On the evening of Saturday, May 17, 2025, San Francisco’s skyline shimmered in a dazzling, unexpected fireworks display that left thousands in awe. Seen from Nob Hill to the Embarcadero, the spectacle sparked both excitement and curiosity—lighting up not just the skies, but also social media feeds with questions like: “What’s the occasion?” and “Who’s behind this beautiful surprise?”
The answer? A landmark celebration by Computers and Structures, Inc. (CSI)—a global leader in structural and earthquake engineering software—as it marked its 50th anniversary in unforgettable fashion.
A Golden Milestone: CSI Turns 50
Founded in 1975, CSI has played a monumental role in shaping the skylines of cities across the globe. From earthquake-resilient infrastructure to iconic high-rise buildings, CSI’s software—like SAP2000, ETABS, and SAFE—has become the backbone of innovation for engineers and architects worldwide.
This year, the company celebrated five decades of technological excellence and global impact with a private event held at Pier 27 in San Francisco. The culmination of the night? A spectacular fireworks display over the bay—a poetic fusion of engineering precision and artistic flair.
Ashraf Habibullah: The Visionary Behind the Celebration
At the heart of CSI’s legacy is Ashraf Habibullah, its dynamic and visionary founder. For those who know him, the fireworks didn’t come as a surprise—it was quintessential Habibullah.
An icon in both technical and creative circles, Ashraf has long championed the idea that engineering is not just a science but an art form. His commitment to blending culture with code, analytics with artistry, and rigor with joy has defined his leadership style. Over the years, he’s hosted numerous events where engineering discussions shared the stage with music, dance, and visual storytelling.
The 50th anniversary celebration was no different—a private gathering of CSI colleagues, collaborators, and guests that honored the past while inspiring future innovation.
Community Reaction: A Mix of Wonder and Whiplash
While the fireworks mesmerized many, some San Francisco residents were understandably startled. With no prior public announcement, the sudden bursts of light and sound led to a flurry of reactions—from delighted surprise to puzzled concern. Social media buzzed with videos, questions, and light-hearted speculation.
The San Francisco Fire Department later confirmed that the fireworks were fully permitted and professionally managed, launched from a secure barge location. The confusion stemmed mainly from the private nature of the event and the lack of public notice.
CSI’s Lasting Impact on the World of Engineering
Beyond the night’s skyward display, CSI’s story is one of innovation, resilience, and global influence. Over the past 50 years, their software has helped design and safeguard critical structures in seismic zones, pushing forward both safety and creativity in architecture and infrastructure.
Ashraf’s vision has not only revolutionized how engineers work, but also how they think about their role in society—as creators, problem-solvers, and artists of the built world.
A Night to Remember—and Reflect
While the surprise fireworks may have temporarily mystified some, they ultimately served as a symbol of something bigger: a celebration of 50 years of engineering brilliance, cultural vibrancy, and the relentless pursuit of excellence.
San Francisco has seen many fireworks over the years—but few carried the meaning and message of this one.
