(Amended by Ord. No. 184,692, Eff. 12/30/16.)

91.1711.1. General.

91.1711.1.1. Purpose. The purpose of this section is to regulate materials and establish methods of safe construction where any structure or portion of the structure is wholly or partially prefabricated.

91.1711.1.2. Scope. (Amended by Ord. No. 185,587, Eff. 7/16/18.) Unless otherwise specifically stated in this section, all prefabricated construction and all materials used in the construction shall conform to all the requirements of this Code. (See LAMC Subdivision 91.104.2.6.)

91.1711.1.3. Definition. (Amended by Ord. No. 185,587, Eff. 7/16/18.)

PREFABRICATED ASSEMBLY. A structural unit, the integral parts of which have been built up or assembled prior to incorporation in the building.

91.1711.2. Tests of Materials. Every approval of a material not specifically mentioned in this Code shall incorporate as a proviso, the kind and number of tests to be made during prefabrication.

91.1711.3. Tests of Assemblies. The Superintendent of Building may require special tests to be made on assemblies to determine their durability and weather resistance.

91.1711.4. Connections. See CBC Section 1611.11.1 for design requirements of connections for prefabricated assemblies.

91.1711.5. Pipes and Conduits. See CBC Section 1611.11.2 for design requirements for removal of material for pipes, conduits and other equipment.

91.1711.6. Certificate and Inspection.

91.1711.6.1. Materials. Materials and the assembly of materials shall be inspected to determine compliance with this Code. Every material shall be graded, marked or labeled where required elsewhere in this Code.

91.1711.6.2. Certificate. A Certificate of Approval shall be furnished with every prefabricated assembly, except where the assembly is readily accessible to inspection at the site. The Certificate of Approval shall certify that the assembly in question has been inspected and meets all the requirements of this Code. When mechanical equipment is installed so that it cannot be inspected at the site, the Certificate of Approval shall certify that the equipment complies with all applicable laws and regulations.

91.1711.6.3. Certifying Agency. (Amended by Ord. No. 185,587, Eff. 7/16/18.) To be acceptable under this Code, every Certificate of Approval shall be made by an approved testing agency.

91.1711.6.4. Field Erection. Placement of prefabricated assemblies at the building site shall be inspected by the Department to determine compliance with this Code.

91.1711.6.5. Continuous Inspection. If continuous inspection is required for certain materials where construction takes place on the site, it shall also be required where the same materials are used in prefabricated construction.

EXCEPTION: Continuous inspection will not be required during prefabrication if the approved testing agency certifies to the construction and furnishes evidence of compliance. (Amended by Ord. No. 185,587, Eff. 7/16/18.)
