You moved a design from Forma into Revit this week.
◦ What survived intact, and what did you rebuild? The overall building shapes, floor plates, and surrounding context buildings survived the transfer completely intact. However, I had to manually correct several geometric mistakes from the transfer, and I had to edit the existing walls and roof to add real thermal layers, proper materials, and specific performance properties. ◦ What does that tell you about what each tool is for? Forma is for quick, conceptual site analysis and environmental testing at the very beginning of a project. Revit is for detailed construction and documentation, where you turn those basic shapes into real building assemblies with accurate physical properties.
◦ Knowing where the handoff lands, what would you do differently in Forma next time? Next time, I would keep the geometry in Forma much simpler and avoid complex overlaps. Knowing that the transfer can introduce geometric errors, a cleaner mass in Forma will make the import into Revit much smoother and reduce the time spent fixing mistakes.
The core is located early and moved rarely.
◦ Why does it get fixed before most of the building? The core contains the main structural backbone of the building and the primary paths for egress (stairs) and utilities. Because everything else in the building relies on the core for stability and safety, it must be locked in early so other systems can be designed around it.
◦ What are the consequences of a core that does not stack vertically? If a core does not stack perfectly, it ruins the structural integrity of the building and becomes incredibly expensive. It breaks the continuous paths needed for columns, elevators, plumbing, and structural loads, making the building unsafe and chaotic to engineer.
◦ What did locating the core force you to change about your Week 3 layout? Locating the core forced me to reorganize the interior circulation paths. I had to adjust the layouts to ensure practical access to the primary stair and elevator in the main building, and position the second stair on the side to cleanly service the farthest corner from the center.
Your Insight result did not match your Forma result.
◦ What accounts for the difference? I think the main difference comes from the level of detail in the calculation. Forma uses a generalized baseline based on simple volumetric massing, on the other hand Revit’s Insight engine calculates specific material layers and exact wall-to-window properties that I edited in the project.
◦ Which number would you show a client, and how would you explain the gap? I would show clients the Revit number (544,214.38 kgCO₂e), it represents a more accurate look at the actual physical materials we chose for construction.
◦ Does a more detailed model automatically produce a more trustworthy prediction?
Not really. A detailed model is only trustworthy if the data put into it is accurate. If a model has bad thermal definitions or unassigned spaces, a detailed calculation will still produce errors, proving that a prediction is only as good as the settings you provide Revit to work with.
