  • 3. WHAT IS AND WHY IS THERE A SPECIAL INSPECTION PROCESS? Special Inspections Versailles Wedding Hall Jerusalem, Israel Hyatt Regency Walkway Kansas City, Missouri
  • 4. 2012 IBC Chapter 2 Definitions: SPECIAL INSPECTION. Inspection of construction requiring the expertise of an approved special inspector in order to ensure compliance with this code and the approved construction documents. 2009 IBC Section 1702 Definitions: Special Inspection is the inspection of the materials, installation, fabrication, erection or placement of components and connections requiring special expertise to ensure compliance with approved construction documents and referenced standards. Special Inspections
  • 5. • Since the 1988 Supplement to the 1987 Edition of the BOCA National Codes, Special Inspections have been part of the building code. Special Inspection requirements have addressed three specific areas in the construction process: Special Inspections

  • 9. Numerous structural failures occurred during the late 70’s and early 1980’s, for example: Skyline Plaza Fairfax County, VA Collapse of a 26 story reinforced concrete residential tower Rosemont Horizon Arena Illinois Glued laminated timber roof arches spanning 288 feet collapsed The 1970’s Special Inspections
  • 10. Highway Ramp Collapse East Chicago, Indiana Temporary false work collapsed during construction. Harbour Cay Condominium Cocoa Beach, FL A five (5) story, cast-in-place reinforced concrete building collapsed due to design and construction deficiencies Numerous structural failures occurred during the late 70’s and early 80’s, for example: The 1980’s Special Inspections
  • 11. In 1982 the U.S. House of Representatives Subcommittee on Investigations and Oversight, chaired by Albert Gore, Jr., held investigative hearings regarding these structural failures. Special Inspections
  • 12. The Subcommittee identified over twenty contributing factors, with two of the most critical being: Special Inspections
  • 13. The Subcommittee identified over twenty contributing factors, with two of the most critical being: • The need for improved organization on construction projects and better communication between participants. Special Inspections
  • 14. The Subcommittee identified over twenty contributing factors, with two of the most critical being: • The need for improved organization on construction projects and better communication between participants. • The need for construction inspection by the Structural Engineer of Record (SER) during the construction of principal structural components. Special Inspections
  • 15. The Subcommittee recommended: “Professional organizations, such as the Building Officials and Code Administrators International (BOCA), the International Conference and Building Officials (ICBO), and the Southern Building Code Conference International (SBCCI), should make every effort to ensure that provisions are written into the building codes and adopted in public forum which make the on-site presence of the structural engineer mandatory during the construction of structural components on public facilities.” Special Inspections
  • 16. Model code organizations and Building Officials have attempted to address structural failures by enacting and enforcing Special Inspection provisions since the 1988 Supplement to the 1987 Edition of The BOCA National Building Code. • All forty-eight (48) states within the United States have adopted and/or amended the IBC. • Chapter 17 of the IBC currently mandates the Special Inspection requirements. Special Inspections
  • 17. However, the Special Inspection process and the role of the Structural Engineer of Record have been topics of controversy and confusion in recent years. • Many national engineering organizations, such as the ACEC and the Virginia Structural Engineers Council, as well as CASE, agree with the Subcommittee’s recommendations and believe strongly that the Structural Engineer of Record or his agent should serve as the Special Inspector whenever possible and practical. • Likewise, it seems the congressional committee reached the same conclusions.
