Report
Summary
The purpose of this project is to assist with projects at the facility to improve the functionality, efficiency, and maintenance of the electrical, instrumentation and control systems. The City has developed electrical, instrumentation and control standards for the entire Water Services Department which are used to provide consistency throughout the department. One of the objectives will be to assist the City in ensuring adherence to these standards on all projects during the design, construction, calibration, testing and commissioning of the electrical, instrumentation and control systems. They will provide operations and maintenance support when City staff are replacing existing equipment or installing new equipment. Additionally, they will provide Arc Flash Hazard Analysis services by providing support to update and maintain Arc Flash modeling and documentation for compliance with National Fire Protection Agency (NFPA) requirements.
The Engineering consultants services include, but are not limited to:
Design support services consisting of technical support and consultations relative to installation techniques and procedures, ensuring adherence to the City standards, and ensuring adherence to applicable electrical codes. They will attend design meetings and demonstrations, support research of existing conditions, conduct design reviews, and support facility-wide understanding of the Water Services Department's standards for electrical, instrumentation and control systems. In addition, they may be required to support City staff in updating and maintaining the Water Services Department's standards as necessary.
Construction support services consist of reviewing equipment submittals, conducting reviews on the equipment installation, providing field observations reports, participating in factory testing, reviewing the completeness of required equipment testing documentation and witnessing the instrumentation calibrations and loop checks.
Commissioning support services consist of providing assistance on computer control strategy checkout, tuning of control loops, and performing loop tests, troubleshooting for the computer control system programmers, maintaining designated instruments through final acceptance, educating the plant staff on the systems, supporting the maintenance staff on developing maintenance procedures for designated equipment and reviewing the accuracy of the as-built documentation for electrical drawings and the process and instrumentation diagrams.
They will be required to provide Arc Flash Hazardous Testing services using a professional electrical engineer. The Arc Flash Hazardous Testing will include as-building existing single line diagrams, conducting load calculations for motor control centers, switchgear and power panels, and having the knowledge to conduct a power system study. The selected firm will be required to access energized equipment and provide all arc flash safety personal protective gear that meets the requirements of NFPA.
