| This is a discussion of metals other than carbon steel, which are used in buildings in a structural manner and some of the special considerations that need to be addressed when they are used. These metal structures may be designed by the building engineer of record or may be designed by an engineer working for a specialty subcontractor. In the later case there may be review required by the building engineer of record as well as confirmation that the specialty architectural system details conform to assumptions of engineer of record in their design. |
