Trinity River Authority of Texas Request for Qualifications Professional Services Fiscal Years 2027-2028

SECTION 1: INTRODUCTION

The Trinity River Authority of Texas (Authority) is a conservation and reclamation district of the State of Texas, created by TEX. REV. CIV. ANN. art. 8280-188, and operating pursuant to special and general law. The Authority’s services are contracted for cities, municipalities, and other special districts. The Authority owns and operates water treatment and supply facilities, wastewater treatment facilities, interceptor collection systems, and water reuse facilities. The Authority invites the submission of a Statement of Qualifications (SOQ) from interested prime consulting firms (Firms or Firm) to provide professional consulting services across the required primary and specialty categories. Firms are the main focus of this SOQ process. Do not provide an SOQ with multiple Firms (i.e., teams). The qualification will be for a term of two years during the Authority’s fiscal years (FY) 2027 and 2028, beginning December 1, 2026, and ending November 30, 2028. Firms are encouraged to submit qualifications and contact information in response to this Request for Qualifications (RFQ) to assist the Authority in creating a list of FY 2027 to 2028 Firms that may provide opportunity for assignment to specific capital improvement projects not currently under contract in Planning, Design and Construction Administration (PDCA). Please note, this qualification process is only for professional services in compliance with 30 Tex. Admin. Code § 292.13(4). Once a Firm has been deemed qualified, it will be invited to provide a specific proposal for a specific project on an as-needed basis. This two-step process is unique to river authorities and required by the rules of the Texas Commission on Environmental Quality.

The Authority will utilize ProcureWare for this RFQ process. The full RFQ packet and submittal instructions will be available for download under BID NUMBER - PDCA_RFQ_FY_27/28. Firms that are not currently registered in ProcureWare must complete registration in order to participate.

Follow the instructions provided in this document and submit the SOQ packet as a single, searchable PDF File no later than Monday, August 24, 2026, by 3:00 p.m. via ProcureWare at:

6/5/2026 RFQ: FY 2027 - 2028 4

and the Authority’s Board of Directors. ESAs shall be negotiated to ensure that the Authority obtains the best and fairest rates for the required services. In the event that a fee acceptable to the Authority cannot be reached with the Firm deemed most qualified, the Authority will commence negotiations with the Firm deemed next most qualified. ESA templates are available on ProcureWare. The standard terms in the ESA template (Articles I, II, VII – XX) are non-negotiable. Submission of an SOQ by Firms constitutes an acknowledgment of that condition.

B. Evaluation for Qualification Selection

The Authority’s qualification teams shall evaluate interested Firms based on the evaluation criteria and scoring points set out in Section 4. C, Evaluation Criteria. Firms that achieve a minimum total score of 150 points shall be considered for an invitation to submit a proposal in response to an RFP, consistent with the selection process.

(1) Qualification will be based on the submittal as well as information obtained regarding prior project experience, from governmental agencies and entities, Texas Board of Professional Engineers and Land Surveyors, certifying agencies, and any resources related to the evaluation criteria.

(2) The qualification team may also request and review additional information as necessary to clarify or supplement the information provided to or obtained by the Authority.

(3) Poor past performance may result in the Authority denying qualification.

(4) Each SOQ is for one responding Firm only. If two Firms have recently merged and are operating as a single consulting Firm, only one Firm’s SOQ can be submitted. The listed experience of both Firms within the last five years may be included in the SOQ.

(5) A submitting Firm’s score shall be made available to that Firm upon request.

(6) All SOQs are subject to Texas Public Information Act requests in their entirety. All information contained in the SOQs will be considered public record. Do not submit any information that the Firm claims is confidential, proprietary, or otherwise not subject to disclosure under the Texas Public Information Act.

(7) The decision of the Authority shall be final and shall not be subject to appeal.

C. Evaluation Criteria

Firms submitting an SOQ that does not comply with the instructions in this RFQ shall be disqualified from consideration. The evaluation criteria are defined herein and the scoring points of each criterion are provided in parentheses, which total 200 points as follows:

(1) Firm’s Professional Experience (80 points) – Firms applying for qualification are required to demonstrate experience to perform professional services within the Category service disciplines. Local experience is a factor in evaluating this criterion, but project experience is not limited to local projects.

CRWS Phase IV Solids Expansion (CMAR) CRWS utilizes a four-step process for solids treatment: Thickening, Pre-dewatering, Thermal Hydrolysis/Anaerobic Digestion (THP/AD), and Post-dewatering. Primary sludge is thickened in gravity thickeners and combined with waste activated sludge from secondary clarifiers, which is thickened via gravity belt thickeners (GBTs). The blended sludge is pre-dewatered by centrifuges, treated through the Thermal Hydrolysis Process (THP), anaerobically digested, and then dewatered in the post-dewatering building using belt filter presses. This will result in the generation of Class A biosolids which enables various options for beneficial reuse.

CRWS Hydrocyclones: Pilot Hydrocyclones is a treatment technology that leverages centrifugal forces to separate solids particles of varying densities from liquids of slurries. It allows for selective separation of suspended solids improving sludge settleability. The piloting of the technology will determine the feasibility of implementing hydrocyclones full-scale to help manage increased solids loading in secondary treatment.

DCRWS Dewatering Improvements The project is expanding the DCRWS dewatering capacity and adding additional odor control. The existing biosolids dewatering consists of two centrifuges that dewater secondary sludge, which are currently operating at capacity with no redundancy. Additional dewatering capacity is necessary to meet the new biosolids projections. Enhanced odor control measures are also included in the scope of improvements.

DCRWS Odor Control Rehabilitation Phase 4 It is anticipated that the next level of odor control at the plant will consist of covering the anaerobic zones in the aeration basins. To verify the need, conduct a round of odor sampling and monitoring to indicate which basins are contributing to offsite odors. Perform an air dispersion model to identify recommendations for improvements. Design a cover for the anaerobic zones and upgrade the bioscrubber system for the additional air volume.
