Why do we need to think, detail & specify in 3D to ensure proper specification of expansion joints

Designers and architects often get stuck in the rut of thinking and designing in two dimensions. You have to ensure that your design is fireproof and waterproof, but once it's built, what happens next?


Well, the building will expand and contract with temperature changes, which puts stress on the joints between materials—and if they aren't adequately designed or detailed, that stress can cause leaks or other problems. You need to think about expansion joints in 3D!

We need to draw an isometric schematic showing how it will be laid out on its foundations. We also include isometric details of changes in plane and direction. These details help us ensure that our design will hold up over time without leaks or other issues.

When designing a building, we must consider how it will be constructed. What materials will you use? How much space is there between the materials? Will they expand at different rates with heat and cold? These questions need to be answered before the building can be constructed.

If you’re designing a building, try to think about the materials that would be used in its construction. How will they expand and contract with heat and cold? What happens when two materials are placed next to each other? If you’re drawing an isometric drawing of your building, include details showing how it will expand and contract over time.
