Tutor-Perini is protesting the award of a $271 million contract to Clark-McCarthy.
At a council hearing on Friday, Zine asked airport officials why Tutor-Perini wasn't awarded the contract, since Tutor's bid was $30 million lower than the winning bid.
"The issue that came to my attention was cost ... and I've been informed that there was another bidder who was $30 million less than Clark on this particular project," Zine said. "How is it we have this $30 million difference between the two bidders?"The answer, according to airport officials, is that the Tutor-Perini proposal didn't comply with the temperature ranges specified by the airport, so the bid was tossed out.
"I work very hard to ensure that taxpayer money is spent efficiently and not wasted. The airport item in council Friday called for the approval of a contract worth hundreds of millions of dollars. I agreed with a majority of the members of the city council that there were still outstanding questions that needed to be answered before we could move forward with final approval. I look forward to a thorough vetting of these outstanding issues when the council reconvenes so that we can make a final decision on this contract based on all of the information that is available to us."
