A. H. Beck delivered 1,310 steel-reinforced grouted augercast piles for the expansion of Exelon Generation’s Colorado Bend facility. The 18” diameter, 65’ deep piles were installed, supporting an additional 1,000 megawatts of generation capacity using low-carbon combined-cycle gas turbine generation. Prior to production pile installation, an elaborate pile load test program was conducted. The program consisted of axial compression, tension and laterally loaded 18” and 24” piles in three separate areas across the vast site. A. H. Beck utilized their 500 ton load frame and staff of professional engineers to perform the testing program. The results of the tests were evaluated by the owners engineers and allowed the 24” diameter piles to be redesigned to 18” piles across the site resulting in a significant cost savings.
