Transportation Corridor Agencies Release Internal Audit Findings of Contractor Billings

Report identifies a net underbilling of $4,684 and areas for process improvements

IRVINE, Calif. - February 27, 2019

The Transportation Corridor Agencies (TCA) recently performed a scheduled and routine internal audit of invoice accounts payable focusing on processing procedures and controls. TCA’s Internal Audit team serves as an objective review function to examine and evaluate the Agencies’ operations.  

As part of this audit, TCA’s internal auditor reviewed two high-profile communications contracts – Contract No. K000983 with Venture Strategic and Contract No. K001162 with Curt Pringle and Associates.  

Findings from the audit showed the following: 

Contract No. K000983

  • Venture Strategic underbilled $13,020 by assigning incorrect billing rates to Venture Strategic staff members and subconsultant staff members.
  • Out of more than 11,000 entries, TCA identified a total of 13 duplicate billing entries for a total of $8,336 in overbilling.
  • Therefore, the findings determined a net underbilling of $4,684 to TCA.

Contract No. K001162 – The findings showed no evidence of billing discrepancies.

After evaluating the audit findings, TCA immediately requested that Venture Strategic submit an adjusted invoice correcting the errors.

As a result, TCA management will implement improvements, including simplifying Venture Strategic’s invoice format.
