Site work and renovation of a water / sewer project in Rancho Viejo, Texas. Completed plans call for the renovation of a water / sewer project.

The Project includes, but is not limited to, construction to rehabilitate an existing municipal brackish-water reverse osmosis facility by replacing the existing RO treatment skid and obsolete interior process equipment; furnishing and installing a new permanent Clean -in-Place system; and providing associated process piping , electrical , instrumentation, controls, startup, commissioning, performance testing, training, and related Work while reusing the existing building, equipment pad, wall penetrations, and selected piping. Deadline to submit questions and requests for interpretation is Wednesday, November 4, 2026. -- Submit all questions about the meaning or intent of the Bidding Documents in writing to Charles Ortiz, General Manager, at cortiz@vmud2.org, with a copy to the Engineer if directed by Owner Project consists of rehabilitation of the existing Valley Municipal Utility District brackish-water reverse osmosis treatment facility, including replacement of the existing RO skid, Clean-in-Place system and associated interior process piping, instrumentation, controls, and related electrical work. B. The Work shall provide a complete, operational rehabilitation coordinated with Section 46 61 00, 46 61 10 and the Contract Drawings. 1.02 WORK INCLUDED Site verification and coordination of existing conditions before fabrication. Selective demolition of the existing RO skid and designated piping, valves, supports, wall-mounted analyzers/instruments, controls, conduit, and wiring made obsolete by the new system. Protection and retention of existing wall penetrations, exterior piping, final-blend piping, building, and existing concrete equipment pad unless specifically indicated otherwise. Installation of the new RO treatment skid and associated field connections. Installation of the new Clean-in-Place (CIP) skid and associated field components. New raw-feed, permeate, and concentrate field piping from existing north-wall tie-ins to the replacement skid. Overhead pipe supports, guides, restraints, and ancillary structural metalwork. Electrical demolition, modifications, feeders, branch circuits, grounding, raceways, and field control wiring necessary for the new work. No electrical Contract Drawings are provided. Electrical work is performance specified and shall be field verified, designed/coordinated , sized, furnished and installed by the Contractor based on the approved RO and CIP equipment electrical requirements and existing facility conditions. Field instrumentation and control interfaces not included within the OEM skid package. Testing, startup support, commissioning, training coordination, record documents, O&M data, and closeout. Furnish a complete replacement brackish-water reverse osmosis (RO) treatment system for the existing Valley Municipal Utility District RO facility, including design, equipment, fabrication, installation, demolition, piping, electrical, instrumentation and controls, testing, startup, training, and commissioning required for a complete and operable system. B. The Work is a rehabilitation of an existing operating facility. The Supplier/Contractor shall field verify existing conditions and coordinate all interfaces before fabrication. Major Work includes: Remove the existing RO skid , existing CIP system, and associated interior process piping, valves, wall-mounted analyzers/instruments, supports, controls, and appurtenances identified for demolition. Protect and retain the existing building, existing concrete equipment pad, existing wall penetrations and exterior piping, and the existing final-blend piping unless specifically shown otherwise. Furnish and install one new RO skid sized to fit the existing equipment area and concrete pad. o Furnish skid-mounted cartridge filtration, high-pressure pumping, membrane pressure vessels/elements, valves, instruments, PLC/HMI controls, sample points, piping, tubing, wiring, and accessories required for a complete RO treatment package. Connect new raw-feed, permeate, and concentrate piping to the existing process piping approximately 12 inches inside the north wall, as shown on the Contract Drawings. Field verify exact tie-in locations. Route new raw-feed, permeate, and concentrate piping overhead to the RO skid with stainless steel pipe-supports independent of wall panels and roof deck. All piping from tie-in locations to the proposed RO skid shell be sized for the proposed RO skid and future RO skid with blind flanges in the end. Provide electrical power/control modifications required to serve the new skid. o Perform factory or site fabrication QA/QC, functional testing, startup, performance testing, operator training, and closeout
