Abstract

Prototype is a valuable resource to the product development process (PDP)
because it allows improvements on both knowledge about and performance of the product,
as well as the reliability on the product and processes related to its development and
production processes. Particularly in the built environment industry, the development of
physical prototypes has some inherent restrictions due to the uniqueness of its product. It
is understood that physical prototyping focused on the typical unit from residential projects,
currently used for solving design conflicts, can be more effective for improving production
processes in the construction site since those inconsistencies, which are the current focus,
are mitigated by the incorporation of virtual prototyping to the PDP of the constructed
environment. This practice is currently feasible due to the availability of tools that enable BIM.
The objective of this paper is to discuss the capability of focused physical, virtual analytical
and analytical representative prototypes for the identification of design inconsistencies. This
discussion is based on the results of an exploratory study, developed in a building company,
for which three different teams tackled the three different prototypes. Some criteria for
effectiveness assessment were also defined. The results show the benefits from BIM in terms
of effectiveness, costs and time.
