Project Spotlight

SSA West High Rise and Annex Air Intake Project

This project required a reengineering of the existing building's air intake shaft. Helical piers, covered with a concrete mat with anchor bolts were installed, along with the construction of a steel frame up the side of the building above the roof line. The project also included a brick exterior to match the existing building.

The project also included a concrete tunnel under a plant bed for an intake tower.
