A.H. Beck installs 10 foot and 11.5 foot diameter drilled shafts in tight spaces, high water table, and sandy soil for a new overpass in Gregory, Texas.
The project required installation of three 10ft diameter drill shafts and one 11.5ft diameter drill shaft for a new over pass in Gregory, TX. Each shaft was 85’ long and each posed a variety of challenges due to tight access, the high water table and sandy soil conditions. The layout for each piece of equipment was critical for performing each stage of installing the drill shaft. Finding enough room between the existing bridge structure, the power lines and adjacent creek made a challenging project. The reinforcing cages were 48,000 pounds and were assembled in between the existing bridges, or between the bridge and either powerlines or the creek, then hoisted vertically and placed in each shaft during scheduled road closures for the safety of the public.
