Drilled Shaft Optimization for ComEd.
The project involved new 345 kV transmission lines just outside downtown Chicago. Drilled shaft foundations would support ten tubular steel pole structures, many of which were subject to substantial loads. Original foundation designs included significant embedment into rock, which had substantial construction implications and led to alternative options being explored.
Geotechnical conditions were reevaluated and the designs were value engineered to optimize constructibility. The proposed VE designs reduced expected rock embedment lengths by 46% and rock excavation by 60%.
