The county administrator and auditor must move swiftly now on their internal review of compensation paid for a road project in southeast Tarrant County.Allegations of over-billing have been made by an unidentified county road crew worker who said Randle D. Howard Construction was paid $36,000 to build a driveway and drainage culverts at a bad intersection, but two other companies did part of the work and were paid $14,000. Howard’s company also received almost $6,000 for pouring a concrete slab on private property near the project.The Star-Telegram, through documents obtained under the Texas Public Information Act, independently confirmed that the payments were made. The question is: Why were extra payments made when no original contract change orders were approved by a county official?One document, for example, shows the bid submitted by Howard to the county for the private property concrete slab job, totaling $5,775. It shouldn’t take officials long to figure out who requested that bid, who awarded it and who approved payment. Again, the question is whether it was done in accordance with proper county procedure.Howard appeared before county commissioners June 25. He denied any wrongdoing and expressed outrage that anyone would question his integrity.“I have never knowingly or willfully over-billed, double-billed or received unearned payments from Tarrant County officials, or any other of the more than 100 local, state and federal government agencies,” he told commissioners, a position he reiterated to a Star-Telegram Editorial Board member.A report on the matter was expected when commissioners met Tuesday, but the auditor and administrator said they had not finished their work. In fact, County Administrator G. K. Maenius was not scheduled to meet with Howard to review his documentation until Wednesday, the day after the commissioners court meeting.Commissioner Roy Brooks, in whose precinct the work was done, told the newspaper that he was not aware of the allegations until the reporter requested information. He said he asked for the internal review but declined further public comment until the review is complete.That is understandable, but the commissioner has a duty to insist that a report come soon. Commissioners and taxpayers deserve answers, and the questions hanging like a cloud over Howard’s head must be dispelled as soon as possible.No one wants a rush to judgment, but Maenius and Auditor Renee Tidwell have had more than two weeks to get an idea whether there is reason for all this worry. Besides whether there’s any need for concern about improper payments, officials and taxpayers deserve to know whether county employees are performing their oversight jobs on road projects and whether accounting and project approval procedures are well-written.Maenius and Tidwell aren’t doing a law enforcement investigation. They’re reviewing what happened for a report to the commissioners. If they conclude that a law enforcement investigation is called for, they should get out of the way as soon as possible and let the proper legal authorities take over.It’s not too much to ask that Maenius and Tidwell have a report for commissioners no later than next Tuesday.
