Location: Webster, Texas

Description: Project consisted of two 12 foot diameter drilled shafts 130 feet deep. While the majority of the structures were constructed with a pile cluster/footing foundation, two piers required single large diameter drilled shafts due to the limited width of the construction zone and to eliminate the differential settlement of the embankment. A. H. Beck manufactured a 12’ diameter auger, mix 3000 Bbl of bentonite mineral slurry, set 12’ diameter x 20’ long permanent casing and excavated the 12’ diameter x 130’ deep slurry displaced drilled shafts. Doran Steel designed the steel plate templates that were furnished to facilitate the tying and placing of a 75,000 lb reinforcing cage with 40 #18 bars and the fabrication of the rebar cage. Dorsett Brothers Concrete Supply provided a 7 sk concrete mix was designed with admixtures to maintain a minimum 4” slump for the duration of the pour. 625 CY was batched, delivered, and placed in less than 5 hours with the use of two articulated boom pumps pumping into two 12” tremie pipes.
