As part of the ongoing Northeast Water Purification Plant Expansion Project, Stiver Engineering provided a custom pipe support system design for an existing 66-inch water line that provides water to Bush Intercontinental Airport and North Houston. The Mayor’s Office was notified of the risks associated with the project before work began. More than 35 feet of the water line was exposed and supported using beams and nylon straps while the contractor tunneled underneath it. A temporary shoring pit was also designed to help the contractor excavate down to install the support system. The project was completed in August 2019.
