LBJ Express Project
Dallas, TX, United States
This PPP Project, financed in part by Ferrovial Agroman for TXDOT, employed unique bridge construction techniques. Large, precast concrete cap structures were prefabricated in a nearby facility and hauled to the jobsite where they were set in place on top of concrete columns. During Phase II of the project, some of the 350,000 lb caps needed a temporary support until they were post-tensioned into the previous phase caps.

Impressions from the project process
PERI's VST Shoring Tower supported the 350,000 lb caps until they were post-tensioned.
The client cycled 16 units of VST shoring towers to support the 31 caps.
The VST towers were easily assembled on site with pinned connections.
VST units assembled and ready to be stacked to create the tower.

Two 550tn cranes lift a precast cap onto the PERI VST tower. After the cranes leave the site, fine adjustments to the tower elevation can be made hydraulically with the special VST head unit.
