AMENDMENTS TO THE BULDNG CODE FOR THE CTY AND COUNTY OF DENVER
ACKNOWLEDGEMENT The review of the nternational Codes developed by the nternational Code Council (CC) was performed in response to concerns expressed on behalf of the construction and development industries, businesses, design professionals, educational institutions, local government, affordable housing and most of all the citizens of Denver. The CC Codes and the National Fire Protection Association (NFPA) Codes are written to meet the needs of a variety of jurisdictions and need to be fine-tuned to address the specific needs of the City and County of Denver. As a result, the Building Code Revision Committee (BCRC), a group of highly qualified individuals who have demonstrated knowledge and competence in the design and construction of buildings and structures developed these amendments. These individuals participated in the testing of building components and systems, the investigation of fires and explosions and in the enforcement of regulations pertaining to life-safety issues from fires, explosions and other hazards encountered in buildings and structures. This committee went through this process to recommend the adoption of the 2006 Series of -Codes. The committee members have produced a comprehensive set of effective amendments that directly affect safety to life within the City and County of Denver. As a result, these Amendments to the 2006 nternational Building Code and nternational Fire Code were adopted. We wish to acknowledge the members of Denver s City Council, the Mayor s Office, City Attorney s Office, Fire Department, Building and Construction Services of Community Planning and Development, the Building Code Revision Committee, its subcommittees and the organizations they represented for the time, dedication and professionalism devoted to the development of this document.
