What types of building information are best portrayed in 3D views?
- Which stakeholders require 2D views, and why?
Construction teams best see layouts in 2D because, inherently, floors are built on a plane level with gravity. It is much easier to see distances walls are apart, calculate square footage, and locations of doors and windows in 2D. Lighting on building, shadows, general aesthetics, architectural features, as well as relationship with respect any grading are best shown in 3D. In advanced modeling, 360 degree panoramic views help one envision potential surroundings and layouts once a project is complete.
Give examples of how the building information for a specific location in the project needs to be filtered for different audiences and purposes?
Let us assume we have a final drawing with every possible building information in it - dimensions, grading, furniture layout, schedules, tags, and 3D renderings. A construction team does not need to know where the furniture will go when someone moves into the building. Therefore, that information can be eliminated in drawings given to the construction team. A marketing team may only care about aesthetics and views so they can better sell rental space or living quarters for sale to potential renters/buyers. Hence, only 3D rendering with small 2D square footage layout maps will be needed by them. Accountants may only need schedules of materials being used to calculate cost and labor, and total square footage for potential revenue and therefore none of the 3D drawings or 2D layouts may be useful to them.
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?
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?
Schedule views provide itemized and grand total of necessary materials needed for a construction project. That information allows construction teams to estimate a cost for doing a project as well as be able to create a timeline for construction. If non-standard or items made of exotic materials are required, then this information can be implemented in the grand plan before any ground is broken.
