Notice to E-Bidders

Bid Express allows contractors to voluntarily join a Bid Express Plan Holders List available on this site. CDOT's Plan Holder List may be joined by calling 303-757-9313 and that list is maintained at https://www.codot.gov/business/bidding/documents/Planholderjune%204.pdf.

Contractors should be aware that the automatic bid withdrawal functionality in the Expedite bidding application has certain limitations when used in conjunction with Bid Express to submit electronic bids. In rare cases, this limitation could cause a bid to be automatically withdrawn in error, or a bid to be submitted which should have been automatically withdrawn.

This problem can occur ONLY if ALL of the following are true: 1) The bid must have been submitted electronically using Expedite and Bid Express. 2) The bidder must have submitted bids for more than one project (call order) in a single letting. 3) The bidder must have selected the automatic withdrawal option when submitting the bid. 4) An apparent low e-bidder on a project has his/her bid rejected.

At bid opening time, the Expedite electronic bids for all projects (call orders) are downloaded one call order at a time. Bid Express applies the business rules incorporated in any Expedite bid that include the automatic bid withdrawal function. Bid Express, however, does not have the capability to distinguish between a low apparent e-bidder and a low apparent e-bidder whose bid is subsequently rejected by the agency. Contractors should be aware that if they are the apparent low e-bidder on a project and their bid is rejected, the software will not recognize the rejection for the purposes of automatic withdrawal and the bidder's proposal on a later call order will be withdrawn.

There are also ramifications for a second low e-bidder who, due to the rejection of the original low bidder, becomes the new apparent low bidder. If the newly declared apparent low e-bidder desires to automatically withdraw a proposal on a subsequent call order, Bid Express is not aware of this and the withdrawal feature will not work. If this situation occurs, the newly declared apparent low e-bidder may submit their e-bid printout that clearly identifies the intention to withdraw a subsequent bid. CDOT will then withdraw the bid provided such notification comes the day of the bid letting.

Due to these automatic bid withdrawal function limitations, contractors selecting the auto-withdraw feature must do so with full knowledge of potential issues.
