17060 P a g e | 11 Proposal for Storm Drain Pump Station Improvements Projects BRADFORD PUMP STATION the consultant team. Any pertinent supporting calculations will be included with the submittals. All drawings and specifications will be prepared in conformance with City CADD standards. The electrical integration and controls engineering subconsultant will provide electrical, instrumentation and controls design services. Listed below are the electrical, instrumentation and controls design assumptions. 1. Existing service at the site will be replaced with a new service suitable for the new pump loads. Power feed assumed to be 3 phase, 480V; new pump sizes generally match pump sizes shown on the 30% plans included with Task 3.2 Preliminary Engineering Report. 2. Backgrounds of the new pump station and site plans will be provided to the electrical integration and controls engineering subconsultant in .DWG format for use as backgrounds. 3. The electrical integration and controls engineering subconsultant’s Standard Legend Sheet and Standard Details will be used. 4. Stormwater pump station wetwell assumed Class 1, Div 1 per NFPA 820. All new electrical distribution and motor control equipment to be located outside or in otherwise unclassified areas with suitable conduit sealing or barriers as required by the NEC. Addition of ventilation to declassify existing areas subject to classification per NFPA 820 is not included. 5. New site and facility exterior lighting will be provided for maintenance, site security, and life safety. Limited lighting will also be provided within the wetwell for inspection purposes. Lighting will be based on energy efficient fixtures and illumination levels meeting Title 24 efficiency criteria. However, formal Title 24 compliance including energy calculations and completion of forms will not be required for obtaining approval from the City Building Department or for pulling permits 6. Provide new stationary standby engine generator sized for full pumping capacity at the facility. 7. Normal pump control assumed based on level transmitter (4-20mA) and local programmable automation controller (PAC). Pump controls to include independent float and relay-based backup. 8. Incorporate remote monitoring and controls meeting current City standard SCADA and telemetry platforms. Control component details, communication medium, and any City standardized equipment and software shall be provided to the electrical integration and controls engineering subconsultant for incorporation into the design. Work shall include development of pump station control strategies, design drawings and specifications for SCADA system hardware and software, control panel and instrumentation specifications, and specification requirements for a System Integrator subcontractor to implement the SCADA system integration under the Project General Contractor. All specified SCADA system hardware, software, and programming standards shall conform to City standards where such standards (formal or de facto) exist. 9. P&IDs for the new stormwater pump station will not be required. 10. Equipment identification will be developed to ensure unique equipment identification within the facility following general ISA standards. City has no established equipment tagging standard. 11. Specifications assumed based on the electrical integration and controls engineering subconsultant’s standard electrical specification sections. ATTY/AGR.2021.257/Wood Rodgers, Inc.
