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?
Using a single building information model for existing conditions as the foundation provides a cohesive and accurate representation of the current state, ensuring that any additions or renovations are seamlessly integrated with what’s already there. This unified model helps detect clashes early, ensuring proposed elements fit within structural constraints and existing systems. Additionally, maintaining a single model minimizes data duplication and the risk of inconsistencies between separate models, improving efficiency and collaboration across teams. It allows all stakeholders to access the latest version and understand both the current state and proposed changes in a single, updated model.
What sort of complexities are introduced when you construct a building complex in phases?
When constructing a building in phases, numerous complexities arise, especially at the interfaces where new phases meet existing structures. Managing utilities, access routes, and temporary structures becomes critical to ensure the site remains functional and safe throughout the phased construction. Structural, mechanical, and electrical systems must be carefully planned to connect seamlessly across phases. Planning for these complexities requires creating a detailed initial model that anticipates future connections and infrastructure needs. This approach allows for smoother transitions between phases, as the model helps identify potential conflicts early and guides decisions on temporary fixes or long-term adjustments to maintain continuity across the build.
