Work phases may include planning and preliminary engineering design, final engineering design with bidding support, and construction phase services in accordance with USACE and TCEQ requirements for large high-hazard dams.

Key personnel, including engineers and surveyors, must be licensed in Texas and hold a minimum of five to ten years of relevant experience in their respective disciplines, with stated preference for high-hazard dam experience. All deliverables must be signed and sealed by Texas-licensed professionals. The awardee must maintain professional liability insurance of $5,000,000 per claim / $10,000,000 aggregate; general liability of $1,000,000 per occurrence / $2,000,000 aggregate; workers' compensation; automobile liability of $1,000,000; employers' liability of $1,000,000; and pollution liability of $1,000,000 per claim.

Selection criteria emphasize respondent qualifications, demonstrated experience on similar dam projects, ability to perform without delay, and the proposed service delivery plan. No price information is permitted in proposals. The BRA will negotiate a contract on a time-and-materials basis with a mutually agreeable not-to-exceed amount for overall services and individual tasks. The contract may be terminated at any time without penalty.
