This document was developed by representatives of Building Officials and Code Administrators International, Inc. (BOCA), the International Conference of Building Officials (ICBO), the Southern Building Code Congress International (SBCCI) and representatives of the industry. The purpose of the Final Draft of the International Existing Building Code is to present material to generate public comment in the form of code change proposals to be processed by the IEBC Code Development Committee and ultimately voted upon by the membership of BOCA, ICBO and SBCCI. Development The technical committee charged with the task of developing the draft of the IEBC was formed by the International Code Council (ICC). The intent of the technical committee was to develop a draft of a comprehensive existing building code that is consistent with the family of International Codes already published. The technical content of currently published codes on existing buildings were reviewed and considered by the IEBC drafting committee. While there were many similarities among the documents reviewed, there were marked philosophical differences that were considered carefully by the drafting committee. The drafting committee used the same principles that were used to develop other International Codes. The principles were based on the intent to establish provisions consistent with the scope of an existing building code that adequately protects public health, safety and welfare;provisions that do not necessarily increase construction costs; provisions that do not restrict the use of new materials,products or methods of construction; and provisions that do not give preferential treatment to particular types or classes of materials, products or methods of construction, while at the same time encouraging the use and re-use of existing buildings. Coordination with other family of International Codes The incorporation of all regulations in a comprehensive document such as the IEBC necessitates an extensive coordination with other International Codes that contain provisions for existing buildings. Extensive provisions related to existing buildings are found primarily in the International Building Code® and International Fire Code®. The IEBC drafting committee, other volunteer industry representatives and staff will be developing a comprehensive code change package to be submitted to appropriate code development committees in an effort to coordinate the provisions of the IEBC with all other codes in the family of International Codes. Public Comment The meetings of the IEBC Drafting Committee have been open to the public and interested individuals and organizations from across the country participated. A public forum was also held in Portland, Oregon on March 24, 2001 during the ICC Code Development Hearings and the comments received were considered in the development of this Final Draft. • • Code Change Proposals The current opportunity for public comment is provided by means of code change proposals to be submitted by November 15, 2001. Please use the code change proposal form included in this document to submit your changes. The submitted proposals will be processed in the 2002 ICC Code Development Cycle. 2002 Code Change Cycle Proposed Code Changes for the 2002 Code Development Cycle are due November 15, 2001 Starting with the 2002 Code Development Cycle, ALL code changes are to be sent directly to ICC at: International Code Council, Inc. 5203 Leesburg Pike, Suite 600 • Falls Church, VA 22041-3401 (703) 931-4533 www.inticode.org • • ��`(� v Office Use Only _-` Log No. Code Change No. max INTERNATIONAL ICC PROPOSED CODE CHANGE CODE COUNCIL' (SEE SUBMITTAL PROCEDURES ON REVERSE SIDE) Name: Jurisdiction/Company: Submitted on behalf of: Address: City, State,Zip: Telephone: Facsimile: Signature:* *I hereby grant the International Code Council the nonexclusive,royalty-free rights,including nonexclusive,royalty-free rights in copyright,in this proposal and I understand that I acquire no rights in any publication of the International Code Council in which this proposal in this or another similar analogous form is used.I hereby attest that I have the authority and I am empowered to grant this copyright release.
