Module 5 - Points to Ponder

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?

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?

I found it hard to keep track of the things I demolished and when I demolished them. You can’t delete the element whenever you want. You have to put a pin on when and where you want it to be demolished.

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?

Using one model with existing conditions in revit allows for high accuracy and efficiency. If we were to intergrate older elements or new elements within the single model we could run into load problems and layout issues. We save time and ensure that we won’t run into these types of problems.

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?
