SICC-1401 GENERAL

SICC-1401.1 Scope. The requirements of this chapter and NCSBC-1704.12 shall apply when construction includes exterior insulation and finish systems (EIFS) elements as listed in SICC-302.9.

NCSBC-1704.12 Exterior insulation and finish systems (EIFS). Special inspections shall be required for all EIFS applications.

Exceptions:

  • 1.

    Special inspections shall not be required for EIFS applications installed over a water-resistive barrier with a means of draining moisture to the exterior.

  • 2.

    Special inspections shall not be required for EIFS applications installed over masonry or concrete walls.

SICC-1402 FABRICATION AND ERECTION DOCUMENTS

SICC-1402.1 Review and approval. The GC shall submit two sets of EIFS fabrication and erection documents to AR and SER for review and approval prior to EIFS elements' fabrication, erection or application, as appropriate. The AR and the SER shall review and approve the fabrication and erection documents for compliance with the architectural and structural design of the building and the County approved construction documents.

SICC-1402.2 Preparation of fabrication and erection documents. The RDP responsible for preparation of the EIFS construction documents shall also prepare, sign and seal the EIFS fabrication and erection documents. Information shall include, but not be limited to:

  • Copy of EIFS research report and identification of EIFS manufacturer.

  • EIFS manufacturer installation and application instructions.

  • Layout and details for application of insulation boards.

  • Location, configuration & details for control joints, flashing, weepholes, sealants and caulking.

  • System installation criteria, including ambient temperature limitations.

  • Criteria and timing for special inspections during construction.

  • Design wind pressure on the EIFS and related calculations.

  • Waterproofing and drainage provisions including weepholes and any limitations on EIFS or building materials, especially substrate and building framing, for prevention of moisture infiltration to building sheathing or framing.

  • EIFS material types and thicknesses, including flame spread and smoke development ratings.

  • Details consistent with intent of the research report and manufacturer’s instructions for method of installation at all openings, corners and panel terminations.

  • Typical cross-sectional configuration showing all components of the wall. All building sheathing and framing materials in contact with the EIFS shall be dampproofed in accordance with NCSBC-1806. Wood shall also be naturally durable or preservative-treated in accordance with NCSBC-2303.1.8.
