The transformative power of BIM.
Your building is a set of decisions, most made before you knew enough.
You produced roughly thirty deliverables across ten weeks.
The deliverable I learned the most from was the Week 4 wall section. In Forma, I only had to think about the wall as a color and a window ratio. But in Revit, I had to figure out each layer and how they fit together. I made a few mistakes with layer priorities and dimensions, and fixing them helped me understand how the wall actually works. I also learned why insulation is placed outside the studs and why the vapor retarder needs to be in a certain location.
At first, the Week 2 site analysis felt like busywork. I was just running sun and wind studies on an empty site, and I wasn't sure how useful they would be. But I ended up using those results later. The noise from Oxford St influenced my facade design in Week 3, and I used the summer and winter sun studies to work on the south overhangs this week. It was interesting to see how something I did early in the course became useful several weeks later.
Every model in this course was a simplification.
My Revit model looks much more realistic than my Forma model, but there are still many things missing. I haven't modeled the structural frame, beams, or foundation yet. I also haven't figured out the parking ramp, and I still need to add a stair in the podium. Since there are no beams in the model, I'm not even sure whether the 10 ft floor-to-floor height would leave enough space for mechanical systems. I also had some trouble with the carbon analysis because the software didn't recognize some of my custom materials, so I'm not sure how accurate those results are.
I think these simplifications are okay for a class project, especially when we are comparing different design options. But in a real construction project, these missing details would become much bigger problems. For example, without structural information, it would be difficult to estimate concrete quantities or coordinate mechanical systems. From my work experience, I've seen how missing design information can lead to change orders during construction. This course helped me understand a little better why it is important to identify those issues earlier in the design process.
What's next?
The part of this course that interests me most is how BIM can be used during construction, not just for design. I would like to learn more about constructability reviews, construction sequencing, and clash detection. This week, I found that one of my stairs was blocked by a slab. It was a small mistake in my model, but it reminded me of the coordination problems I've seen on actual construction projects.
I think my biggest gap right now is that I can create a basic model, but I still don't have enough knowledge to tell whether everything in it makes sense. For example, when Revit showed an R-value of 45 for my wall, I wasn't sure whether that was reasonable. I had to look into it to understand the result. I also need to learn more about building codes and how different building systems work together. I haven't had much experience coordinating structural and MEP models, so that's something I would like to learn next.
