Tex. Transportation Code § 223.249

(a) The department shall pay an unsuccessful proposer that submits a responsive proposal a stipend for the work product contained in the proposal that the department determines can be used by the department in the performance of the department's functions. The stipend must be a minimum of twenty-five hundredths of one percent of the contract amount and must be specified in the initial request for proposals, but may not exceed the value of the work product contained in the proposal that the department determines can be used by the department in the performance of the department's functions. If the department determines that the value of the work product is less than the stipend amount, the department shall provide the proposer with a detailed explanation of the valuation, including the methodology and assumptions used by the department in determining the value of the work product. After payment of the stipend, the department may make use of any work product contained in the unsuccessful proposal, including the techniques, methods, processes, and information contained in the proposal. The use by the department of any design element contained in an unsuccessful proposal is at the sole risk and discretion of the department and does not confer liability on the recipient of the stipend under this subsection.

(b) In a request for proposals, the department shall provide for the payment of a partial stipend in the event that a procurement is terminated before the execution of a design-build contract.
