Chapter 1 Special Inspections Program
CHAPTER 1 SPECIAL INSPECTIONS PROGRAM
SICC-101.1 Special inspections required. Effect March 1st 2007, the North Carolina Building Code Council revised section 1704.1 of the NC State Building Code. The revision implements a mandatory statewide program of special inspections. The Catawba County Special Inspections Program was established in response to this mandatory rule. The Special Inspections Program generally encompasses commercial buildings that are designated as essential facilities and buildings that represent a substantial hazard to human life in the event of failure. The Special Inspections Program is administered and monitored by the Catawba County Building Services Division.
SICC-101.2 Content. This document, Special Inspections Program (SICC-2007 ), implements the requirements of 2006 NCSBC Chapter 17. The SICC includes excerpts of technical requirements of the NCSBC and reference standards, policies and procedures underpinning the Special Inspections Program in Catawba County, and descriptions of the roles and responsibilities of all parties involved in special inspections. The SICC also includes excerpts from the “Guide to Special Inspections and Quality Assurance” developed by the Council of American Structural Engineers. This document is to be used in conjunction with the 2006 North Carolina State Building Code.
SICC-101.3 Special inspections and materials testing. The Special Inspections Program is based on the engineering and industry standards adopted by the North Carolina Building Code Council as a part of the NCSBC. These standards are promulgated by nationally recognized organizations such as the American Iron and Steel Institute (AISI); the American Institute of Steel Construction (AISC); the Portland Cement Association (PCA); the National Concrete Masonry Association (NCMA); the American Concrete Institute (ACI); and the Brick Industry Association (BIA). The requirements for special inspections and materials testing contained in the NCSBC (2006) and these standards can be categorized as follows:
Inspections and testing to substantiate adequacy of the fabrication process, e.g., quality of pre-manufactured steel beams.
Inspections and testing to substantiate adequacy of construction materials and their installation, e.g., strength of cast-in-place concrete.
Inspections and testing to substantiate adequacy of site construction techniques, e.g., protection of concrete during cold weather periods, quality of field welding of structural connections, etc.
The above standards do not specify who should perform special inspections. The NCSBC specifies that the owner is responsible to provide a firm independent of the contractor to provide required testing and inspections. Benefits to this method of inspection include:
Scheduling flexibility and minimizes delays during the construction process. A contractor does not have to wait for County inspectors to proceed with each stage of the special inspection process (These inspections are in addition to the inspections specified in the 2006 North Carolina Administrative Code & Policies Section 107. See Appendix C).
With the increased level of inspection services provided by a licensed professional, compliance with material specifications, quality control and workmanship and are improved.
