firms or teams that wish to be considered to provide independent traffic and revenues analyses, including an investment-grade traffic and revenue study to explore how much revenue could potentially be raised from tolling for the West Seattle Bridge Program. SDOT has not decided to enact tolling and is conducting this study to better understand the tradeoffs of this potential funding option. This study is also a requirement to pursue other funding options, such as federal TIFIA loans.

A preliminary explanation of activities anticipated to be undertaken by the Consultant include but may not be limited to, existing data compilation and identification of supplemental data needs, traffic and revenue model development (including future network assumptions), economic growth analysis for traffic and revenue studies, traffic and revenue scenarios development, preliminary traffic and revenue analyses for project planning, assessment of appropriate tolling technologies, estimate of tolling system capital and operating costs, traffic and revenue modeling support for the toll rate setting process, equity analyses to identify who would be impacted, who would benefit, and who pays based on social demographics, including income, race, and indigenous tribes, study of income-based tolling models to mitigate cost and impact on historically and currently marginalized communities, traffic and revenue modeling sensitivity testing, preliminary and final Investment-Grade Traffic and Revenue Study (Level III) for a potential TIFIA application, coordinating with SDOT on its congestion pricing efforts with a focus on data analysis and racial equity analysis, and impacts to tolled state routes, including but not limited to SR 99.

This contract is estimated to be up to $2 Million.  This is anticipated to be a multi-year contract, for approximately 1-2 years.  More detail to the schedule will be developed during the course of 2020 as scope direction is confirmed.  Potential phased/future work could be to support the City with alternative modeling after initial study is completed.

An online Pre-Submittal meeting is planned for Thursday, August 6th at 3:00 p.m.  The link to the meeting will be provided on ProcureWare.
