Revise as follows:

1. Revise as follows:

1704.3.2 Seismic requirements in the statement of special inspections. Where Section 1705.11 or 1705.12 specifies special inspections, testing or qualification or tests for seismic resistance, the statement of special inspections shall identify the designated seismic systems and seismic force-resisting systems that are subject to the special inspections or tests.

1705.11.4 Designated seismic systems. The special inspector shall examine designated seismic systems requiring seismic qualification in accordance with Section 1705.12.3 13.2.2 of ASCE 7 and verify that the label, anchorage or and mounting conforms to the certificate of compliance.

1705.12 Testing and qualification for seismic resistance. The Testing and qualification for seismic resistance is required as specified in Sections 1705.12.1 through 1705.12.4 1705.12.5, unless exempted from special inspections by the exceptions of Section 1704.2, are required as follows:

(no other changes to this section are proposed)

1705.12.3 Seismic certification of Nonstructural components. For structures assigned to Seismic Design Category B, C, D, E or F, where the requirements of Section 13.2.1 of ASCE 7 for nonstructural components, supports or attachments are met by seismic qualification as specified in Item 2 therein, the registered design professional shall specify on the construction documents the requirements for certification seismic qualification by analysis, testing or experience data for nonstructural components and designated seismic systems in accordance with Section 13.2 of ASCE 7, where such certification is required by Section 1705.12. Certificates of compliance for the seismic qualification shall be submitted to the building official .

2. Add new text as follows:

1705.12.4 Designated seismic systems . For structures assigned to Seismic Design Category C, D, E or F and with designated seismic systems that are subject to the requirements of Section 13.2.2 of ASCE 7 for certification, the registered design professional shall specify on the construction documents the requirements to be met by analysis, testing or experience data as specified therein. Certificates of compliance documenting that the requirements are met shall be submitted to the building official .

(renumber remaining section)

Reason:

The provisions in Section 1705.12.3 are placed in two sections to provide effective charging language for the corresponding provisions in ASCE 7-10 for nonstructural components meeting special requirements and designated seismic systems, which differ substantially from each other. References to “certification” and “qualification” in this section as well as other sections in the proposal are also revised for consistency with the corresponding provisions of ASCE 7-10. Seismic qualification and certification are technical requirements that are covered by the provisions in ASCE 7-10 (Sections 13.2.1 and 13.2.2). What is relevant in the building code is the submittal of certificates of compliance (manufacturer’s certification in ASCE 7-10) to the building official for verification that the requirements for seismic qualification and certification are met and language is added to both sections for this purpose. The requirement to submit certificates of compliance to the building official is also added to both sections for consistency with corresponding language in ASCE 7-10. Items #1 and #2 in Section 13.2.2 of ASCE 7-10 both specify submittal “for approval to the authority having jurisdiction after review and acceptance by a registered design professional.” Item #1 in Section 13.2.1 of ASCE 7-10 contains similar language. Item #2 in Section 13.2.1, however, specifies submittal but not to whom. This has been judged to be an oversight on the part of the ASCE 7 Committee whose membership includes two members of the WABO Technical Code Development Committee. This has been brought to the attention of the ASCE 7 Committee and a proposal that addresses the issue will be submitted for consideration in the next development cycle for the standard. The current language in Section 1705.12.3 for the registered design professional to specify on the construction documents the requirements to be met by analysis, testing or experience data is not substantively changed by this proposal. Also in Section 1705.12.3, the scope is expanded to include structures assigned to Seismic Category B. For a nonstructural component in a structure where the option of seismic qualification by analysis, testing or experience data in Section 13.2.1, Item 2, of ASCE 7-10 is chosen, the requirements to document the parameters for seismic qualification on the construction documents and to submit the certificate of compliance for seismic qualification to the building official will apply. These requirements, however, are the consequence of the owner, design team or construction team choosing to comply with Section 13.2.1 of ASCE 7-10 through seismic qualification rather than the design option in Section 13.2.1, Item 1 of ASCE 7-10. Note that a separate proposal modifies the requirement in Sections 1705.12.3 and 1705.12.4 to submit certificates of compliance for consistency with the changes in that proposal by stating that they shall be submitted to the building official “as specified in Section 1704.5” (Sxx-12/13).

Cost Impact: The code change proposal will not increase the cost of construction.
