Audit Report

Denver Employees Retirement Plan Actuarial Valuation

The objective of our examination of the City and County of Denver’s contract with Interstate Highway Construction Inc. at Denver International Airport was to evaluate the airport’s review of the contractor’s compliance with contract terms, internal controls associated with the review, approval of pay applications and change orders, use of subcontractors, and adherence to project progress reporting and construction project closeout processes. CliftonLarsonAllen LLP conducted this examination on behalf of the Auditor’s Office. I am pleased to present the results of this examination.

The examination revealed an ineffective tracking system for subcontractors that could impact the accuracy of meeting the “disadvantaged business entity” goal listed in the contract.

As a result, the examination provided one recommendation for the airport and Denver Economic Development & Opportunity’s Division of Small Business Opportunity to improve internal controls for tracking and monitoring payments made to subcontractors. By strengthening internal controls and implementing the recommendation provided, Denver International Airport can more effectively monitor compliance with the contract provisions for its construction projects.

This examination is authorized pursuant to the City and County of Denver Charter, Article V, Part 2, Section 1, “General Powers and Duties of Auditor,” and was conducted by CliftonLarsonAllen LLP in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the examination to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our examination objectives. We believe the evidence obtained provides a reasonable basis for our findings and conclusions based on our examination objectives.

We extend our appreciation to personnel at Denver International Airport and within the Division of Small Business Opportunity who assisted and cooperated with us and CliftonLarsonAllen LLP during the examination. For any questions, please feel free to contact me at 720-913-5000.
