8.2.2 CST’s Determination of Bid Validity

The aforementioned letting overrun/underrun justification memorandums are used by CST to determine the validity of the bids. The following items are checked:
  • Errors in plans or engineering estimate;
  • Adequate competition;
  • Indications of collusion among bidders; and
  • Unbalanced bidding.
Once these points have been considered, CST recommends award or rejection of the bid overruns/underruns to be acted on by the Texas Transportation Commission (Commission) during the same month’s scheduled Commission meeting.
