Introduction
As modular and prefabricated construction methods are increasingly adopted, so too are the potential challenges that come with them. The appeal is straightforward: faster timelines, controlled fabrication environments, and reduced on-site labor demands. But the risks that accompany these benefits are often less clear—and, in many cases, poorly defined.

For example, what happens when a prefabricated component is delayed past its installation window? Who is responsible for a defect discovered inside a sealed, installed module? What happens to warranty obligations when a prefabricated component must be modified on site?
