review, analyze and summarize the data received. The Engineer will review the following data and information. 1) Previous studies and reports prepared by the Engineer and others 2) Record drawings of process facilities receiving power from the eight onsite transformers 3) Recent electrical utility records 4) Operating and maintenance financial and technical data 3. Survey Facilities and Review Record Drawings a. Engineer will perform an evaluation of the Wastewater Treatment Plant's electrical system by conducting an extensive site survey to identify and confirm the electrical loads and generator sources connected to the electrical distribution equipment associated with each of the eight utility transformers. This survey will include a review of electrical generator systems and an equipment survey. b. Engineer will review available record documents and information related to Owner's electrical distribution system as well as meet with the Owner's staff to discuss needs and questions associated with each of the eight utility transformers and the areas they serve. Documents and information that will be reviewed include: power one -line diagrams, equipment shop drawings, arc flash documents, and electric utility records. The information obtained from the site survey and the record drawing review will be assimilated into an overall plant power single -line diagram. In addition, electrical load studies will be developed for each of the utility transformer distribution systems. Each load study will identity active and inactive loads, with the appropriate load diversity associated with the equipment. In the course of the site investigation electrical safety and SCADA Network switch locations within electrical cabinets will be identified, noted, and recommendations made for relocation of each. Engineer will summarize the above information in the Electrical Evaluation Report. 4. Standby Power Assessment and Recommedations a. Engineer will perform an evaluation of the Wastewater Treatment Plant electrical generator systems based on the Task 3 site investigation and equipment survey. The assessment will summarize the plant's current standby power capabilities, and will address the impacts on process for areas lacking backup power. Critical equipment; pumps, clarifiers, aeration, disinfection, digesters, dewatering, etc., will be identified and evaluated for connection to backup power systems. The assessment will also include review of existing utility records and evaluation of peak shaving using standby power generators. Generator backup needs will be identified for two scenarios: normal flow up to 48 MGD and peak flow up to 77 MGD. 5. Electrical System Assessment and Recommedations a. Engineer will utilize information gathered from information requests and during site visits and workshops to perform an assessment of the electrical system, standby power Page 2 (Exhibit A — Engineer's Services) EJCDC E-500 Agreement Between Owner and Engineer for Professional Services Copyright © 2008 National Society of Professional Engineers for EJCDC.
