Phraseology

Iron or Steel Erection – Frame Structures – All Operations to Completion
Note:  

Includes work on balconies, fire escapes, staircases, fireproof shutters.

Description

Code 5040 applies to employers engaged in the erection of iron or steel frame structures three or more stories in height, including assembling or fabricating at the job site.  This classification  contemplates the raising of the structural members into place using a crane or boom and securing by bolting, welding or riveting the frame or skeleton of buildings.  Specialist contractors engaged in the erection of concrete structural beams or girders, which have been cast by others, also fall within the scope of this classification as well as specialist contractors engaged in the connecting of bar joists to the steel framework.

This classification also applies to specialist contractors engaged in the erection of exterior iron or steel balconies, fire escapes, fireproof shutters and staircases.  Staircase erection by specialist contractors is ordinarily undertaken after the structural steel frame is completed but prior to wall erection.  The erection of iron or steel bridges or other bridges where the operations involve the erection of structural steel trusses, columns or I-beams and steel decks, elevated railroads, highways or viaducts is also included under this classification.

Welding in connection with the operations covered is to be included under this classification when performed by iron or steel erection contractors who set in place the members to be welded.
