Short Circuit Coordination Study and Arc-Flash Analysis Service

The Costa Mesa Sanitary District in Costa Mesa, California is seeking a qualified contractor to perform a short circuit coordination study and arc-flash analysis service. The agency needs to analyze, monitor, and review its existing facilities to produce a comprehensive study report documenting breaker coordination and arc-flash analysis results. This project will solve the problem of outdated system documentation by confirming the accuracy of the station single-line diagram, noting required corrections, and producing an updated single-line diagram. The scope of work requires the contractor to conduct breaker coordination and arc-flash analysis to determine arc-flash levels, and to furnish all necessary field data required by the power system studies. All computer modeling, engineering calculations, and analysis 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. The performance of this work may occur either onsite or offsite. Eligibility is restricted to onshore organizations based in the United States. The agency is currently looking for proposals to determine the budget for this project. Bidders must attend a mandatory pre-proposal meeting on May 28, 2026, and submit all questions regarding the solicitation no later than June 11, 2026.
