Role of an Engineer in Parapet Inspection
Architectural Assessment
Get in the designer: educated eyes that can see beyond a few splits. They analyze load-bearing elements and check for activity in the structure. It's not guesswork-- dimensions, computations, and years of training back every recommendation.
Regulatory Requirements
The NYC Department of Buildings requireds parapet assessments to comply with Local Law 11 (Facade Inspection & Safety Program). Engineers file a Technical Report (TR1) and, after repair services, a TR2. Avoiding this procedure can bring about penalties or stop-work orders.
