Business Information

Chicago (Board) Construction

This construction method uses both manpower and machines for excavation while also constructing retaining walls using steel corrugated sheets and ring frames. The ground is excavated until a determined depth and then reinforcing rods are assembled inside the underground shaft. The retaining material is then removed while concrete is poured in to construct the shaft.
