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?
Constructing a structure in phases introduces challenges related to structural continuity and integrity. It’s essential to ensure that elements connecting different phases are precisely aligned and stable enough to support the loading from multiple phases. Additionally, integrating the mechanical, electrical, and plumbing (MEP) systems between phases can be complex.
To address these complexities, careful documentation of the overlap locations between phases is crucial. Filtering each phase and simulating its interactions with previous ones in the building model helps identify potential issues early. Lastly, designing adaptable rooms that can be modified for future adjustments provides flexibility and prepares the structure for evolving requirements.
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?
Using a single building information model ensures consistency and minimizes potential errors across design alternatives. This approach also saves time, as it eliminates the need to recreate the existing building for each alternative. Additionally, a unified BIM simplifies the comparison of proposed designs, allowing for easier analysis and decision-making. It also promotes efficient collaboration among engineers, contractors, clients, and other stakeholders. By contrast, creating separate models for each alternative would be labor-intensive, increase the risk of inconsistencies, and complicate coordination.
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?
