1 Gwinnett County Department of Planning & Development Special Inspections Program A. Building Code I. Authority, Scope and Purpose The 2006 International Building Code with Georgia amendments, currently in effect for the state of Georgia and hereafter referred to as the Building Code, requires special inspections during construction of buildings, structures, and building/structure additions, and renovation of existing structural systems and components. B. Projects That Require Special Inspections Special inspections are typically required for projects which require the practice of professional engineering or architecture as defined by the applicable state law governing the professional registration and certification of engineers or architects except for construction of minor scope or pertinent to one- and two-family residences. C. Purpose of Special Inspections This Special Inspections Program establishes the provisions for inspecting components of construction in which strength, safety, and construction practices have a critical impact on the integrity of a building or structure as determined by the Building Code, engineer- and/or architect-of-record, and/or the Building Official or his/her designees including building inspectors and plan review staff. D. Scope of Special Inspections Special inspections consist of monitoring specific construction materials and workmanship of contractors and their employees to verify that construction is completed in accordance with the plans authorized for permit issuance, specifications, and relevant codes and ordinances. E. Basis for Gwinnett County Special Inspections Program This Special Inspections Program is based on the ACEC/SEAOG SI GL 01-03/2006, Georgia Special Inspections Guidelines, as authorized by section of the Building Code. F. Coordination with Other Inspections Required special inspections are in addition to those conducted by the Building Inspections Section and by the registered design professional in responsible charge as part of periodic structural observation.

2 Gwinnett County Department of Planning & Development Special Inspections Program G. Role and Qualifications of Special Inspectors Authorized special inspectors shall perform the continuous and periodic inspections required by this Special Inspections Program for each construction project to determine compliance of the construction materials and workmanship with the requirements of the construction documents authorized for permit issuance. Each special inspector shall satisfy the minimum qualifications established by Table of the Building Code. H. Authorization for Changes to Construction Documents Approval by the Design Professional In Responsible Charge, hereafter referred to as the DPIRC, is required for any deviations from or revisions to the documents authorized for issuance of a building permit. I. Summary of Key Steps Refer to Appendix D for a summary of the key steps associated with this Special Inspections Program. II. Plan Review/Permitting Requirements A. Determine Required Special Inspections The DPIRC determines the extent to which special inspections are required for each construction project per sections 1704, 1707 and 1708 of the Building Code. B. Documents Required Prior to Building Permit Issuance The DPIRC develops the Statement of Special Inspections (Appendix A, p. A1), Statement of Special Inspections Requirements for Seismic Resistance (Appendix A, p. A2), and Schedule of Special Inspection Services (Appendix B, pp. B1-B7) which are submitted to the Building Plan Review Section for review with the project construction documents prior to issuance of a building permit. C. Identify and Authorize Special Inspectors The owner or DPIRC submits a list of the individuals, agencies or firms intended to be retained for conducting special inspections including documentation to substantiate the qualifications of each individual inspector to the Building Plan Review Section prior to issuance of a building permit. Building Plan Review and Building Inspections staff jointly review the documentation to verify compliance with the minimum requirements of Table (Minimum Special Inspector Qualifications) of the Building Code and determine the scope of special inspections that each individual, agency, or firm is authorized to perform.
