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?

  • What do they need?
  • What do they care about mo

The goal of creating a building model is to keep everyone in a construction project on the same page and facilitate communication. BIM is a really powerful tool because it contains or it can contain as much information as possible. Assuming the model is very complete (has all information needed). The developer gets to see how the building may look like in 3D, how much it might cost, how much energy it needs. The designer gets to work on a single model without printing new drawing sets or addendums, which delays communication. The contractor gets to use BIM to select the manufacturer, see the item schedule, etc. I think everything that these people may care about can all be found in the BIM model.

How much detail should you include in your building model? How do you decide?

  • As you develop your initial design?
  • As you continue to iterate and develop on your design?
  • What are the key stages?
  • And how much detail should you include at each stage?

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
  • Preliminary design
  • Design development
  • Construction documentation

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?

I think the biggest advantage to manufacturers are advertising. BIM is not just coming up with a building model but including information as well. If a manufacturer made a window/door family of his or her product, he or she would certainly put down the company name in the manufacturer tab, a link to the product spec, price, weight, contact information, etc. If this window/door is chosen, the contractor or designer may very likely contact the manufacturer that made this family and order from them.

The benefit to me as a designer is that I know that this type of window/door can actually be made by someone, and I have a 3d model to see if it fits well with my design.

What are the advantages of getting the Revit component families (for furniture, equipment, and fittings) directly from the manufacturer versus from an online sharing website like RevitCity.com?

I believe this will make the revit component more accurate and realizable. It would also save contractor a lot of time trying to find a manufacturer who can meet the designer's expectation.
