A brief account on the development of 3D models The trend of developing 3D models is not that old in the landscapes of AEC industry when it comes to optimizing them for building construction. Much before BIM came into picture, 3D CAD models were used by AEC professionals to represent the design of distinguished building systems such as architecture, structure and MEP. But limited information is derived by construction professionals from 3D CAD models which kind of restricted them from effective utilizations of these models for constructing the building. But once Building Information Modeling made its appearance in the landscapes of Architecture Engineering and Construction industry, construction industry professionals managed to get all kinds of necessary information.
BIM models gave new dimension to architects, engineers, contractors and building owners to extract information such as time and cost involved for accomplishing the
building. Exact calculation of time and money needed for the project, helped owners in enhancing the productivity of the project. In other words 4D and 5D BIM models proved to be extremely helpful for owners since they enabled them to estimate exact time and cost of the project. This eventually helped them in optimizing that information for increasing project productivity. For the development of BIM models it is important for any service providing company to have multitalented staff. That highly skilled BIM modelers are required who are highly proficient in handling high tech modeling software. In short their knowledge regarding software applications is very crucial when it comes to accurately using its distinctive tools and features. Another most significant thing for developing 3D models is the use of right software by the service providing company. Choosing the best modeling software is highly crucial and mostly Revit is used for this purpose by AEC professionals. While developing 3D models an entire team of BIM modelers is required and what remains important is their collaboration with each other for generating effective model. Accurate models can only be developed when the information required for generating them is successfully shared between the entire team. Accessibility of information helps in clearing the doubts of design development team and finally in developing productive and effective models.
