possibility is that the second bridge may have to be built at a higher deck surface elevation at the crossing, which again could interfere with existing bridge. Because we now have questions about the feasibility of constructing a second parallel bridge, staff is recommending that this assumption be studied prior to entering a contract to begin design, environmental documents, and permitting. If it is determined that a second bridge is feasible, subsequent work will be based upon this study. If it is determined that a second bridge is not feasible, the City will need to consider the schedule for complete bridge replacement. The question will be whether the bridge will be replaced as a routine project, or will the bridge be replaced only when it is critical due to the existing bridge no longer being able to stay in service? It should be noted that the existing bridge is sound and can service all crossings for the foreseeable future. Note that if it is feasible to construct a second parallel bridge while the existing bridge is in service, the crossing of the ADLL will not be affected while the new bridge is being built. Similarly the new bridge would be designed to serve all traffic so when the existing bridge is replaced at some point in the future the crossing would remain in service. A Request for Qualifications (RFQ) was advertised in January 2016 seeking proposals from consulting firms interested in assisting the City with the project as budgeted in the CIP, which included design and permitting. Four firms responded with Statements of Qualifications. Staff interviewed all four firms and chose BCA as the most qualified to perform the required scope of work. Development of the detailed scope of work and fee negotiations with BCA began thereafter. It was at that time that the effects of the Winter 2015/16 became apparent. The agreement staff is recommending that City Council approve today is only for the feasibility study. If the study determines a second parallel bridge is feasible, staff will present another agreement to City Council for approval to advance the project as outlined in the CIP budget, utilizing the same consultant selected through this RFQ process.
