Chapter 8 Precast Concrete

CHAPTER 8 PRECAST CONCRETE

SICC-801 GENERAL

SICC-801.1 Scope. The requirements of this chapter, NCSBC-1704.4, and NCSBC-Table 1704.4 Item 9 shall apply when construction includes precast concrete building elements as listed in SICC-302.4.

SICC-801.2 Precast concrete fabrication. Fabricators for off-site precast concrete elements shall be subject to special inspections as required by SICC-302.1 and SICC-803 and NCSBC-1704.2. Site-cast precast concrete elements shall be subject to special inspections during fabrication as required by SICC- 2007 Chapter 7 and SICC-804.1, and NCSBC-1704.4.

SICC-801.3 Precast concrete erection. Precast concrete elements shall be subject to special inspections during erection as required by SICC-804.2 and NCSBC-Table 1704.4 Item 9.

SICC-802 FABRICATION AND ERECTION DOCUMENTS

SICC-802.1 Review and approval. The concrete mix designs shall be submitted to the RDP responsible for preparation of precast concrete designs and the AR, SER for review and approval. The fabrication and erection documents shall be submitted for review and approval to the SER prior to precast concrete elements' fabrication and/or erection, as appropriate. The GC shall provide SER-approved fabrication and erection documents, including the concrete mix designs for use by the SIER to conduct special inspections during construction.

SICC-802.2 Preparation of fabrication and erection documents. A RDP with experience in the design of precast concrete structures shall prepare sign and seal fabrication and erection documents for precast concrete building elements, including but not limited to: design drawings and calculations, connection details, design of lifting inserts, rigging requirements, and erection bracing. Documents for site-cast precast concrete shall also include, but are not limited to: element fabrication, form removal, storage and transportation.

SICC-802.3 AR and SER review and approval. The AR and the SER shall review the fabrication and erection documents and the concrete mix designs for compliance with the architectural and structural design of the building.

SICC-803 INSPECTION OF PRECAST CONCRETE FABRICATORS

Where fabrication of precast concrete elements is being performed off-site on the premises of a fabricator's shop, special inspection of the fabricator is required (see SICC-302.1 and NCSBC-1704.2). The SIER shall verify that the precast plant has a documented and implemented Quality Control Program and shall notify CCBSD in writing of his/her findings. The minimum quality control program shall be in accordance with the Precast/Prestressed Concrete Institute (PCI) Plant Certification Program. Alternatively, the SIER may inspect the precast plant at appropriate intervals to verify that materials, methods, products, and quality control comply with project specifications, RDP approved fabrication and erection documents. PCI MNL- 116, "Manual for Quality Control for Plants and Production of Precast and Prestressed Concrete Products," and/or PCI MNL-117, "Manual for Quality Control for Plants and Production of Architectural Precast Products" are resources available to the SIER for plant inspections.
