Internal Audit Services

The Ontario International Airport Authority (OIAA), a joint-powers authority between the City of Ontario and San Bernardino County, is seeking proposals from qualified certified public accounting firms licensed in California to provide comprehensive internal audit services. The selected firm will conduct risk-based internal audits covering financial management, procurement and contracting, construction oversight, information technology governance, compliance monitoring, and revenue contract management. Deliverables will include entrance and exit conferences, detailed audit programs conforming to Institute of Internal Auditors Standards, progress reports, draft and final audit reports with recommendations, and work paper delivery. The pre-proposal virtual meeting is scheduled for December 2, 2025, at 11:00 a.m. (non-mandatory but strongly encouraged), with questions due by December 16, 2025, at 2:00 p.m. Proposal submissions are due electronically by January 6, 2026, at 2:00 p.m. Evaluation criteria include administrative responsiveness (pass/fail), professional references (pass/fail), technical qualifications (33.3%), project delivery and work plan (22.2%), overall competence and understanding of scope (44.4%), and cost proposal. Qualified firms must demonstrate experience in performing internal audits within complex, regulated business environments, preferably with airport industry expertise.

No specific small business set-asides are mandated, though the OIAA encourages small business participation and discourages limiting subcontractor opportunities. The contract will have an initial two-year term with three optional one-year renewal terms, for a total not-to-exceed amount of $1,250,000 over the potential five-year term. Compensation will be based on fixed, fully loaded hourly rates, with the Authority paying only for actual work completed. Prior to contract award, the successful proposer must provide proof of insurance, a City of Ontario Business License, and various administrative documents including a notarized Affidavit of Non-Collusion, Confidentiality and Non-Disclosure Form, Supplier Information Form, W-9 Form, and Conflict of Interest Disclosure Form. The OIAA operates Ontario International Airport, which serves over 7 million passengers annually and handles more than 800,000 tons of air cargo each year. The internal audit services will support the Authority's financial oversight, risk management, and governance practices across various operational and financial areas, with audits to be assigned on a task order basis and reported directly to the Finance and Audit Committee.
