CORROSION CONTROL ENGINEERING SERVICES FOR CEDAR CREEK SECTION 2 REPLACEMENT (PHASE 2), CEDAR CREEK SECTION 4 REPLACEMENT, SECTION 1D & 1E PIPELINES AND ARLINGTON OUTLET IMPROVEMENTS

The Tarrant Regional Water District (TRWD) is soliciting Statements of Qualifications (SOQs) from qualified consulting firms to provide comprehensive corrosion control engineering design services for multiple major raw water transmission pipeline projects. The scope encompasses three primary project areas: Phase 2 replacement of approximately 4.42 miles of 72-inch pre-stressed concrete cylinder pipe (PCCP) with 102-inch mortar-lined welded steel pipe in Cedar Creek Section 2 from the Kennedale Balancing Reservoir to Mouser Way; replacement of approximately 8.6 miles of 72-inch C301 PCCP with 90-inch mortar-lined polyurethane coated welded steel pipe in Cedar Creek Section 4 in the Trinity River Bottoms area; and new construction of approximately 3 miles of 108-inch pipeline in Section 1D connecting to existing Line J pipeline and parallel existing RC and CC pipelines, plus approximately 3,000 feet of 108-inch pipeline in Section 1E connecting Section 1D to the Rolling Hills Booster Pump Station, with associated valve improvements at the Arlington Outlet facility.

The selected consultant must demonstrate extensive expertise in cathodic protection design for large diameter pipelines (72-inch diameter and greater), including galvanic system design, monolithic isolation joint specification, and impressed current system design. Key technical capabilities required include construction management and inspection of cathodic protection installations, continuity testing, in-place isolation testing, baseline surveys, stray current interference detection and mitigation, project management, construction cost estimating, scheduling, Geographic Information Systems (GIS) expertise, and document control/information management. The consultant team will coordinate closely with TRWD's separate contracts for pipeline design and geotechnical engineering.

Project implementation schedule shows construction for Cedar Creek Section 2 Phase 2 expected to begin in late 2026 with completion by 2027, Cedar Creek Section 4 construction beginning in 2027, and Section 1D & 1E improvements occurring concurrently or phased based on system needs. The Cedar Creek pipeline system is TRWD's oldest raw water transmission main dating to the early 1970s, conveying approximately 127 MGD capacity through approximately 74 miles of primarily 72-inch diameter pipe from Cedar Creek Reservoir southeast of Dallas to Rolling Hills Booster Pump Station in southeast Fort Worth.

Consultants must submit comprehensive SOQs demonstrating established project management experience on large diameter pipeline projects with cathodic protection installations, expertise in raw water transmission pipeline cathodic protection analysis and design, working knowledge of TRWD's technical specifications and details, GIS capabilities for collaboration with TRWD staff, and experience with construction management of large diameter cathodic protection installations. TRWD encourages teaming with sub-consultants to meet Diverse Business goals and bring comprehensive expertise. SOQs must not include fee estimates, pricing, or billing rate information; selected consultants will submit scope and fee estimates following SOQ evaluation.
