HEAVY CONSTRUCTION & FOUNDATIONS

These union carpenters and contractors work on buildings, foundations, bridges, tunnels, docks, wharves, and other land and water based structures. They direct cranes, install large, heavy timbers in many settings, and often cut, join, and fasten metal elements using welding equipment and oxy-acetylene torches. Marine divers work in a team of dive-tenders and dockbuilders to do full-time underwater construction.
