RFQ 06275 & 06276 Design Engineering Services for PGBT Segment 8 Wall Stabilization

The North Texas Tollway Authority (NTTA) is requesting qualifications for design engineering services to stabilize Mechanically Stabilized Earth retaining walls along President George Bush Turnpike Segment 8 between Interstate 30 and Interstate 20, with responses due October 22, 2026 at 11:00 a.m. CT. The solicitation comprises two separate RFQs — RFQ 06275 for Phase 3A (11 walls) and RFQ 06276 for Phase 3B (9 walls) — each selecting a separate prime firm. A small business participation goal of 24 percent is established.

Firms currently serving as General Engineering Consultants, Program Management Consultants, Maintenance Management Consultants, or Construction Engineering Consultants for NTTA are ineligible. If a firm is selected as prime consultant for one contract, it may perform no more than 15 percent of services as a subconsultant on the other contract.

The scope includes geotechnical investigation, development of three stabilization alternatives per wall with cost estimates, preparation of plans and specifications with engineer's estimates, and construction support. Respondents must submit electronic and physical copies limited to ten pages for initial tabs plus supporting documentation; pricing is excluded from submissions and will be negotiated separately after selection.

The contract term is three years from final execution. Respondents must carry commercial general liability insurance with limits of not less than $5 million per occurrence and workers' compensation insurance with statutory limits, and must execute conflict of interest questionnaires and confidentiality agreements.

Evaluation criteria for written responses allocate 30 points each for respondent team qualifications, key personnel qualifications, and technical approach, plus 10 points for small business program participation. If interviews are conducted, evaluation shifts to 30 points for qualifications and experience, 40 points for key personnel experience, and 30 points for technical approach.

The pre-submittal conference is scheduled for September 29, 2026 at 3:00 p.m. CT via Microsoft Teams. Questions are due October 8, 2026 at 5:00 p.m. CT. Responses may be submitted via NTTA Marketplace or physical delivery to NTTA's Plano office.
