AIL Sound Wall Dons the Pads for University of Houston Practice Field

Lightweight and easy-to-install AIL Sound Walls were recently selected for a particular section of Houston’s major Metrorail expansion. On this project, the University of Houston was concerned about protecting their football players and the City of Houston was concerned about protecting their main sewer and storm drainage lines.

The University asked that AIL designs the barrier to allow for mounting heavy protective pads on the back, so AIL had to integrate extra reinforcement into the barrier to support that load. The City did not want a standard precast concrete sound barrier in this section, fearing its weight might damage the pipelines and repair/maintenance access might be more difficult. 

AIL’s Tuf-Barrier (Reflective) sound wall system was ready to get its game face on and crossed those lines with ease.

Part of a Design-Build Project by Houston Rapid Transit Joint Venture

The Metrorail expansion was part of a $2 billion design-build project by Houston Rapid Transit Joint Venture (HRT JV) that included four new stations and 17 miles (27 kilometers) of new track. The HRT JV team included Parsons Transportation Group, Granite Construction Company, Kiewit Texas Construction L.P., and Stacy and Witbeck, Inc.

 

AIL worked hand in hand with Parsons to design a continuous footing foundation as they were not able to drill traditional pillar footings due to the underground services. AIL also collaborated with the fence pad supplier to ensure that the AIL system was designed properly to accept and support their heavy load. This was a late add-on to the project, so AIL had to react quickly, with revised shop drawings and production. 

The barrier was supplied in a timely fashion and installed in just under two weeks. According to HRT JV, the Metrorail and University teams are both happy with the new barrier and received only positive feedback on the sleek look of AIL’s barrier over the standard precast alternatives.
