BIM for Architects and Engineers - Group D - Week 3

Chapter 5 of the BIM handbook discusses the transition of the design process between past methods and new advancements in building information modeling.
This transition yields several benefits for both engineers and architects beginning with consistency. BIM design allows architects and engineers to work in a consistent format across all drawings and reports for the project. From this form of organization, communication between both parties is never broken or skewed which allows all parties involved to be on the same page. In addition, the benefit of BIM allows architects to provide enhanced visuals from 2D drawings and renderings to detailed 3D models in practice.  The models then can be subject to simulations and analyzed for more accurate cost savings. By using software, a cost savings analysis can be performed in a building model based on assemblies, recipes, or items and correlate them to a cost database like RSMeans.

            In Brian’s post, he discussed the former issues between architects and engineers and how architects refused to take responsibility for construction projects because their drawings were not exact designs and lacked explicit details that the contractor had to address on site. Brian also mentioned the fallout method due to these issues such as Design-Bid-Build and Design Build. He further went on to write how the addition BIM has restructured the bidding process with Integrated Project Delivery system. This system allows the streamline of documentation by vesting the designer in the completion of the project to benefit from the building like the contractor.

Comment on Brian Benson’s Post

I enjoyed reading your post. Like Ryan said, it proved to be a very accurate summary of the entire chapter. The first design challenge for BIM that you stated in the second paragraph where you described the definition of the design process and roles of the team members was an aspect that I overlooked in the chapter. I didn't think it was a major concern until I read your post.

Comment on Stephen Bartal's Post

Stephen, your summary of parametric modeling was very informative. The capability of modifying a few parameters to change all of the desired elements is significant time and cost saver. The incorporation of your own personal story regarding the Revit and AutoCAD was interesting to me. I hardly use Revit anymore, but the parametric modeling function makes it more appealing. I used to spend hours making tedious changes similar to your story, but now I see that there's finally a way to lessen the time required on making late changes to documents and projects.

Comment on Melanie Wayne's Post

Did the chapter list the software used by these smaller firms and how expensive are these licenses? I found your discussion on 4D modeling very eye-opening. The incorporation of time in the models, I believe, is remarkable since it impacts coordination and project budgeting.
