Audit Services

The County of Orange's Internal Audit Department is seeking proposals for comprehensive Audit Services through a Request for Proposal (RFP) due on July 8, 2025. The procurement will cover multiple audit types including performance, compliance, information technology, internal control, forensic, and operational audits across the County's 22 departments. Qualified firms must demonstrate expertise in conducting professional audits following Government Auditing Standards and Global Internal Audit Standards. The evaluation methodology will allocate 430 points for firm background and qualifications, 425 points for work plan and project approach, and 45 points for contract compliance, with an additional 100 points assigned to pricing proposals. The contract will be structured as a Regional Cooperative Agreement (RCA) enabling County departments and California local and state governmental entities to issue subordinate contracts using established provisions and pricing. Hourly rates will be established for various staffing classifications including Partner, Senior Manager, Audit Manager, Experienced/Senior Auditors, and Administrative Assistants. Respondents must meet minimum qualifications outlined in the RFP and demonstrate capability to provide the specified audit services.

The RFP includes specific preferences and potential scoring advantages for Local Small Businesses (OCLSB) and Disabled Veteran Business Enterprises (DVBE), creating opportunities for these designated business types. The proposed contract will have a three-year term with potential renewal for two additional years, subject to mutual written agreement and County Board of Supervisors' approval. Contracts exceeding $200,000 annually or $1,000,000 in total multi-year value require Board of Supervisors approval. No price increases will be considered during the first contract year, with subsequent adjustments requiring documented proof of cost increases and 30 days' advance written notice. While a specific total contract value is not explicitly stated, the procurement will involve firm fixed fee arrangements with detailed payment terms to be mutually established. The contractor will be responsible for all audit-related expenses and must submit comprehensive documentation including status reports, audit programs, engagement letters, and draft and final audit reports throughout the project lifecycle.
