A parapet is the low wall surface prolonging above the roofline, often crowned with decorative elements. In NYC, these functions aren't just for show-- they protect against people and particles from slipping off roofs. With time, weather and wear can compromise their stability.
Importance in Building Safety
When a parapet fails, blocks or rock fragments can fall onto sidewalks below. That's not simply a costly repair service-- it's a severe hazard. Normal assessments indicate detecting trouble before it comes to be a heading.
Duty of an Engineer in Parapet Inspection
Architectural Assessment
Enter the engineer: trained eyes that can see beyond a few splits. They assess load-bearing components and look for motion in the structure. It's not guesswork-- measurements, computations, and years of training back every referral.
Regulative Requirements
The NYC Department of Buildings requireds parapet evaluations to adhere to Local Law 11 (Facade Inspection & Safety Program). Engineers submit a Technical Report (TR1) and, after repair work, a TR2. Missing this process can lead to fines or stop-work orders.
