||"This paper presents the results of research about the impact of Computer Advanced Visualization Tools (CAVT) in the AEC project development process, carried out during PhD studies of the first author.CAVT are identified as core IT tools and defined in a broad sense, which involve their main feature of provide the ability to visualize the ends (Product models) and means (Process models) for AEC design and construction project development processes, focused in design and construction stages at the operational level.The impact of CAVT include three main dimensions: 1. The first related with the computational “science” aspect, explores how available comercial hardware and software has reached an adequate level of powerful, affordability and ease of use which will allow for a masive application of these tools in the AEC industry in the nearly future. Future demands in hardware and specially software developments are identified, and ways of lead them to the computer (software) industry are also presented.2. The second dimension of the impact explores how the evolution of Product and Process modeling has played a key role to support with knowledge for the practical application of commercial CAVT and how these two topics must be revisited when studied from a point of view, coming from CAVT widely application to a real life project.3. The third dimension is related with the actual organizatonal structures supporting design and construction processes development. Here is first demonstrated that actual organizational structures constitute an obstacle for CAVT efficient application, and a completely new organizational structure is needed is order to realize the real impact and take truly advantage of CAVT. An hipotetical organizational structure with high levels of integration and coordination, is then outlined, which need to be tested with further research in real life projects application.The research has an important therotetical background coming from analysis, study and contact with experts in ITC. This theoretical background has however been complemented with the study of CAVT application to a real life project, which has provided with decisive insights. The project has been designed, by first time in Latin America, completely in 3D using PDS software, a powerful Plant Design System provided by Intergraph, Inc. DesignReview software (also from Intergraph) has provided with powerful capabilties for the visualization of the product PDS 3D model. 4D modeling technology has been applied succesfully to the planning and scheduling tasks of the project to simulate the construction process, and has also provided with some important issues about how to improve the design. The study of the impact of CAVT shows that the ability to visualize the digital reality made up of a product model, and that visualization of the construction process (i.e 4D model), stands for a large reduction of the efforts in simplifications and abstractions, which traditionally has formed part of the basic input-transformation-output model for the AEC project development process. Location of the digital reality out of the boudaries of simplifications and abstractions leads to the conclusion that AEC industry is facing and ontological change without precedents in its history driven by CAVT within the ITC context. This paper will describe a bit more in detail this ontologyc change wich is about to revolution completely the way AEC projects has been developed until now."
