PURPOSE The provisions for Special Inspections are intended to provide a higher degree of scrutiny for aspects of construction that, upon failure, would cause significant harm. These aspects of construction include certain soil suitability, fabrication and installation of structural steel members, cold-formed steel members and decking, certain concrete and masonry construction, fabrication and installation of certain wood structural elements, pile and pier foundations, sprayed fire-resistant materials, wall panels and veneer systems, EIFS, smoke control systems and special cases as detailed in the Construction Code. These are spelled out in Section 1705 of the Construction Code and this manual. The International Building Code (IBC), as adopted by reference through the Construction Code, intends that a qualified professional be in responsible charge of the inspection of these specialty types of construction. The Special Inspection program is intended to safeguard public safety and general welfare through specialized verification of structural, fire and critical component integrity of building materials. Background Numerous avoidable structural failures occurred during the late 1970s and early 1980s throughout the United States. These failures resulted in personal tragedies and tremendous property damage costs. However, most if not all of these failures were predictable in nature and centered on one common theme: lack of an adequate construction inspection process. In August 1982, the U.S. House of Representatives Subcommittee on Investigations and Oversight, chaired by Albert Gore, Jr., held investigative hearings to examine the causes of structural failures. This subcommittee was part of the Committee on Science and Technology. In March 1984, the Committee on Science and Technology’s report titled Structural Failures in Public Facilities, House Report 98-621, was presented to the 98th Congress. The following are highlights from this report. The central issue addressed by the Subcommittee was “Are there common problems associated with structural failures, the elimination of which would decrease the number of failures?” While the Subcommittee identified over 20 contributing factors, two common problems were felt to be the most critical: • 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. The Subcommittee found that: “For a variety of reasons, the Structural Engineer of Record or his designee is often not present on the job site during the construction Special Inspection Policy Manual Effective October 1, 2022; Revised April 14, 2022 Page 6 of 46 of principal structural components. The absence of the Structural Engineer has permitted flaws and changes on site to go unnoticed and uncorrected.” The Subcommittee recommended that: “Professional organizations, such as the Building Officials and Code Administrators International, the International Conference and Building Officials, and the Southern Building Code Conference International, 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.” That precipitated the drafting of Chapter 17 in the International Building Code. Application and enforcement were essential to the success of the program. To accomplish this goal, the Washington, D.C. building safety community has joined together to formulate a uniform set of procedures for the manner in which DOB enforces Special Inspection provisions of the Construction Code. This includes the standard for experience and qualifications necessary to adequately control the work being performed, duties of the Special Inspections Engineer of Record and other parties, reporting requirements, as well as oversight by the jurisdiction. It specifies the type and manner of work, how it is to be performed, and any supervision required. It also clarifies the requirements for reporting the results and recordkeeping. The provisions for Special Inspections are intended to provide a higher degree of expertise in the implementation of the structural design for critical aspects of building construction not normally found in the local building department. Overview Special Inspections is the monitoring of certain materials critical to the integrity of the building structure. It is a specialized inspection of certain, complex construction work of the contractors and their employees to help ensure that the approved plans and specifications are being followed and that the relevant codes and referenced standards are being followed. The special inspection process is in addition to the inspections conducted by the Chief Building Official and continuous or periodic observation by the Special Inspections Engineer of Record. The DOB Special Inspection Policy (SIP) Manual provides and coordinates the procedures for Special Inspections that are required by the DOB-amended IBC. These procedures and guidelines are expected to be used during the design and permitting process and during construction. Special Inspection Policy Manual Effective October 1, 2022; Revised April 14, 2022 Page 7 of 46 The DOB Special Inspection Policy Manual includes the following: • The responsibilities of the Registered Design Professional responsible for the structural design. • The role of each member of the building construction team to include the Registered Design Professionals, Building Owner, Contractors, the Special Inspections Engineer of Record (SIERs) and Agents, Architect of Record, Geotechnical Engineer of record, and Chief Building Official, DOB and Third- Party Inspections personnel whose role is defined in the DOB Third-Party Program Procedural Manual. • The experience and qualifications necessary to supervise and perform Special Inspections. • Procedures and standards to regulate who may perform Special Inspections. • Identification of the required areas of Special Inspections. • Administrative procedures that include a standardized Statement of Special Inspection form and a Final report of Special Inspection form that is accepted by DOB, important definitions, reporting requirements, and conflict resolution procedures. The purpose of the DOB Special Inspections Policy Manual is to increase awareness of the Special Inspection requirements and to have a uniform procedure applicable throughout the District. In addition, the Manual should help reduce the problems associated with authorizing and performing Special Inspections. The following steps describe the process of conducting and reporting Special Inspections: • During the design phase, the Registered Design Professional in Responsible Charge (RDPRC) and Structural Engineer of Record (SER) identify construction elements or materials that must be specially inspected. A Schedule of Special Inspections must be noted on the construction documents in or near the front of the plan set near the building code analysis. The Chief Building Official will review the Schedule of Special Inspections for accuracy and inclusion of all elements subject to special inspection. Additionally, the RDPRC must notify the owner of the required Special Inspections. • The Owner selects a Special Inspections Engineer of Record from the DOB- approved list for the category of construction. • The SIER must complete a Statement of Special Inspections (using the form), have all the required parties sign the document indicating an understanding of what is expected of them, and submit this form to DOB for review at the same time construction documents are uploaded in ProjectDox. • Prior to permit issuance and after the construction documents are approved by DOB, a pre-construction meeting will be held with the Special Inspections Engineer of Record presiding with certain required attendees and some invited members with an option to attend. Special Inspection Policy Manual Effective October 1, 2022; Revised April 14, 2022 Page 8 of 46 • The permit may be issued after DOB is assured that the pre-construction meeting was conducted. This is confirmed by the Special Inspections Engineer of Record submitting meeting documents to DOB and approved by DOB to include the meeting minutes, contact sheet, statement of special inspections, schedule of special inspections, acknowledgement form, notification of intent form, special inspections subcontractor’s list form. • Construction may begin. The contractor must abide by the schedule of required special inspections and allow the Special Inspections Engineer of Record to conduct all required special inspections prior to concealment or the subsequent construction. The contractor must maintain all special inspection documents including interim field reports for DOB or the Third-Party Inspector’s review. The Contractor will maintain a DOB template for an on-site activity/incident log for all special inspection work. This shall be maintained for the DOB Inspector and Third- Party Inspector’s review. • The SIER must notify the RDPRC and SER of any changes to the design affecting the schedule of special inspections. • The SIER has specific duties. When each special inspection report is either approved with no exceptions taken or with the deficiencies noted, this must be noted on the interim reports and on the activity/incident log for DOB and the Third-Party Inspector’s review at an appropriate phase of construction. Where work is concealed by the contractor without meeting the special inspection requirement or the Special Inspections Engineer of Record deems it necessary to stop construction to ensure the quality of work, they must notify DOB, the Third-Party Inspection Agency, and the Registered Design Professional in Charge. If necessary, DOB will post a Stop Work Order to ensure the efficacy of the Special Inspections program. • When specified Special Inspection items are complete and non-compliance issues resolved, the Special Inspections Engineer of Record must complete the final report of special inspections (form) with acceptance by the RDPRC and/or SER and submitted to DOB for acceptance prior to any request for any building final inspection. • Record retention for special inspection activity is maintained by both the special inspection agency and DOB for the period set out by law. See the District of Columbia Records Retention Schedule. General Requirements The Special Inspections Program requirements outlined in this manual shall apply to the following structures and/or structural elements submitted in the Statement of the Special Inspection or when so required by the Chief Building Official.
