近日，位于纽约曼哈顿中城的前辉瑞总部大楼发生了一起施工安全事故。该建筑正参与一项将两栋办公楼改造成约1,600套公寓的项目 [1]。事故发生时，21层的某根钢结构柱出现屈曲现象，导致工程立即暂停并引发人员疏散 [1]。初步分析认为，此次事故可能由新增楼层的重量增加所致 [1]。
针对该事件，开发商 MetroLoft 方面未作正式回应，但其创始人承认在建筑顶部进行加宽操作可能对结构造成了伤害 [1]。这一意外突显了在现有建筑结构基础上增建楼层及改造内部空间以应对住房短缺时所面临的复杂工程挑战 [1]。尽管存在此类风险，约翰霍普金斯大学的 Ben Schafer 教授指出，从工程原理上看，这类适应性再利用项目对于解决城市住房危机至关重要 [1]。与此同时，旧金山工程师 Emily Guglielmo 强调，必须对原始设计假设进行审查以确保安全 [1]。
A structural column buckling incident at a former Pfizer headquarters building in Midtown Manhattan has halted construction and triggered evacuations during an effort to convert office space into residential units [1]. The accident involved a steel column on the 21st floor, which experts suggest may have been caused by the added weight of new floors being constructed as part of the project's expansion plans [1]. This event underscores the complex engineering challenges inherent in adding stories and modifying internal structures to address housing shortages within existing buildings [1].
Despite these risks, industry professionals maintain that such adaptive reuse projects remain essential for solving urban housing crises [1]. MetroLoft, the developer behind the initiative converting two office towers into approximately 1,600 apartments, has not issued a comment on the incident but acknowledged that widening the building's top could have caused harm [1]. While Professor Ben Schafer of Johns Hopkins University believes the engineering principles involved are feasible, other experts like Emily Guglielmo from San Francisco emphasize the need to review original design assumptions before proceeding with similar conversions [1].
