WPCF Electrical Upgrades Scope of Services 4 of 5  City to review Condition Assessment TM and provide a single set of consolidated comments.  Power Quality data gathering will be conducted by the City with City equipment at an interconnection location determined by the engineer for 1 month. Data output shall be in MS Excel or other comma delimited form easily read by MS Excel. This data shall be transmitted to BC for analysis and use in the Power Quality TM.  SNOPUD Coordination – After review of the site single line diagrams, automatic transfer at low voltage side of the system is not feasible. As such, automatic transfer would need to be accomplished at medium voltage on the SNOPUD side of the equipment. This task includes 60 hours for coordination meetings with SNOPUD and a summary report of findings. The findings are to include:  Condition of, and/or schedule of replacement of the medium voltage feeder cables to the plant (supposition based upon Everett personnel interviews).  Possibility of automatic transfer equipment at MV side of the system.  Acquiring digital maps representing all the MV equipment and underground service feeds for the plant. Task 2-2 Preliminary Design (30%) Objective Provide design documents representing the replacement of the low voltage electrical distribution equipment. Activities Activities for this task include:  Development of design criteria with the City (Basis of Design, electrical only) including equipment manufacturer selection  Demolition Single-line diagrams  New Single Line diagrams  Engineer's estimate of equipment costs (Manufacturer Quotations)  Design review workshop – 1 hour (virtual) design review, 2 engineers Deliverables Deliverables for this task include the following:  30% design documents – See Attachment A, Drawing List for detail.  Design Specifications – See Attachment B, Specification List – draft specifications will be a portion of a later deliverable. Assumptions Assumptions for this task include the following:  City review comments will be provided as a single set of consolidated comments.  No building modifications will be required.  No environmental permitting or land use activities are included in this scope of work.  No modifications to the site standby generator systems are included in this scope of work.  No modifications to the existing control systems are included in this scope of work. Existing controls relating to site MCCs and Switchboards are assumed to be de- terminated during demolition activities and re-terminated at similar locations (physical wire lengths sufficient) in new equipment during construction.
