There is no theory of production in construction’ (Koskela). This statement lies at the root of a growing thrust of research in construction project management called ‘Lean Construction’. Lean construction views construction as a continuous flow of activities and materials rather than as an aggregation of sharply distinguished activities, related only by technical and resource dependencies. The process of building design should also be considered in terms of flow, as information flows from task to task and actor to actor. The assumption is that he ‘workflow’ of design and construction, both in general and in specific project situations, can be engineered to provide better results than are currently common.
Parametric 3D modeling has the potential to replace the age-old paradigm of 2D drawings as the main medium of design, communication and information storage for construction in civil engineering (Eastman et al. 2003a). This research proposes to examine the economic impact of this shift.
