Short Circuit Coordination Study and Arc-Flash Analysis Service

The Costa Mesa Sanitary District in Costa Mesa, California, requires a comprehensive short circuit coordination study and arc-flash analysis service for its existing facilities. The agency is seeking to identify arc-flash hazard levels, verify the accuracy of the station single-line diagram, and obtain an updated and corrected single-line diagram. This initiative will solve the problem of undocumented electrical hazards and outdated system diagrams, resulting in a final study report that documents all breaker coordination and arc-flash analysis results. The scope of work covers conducting analysis, monitoring, and reviewing existing facilities to perform the necessary short-circuit, protective device coordination, and arc-flash hazard analysis studies. The selected contractor must perform computer modeling, engineering calculations, and analysis, as well as furnish all field data required by the power system studies. All calculations, modeling, and studies must be conducted under the supervision and approval of a registered professional engineer who is experienced in performing and interpreting power system studies, electrical calculations, and electrical engineering studies. Eligibility is restricted to onshore organizations based in the United States. The agency allows the performance of the work to be conducted either onsite or offsite. The agency has not disclosed a specific budget and is currently looking for proposals to determine the cost of the project. The agency has established key dates for this procurement process. A mandatory pre-proposal meeting will take place on May 28, 2026. Bidders must submit all questions regarding the opportunity no later than June 11, 2026.
