Client's Challenge

The LBJ public hospital is the state's first and busiest verified Level III trauma center, with more than 80,000 emergency patient visits each year. The project is developed to expand parking volume by adding a second, 7-level, garage to the campus.

Subsurface Conditions

Medium to stiff sandy lean clay to fat clay (with calcareous nodules and sand pockets) to about 13 feet depth, underlain by a 10-foot-thick layer of loose to dense sand (SM, SC) followed by a very stiff to very hard clay to the maximum explored depth, 80 feet below existing grade.

Geopier® Solution

The structural engineering package included a full design for deep foundations with a Rammed Aggregate Pier® (RAP) alternative. The successful general contractor selected the RAP alternative as the superior construction choice. Only Geopier could offer a RAP system to limit total settlement to 1” for loads approaching 3,000k and exceeding 50klf.
