Task 7.1 As-built Analysis <br /> The CONSULTANT will perform seismic analysis of the existing structure to determine <br /> potential seismic vulnerabilities. Seismic analyses will include non-linear static 'pushover' <br /> and response spectrum dynamic analysis, as well as section capacity determination on parts <br /> and/or the whole structures using the bridge seismic retrofit design parameters established <br /> in the General Assumptions listed in the SCOPE. <br /> Task 7.2 Post-retrofit Analysis <br /> The CONSULTANT will perform seismic analysis of the existing structures incorporating <br /> proposed schematic retrofits developed for the CDR. The schematic retrofits will be <br /> analyzed and preliminarily sized for the seismic demands. Seismic analyses will include non- <br /> linear static 'pushover' and response spectrum dynamic analysis, as well as section capacity <br /> determination on parts and/or the whole structures using the bridge seismic retrofit design <br /> parameters established in the General Assumptions listed in the SCOPE. <br /> Assumptions: <br /> • Post-retrofit analysis will be performed incorporating the proposed schematic <br /> retrofits developed for the Draft CDR. <br /> Task 7.3 Constructability, Cost Estimate & Construction <br /> Schedule <br /> Constructability:The Consultant will review the preliminary retrofit options for practical and <br /> cost-effective construction. A memo will address practicality and risks associated with <br /> construction. <br /> Cost Estimate:The CONSULTANT will prepare a construction cost estimate (engineer's <br /> estimate) based on the 10% Design Plans included in the CDR. Cost estimate will be quantity <br /> based using conceptual level unit pricing referenced from WSDOT or other sources as <br /> necessary. Cost estimate will include appropriate values for escalation and an estimation of <br /> right-of-way costs (if applicable). <br /> Schedule:The CONSULTANT will prepare a construction schedule based on the 10% Design <br /> Plans included in the CDR. Construction schedule will be developed in MS Project software. <br /> Maple Heights Bridge Seismic Retrofit 20 <br />
