This “Statement of Special Inspections Guide” contains the interpretationsand opinions of the author and is intended to be a general guide forindividuals who are responsible for preparing the STATEMENT OF SPECALINSPECTIONS required by the International Building Code (IBC), section1704. This document is simply a guide and should not be consideredcomplete or be used as a stand-alone document that is incorporated into thecontract documents. A thorough review of the code requirements set forthby IBC and IBC reference codes and standards should be performed by theRegistered Design Professional in Responsible Charge prior to developinga project specific STATEMENT OF SPECIAL INSPECTIONS. The author of thisdocument is not liable or responsible for any errors or omissions that maybe found within this document.4Statement of Special Inspections Guide

General Special Inspection DefinitionsEssential FacilityThese are buildings that are considered to be essential in that their continuous useis needed, particularly in response to disasters. The phrase “designated as essentialfacilities” refers to designation by the building official that certain facilities arerequired for emergency response or disaster recovery. IBC Chapter 16, Table 1604.5“Risk Category of Buildings and Other Structures”, category IV lists some buildingtypes deemed essential facilities.Structural ObservationsThe visual observation of the structural system by a registered design professionalfor general conformance to the approved construction documents. Structuralobservations are not special inspections. (Definition is located in chapter 2 of the IBCcode book)Special InspectionsInspection and testing of construction requiring the expertise of an approved specialinspector in order to ensure compliance with this code (IBC) and the approvedconstruction documents. (Definition is located in chapter 2 of the IBC code book)Continuous Special InspectionSpecial inspection by the special inspector who is present when and where the workto be inspected is being performed or installed. (Definition is located in chapter 2 ofthe IBC code book)Periodic Special InspectionSpecial inspection by the special inspector who is intermittently present where thework to be inspected has been or is being performed or installed. (Definition is locatedin chapter 2 of the IBC code book)ObserveObserve these items on a random basis. Operations need not be delayed pendingthese inspections. (Definition is located in AISC 360, Chapter N, Section N5, #4)PerformPerform these tasks for each welded joint or member. (Definition is located in AISC360, Chapter N, and Section N5, #4)5
