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专家的深入研究的产物，发现与传统的动手检查相结合，有效使用无人机可能会导致更全面的建筑检查，从而减少效率低下和更安全的纽约市，”纽约建筑专员Melanie E. La Rocca在有关该报告的释放的新闻声明中说。

根据现行的纽约市法规，自由无人驾驶飞机在城市上是不合法的。无人机只能从机场，直升机场和某些公园附近的指定区域起飞或起飞，而操作员需要视觉线才能驾驶无人机。这些和其他限制意味着在特定情况下或事先批准，无人机仅在城市中合法使用。

2020年，该市通过了地方法102，该法律要求纽约市DOB研究无人机与动手检查一起进行立面检查。新利18备用

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极限，作为人类视力的潜在替代。“无人机最常见的输出格式是二维图像，特别是照片。报告指出，高分辨率图像仍然可以通过平坦的观点来掩盖缺陷的程度，甚至视频可能会错过检查员可能需要确定是否存在重大缺陷及其程度或根本原因的关键角度。”在对该主题的进一步检查时，报告发现，从无人机图像进行工作的检查员可能会错过在街道或高处工作的检查员可见的缺陷。报告中引用了LIDAR，激光扫描或热成像设备的使用情况，但未充分评估。

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措施之前对问题进行进一步研究，但承认无人机使用正在不断扩大新利18备用，“纽约市将希望调查未来从广泛范围内确保公共安全所需的其他规则或准则观点。”

尽管该报告在其建议中相对谨慎，但迄今为止，该行业的反应一直是积极的。纽约美国工程公司委员会总裁兼首席执行官约翰·埃弗斯（John Evers）在报告中发表的一份声明中说：“今天是专业工程师潜在部署这种新工具以增加公共安全的重要一步。”“我们期待与DOB合作，以确保无人机技术得到适当有效地使用。”
