What Ysrael A. Seinuk does

Ysrael A. Seinuk, P.C. (YAS) is a New York-headquartered structural engineering firm founded in 1977 that provides consulting services for the design, analysis, and inspection of buildings and infrastructure. The firm's portfolio spans high-rise residential and commercial buildings, healthcare and educational facilities, courthouses and justice facilities, water and wastewater plants, bridges, hospitality venues, and mixed-use developments, with selected projects representing billions of dollars in construction value. YAS differentiates through specialized technical capabilities including structural design for severe wind and seismic environments, blast-resistant (anti-terrorism) design, waterfront structures, structures built over active transportation infrastructure, and landmark preservation, as well as pioneering use of high-strength concrete (notably the first use of 12,000-psi concrete in New York City at Trump World Tower) and innovative beam-less perimeter tube systems enabling slenderness ratios up to 18:1.

The firm operates as a B2B professional services business, charging project-based, negotiated fees to enterprise and institutional clients such as real estate developers, universities, healthcare organizations, and federal/state/municipal government agencies. Notable engagements include the Trump World Tower ($400 million, 880,000 SF), SUNY Buffalo Jacobs School of Medicine ($375 million, 628,000 SF), the Bronx County Hall of Justice ($275 million), MiamiCentral station-area residential towers over the Florida East Coast rail line, NYCDEP wastewater treatment plant upgrades, and the Alphonse D'Amato Federal Courthouse for the U.S. GSA. YAS is MBE-certified, holds a value engineering track record that has saved clients tens of millions on individual projects, and maintains an ENR NY 2018 Best Project Award of Merit among its industry recognitions.

The firm is a privately held professional corporation with no disclosed external investors, M&A activity, or funding rounds, and is led by its founder's name as a professional services brand. It distributes services through direct enterprise engagement and long-term relationships with architects and developers rather than through digital channels or intermediaries, relying on project portfolio visibility, industry awards, and professional referrals for new business development. Operating geographies include the United States plus documented international project work in the Philippines, UAE, and Mexico.
