A software architecture for self-updating life-cycle building models

This paper describes a computational infrastructure for the realization Of a self-updating building information model conceived in the design phase and carried over to the operation phase of a building. As such, it illustrate how computational representations of buildings, which typically serve design support, documentation, and communication functions, can be transported into the post-construction phase. Toward this end, we formulate a number of requirements for the conception and maintenance of life-cycle building information models. Moreover, we describe the architecture and the prototypical implementation Of such a model.
