Chapter 16 Architectual, Mechanical & Electrical Components

electrical equipment for emergency or standby power systems in structures assigned to Seismic Design Category C, D, E or F. Periodic special inspection during the installation of anchorage of other electrical equipment in structures assigned to Seismic Design Category E or F. Periodic special inspection during installation of piping systems intended to carry flammable, combustible, or highly toxic contents and their associated mechanical units in structures assigned to Seismic Design Category C, D, E or F. Periodic special inspection during the installation of HVAC ductwork that will contain hazardous materials in structures assigned to Seismic Design Category C, D, E or F.

NCSBC-1707.7.1 Component inspection. Special inspection is required for the installation of the following components where the component has a Component Importance Factor of 1.0 or 1.5 in accordance with Section 9.6.1.5 of ASCE 7.

  • 1.

    Equipment using combustible energy sources.

  • 2.

    Electrical motors, transformers, switchgear unit substations and motor control centers.

  • 3.

    Reciprocating and rotating-type machinery.

  • 4.

    Piping distribution systems 3 inches (76 mm) and larger.

  • 5.

    Tanks, heat exchangers and pressure vessels.

NCSBC-1707.7.2 Component and attachment testing. The component manufacturer shall test or analyze the component and the component mounting system or anchorage for the design forces in Chapter 16 for those components having a Component Importance Factor of 1.0 or 1.5 in accordance with Chapter 16. The manufacturer shall submit a certificate of compliance for review and acceptance by the registered design professional responsible for the design, and for approval by the building official. The basis of cer- tification shall be by test on a shaking table, by three-dimensional shock tests, by an analytical method using dynamic characteristics and forces from Chapter 16 or by more rigorous analysis. The special inspector shall inspect the component and verify that the label, anchorage or mounting conforms to the certificate of compliance.

NCSBC-1707.7.3 Component manufacturer certification. Each manufacturer of equipment to be placed in a building assigned to Seismic Design Categories E and F, in accordance with Chapter 16, where the equipment has a Component Importance Factor of 1.0 or 1.5 in accordance with Chapter 16, shall maintain an approved quality control program. Evidence of the quality control program shall be permanently identified on each piece of equipment by a label.

NCSBC-1708.2 Testing for seismic resistance. The tests specified in Sections 1708.3 through 1708.6 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 Section 1708.5.

NCSBC-1708.5 Mechanical and electrical equipment. Each manufacturer of designated seismic system components shall test or analyze the component and its mounting system or anchorage and shall submit a certificate of compliance for review and acceptance by the registered design professional in responsible charge of the design of the designated seismic system and for approval by the building official. The evidence of compliance shall be by actual test on a shake table, by three-dimensional shock tests, by an analytical method using dynamic characteristics and forces, by the use of experience data (i.e., historical data demonstrating acceptable seismic performance), or by more rigorous analysis providing for equivalent safety. The special inspector shall examine the designated seismic system and shall determine whether the anchorages and label conform with the evidence of compliance.

SICC-1603 COMPLETION OF ARCHITECTURAL, MECHANICAL AND ELECTRICAL COMPONENTS

Upon completion, the SIER shall submit a completion letter to CCBSD. The SIER shall also indicate the date of completion on the final report of special inspections for architectural, mechanical, and electrical components.
