Obayashi Corporation (大林組)

Obayashi offers an advance fire safety study service. It uses Route C, the advanced evacuation safety verification method, to obtain ministerial approvals (大臣認定) that already allow for future partition changes, which can relax high-rise compartmentation and reduce smoke-exhaust airflow. With Kokuyo it developed a multi-pane glass partition approved as a 10-minute fire-protective equipment (10分間防火設備), MLIT approval EBN010-0001, for use with evacuation safety verification.
