CHAPTER 16 ARCHITECTURAL, MECHANICAL, ELECTRICAL COMPONENTS
For buildings assigned to Seismic Design Category C, D, E, or F, architectural, mechanical, electrical and plumbing components shall have a quality assurance plan, and be specially inspected and tested, in accordance with NCSBC-1705.1, NCSBC-1707.1, 1707.6, 1707.7, NCSBC-1708.2, and 1708.5.
NCSBC-1705.1 Scope. A quality assurance plan for seismic requirements shall be provided in accordance with Section 1705.2 for the following:
Designated seismic systems in structures assigned to Seismic Design Category D, E, or F.
The following additional systems in structures assigned to Seismic Design Category C:
HVAC ductwork containing hazardous materials, and anchorage of such ductwork
Piping systems and mechanical units containing flammable, combustible or highly toxic materials
Anchorage of electrical equipment used for emergency or standby power systems.
The following additional systems in structures assigned to Seismic Design Category D:
Systems required for Seismic Design Category C.
Exterior Wall panels and their anchorage.
Suspended Ceiling systems and their anchorage.
Access Floors and their anchorage.
Steel storage racks & anchorage, where the factor Ip, determined in Section 22.214.171.124 of ASCE 7, is equal to 1.5.
A QA plan is not required for structures designed and constructed in accordance with the conventional construction provisions of Section 2308.
A QA plan is not required for structures constructed of light wood framing or light framed cold-formed steel; the SDS as determined in Section 1615.1 does not exceed 0.5g, and the height of the structure does not exceed 35 feet above grade plane.
A QA plan is not required if the structure is constructed using a reinforced masonry structural system or reinforced concrete structural system; the SDS as determined in Section 1615.1 does not exceed 0.5g, and the height of the structure does not exceed 25 feet above grade plane.
SICC-1602 INSPECTIONS AND TESTS
NCSBC-1707.1 Special inspections for seismic resistance. Special inspection as specified in this section is required for the following, where required in Section 1704.1. Special inspections itemized in Sections 1707.2 through 1707.8 are required for the following: 3. Architectural, mechanical and electrical components in structures assigned to Seismic Design Category
C, D, E or F that are required in Sections 1707.5, 1707.6 and 1707.7.
NCSBC-1707.5 Storage racks and access floors. Periodic special inspection during the anchorage of access floors & storage racks 8 feet or greater in height in structures assigned to Seismic Design Category D, E, or F.
NCSBC-1707.6 Architectural components. Periodic Special insepction during the erection and fastening of exterior cladding, interior and exterior nonbearing walls and interior and exterior veneer in structures assigned to Seismic Design Catergory D, E, or F. Exceptions:
1. Special inspection is not required for architectural components in structures 30 feet or less in height.
Special inspection is not required for cladding and veneer weighing 5 psf or less.
Special inspection is not required for interior nonbearing walls weighing 15 psf or less.
NCSBC-1707.7 Mechanical and electrical components. Periodic special inspection during the anchorage of Page 60
