Internal Audit Services

The Ontario International Airport Authority (OIAA), a Joint-Powers Authority governing Ontario International Airport (ONT) in Southern California, is soliciting proposals for internal audit services through solicitation number 2025-RFP-071. The airport operates as a medium hub with over 7 million annual passengers and significant air cargo throughput, necessitating strengthened internal audit capabilities to support operational integrity, compliance, and risk management. The contract seeks to engage a qualified California-licensed certified public accounting firm to deliver comprehensive risk-based audit services under the oversight of the OIAA Finance and Audit Committee. Scope of work encompasses audits across several key areas including financial management, procurement, construction oversight, IT governance and security, contract management, physical security, and compliance with regulatory requirements, all guided by standards such as GAAS, GAGAS, and the Institute of Internal Auditors’ core principles. The engagement is structured as a task order contract with an initial base term of one year followed by five optional one-year renewals, and a total not-to-exceed value of $1.2 million over the full potential term. Services will be billed on a fixed fully loaded hourly rate basis by staff category, with no fixed line items, allowing flexibility to address emergent audit needs. Proposal evaluation emphasizes responsiveness, firm and staff qualifications, relevant experience in airport or heavily regulated sectors, and technical approach, with cost considered post-technical evaluation in negotiations. Submissions require extensive administrative documentation including conflict of interest disclosures, proof of licensing, insurance certificates meeting set thresholds, business licenses, and affidavits supporting small business enterprise participation where applicable. Deliverables include audit programs, detailed reports with findings and recommendations, work papers, and regular progress reporting, with inspection and acceptance managed at OIAA facilities. The contract imposes strict confidentiality, non-disclosure agreements, and requires final approval by the OIAA Commission before work commencement. The solicitation encourages thorough compliance with procedural requirements and prioritizes technical merit and risk mitigation in vendor selection to support OIAA's expanding operational demands.
