As cities have expanded, they have become more vulnerable to disasters due to their reliance
on highly engineered environments and the interdependency among infrastructure systems
such as energy and transportation. In addition, it is expected that we will encounter disasters
more frequently and that they will be more severe. Nevertheless, the triad of first responders
including firefighters, police, and emergency medical service may bring about an
inappropriate response picture; i.e., independently assembled command centers and
resources; great difficulties in processing information, communication, and coordination; and
inadequate roles for civil engineers.
Part of the problem has been identified as associated with their need to have high
‘Situation Awareness’. In order to effectively meet work demand in distributed, dynamic,
and chaotic conditions, first responders need high situation awareness; however, this need is
unfulfilled in most cases due to their inability to access information, limitations of IT
technology, and organizational problems [McKinsey&Company, 2002].
In this study, we explore a response framework into which civil engineers and IT
components are integrated to help grasp the relation between situation awareness,
collaboration, and performance. Then, the framework is embodied in a casual loop diagram
to represent the disaster dynamics. As a result, it is expected that the situation awareness will
have a positive relation with communication and coordination between response
organizations and their performance. It is also expected that technical support of civil
engineers and employment of new IT components would make a critical contribution to
increasing situation awareness. These results will support the vision that in future disaster
response scenarios involving urban areas, civil engineers could and should play a role as a
fourth key disaster responder. In addition, it is expected that the support of civil engineers
and IT components can increase the performance of responders by facilitating collaboration
between responders through improvement of situation awareness.
