t o EXHIBIT A CITY OF EVERETT WATER FILTRATION PLANT OPERATIONS BUILDING: STRUCTURAL AND NONSTRUCTURAL SEISMIC RETROFIT PRE-DESIGN, DESIGN, BID PERIOD SERVICES, AND CONSTRUCTION PERIOD SERVICES FOR SEISMIC RETROFIT SCOPE OF WORK April 15, 2015 INTRODUCTION On February 11, 2015,AECOM (Carla Talich, Krystal Li, Travis McIntosh, and Cris Castro) met with Mr. Souheil Nasr to discuss the City of Everett's (City) desire to perform a seismic retrofit of the City's Water Filter Plant(WFP)Operations Building at the Chaplain Reservoir near Monroe, Washington. On the same day, AECOM also conducted a site visit at the facility. The project is primarily funded by the Federal Emergency Management Agency (FEMA),through the State of Washington, Military Department, Hazard Mitigation Grant Program (HMGP). The City and the Washington State Military Department will also contribute funding for the project, as detailed in the HMGP agreement. In the HMPG application, the City described the synopsis of the proposed project as: • The proposed project is only for the Water Filter Plant Operations Building and includes both structural and nonstructural measures for this facility, which is a critical control and system monitoring facility for the entire Everett Water System. The key structural upgrades which mitigate the deficiencies in the pre-cast roof/floor panels and the connections between the panels and the walls are: • Add reinforced topping slabs to the roof/floor pre-cast panel diaphragms, and • Add steel connectors to each panel to improve the connections between the panels and the walls. These two structural measures encompass about 75% of the total project engineering cost estimate. The remaining 25% of the engineering cost estimate covers: • Bracing for columns in enclosure structure for the soda ash bins, • Improved foundation for the Alum tank foundation, • Flex connections for the Alum tank piping, and • Upgrade utility connections at the interface between the building and ground, • Upgrade suspended ceilings in the Operations Room, and • Upgraded anchorage for mixing tanks, storage ranks, desktop equipment, cabinets, electrical panels and HVAC equipment. The scope of work includes preparation of a pre-design evaluation for seismic retrofit of the WFP Operations Building. The evaluation will be documented in a draft technical memorandum to be entitled, "Pre-Design Evaluation for Water Filter Plant Operations C:\Talichleverett-seismic\2_Scope of Work_Operations Bld Seismic Upgrade 04-14-15.docx Page 1 of 8 80
