RE: Request for Qualifications (RFQ) - Professional Engineering Services

PROJECT: ON-CALL GEOTECHNICAL SERVICES

ATTENTION:

Proposals are being accepted by El Paso Water (EPWater) for Statements of Qualifications (SOQ) from interested firms for:

ON-CALL GEOTECHNICAL SERVICES

Most projects identified at this time have been approved in the FY2026/2027 capital improvements program; however, others will be identified throughout the year. The nature of these contracts will be for on-call services for a period of three (3) years effective from the date of the contract award date (PSB meeting date). Within the three-year contract time, multiple task orders may be issued under each contract.

However, total task orders amount will be limited to a maximum of $1,000,000. If work on a task order is issued prior to the expiration of the contract, the work order will remain in effect until completion of the work order. EPWater may select multiple qualified consultants for this on-call contract. The estimated costs for these projects can range from $100,000 to $10 million (engineering and construction).

All inquiries and communication regarding this Request for Qualifications must be submitted via:

https://epwater.ionwave.net/HomePage.aspx

If you have trouble accessing the Contract Documents, please contact the Purchasing Department of the
