0508-11 Crane or derrick: Installation, construction or erection, dismantling, maintenance or repair
Applies to contractors engaged in the installation, construction or erection, dismantling, maintenance or repair of nonmobile cranes and derricks for commerce and industrial use. Cranes and derricks can be very similar in that they are both defined as machines for hoisting and moving heavy objects through the use of stationary or movable booms equipped with cables. An object, sometimes weighing many tons, can be secured to the cables and moved into position along the length of a stationary boom or to another location within the reach of a movable boom. A derrick, however, can also be a permanent framework over an opening, such as an oil-drilling operation, to support boring equipment. The cranes included in this classification are those that are permanently installed at a marine port, cargo handling facility or an industrial facility to move supplies, cargo containers, or heavy objects (vertically or horizontally) that are being assembled and must pass through the length of a building to complete the process. Work contemplated by this classification includes, but is not limited to, the placement of forms and reinforcing steel for a foundation (in the case of some structures described above, the additional reinforcing required to support the crane is usually contemplated in the plan for the building's foundation where the crane is being anchored), on-site fabrication and assembly of parts, erecting the frame, installation of scaffolding, raising structural members by hoist and welding or bolting them into place. This classification includes the delivery of material and supplies to the job site and installation of apparatus onto a structure covered by this classification when done by employees of an employer having operations subject to this classification.

0508-12 Water cooling towers or structures - metal or wood: Construction or erection, dismantling, maintenance or repair
Applies to contractors engaged in the construction or erection, dismantling, maintenance or repair of metal or wood water cooling towers or vertical structures. These structures are usually part of an industrial complex in which water is used as a cooling element in a manufacturing process. The water, which absorbs heat from the machinery being cooled, can be circulated and reused after is has been channeled through a cooling tower to be chilled sufficiently. A common design allows the hot water to tumble down numerous open louvers or steps to lower its temperature. These towers are often composed of prefabricated parts which are delivered to the site and then assembled by bolting or welding together, then the necessary motors, pipes, fans and pumps are installed. Work contemplated by this classification includes, but is not limited to, clearing of land (if done by the excavation contractor), excavating for the foundation, the placement of forms, installation of reinforcing steel, pouring and finishing the foundation, on-site fabrication and assembly of parts, erecting the frame, installation of scaffolding, raising structural members by crane and welding, bolting or otherwise fastening them into place. This classification includes the delivery of material and supplies to the job site and installation of apparatus onto a structure covered by this classification when done by employees of an employer having operations subject to this classification.
This classification excludes the felling of timber which is to be reported separately in the applicable logging classification; the installation of machinery which is to be reported separately in classification 0603; the preliminary clearing of land by a contractor who is not also excavating for the foundation which is to be reported separately in classification 0101; delivery of material to the site by employees of a material supplier or a common carrier which is to be reported separately in the applicable classification; and the construction of other related buildings at the project site which is to be reported separately in the applicable construction classification.
Special notes: This classification does not allow separate reporting of excavation or foundation irrespective of who performs the work. Construction of a water cooling structure that uses a horizontal rather than tower-like design is to be reported separately in classification 0518.
