Site work for a water / sewer project in Orla, Texas. Completed plans call for site work for a water / sewer project.

The Red Bluff Water and Power Control District (District) is planning installation of a full length grout curtain at the Red Bluff Dam near Orla, TX. The anticipated scope of work for foundation grouting at the Red Bluff dam includes grouting of the entire dam foundation (up to 9,000 LF) in a minimum double row grout curtain to depths from the dam crest as great as 180 feet. Drilling operations through the embankment shall comply with United States Army Corps of Engineers (USACE) ER-1110-1-1807 "Drilling in Earth Embankment Dams and Levees". In order to protect the dam and dam/foundation interface, Multi-port Sleeve Pipe (MPSP) are anticipated for all grout borings that extend through the embankment and into the foundation. Drilling operations will include real-time monitoring to monitor all water and grout injection parameters, drilling down-pressure and torque. Multiple high mobility and low mobility grout mix designs will be tested and utilized as part of this grout program. Specialized grouting techniques for soil-like portions of the foundation will be utilized. Grout program scope details will be provided as part of the bid documents after contractor prequalification. All Contractors who wish to submit cost and technical proposals for this Project at a later date must be prequalified. Joint Ventures are allowed, however at least the JV partner that is performing grouting works is required to be prequalified. A Contractor's Qualifications Statement will be used to prequalify Contractors with the capabilities to meet the Project needs including the ability to perform certain types of drilling in the dam and foundation, water pressure testing, pressure grouting with a range of stable cement-based grout mixtures, and the ability to provide real-time computer monitoring and recording of all such operations. Contractors should be experienced and actively engaged in performing pressure grouting of active high hazard dam foundations for intermediate to large size earthen dams. Only prequalified Contractors will be permitted to submit cost proposals to the District for thisProject. To be evaluated, Contractors must complete a Contractor's Qualifications Statement whichis included in this document, and which can be obtained from Lisa Singer at lisa.singer@hdrinc.com. The deadline to ask questions is 7/22/2022 5:00 PM CST Questions concerning prequalification may be addressed to HDR, Attn: Teresa Krause, P.E. by email at Teresa.Krause@hdrinc.com. Estimate: Range: $20 to $60 Million *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document.
