Avoiding failure in major construction projects with thousands of units of glass-based products like windows, curtain-wall, and glass balustrades, may seem impossible given how often failures occur. In its conclusion, this presentation will demonstrate a feasible process by which to avoid these failures, but also what kind of failures they are and how to identify them in various phases of a project cycle. To lead with, a series of failed specimen will be presented, in context, with their respective and nuanced issues. Following which the exploration of resulting organized lessons will be discussed. Finally concluding with a formalized process for prevention to empower project teams and professionals to avoid these types of failures themselves.
