2016-11-22 Concrete Placement. With drilled shaft excavation, the concrete placement needs to meet specific requirements based on the conditions of the project. These are some of the procedures that might be used: Dry Excavations: The simplest method for concrete placement is in a dry shaft excavation. Most of the time, the free fall method can be used.
