About our Sessions

The West Harris County Regional Water Authority’s Segment B1B2 project consists of 10-miles of 84-in and 96-in large dimeter steel waterline in Houston, TX to which construction methods will include both open-cut and tunneling methods. The project alignment calls to cross two growth faults; the Brittmoore and White Oak Faults. The design engineer implemented a strain-based approach to accommodate large permanent ground deformations for the crossings through the fault zones. Two alternatives for pipe material were allowed to be used within the fault zones by the design engineer along with stringent weld requirements and inspections. The construction management team ensured these requirements were adhered to by the contractor. Fault zone crossings with large diameter waterlines have not been common for the Houston area. This presentation will elaborate on the efforts taken by the design and construction management teams to ensure innovative solutions for the complex challenges that fault zones can produce impacting successful installation of large diameter waterlines
