A design notification scheme for distributed AEC framework
Abstract: The Architecture, Engineering and Construction design process (AEC)
involves participation of many inter-dependent specialists, who nevertheless
make autonomous design decisions in their specialized domains. This
fragmented and multidisciplinary design process often suffers from inadequate
communication among specialists and a lack of coordination of design
information. In this paper, we present a design-change notification scheme
for a distributed engineering environment. The notification scheme facilitates
conflict resolution by providing the relevant information about the design
objects involved in a conflict. It operates on a global design repository, which
uniformly captures the design data and cross-functional design dependencies.
Upon detection of a design conflict, notification messages are automatically
generated and delivered to concerned project participants in a particular
sequence that is based on the nature of the conflict and the roles of the
parties involved. We assert that this type of notification system in a design
environment will facilitate identification of design conflicts early in the design
process, and should decrease the number of change orders and rework during
the construction phase. Fewer change orders and reduced project meetings
can result in enhanced trust, improved cooperation, and lower project costs.
