The unfolding structural emergency at the former Pfizer headquarters on East 42nd Street in Midtown Manhattan raises urgent questions issues such as load limits, weight redistribution, structural steel, emergency shoring and in general the challenges of converting older office towers into residential buildings.

As officials and engineers continue to investigate what happened, the incident points to a larger issue facing many major cities: how safely can older commercial buildings be adapted for new uses, especially when vertical additions, new floor loads and major structural modifications are involved?

ExpertFile has a range of structural engineering experts available to help journalists and audiences understand the engineering issues behind this story.

Featured Experts

Edward Sippel, P.E., Ph.D.

Assistant Professor, Milwaukee School of Engineering

Edward Sippel is an expert in structural engineering at the Milwaukee School of Engineering with a focus on steel structures, stability and structural analysis. His expertise in structural steel, finite element analysis and nonlinear analysis makes him especially relevant to questions about column buckling, steel-frame behavior, temporary reinforcement and how engineers assess whether a damaged steel structure can be stabilized or repaired.

David O. Prevatt

Professor, University of Florida

David O. Prevatt is a structural engineer at the University of Florida whose areas of expertise include structural load paths, structural engineering and resilient building performance. His expertise is especially relevant to explaining how loads move through a building, what happens when weight is added or redistributed, and why engineers must understand the full path that gravity loads take from upper floors down to the foundation.

Key Questions Experts Can Address

How do added floors or major renovations change the way weight moves through an existing building?

What causes a steel column to buckle, and how is that different from other types of structural failure?

Why do transition points between older and newer parts of a structure require special attention?

How do engineers use temporary shoring, jacks and steel reinforcement to stop movement during an emergency?

What should cities, developers and regulators consider as office-to-residential conversions become more common?

Additional Structural Engineering Experts Available

Beyond load paths and steel mechanics, this story also raises broader questions about structural health monitoring, building inspections, retrofits, aging infrastructure, concrete systems, structural dynamics and resilient design. ExpertFile includes additional experts who can speak to these related issues, including:

For journalists covering the Manhattan high-rise situation, office-to-residential conversions, emergency building stabilization or the future of urban infrastructure, these experts offer relevant structural engineering expertise that may help add context, clarity and perspective to your reporting.

25 Years Later: How 9/11 Changed the World

On September 11, 2001, the world watched as nearly 3,000 people were killed in terrorist attacks that would become one of the defining moments of the 21st century. Twenty-five years later, 9/11 remains much more than a moment in history. Its consequences continue to shape the world we live in. The attacks transformed national security and intelligence, changed how people travel, reshaped airport and border security, and ushered in a new era of surveillance and counterterrorism. They also profoundly influenced American foreign policy, leading to wars in Afghanistan and Iraq and decades of debate about security, military intervention and America's role in the world. The effects were cultural as well as political. September 11 changed how a generation viewed safety, terrorism and global conflict. It also sparked difficult conversations about civil liberties, immigration, religious tolerance and the balance between individual freedoms and collective security. For younger generations, 9/11 is increasingly an event learned about rather than remembered. For millions of others, memories of where they were and what they saw that day remain remarkably vivid. A quarter-century later, the anniversary offers an opportunity to remember those who were lost, recognize the first responders and countless others affected by the attacks, and examine how the decisions made in their aftermath continue to influence our world. Experts in history, political science, international relations, national security, terrorism, public policy and sociology can help provide perspective on September 11, its legacy and how the world has changed 25 years later.

More Than a Long Weekend: Why Labor Day Still Matters in America

For millions of Americans, Labor Day means the unofficial end of summer , a final long weekend before schools are back in full swing and the fall routine takes over. But behind the barbecues, travel and end-of-summer sales is a holiday rooted in the history of American workers and the transformation of the workplace. Observed on the first Monday in September, Labor Day recognizes the social and economic achievements of American workers. Its origins date to the labor movement of the late 19th century, with the first Labor Day celebration held in New York City on September 5, 1882. In 1894, it became a federal holiday. More than 130 years later, Labor Day remains an opportunity to look at the role work plays in American life, particularly at a time when the workplace itself is undergoing enormous change. Artificial intelligence and automation are reshaping jobs and industries. Remote and hybrid work have changed where and how millions of people work. Employers continue to navigate workforce shortages, recruitment and retention, while workers are reconsidering expectations around compensation, flexibility, benefits and work-life balance. Labor Day can also open the door to broader conversations about the American labor movement, organized labor, workplace protections, wages and the economic contribution of workers. For journalists, that makes the holiday much more than a date on the calendar. It's a timely opportunity to explore both how work in America has changed and where it is heading next. Experts across economics, business, labor relations, history, human resources, public policy and emerging technology can provide valuable perspective on Labor Day and the changing American workplace. Journalists covering Labor Day and looking for expert perspective on the history of the holiday, labor and employment, workplace trends, organized labor, artificial intelligence and the future of work can connect with experts directly through ExpertFile profiles below:
