What are the principal advantages of using a single building information model of the existing conditions as the foundation for modeling proposed additions or renovations?
By consolidating multiple phases of infrastructure development into a single building information model, all of the information about the development can be accessed in one place. This makes it much easier for all interested parties to see all of the different aspects of the project. Additionally, it’s helpful to visualize the transformation from one building to another, as multiple phases can show the project of demolition. In this way, using one building information model is more efficient and informative than simply creating a new separate model for the proposed design.
What are the principal advantages of using a single building information model of the existing conditions as the foundation for modeling several proposed design alternatives for a portion of the building?
Similarly to the previous question, the use of a single building information model allows easy access to all information about the infrastructure project in a single place. This facilitates easy comparison of both the development process and the demolition process. If all of the different phases of models were modelled separately, it would be more difficult to switch between the existing plan and both of the different design options. Essentially, the use of a single building model is more informative for the stakeholders and is a huge timesaver.
