What are the primary goals of creating a building model? Who are the key stakeholders?
- What do they need?
- What do they care about most?
Key stakeholders include:
- Owner/developer (end customer) - they care most about meeting their usage and cost needs.
- Architect - focused on the overall experience of the building (aesthetics and space).
- Engineer/constructor/contractor - focused on materials, dimensions, and feasibility of configurations.
All stakeholders need a visual building model to communicate their ideas with each other in a way that makes it easy to identify and markup critical areas of the design.
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
- Define main materials
- Preliminary design
- Define dimensions (thickness etc.)
- Design development
- Define layer composition (go into the detailed thickness and materials) for thermal/cost analysis
- Construction documentation
- Define specific finishes
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?
Manufacturers provide Revit families of their products for advertising. It allows designers and their end customers to place products in the building model and go see the product in real life at a showroom (or online photos). The benefit for designers is that manufacturer-provided families incorporate the properties of a real product that's available for purchase.
