Amendment 1 PSA with Brown and Caldwell for Port Gardner Storage Facility Project Exhibit A Scope of Work 31 − Complete an arc flash study, fault current analysis, and breaker coordination for PGSF, including Lift Station 46. This work includes modeling the electrical distribution system for each area using electrical power system analysis and performing an initial arc flash study. The arc flash study will be initiated during intermediate design and confirm the power feed and distribution presented in preliminary design. This work includes coordination with Snohomish PUD (SnoPUD), development of an SKM Systems Analysis model, and confirmation of breaker settings. A final up arc flash study will be completed following construction to confirm the facility as-built conditions (see Phase 670 Task 800). • Task X16 – Division 00/01 Specifications − Modify and add to the demolition package Division 00 and 01 specifications to apply to the PGSF package. Additions include operation and maintenance, equipment storage, start-up and testing specifications, and forms and procedures related to electrical and equipment. − Conduct 2 meetings with City to coordinate requirements associated with bidding and contracting procedures and City’s third-party construction management firm. • Tasks X17 through X19 – General − Legends, abbreviations, index of drawings, cover sheet, location and vicinity map will start with the demolition package versions and be updated for PGSF package. − Design criteria, hydraulic profiles, and process schematics for combined sewer and stormwater. Tasks X21 through X95 all focus on discrete facilities of the PGSF and include tasks for each discipline involved with the exception of architectural that is covered in Task 411. The design for each facility will be advanced from what is defined in the BODR and Preliminary design. • Tasks X21 through X24 – Debris Removal • Tasks X31 through X34 – Primary Storage • Tasks X41 through X44 – Secondary Storage/SWEQ • Tasks X51 through X54 – Effluent Pump Station − Conduct transient hydraulic analysis and determine mitigation measures. • Tasks X61 through X64 – LS46 − Conduct transient hydraulic analysis and determine mitigation measures. • Tasks X71 through X74 – Stormwater Diversion/Treatment • Tasks X82 through X85 – OMES • Tasks X91 through X95 – Old Chemical Building Assumptions • City will continue to accept a hybrid CAD standard that includes applicable City standards and BC standards to accommodate the use of BIM tools and 3D design. • Workshops are assumed to be two-hour meetings held virtually via MS Teams. Everett Responsibilities • Participate in site visit and workshops. • Assist BC with the execution of all bidding activities, including management of bid advertisement, distribution of bid documents and bid addenda to potential bidders and plan centers, management of plan holders list, prepare agenda and notes and conduct pre-bid meeting and management of bidder questions to convey to BC for including in Bid Addenda.
