Seismic Analysis

The Washington State Department of Transportation (WSDOT) solicits interest from consulting firms who wish to be considered for an On-Call Agreement to assist WSDOT Bridge and Structures office in the analytical investigation and feasibility of a friction-pendulum base isolation system for the Aurora Avenue Bridge on SR 99 in Seattle.

Project Description
WSDOT intends to set up an agreement with a bridge design consultant, familiar with the structural modeling and analysis of friction-pendulum base isolation and who has prior experience working with friction-pendulum base isolation systems. The purpose is to obtain professional engineering services from the selected firm to utilize the existing analytical structure model and perform a non-linear analysis incorporating synthetic earthquake time-histories to determine the effectiveness of a friction-pendulum base-isolation system, to protect the existing structure from damage in a major earthquake.

The selected firm is expected to include on their team a Geotechnical company familiar with the bridge site to develop site-specific time histories representing the Cascadia subduction and Seattle Fault earthquake hazards.

The selected firm is expected to work closely with WSDOT design staff and friction-pendulum base isolation system manufacturers and other design companies to develop a comprehensive report on the ability of friction-pendulum base-isolation bearings to protect this major bridge from damage in a seismic event.

Evaluation and Selection
The selection of a consultant for this project will be made from the list of qualified consultants responding to this Request For Qualifications (RFQ.) All firms responding will be evaluated, scored and ranked. The top firm will be selected from the scored and ranked roster and provided with a series of tasks, within the limits of the agreement. Selection from the roster will be by either an interview process or selection of the top ranked firm from the roster.

The amount to be set up for the agreement is $300,000. The firm selected from the roster will be contracted by WSDOT for a two-year term. Individual tasks will be negotiated as stand-alone assignment and the agreement terminated when the agreement budget is exhausted or the time frame has expired.

Consultants will be evaluated and ranked based on the following criteria areas:

  • Key Personnel (15 Points)
  • Experience involving analysis of major bridge seismic retrofits using friction-pendulum bearings. (40 Points)
  • Demonstrated ability to meet schedules (10 Points)
