Central City Bypass Channel South Request for Information

The Fort Worth Central City (FWCC) Bypass Channel South (BCS) Request for Information (RFI-0001) seeks industry input on importing and transporting materials for the construction of a bypass channel, specifically focusing on potential alternative methods to conventional trucking. Key topics include the feasibility of using conveyor systems or off-road haul trucks over existing levees and a temporary bridge over the West Fork Trinity River for efficient material movement. The RFI also outlines the project’s geotechnical conditions, including soil stratigraphy and groundwater levels relevant to the construction of retaining walls supported by deep mixing method (DMM) panels. Additional inquiries address the anticipated costs and engineering challenges of installing DMM, the implications of mass concrete pours during hot weather, and the management of construction risks resulting from tariffs. Contractors are encouraged to suggest strategies for reducing pricing risks and improving contracting structures. This document serves to gather expert industry perspectives necessary for defining project specifications and enhancing construction efficiency while adhering to regulatory requirements and ensuring safety.

The U.S. Army Corps of Engineers – Fort Worth issued a Request for Information (RFI) for the construction of the South Bypass Channel as part of the Modified Central City project in Fort Worth, Texas. This RFI aims to gather preliminary input from qualified PRIME contractors regarding their capabilities and experience. The anticipated construction contract will follow a competitive, firm-fixed price format, utilizing a "Best Value" selection process. The scope involves constructing a 4,400-foot bypass channel with a floodwall and levee. Major project features include soil excavation, structural concrete, and careful coordination with multiple stakeholders owing to the congested urban environment. The estimated construction cost ranges from $100 million to $250 million, with a duration of 2.5 to 3 years. Interested parties must demonstrate substantial past experience with similar projects and certain bonding capabilities. The announcement includes specific requirements for small businesses and guidelines for submissions. Contractors need to register on the government procurement platforms to stay updated. Responses to this RFI are due by August 6, 2025, with a formal solicitation aimed for June 2026. The intent is to foster early industry engagement to ensure quality construction outcomes while adhering to relevant regulations and safety standards.

This government file outlines the 95% design plans for various TUS (Tainter Gate Upper Structure) monoliths, detailing pipe pile and drilled shaft foundations, DMM (Deep Mixing Method) panels, and related structural elements across several sections (S-112 through S-117, S-301, S-302, S-303, S-305). The project includes specific plans for monoliths near the Henderson Street Bridge and White Settlement Road Bridge, addressing existing utilities and infrastructure like sanitary sewer lines, water mains, and gas lines. General notes emphasize pre-construction conferences for drilled concrete piers and shafts, the perpendicular alignment of structural elements to the high wall baseline, and utility verification to prevent installation conflicts. Special attention is given to sacrificial test piles, transition zone test columns, and jet grouting, particularly adjacent to MSE walls and near existing transmission towers, with requirements for instrumentation and monitoring. The design incorporates safety features like grab rails and sleeves for fence posts, and details specifications for fill materials, drainage systems, and structural connections, ensuring compliance with relevant specifications.

The Fort Worth Central City (FWCC) Bypass Channel South (BCS) Request for Information to Industry (RFI-0001) seeks input on various aspects of the BCS project, focusing on material hauling, deep mixing method (DMM) for retaining wall foundations, and overall project execution. The RFI explores alternative hauling methods for riprap and select common fill, considering conveyor systems and off-road trucks, and requests design requirements and limitations for these alternatives. It also delves into DMM panel construction, including cost, mix strength, production rates, and potential issues with excavating cured panels and installing pipe piles. Further questions address construction phasing, mitigating risks during mass concrete pours in hot weather, and economic price adjustment clauses for labor and materials. The RFI aims to gather industry insights to refine specifications, mitigate risks, and optimize contracting strategies for the FWCC BCS project.

The U.S. Army Corps of Engineers – Fort Worth issued a Request for Information (RFI) for the Modified Central City, South Bypass Channel project in Fort Worth, Texas. This RFI is for preliminary planning and not a solicitation for proposals. The project involves constructing a 4,400-foot-long, 250-foot-wide bypass channel with a floodwall and earthen levee. Key features include significant floodwall construction (high and low walls), channel excavation (825,000 cubic yards), levee construction (172,500 cubic yards), and substantial concrete and rebar work. The estimated construction cost is between $100 million and $250 million, with a 2.5-3 year duration. The government seeks input from prime contractors with bonding capability of at least $200 million and relevant experience. One-on-one meetings will be held with the first ten interested prime contractors. The anticipated solicitation release is June 2026, with proposals due around August 2026. Interested firms must respond by August 6, 2025, and be registered in SAM.
