TxDOT must qualify bidders to become eligible to bid or to receive a bid proposal on a construction or maintenance project.

The agency has three levels of qualification, all of which require annual requalification.

1. Confidential Questionnaire (CQ)

This level of qualification is normally for construction projects. Bidders must provide an audited financial statement prepared by an independent certified public accountant as outlined in Bulletin No. 2.

Financial statements must be less than one year old and must be approved for at least one letting prior to the anniversary date. Bidders must also provide a completed Confidential Questionnaire and related supporting documents.

2. Bidder's Questionnaire (BQ)

This level of qualification is for bidding on projects for which the full requirements outlined above are waived—normally smaller construction, routine maintenance, emergency, and specialty projects. In order to satisfy the requirements for bidding on a waived project, bidders must provide a completed Bidder's Questionnaire and related supporting documents.

The proposal request form denotes projects eligible for this level of qualification with a “W.”

3. Materials Supplier's Questionnaire

This level of qualification is for suppliers bidding on material and traffic control and safety device projects, which is limited to the purchase and delivery of materials used on roadways for in house state force work only. In order to satisfy the requirements for bidding on a materials project, bidders must provide a completed Materials Supplier's Questionnaire and related supporting documents (Use Internet Explorer to open the MQ). Any contractor with an approved Confidential Questionnaire or Bidder's Questionnaire may bid on material projects.

Qualification of Bidders

TxDOT determines each contractor’s bidding capacity—the maximum dollar value a contractor may have under contract with TxDOT at any given time. A contractor may request and receive bidding proposals for upcoming projects for which the engineer’s estimate does not exceed bidding capacity, less any other TxDOT work currently under contract.

Once TxDOT qualifies a bidder, the approval is valid for one year from the date of the financial statement. Bidder's Questionnaires are valid for one year from the date of receipt by TxDOT.

The Materials Supplier's Questionnaire does not require the submission of financials and therefore no bidding capacity is assigned to MQ suppliers bidding on material projects. The MQ is valid for one year from the date of the receipt by TxDOT.

TxDOT grants a 90-day grace period for the preparation of a new qualification statement. All qualification statements must be received at least 10 days prior to the date of the project letting.

Instructions to Bidders

The 2014 Standard Specifications Book provides guidance on how to submit bid proposals. Item 2 Instructions to Bidders specifically details the process for requesting and preparing the bid documents.


TxDOT will not read or accept bids submitted on the same project by affiliated firms. Affiliates must prequalify as of the same balance sheet date to prevent recording the same assets multiple times in setting contractor bidding capacities.

Each of the prequalification forms lists the definitions of firms considered to be affiliated. All existing affiliates, whether prequalifying or not, must be disclosed during prequalification.

To report an Affiliation, please contact (512) 416-2584.

Technical Qualification for Intelligent Transportation Systems (ITS)

TxDOT requires technical qualification for certain categories of ITS work. This technical qualification is in addition to all other bidder qualifications required by TxDOT.
