Port Gardner Storage Facility Scope of Work 1-06-22 <br /> Activities/Approach: <br /> • Conduct alternatives analysis for the selective demolition of the Kimberly-Clark structures, <br /> process mechanical equipment, electrical, and existing site civil features. <br /> • Review each of the existing site facilities (neutralization basins, chemical storage, aeration <br /> basins, secondary clarifiers, etc.)to determine how the existing facility can be used to serve <br /> design of the PGSF. <br /> • Incorporate the findings of the additional condition assessments conducted under Phase <br /> 210 into the demolition alternatives analysis.The Phase 210 work includes the buried <br /> pipeline investigations and neutralization basin condition inspection. <br /> • Review and verify the demolition recommendations presented in the PGSF Engineering <br /> Report. <br /> • Conduct an alternatives analysis to determine which elements of the existing infrastructure <br /> the City should demolish versus abandoned in place.This determination will include the <br /> following criteria: <br /> o How the infrastructure will serve the final PGSF design and operation. <br /> o Whether the existing infrastructure has the potential to support future use of the site <br /> for nutrient removal processes. <br /> o The scale of demolition to complete in the demolition design package construction, <br /> versus deferred to site design. <br /> o The anticipated cost of demolition versus abandoning in place. <br /> o Anticipated 0&M and health and safety risks associated with abandoning in place <br /> versus demolition. <br /> • Prepare a 20 to 25 page Demolition Alternatives Analysis TM outlining the results of the <br /> demolition alternatives analysis and recommendations for the demolition at the individual <br /> site facilities.This TM will inform discipline leads with the information necessary to develop <br /> the Demolition Basis of Design Report(Phase 230). <br /> Task Assumptions <br /> • This alternatives analysis phase does not include cost estimating. Planning level cost <br /> estimates developed for the alternatives analysis will not conform to AACE guidelines in <br /> terms of detail. AACE is the Association for the Advancement of Cost Estimating which <br /> develops guidelines for the architectural-engineering industry. <br /> • Workshops are assumed to be two hour meetings held on MS Teams. <br /> Everett Responsibilities <br /> • Review the Demolition Alternatives Analysis TM. <br /> Meetings <br /> • Demolition Alternatives Analysis workshop. <br /> Work Products <br /> • Demolition TM, draft and final <br /> 10 <br />
