What does forensic investigation in architecture focus on?

Forensic investigation in architecture primarily focuses on emerging and evolving building defects. This area is critical for understanding how and why structures fail or show signs of deterioration over time. Forensic architects examine existing buildings to identify, analyze, and document failures, which may include issues such as material degradation, design flaws, or construction practices that have led to defects. This investigative process allows professionals to gather evidence and insights that can prevent future failures, improve building practices, and ensure the structural integrity and safety of buildings.

The other choices, while relevant aspects of architecture, do not specifically pertain to the forensic investigation's primary objective. Design efficiency relates to optimizing building performance and usability, the historical significance of buildings entails evaluating their cultural or architectural value, and community integration focuses on how buildings fit within their urban or social contexts. Thus, they do not align with the forensic investigation's focus on diagnosing and understanding defects in existing structures.
