What types of building information are best portrayed in 3D views?
- Which stakeholders require 2D views, and why?
Most individuals, regardless of skills or technical background, find it difficult to gauge the interior and exterior scale of structures using purely 2D dimensions. This is especially true for clients with non-technical backgrounds, but also for designers including architects and engineers. While 2D views are important for dimensions, accuracy, and construction, 3D views are best for communicating overall experience of the building, which is what clients future occupants care most about.
Give examples of how the building information for a specific location in the project needs to be filtered for different audiences and purposes?
Should your design ideas always be conveyed through photorealistic renders?
- How does the level of detail in the rendering and its presentation affect the perception of stakeholders reviewing your design?
As mentioned during the check-in session, photorealistic renders create a sense of permanence and inflexibility due to their "finished" nature. This will not only make clients apprehensive about the direction a project is headed in, but also make other members of the design team such as engineers feel stuck when trying to make their designs because they may overestimate how much of the architectural intent is set in stone. Therefore keeping the level of detail low in BIM representations might sometimes be good for encouraging both the clients as well as the rest of the design team to discuss improvements or even suggest big changes.
Name some applications where viewing the building and model information in virtual reality or augmented reality would be most beneficial?
- Are there advantages to using a C.A.V.E as a virtual environment versus VR headsets?
How can schedule views be used to assist with procurement and model-based estimating?
It is much more difficult to estimate quantities through repeated markups of PDFs, and certainly impossible to do so by looking at a 3D model, compared to looking at itemized schedules. Schedule views allow construction managers, engineers, quantity surveyors etc to easily obtain material takedowns and produce cost estimates of the project. Furthermore, because these views are linked directly to the model. they are automatically updated when changes are made to the designs. These schedules can also be linked to Excel files and dynamo or grasshopper scripts for faster calculations and optimization.
