A Scare That Got Our Attention
Every so often, a story comes across our feed that stops us mid scroll. Earlier this week, that story was coming out of Midtown Manhattan at the former Pfizer building, where a high rise office building undergoing conversion into residential units began showing serious structural distress. Load bearing columns on the twenty first floor buckled, several surrounding blocks were closed off, and multiple nearby buildings, including a hotel and a school, were evacuated as a precaution.

We want to be upfront about something before we go further. We were not on site, we are not the engineers of record on this project, and we do not have access to the calculations, the drawings, or the forensic findings that will eventually explain exactly what happened. What follows is our reaction as a structural, architectural, and MEP engineering firm watching this unfold in the news, offered in the spirit of education rather than diagnosis. We think there is real value in talking through what buckling actually means, why it happens, and what responsible engineering looks like when a structure starts to move in ways it should not.
What We Know So Far
Based on public reporting, the building at the center of this story is a large scale commercial to residential conversion, one of the biggest office to apartment projects the city has seen. The structure combines a shorter section of roughly twenty two stories with a taller thirty seven story tower, and crews had recently topped out an additional eleven story vertical extension built on top of the lower section. Fire officials responded after reports of debris falling from upper floors, and a closer look revealed that two load bearing columns on the twenty first floor had buckled, causing the floors above to sag and crack.
Investigators have not yet determined a cause, and officials have said publicly that the added weight from the new vertical extension is one of the factors under review. Engineers used monitoring equipment and drone surveys to track ongoing movement in the columns, and a multi block area was closed to traffic and pedestrians until the site could be stabilized. As of the most recent updates, crews were working to install temporary struts and trusses to redistribute the load away from the damaged columns before a full forensic investigation begins.

It is worth pausing on that last point, because it says something important about how structural emergencies are actually handled. Nobody rushes in to diagnose the root cause on day one. The first job is always to make the structure safe enough to approach.
Why Columns Buckle in the First Place
Buckling is not the same thing as a column simply being crushed under too much weight. A column buckles when it can no longer resist bending sideways under a compressive load, even if that load is technically within what the material could handle if it were perfectly straight, perfectly supported, and perfectly aligned. The slenderness of the column, the bracing around it, and the straightness of the load path all determine how much capacity actually exists in practice.
In a finished, fully braced building, that load path is continuous and predictable. During construction, and especially during a conversion project like this one, that is not always true. Floors may be temporarily unbraced, new loads can be introduced before the structure below has been verified to carry them, and sequencing changes can shift weight onto elements that were never intended to be the primary path for it. Adding new floors on top of an existing structure, as appears to have happened here, changes the compression demand on every column beneath it. If that added demand was not fully accounted for, or if construction tolerances stacked up in the wrong direction, a column that looked fine on paper can behave very differently in the field.
This is exactly why adaptive reuse and vertical addition projects deserve a different level of scrutiny than new ground up construction. The existing structure was designed for a specific set of assumptions, and every change to those assumptions needs to be traced all the way down through the building.
The Value of Watching Before It Moves
One detail from this story stood out to us. Once the buckling was discovered, officials did not simply assume the danger had passed once the initial movement stopped. They installed monitoring equipment and used aerial tools to track continuing shifts in the columns, because a structure that has already lost some of its original strength can keep moving in small, dangerous increments long after the initial event.
This is the same principle behind routine structural inspections on completed buildings, particularly in coastal environments like South Florida, where corrosion, moisture intrusion, and storm loading can quietly erode capacity over years. The earlier a problem is identified, whether through a scheduled inspection or through instrumentation, the more options everyone has. Waiting until cracks are visible from the street is the most expensive and most dangerous way to find out something is wrong.
Stabilizing First, Investigating Second
The stabilization plan described in news reports followed a sequence that we see as sound engineering practice. Before crews entered the affected floor, the rate of movement had to slow to a level considered safe to work around. Once that threshold was met, the plan called for temporary struts and trusses designed to carry load away from the compromised columns, giving the structure a new, safer path for that weight while the long term investigation and repair plan take shape.(Source:Fox 5 New York)
That sequence, monitor first, stabilize second, investigate third, repair last, is the same logic that guides how we approach any structure that has shown signs of distress, whether that is storm damage, deterioration, or an unexpected finding during a renovation. Skipping ahead to root cause analysis before a structure is safe to approach is how people get hurt.
What This Means for Every Building Under Construction
We do not need a headline out of New York to know that construction sequencing, temporary bracing, and load path continuity matter. We see it in our own work across Broward, Miami Dade, and Palm Beach Counties every time we take on a renovation, an addition, or a conversion project. A structure that has stood safely for decades can behave very differently once you start changing what sits on top of it, and that is precisely why we approach every project with construction minded thinking from the very first sketch.
Our team provides Structural Engineering services built around exactly this kind of scrutiny, verifying that existing load paths can safely support new conditions before a single beam is set. We pair that with Architectural Design that respects the realities of the structure underneath it, and Inspections that catch early warning signs long before they become emergencies. For waterfront clients, that same philosophy carries over into our Seawall and Docks work, where erosion and hidden deterioration follow a similar pattern of quiet progression until someone is watching closely enough to notice.
NOHMIS provides full-service Architecture, Structural & MEP Engineering, and we built our practice on the belief that safety is never something you retrofit into a project after the fact. It has to be designed in from the beginning and verified every step of the way.
Built to Stand, Not Just to Rise
A story like this one is a reminder that a building is never really finished settling into its own loads, especially while it is being changed. Columns, beams, and connections are only as reliable as the assumptions behind them, and those assumptions deserve to be checked, monitored, and questioned throughout a project’s life, not just at the ribbon cutting. Whatever the investigation in New York ultimately finds, the lesson for our own work stays the same. Respect the load path, verify before you build on top of it, and never mistake a quiet structure for a stable one.
If your project involves a renovation, an addition, or any change to an existing structure, we would welcome the chance to look at it with you before the first change is made rather than after.
