When the Texas Department of Transportation needs work to be done on a state highway, TxDOT solicits bids from developers. By state law TxDOT is required to choose the lowest bidder. TxDOT spokesperson David Glessner said this state requirement is stipulated in the section of the Texas Transportation Code regarding bids and contracts for highway projects. The lowest bid is chosen after the bids are read in a public letting meeting, or a meeting where the bid is publicly made available. In such a case TxDOT can choose the second-lowest bidder if the lowest withdraws its application prior to the contract award. A bid is also unacceptable if its low cost is due to an incomplete project bid. The engineer for the project has a cost estimate for the project as well. If bids are significantly lower than the engineer’s estimate, then they are most likely deemed unacceptable, Glessner said.
