CLOSED-Moveable Bridge Control – Remote Operation; RFQ #SDOT-17-051

Original Date Posted: May 31, 2017 9:03 am

Due Date: 4 p.m., June 16, 2017


17-051: Moveable Bridge Control – Remote Operation 

The City of Seattle, through Seattle Department of Transportation, requests Statements of Qualifications (SOQ) from qualified Consultants for SDOT 17-051: Moveable Bridge Control – Remote Operation 

This contract is estimated to be up to $375,000 to $425,000.

The Seattle Department of Transportation (SDOT) is requesting Consultant services to provide recommendations for design of a pilot program that will test remote operation of City of Seattle (City) owned movable bridges. SDOT currently operates five movable bridges, three on the Lake Washington Ship Canal and two on the Duwamish River.  All five bridges currently operate from a control tower located at each bridge location.  All five bridges span navigable waterways and operate under a Federal permit managed by the U.S. Coast Guard.  All five bridges currently are operated with a programable logic control system (PLC).

The City anticipates this project to be completed in three phases:

  • Phase 1 – Pilot Program Study and Concept Design (the project solicited for in this RFQ; scope details are provided in Section 5)
  • Phase 2 – Pilot Program Design (a project that may be performed as an amendment to the Phase 1 contract resulting from this RFQ)
  • Phase 3 – Pilot Program Implementation (a project that will be put out to bid for construction services and that may also contain an amendment to the Phase 2 contract for construction phase engineering services)

The primary objectives of the Phase 1 Pilot Program Study are to recommend which City owned bridge should be chosen for a pilot program and to develop a conceptual (30% level) design. Generally, the pilot program should be designed to install communication hardware and control systems that will safely provide remote bridge operation for one City owned bridge to allow passage of vessels when an opening is requested.

The consultant Scope of Work for Phase 1 may include:

  1. Analysis of the complexity of a remote bridge opening, considering impacts to vehicular, pedestrian, bicycle and marine traffic.
  2. Investigation of existing City owned communication systems and the additional communication system components needed to complete the pilot program.
  3. Research of existing remote bridge operation systems currently in use by other transportation agencies to learn about and incorporate successes and challenges from similar projects.
  4. Research and incorporation of U.S. Coast Guard requirements for bridge owners that pursue remote bridge operation.
  5. Recommendation of additional safety systems, sensing systems and other additions to the current bridge operation system to insure an acceptable level of safety, awareness and ability to respond to operational emergencies.
  6. Recommendation of opportunities to incorporate intelligent transportation system (ITS) features within the remote bridge operations system. Design of the ITS features are not part of the scope of work, however, SDOT is aggressively incorporating traffic management features associated with bridge openings. It is anticipated that the work being performed by the Consultant will develop ITS ideas that could be implemented by SDOT to enhance general traffic management.

Delivery of a Pilot Program Study report that captures the results of the other scope items listed above and a conceptual (30% level) design. The conceptual design should result in delivery of Plans, Specifications and Estimate for a complete remote movable bridge operation system.

SDOT has identified all the above tasks as core functions in this scope of work.

A core function is any element of a particular scope of work which SDOT is certain will be performed and completed through all phases of this Contract.  Consultants shall focus on the core functions when developing meaningful and realistic integration of WMBE roles in proposed Inclusion Plans.
