Module 2 - Points to Ponder
Please share your comments on 3 of the following Points to Ponder questions. (Choose 3 of the 5 questions below.)
What are the primary goals of creating a building model? Who are the key stakeholders?
- The key objective of BIM is stakeholders including architects, structural engineers, contractors, and clients can share the same information through the 3D model.
- It is difficult for clients who do not have expertise to understand the shape of a building from 2D drawings, which leads to more time for them to make a decision. BIM is expected to address this problem. Facilitating decision making smoothly advances a project.
How much detail should you include in your building model? How do you decide?
- At the beginning of design, detailed information is not necessary because of a high possibility to change a building model. Geometric information such as a shape and volume should be considered in the initial phase.
- As design is getting fine, the building model should include more information such as the layout of rooms, position of doors and windows, and arrangement of furniture.
- There are three key stages, design, construction, and operation, and the building model in each stage requires different information.
- In a design phase, the information mentioned above is required. In a construction phase, a schedule and cost should be included to manage a construction project. In an operation phase, the records of construction and repair are expected to be reflected in the model.
How much detail should you include about the composition (layers, materials, thicknesses) of your wall, floor, and roof assemblies at different stages of your design process?
- Conceptual design: Geometric information such as shape and volume.
- Preliminary design: More detailed information than the previous stage such as layout.
- Design development: The size of members, and position of doors and windows should be determined.
- Construction documentation: The materials and products should be designated in the model.
Many door and window manufacturers provide Revit families for doors and windows that you can specify for your building design.
- What is the advantage to manufacturers for providing these families? (it's not free to create and provide them...)
- What is the benefit to you as the designer of using these manufacturer-provided families? Is there an advantage to using them versus the families provided in the Revit library?
