The City of Portland Water Bureau is seeking proposals from individuals, firms, teams or consultants, hereafter called "Proposer(s)," with demonstrated experience in the seismic assessment of bridges. The successful Proposer will perform a seismic assessment of the Larson's Bridge and the Bowman's Bridge. There are two (2) key milestones for this Project. The first is the production of a digital model utilizing one of the current industry standard structural modeling software packages. The second is a report documenting the findings of their assessment and providing recommended improvements for the bridges if they are not able to withstand the required loadings. The seismic assessment will consider both the Moment Magnitude 9.0 CSZ Event and a Maximum Considered Event (2,475 period event). The City of Portland (City) Water Bureau (PWB or Portland Water Bureau) strives to provide high quality water to enhance the public health and safety and contribute to the economic viability and livability of the Portland metropolitan region. We are a recognized leader among water service agencies across the country. The seismic assessment of the Larson's and Bowman's Bridges in the Bull Run Watershed aligns with the PWB's mission statement of providing reliable water service to customers as well as being responsible stewards of the public's water infrastructure and natural resources.
