A criminal investigation has been initiated into the structural issues plaguing a 37-story skyscraper in Midtown Manhattan, which was evacuated Tuesday after construction crews discovered buckling interior columns. The New York City Department of Investigation and the Manhattan District Attorney's office are leading the probe into the cause of the incident.

The 21st to 26th floors of the building, located near Grand Central Terminal, caved in under stress, with multiple cracks and sagging floors reported throughout the high-rise. The building was in the process of being converted from office space to residential apartments, a project described as the largest residential conversion in the United States. This complex undertaking involves numerous subcontractors, companies, and developers, which is expected to make the investigation lengthy, potentially taking months or even years, and may conclude without charges.

Nathan Berman, founder of MetroLoft, one of the developers, described the event to The New York Times as a "typical construction mishap." He noted that issues such as falling cranes or windows are unfortunately common on construction sites. However, union and city workers have highlighted significant problems, including the buckled columns that were only identified when the building nearly collapsed.

This is not the first time MetroLoft has faced scrutiny for structural issues. The company is currently involved in a lawsuit exceeding $350 million concerning a Tribeca apartment building. The suit alleges numerous structural defects in that property, with claims escalating from an initial $250 million to $376 million. Legal complaints began mounting in 2022 after MetroLoft converted a former bookbinding factory into a luxury residential building.

Stabilization Efforts and Structural Concerns

Work continues on stabilizing the building, though the investigation is still in its early stages. Experts have warned that the building, formerly the headquarters for Pfizer, might require demolition. However, even demolition carries risks, potentially triggering a collapse and causing widespread distress, drawing parallels to the trauma experienced during the September 11, 2001, attacks.

Construction crews discovered that two inside columns had begun to buckle

Structural engineer Emily Guglielmo told the New York Post that visible damage such as buckled columns, cracking, and sagging floors is often irreversible. She suggested the need for temporary bracing and shoring to stabilize the building, but cautioned that such measures could be too risky. Ronald Hamburger, a structural engineer who investigated the World Trade Center collapse, stated the building is in "significant danger" of a localized collapse. He explained that the remaining intact beams and columns are under immense stress, with the failed columns now supporting only a third of their intended load. Hamburger recommended rapid installation of brackets to re-level the building and replacement of the failed columns to prevent further damage.
