Karagozian & Case (K&C) provides design engineering services to protect buildings and other facilities, and their occupants and functionality. Long-time established (1945) and having facilities outside the US - Canada and Australia - the firm is focused primarily on developing protective designs and devices for extreme load environments such as those associated with blast, shock, and high-velocity impacts, K&C personnel also provide risk assessments and R&D related to blast effects and high-energy impacts. Objective: to ensure client security from risks associated with extreme events, especially malevolent threats such as those related to terrorist attacks that could involve blasts, high-velocity fragments and projectiles, and impacts from vehicles, ships, and airplanes. The firm provides the complete package of engineering design services, construction drawings and supervision, testing to demonstrate the validity of designs, and educational seminars to explain the technology behind the work. Provided protective designs fornew and existing buildings and of other types of facilities (e.g., sports arenas), bridges and other components of the infrastructure (e.g., dams, locks), and processing and manufacturing facilities (e.g., petrochemical plants). This encompasses protection for structural, mechanical, and electrical systems, including structural components such as steel and reinforced concrete columns and girders; piping and processing equipment; electrical devices; and walls and glazing facades. A number of unique and novel protective devices and design strategies have been invented, and have been instrumental in developing design tools and guides, and in advancing the state-of-the-art through our research and development activities and blast and impacts testing.
