Concrete and structural steel construction: Three cranes and a personnel lift operating in same area. On right, Grove mobile telescoping hydraulic crane lowers concrete bucket to place concrete. On left, another Grove mobile telescoping hydraulic crane is not currently operating, so it supports concrete masonry unit deadweight. In left center of photo, corrugated galvanized steel decking is being raised by unseen tower crane to be erected on steel frame to left. In center, Genie personnel lift supports an ironworker.
