This doctoral thesis aims the theoretical and exploratory study of methodologies and mechanisms for automating 4D modeling,
applied in the processes planning of volumetric construction in steel. We assume that in architecture, planning is the link of
cohesion between design and construction. Hypothetically, we propose that through the study of methodologies and planning
tools, we could get to know the mechanisms to extend the digitized information at rendering the design of the building, organizing
it, in such a way that will be operable even in its industrialized production.
In the area of visual communication in architecture and design, we have noticed a growing interest by the use of these
innovations, the transition from CAD to BIM platforms, as well as the implementation of the CAVT (Computer Advanced
Visualization Tools), whence 4D technology originated. We find particularly motivating for the realization of this work, the
updating in 3D, 4D (3D + time) modeling techniques and its multidimensional progression; besides the verification of the
possibilities of integration and synchronization of information, through built-in mechanisms of these new tools. From them, we
draw general objective, know and describe how to prepare dynamic animation of assembly movements, a means of
representation and communication almost absent in architecture and construction.
In the exploratory proposal of the thesis we suggests, if in a 4D dynamic simulation model, ensures that the movements, and in
general, the parametrized behavior of 3D graphic entities, occur in accordance with the logic of the construction sequence, then,
the information used to represent the design of a building, would be used also for represent the construction process and develop
the virtual environment of planning, where movements would be displayed upon executing the operations, the strategy evaluated
and the length of its construction quantified.
With this work, we intend to overcome the characteristic use of animation in the representation of the design; witch in part has
caused the production of static images, preventing the virtual and dynamic representation of the construction processes. Then,
on the basis of the analyzed fundamentals, we explore and disclose how to develop a 4D model ¿as built¿, detailing the 3D
graphical entities that represent the integral parts of the objects of the building, and even the resources required to build them.
Subsequently, we describe how linked together with the construction operations, in an exercise known as process modeling.
Mainly we propose a strategy for the elaboration of the two virtual environments of the volumetric construction in steel, through
the respective models of dynamic simulation 4D, where the assembly operations in site and offsite production of a modular
building come alive virtually. To carry it out, we justify the integration of mechanical design platform, 4D and BIM, (Inventor,
Navisworks, and Revit) from Autodesk.
In the application of the thesis, we will approach to achieve integration of information from design and construction, for digitizing
the complete cycle of industrial production of a modular building. We provide a series of procedures, recommendations, and
qualitative appreciations, to capture and manage, the know-how of the logic of construction.
Keywords: 4D technology, visual simulation, process planning, virtual construction.
