The Sandow Unit 4 Environmental Retrofit Program required a tight schedule to comply with various governmental regulations. A. H. Beck was contracted to design and build a shoring wall to protect sensitive ID fans and perform substructure work to install 308 drilled caissons. The shoring wall designed by A. H. Beck included 118 - 18” diameter tangent piles 26 feet deep constructed with only 11’ of head room. The main SCR foundations required 308 – 24” drilled shafts, some 65 feet deep. The engineers required Type V Cement so A. H. Beck produced all of it onsite with volumetric mixers.
