We’re excited to share a powerful technique for construction defect cases. We’ve applied it in a variety of cases over the past few years, but haven’t been able to brag about it because those cases are still confidential. We really like this technique, though, so we created a little demo project to show it off.

It’s a multi-platform interactive assembly diagram that lets you “peel away” the layered building components to systematically understand how they fit together and compare as-built conditions with the designed details. Follow this link to see the web version (we also make more feature-rich standalone versions — but we’ll save that for another post).

This example shows a hypothetical garage addition in which the designer specified roof trusses with eaves, but the builder substituted an abbreviated eave detail and failed to install flashing (resulting in moisture infiltration). The first series of slides provides context by orienting the viewer to the building and the area of detail. The second series is where the magic’s at: an interactive collection of section diagrams makes it possible to see inside the assembly and peel away the layers to understand the order of construction, the function of individual materials, and the difference between how the building should have been built and how it actually was.
