BACKGROUND & HISTORY:
When working in areas where an arc flash is possible, it is important to evauate what the risk is to know how to best protect those in the area. Arc flash ratings are a measure of the amount of potential danger that someone operating an electrical device faces when in the area. A higher rating means more personnel protective equipment and/or activities are required. The recommended Arc Flash study project is a system-wide evaluation and implementation to reduce the arc flash rating (a safety requirement) at all of the UD’s Wholesale Distribution Access Tariff (WDAT) locations, also known as Electric Substations, and other electrical equipment in its service area, including Water Treatment Plants, Water Reclamation Facilities, well sites, booster stations, and lift stations. This project will evaluate and reduce the arc flash rating to minimize the danger to operations and maintenance staff.
ANALYSIS:
During the Fiscal Year (FY) 2022 budget process, the City Council approved funds for an Arc Flash study in Capital Improvement Project No. 76280.
Request for Proposals (RFP) 22-045RH was advertised pursuant to Corona Municipal Code (CMC) Section 3.08.110, non-public projects formal bidding procedure requirements on Wednesday, April 13, 2022, in the Sentinel Weekly and other digital platforms.
To select a vendor that best serves the City’s service needs, the Purchasing Division conducted the competitive bidding process by means of an RFP, as allowed by CMC Section 3.08.070(G). Staff believes that the RFP conducted for these services is in the City’s best interest because of the importance of the need to have special and a high level of expertise to perform an Arc Flash Study and develop a customized safety program. Specifically, the RFP process allows staff to evaluate potential bidders on additional criteria other than their bid amounts, such as their staffing levels, the firm’s performance history for similar studies, and their safety history.
The evaluation of the proposals recoved was based on four essential criteria: 1. Work Plan/Work Organization; 2. Qualifications of Company and Personnel; 3. Approach to Safety Measures; 4. Cost proposal.
A total of 381 vendors currently registered with Corona and 364 external vendors (not registered with Corona) were notified about RFP 22-045RH. RFP 22-045RH was viewed and downloaded by 28 firms. Four proposals were received by the due date of May 18, 2022, and subsequently reviewed by City Staff.
