A.H. Beck was contracted to install 222 drilled shaft retaining wall piers for Houston Methodist's Centennial Tower up to 140 feet deep for this hospital in Houston Texas
Vaughn Construction contracted A.H. Beck to install 222 drilled shaft retaining wall piers for Houston Methodist’s Centennial Tower, a new 26-story tower in the Texas Medical Center. The shafts were 48 inches in diameter and varied from 102 to 140 feet deep. A.H. Beck worked closely with Vaughn Construction, Houston Methodist, and the engineers through the final design process. The final design consisted of drilling piers as close as 6 inches to each other and only 3 inches from the existing hospital building. Working with little to no room in the Houston medical district, the supporting rebar cages had to be picked and turned vertically without damaging the buildings surrounding the job site. Our team mobilized two crews, each consisting of a drill rig and a 110-ton crawler crane, to complete all the deep foundation work on this project. Shafts were drilled using two Beck manufactured self-contained rigs with temporary surface casing and bentonite slurry.
