CA SNE ENGINEERING, INC. Electrical and Technology Consultants September 13, 2016 City of Everett Public Works Department 3200 Cedar Street Everett, WA Attention: Rich Hefti, Project Manager Subject: Everett Three Lakes Pressure Sustaining Valve Electrical Design Scope and Fee Estimate Rich, in response to the City's request to provide electrical power and controls for a new Pressure Sustaining Valve installation at the site of the existing Ball Valve Type PRV, we have developed this scope and fee estimate. We understand that the existing PRV has a three phase 230 VAC electric service and telemetry communications. The City requests we design standby power for this facility with an Automatic Transfer Switch and Standby diesel engine generator in a sound attenuated enclosure. The City wants to provide power and controls to the new 36" PSV vault with lighting, receptacles, a sump pump, exhaust fan and heat. We will monitor pipeline pressure above and below the PSV and will provide a remote operator interface in the PSV Vault. We will provide conduit and wiring back to the building for power, controls and telemetry monitoring. A future Flow meter vault will be provided for either an insertion type flow meter or a strap on ultrasonic flow meter. This future vault will require a sump pump and lighting, but no heat or exhaust fan. We understand that the City requests that the project design be completed by January 2017 and bid thereafter. The construction is expected to take into early 2018. A 60% submittal will be scheduled for September or early October. To accomplish this we anticipate the following design tasks: 1. A site visit to check the installation with the original design drawings and mark changes that have been made by the City in construction of the block building. 2. Provide a one line diagram for the existing service with the addition of the ATS and standby generator and power extensions to the new PSV Vault and the future Flow Meter Vault. Provide a demand calculation to verify that all new equipment will fit within the existing service. 3. Generator calculations to determine that the station loads will start and run. 4. A plan and elevation for the new PSV vault with all equipment and wiring shown. 5. Control wiring for the PSV, open and close solenoids, valve position indication, upstream and downstream pressure transmitters and the future flow meter. 6. Telemetry Control Panel additions shown in elevation. We will provide the following construction services tasks: 7. Contractor questions during bidding. 8. Submittal reviews. 9. Response to contractor questions during construction 128
