The BRA will NOT submit arguments on behalf of the Respondent.

The Texas Attorney General's office shall rule on the matter. In the event that it is determined by opinion or order of the Texas Attorney General or a court of competent jurisdiction that such information may not be withheld, then such information will be made available to the requester. If it is determined that the information may be withheld, BRA will withhold the information from the requestor.

Pricing information contained in Bids or contracts is not considered confidential under the PIA and will be disclosed without making a request to the Texas Attorney General.

VENDOR COMPLIANCE TO STATE LAW

Section 2252.002, Texas Government Code, provides that, in order to be awarded a contract as low bidder, non-resident bidders (out-of-state contractors whose corporate offices or principal place of business are outside of the State of Texas) bid projects for construction, improvements, supplies or services in Texas at an amount lower than the lowest Texas resident bidder by the same amount that a Texas resident bidder would be required to underbid a non-resident bidder in order to obtain a comparable contract in the State in which the non-resident's principal place of business is located. The appropriate blanks in Section A must be filled out by all out-of-state or non-resident bidders in order for your bid to meet specifications. The failure of out-of-state or non-resident contractors to do so will automatically disqualify that bidder. Resident bidders must check the box in Section B.

A. Non-resident vendors in (give state), our principal place of business, are required to be percent lower than resident bidders by state law. A copy of the statute is attached.

Non-resident vendors in (give state), our principal place of business, are not required to underbid resident bidders.
