Ostensibly, it is the largest ICF project in the world. 3.2 miles of 8' sound wall and numerous retaining walls give the mall its unique and custom look. Planning required that the walls completely resemble the already approved 8" painted CMU wall and the 6" CMU recess wall. We built a remote-controlled robot with a battery and hot-knife to roll across the top of the wall and slice the 2" recess out of the ICF wall foam. All foam was kept and recycled. The project was expected to take 9 months with CMU, and we could accomplish it in 3 months.
