Established in 1955, CBGA has developed into a professional organization specializing in the building sciences with a unique dimension: a firm providing technical consulting related to Forensic Architecture – the professional analysis of buildings, spaces, and other built environments with regard to design, code, construction or material deficiencies to be used in a court of law or similar forums. Although a large percentage of our work relates to the analysis and correction of problems with existing construction, we are still an architectural firm, and we frequently take on new construction projects. Beginning in 1971, a unique aspect of our firm's practice has been in the forensic investigation of construction defects. Building owners, architects, contractors, subcontractors, and attorneys have retained CBGA for our expertise. We consider ourselves to be a highly specialized firm, specifically dealing with the technical aspects of problems in construction. The result is the generation of information reports, expert testimony, construction documents, implementation plans and details, peer review of construction documents, diagnosis, and prevention of significant malfunctions, defects, and failures for all aspects of construction planning, design, execution, and usage. Our organization is one of registered architects and building renovation experts who hold memberships in the American Institute of Architects (AIA), The American Association for Wind Engineering (AAWE), American Society for Testing and Materials (ASTM International), Construction Specifications Institute (CSI), The International Institute of Building Enclosure Consultants (IIBEC), and various other professional groups. We have been accepted by federal and circuit court systems as experts in the field of building, waterproofing and roofing technology and have served as consultants to leading architectural firms, general contractors, law firms, insurance companies and municipalities throughout the United States. Additionally, we have done extensive architectural and forensic investigative work for the U.S. Air Force, County governments and local school boards.
