City of Everett,Washington I Reservoir 3 Structural Improvements PDB Project Progressive Design-Build Contract I Exhibit B.Owner's Project Criteria will include measures to improve the seismic resiliency of the reservoir until future improvements or replacement of the reservoir are completed. Phase 1 will include additional seismic study, development of alternatives for potential seismic upgrades for review with the City, and potentially design of seismic improvements. The City will make a determination on inclusion of seismic upgrades in the Project detailed design and construction scope, depending on the results of seismic assessment and seismic upgrade options and costs. The Design-Builder is expected to review Reference Documents, conduct field investigations, and communicate with the City to develop and confirm recommendations for structural and other improvements to address the problems and needs identified by the City to-date or by the Design-Builder during their investigations. The following sections outline and describe the Phase 1 tasks to be completed by the Design-Builder in order to assess and develop solutions for the structural needs and other needs identified in the Project scope. 3 Codes, Standards, and Guidelines Improvements shall be designed based on the most current applicable codes, and most current applicable industry standards and guidelines as referenced in this Exhibit, unless otherwise indicated. Note that seismic improvements are not expected to bring the Reservoir 3 cover up to current seismic codes; the City has established a preliminary seismic performance target that is lower than current seismic codes (see Table 1), and which may be modified based on the seismic improvements that are recommended by the Design-Builder. Where codes and design criteria are subject to interpretation, Design-Builder shall select design parameters and criteria that result in a more robust and long-lasting facility or structure. Where codes and standards conflict, the code or standard giving the most conservative design shall govern. (Note that seismic improvements are excluded from this requirement). Societies, industry groups, organizations, institutes, and agencies issuing these codes, standards, and guidelines include, but are not limited to, the following: 1. American Concrete Institute (ACI) 2. American Institute of Steel Construction (AISC) 3. American National Standards Institute (ANSI) 4. American Public Works Association (APWA) 5. American Society of Civil Engineers (ASCE) 6. American Society of Mechanical Engineers (ASME) Page 2 of 12
