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?
- Why not create a separate model for the new proposed design?
By using a model of the existing conditions, you can better ensure a smooth stitching from the previous to the new structure. This is especially important when considering building systems, like electrical or HVAC. From an architectural standpoint, it allows you to understand how aesthetic continuity may continue from one part of the building to another.
What sort of complexities are introduced when you construct a building complex in phases?
- What happens at the interfaces between the buildings as the phases advance?
- How can you plan and prepare for these complexities as your create your initial building model?
Logistically, it can be hard to toggle back and forth from one phase to another. Constructing in phases also introduces some sensitivities from the software that require special attention to be paid to where the new and existing structures come together. If you do know that a part of a building will be extended in the future, it may be beneficial to identify what parts of the building could be demolished from a new addition
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?
- Why not create a separate model for each of the design alternatives?
In your project, which features of the proposed design did you choose to model as design alternatives?
- Why did you choose these building features? And what were the biggest challenges in modeling them as the design alternatives?
