GMS congratulates our Principal, Tim Barnard, on his retirement and celebrates his remarkable career in structural engineering.

Originally from the United Kingdom, Tim began his career in London after earning a Bachelor of Science and Technology from the University of Manchester Institute of Science and Technology. His professional journey eventually brought him across the Atlantic and led him to GMS, where he spent nearly 30 years shaping the firm and its legacy. With over four and a half decades of experience in structural engineering, Tim’s portfolio spans high-rise office towers, public institutions, schools, retail renovations, residential buildings, and hospital projects across the United States, the Caribbean, and Europe.

Top of the Rock, located on the 67th, 69th, and 70th floors of 30 Rockefeller Plaza in Midtown Manhattan, is one of New York’s most iconic observation decks. As part of a recent revitalization effort, the owners aimed to introduce new, immersive visitor experiences that involved installing two amusement rides on the roof of the historic skyscraper. Construction had to be meticulously planned so that the observation deck could remain open to patrons throughout construction. In recognition of the project’s creative approach to adaptive reuse, it was honored with the 2025 AISC IDEAS² Award for Excellence in Adaptive Reuse of Steel Structures.

On May 28, GMS Partner and GeoHazards International (GHI) Board Trustee Ramon Gilsanz delivered a powerful presentation at the Real Academia de Doctores de España in Madrid. His talk, titled “Preparedness for Earthquakes, Tsunamis, and Landslides,” highlighted the critical importance of disaster mitigation and the proactive implementation of preventive measures—particularly in less developed countries—to reduce the devastating impacts of natural hazards.

At the 2025 American Society of Civil Engineers SEI Structures Congress, several GMS team members joined fellow industry leaders to discuss critical issues shaping the future of structural engineering.

In December 2024, the New York City Council officially adopted the City of Yes Zoning for Housing Opportunity. The City of Yes initiative aims to minimize parking restrictions and provide new housing opportunities across all five boroughs. In April 2024, New York State enacted the 467-m tax incentive program, known as “Affordable Housing from Commercial Conversions,” to bolster the transformation of non-residential buildings into affordable housing. And with the recent growing trend of converting existing underutilized or abandoned office spaces into state-of-the-art residential buildings, the possibilities are endless. As structural engineers, we have a critical role in understanding the many challenges and complexities that come with these projects.

GMS teams are bringing the energy, from big wins to kicking off new seasons!

The highly anticipated Pearl House, a luxury residential conversion in the Financial District of Lower Manhattan, opened its doors to new tenants early this year. Developed by the Vanbarton Group and designed by Gensler, this $273 million project is the largest office-to-residential conversion in the city’s history.  Pearl House boasts 588 market rate luxury apartments right in the heart of the Seaport district and offers water views and luxury resort-style amenities to its tenants. Residences range from studios and one- and two-bedroom apartments to penthouses with private terraces.

In cities like Manhattan, where urban development and water bodies converge, floodproofing of structures is not just a regulatory requirement but a crucial aspect of building design. The coastal geography of New York City is considered highly vulnerable to flooding from extreme weather conditions. As we witness climate change and sea level rise, we anticipate flood risks to increase.

In a recent AIA NY presentation on flood and hurricane mitigation, a panel of experts, including building envelope consultants, a structural engineer, and an architect, shared their insights on addressing the challenges posed by extreme weather events in New York City. The discussion covered Flood Zone and Wind-Borne Debris Region designations, relevant building codes, and real-world applications, highlighting critical construction details from ongoing projects.

In this article, we will focus on Daniel Kinsley’s portion of the presentation, where he shared his expertise on flood mitigation for building envelopes. A future article will summarize Jessica Mandrick’s structural engineering perspective. GMS has completed several projects that showcase innovative floodproofing strategies to enhance building resilience and safety.

One Madison Avenue, one of New York City’s iconic structures, has undergone a major transformation, marking it as one of the most significant adaptive reuse projects of the 21st century. Originally constructed in 1893 by the renowned architectural firm Napoleon Le Brun & Sons, One Madison Avenue was once among the largest office buildings in the city, spanning an entire block between Park and Madison Avenues, from East 23^rd to East 24^th Streets.

GMS is pleased to announce the promotion of Michael Pugliese to Associate Partner and Clara Cruz to Project Manager. Additionally, we are excited to welcome Susan Haynes to the building envelope team as an Associate. We look forward to celebrating the continued accomplishments of these talented colleagues.
