Drones have only seen limited use in New York City for construction documentation and facade inspections due to restrictive local ordinances. But that may be changing with the release of a new report from the New York City Dept. of Buildings, which sees future potential for unmanned aerial vehicles (UAV), or drones, to be used in building facade inspections.

“我们的报告是DOB专家密集研究的产品,发现,当结合传统的实践考试时,有效使用无人机可能会导致更全面的建筑检查,导致效率降低,纽约市更加安全。纽约市纽约大厦委员会委员委员会委员会E. La Rocca在一份关于该报告发布的新闻陈述中。

根据目前的纽约市法规,在城市中自由飞行无人机并不合法。无人机只能从机场,直升机场和某些公共公共公共公园附近的指定区域落地或从指定区域起飞,并且运营商需要视觉视线才能试用无人机。这些和其他限制意味着无人机在特定情况下或事先批准的情况下仅在城市中使用。

2020年,该市通过了本地法律102,该法律要求NYC Dob研究无人机的使用与实践检查一起进行外立面检查。新利luck

The resulting report, "Using Drones to Conduct Facade Inspections," outlines the current state of drone inspection technologies and the many hurdles to adopting them for facade inspections within New York City. Growing usage of drones in other industries in recent years has spurred the city to consider the issue, but the report found the available technology still falls short of meeting all the requirements for performing building facade inspections.

具体而言,该报告突出了无人机摄影的限制作为人类视力的潜在替代品。“来自无人机的最常见的输出格式是二维图像,特别是照片。高分辨率图像仍然可以通过展平视点来掩盖缺陷的程度,甚至视频可能错过检查员可能需要确定是否存在显着缺陷及其范围或基本原因的关键角度,“报告状态。在进一步审查该主题的情况下,该报告发现,妨碍无人机图像的检查员可能会错过在街道层或身高工作的检查员可见的缺陷。在报告中引用了安装在无人机上的激光扫描,激光扫描或热成像装置,但未完全评估。

While the report doesn’t see drones replacing human building facade inspectors any time soon, it does see potential for the technology as a way to identify problem areas ahead of in-person inspections. One possible side benefit of using drones for a sort of “first-pass” facade inspection is reducing the amount of sidewalk sheds and scaffolding needed before in-person inspections. “For example, instead of providing a sidewalk shed at two faces of a building, the drone inspection, after being evaluated by the [facade inspector], may demonstrate that a shed is only needed at a portion of one face of the building,” the report states. While this is only a hypothetical situation, it does offer one way that drones could speed up inspections in the city, where erection and maintenance of sidewalk sheds and scaffolding have been a point of contention for years among safety advocates and building owners.

But despite the potential for drones to aid in facade inspections, the report concludes that there is simply not enough available data on drones being used for facade inspections to offer a judgement either way just yet. While there is some precedent established for drone use in construction, the report notes that “in construction, drones are most commonly used to gather data from large sites to assess progress and not necessarily to identify finer details.”

Additionally, NYC DOB researchers found few instances of drones being used for facade inspections in other U.S. cities, even in places where drone usage is more widely permitted. Drones have been used for inspections of critical infrastructure such as bridges and rail trestles, but their use for building facade inspections remains rare, the researchers write. “Without more concrete information, any benefits or increases to public safety from the use of drones remain incalculable.”

该报告最终建议在采取任何行动之前进一步研究该问题,但承认无人机使用是不断扩大的,并新利luck且“该市将希望调查以确保未来的公共安全所需的附加规则或指导方针。观点。“

虽然报告相对守护到其建议,但行业答复到目前为止是积极的。“今天是通过专业工程师潜在部署这一新工具的重要一步,通过专业工程师提高公共安全,”纽约美国工程公司委员会的总裁兼首席执行官John Evers表示,在该报告旁边发布的声明。“我们期待使用DOB,以确保无人机技术适当地使用。”
