In the May 12 issue of Engineering News-Record, a compelling review of Michael M. Greenburg’s new book, The Great Miscalculation: The Race to Save New York City’s Citicorp Tower, revisits an important moment in structural engineering history. The book recounts how engineer William LeMessurier was alerted about a fatal flaw in his own design after construction was complete and occupied. His quiet behind-the-scenes response averted disaster. But now, Greenburg argues that a deeply fractured communication process between the design and construction teams magnified the originally flawed design.
Greenburg’s research underlines this gap, noting that “fragmented and disjointed construction processes” contributed to the oversight. Closer to home, we have the painful reminder of the Harmon Tower in Las Vegas (The Harmon – Wikipedia), which stands as another cautionary tale. These examples highlight why we must approach engineering differently. Direct involvement helps prevent costly misinterpretations, enables timely solutions when field conditions change, and protects the integrity of the design. It also fosters collaboration instead of conflict between designers and builders.
As The Great Miscalculation shows, engineering doesn’t stop when the drawings are signed. Our professional responsibility continues through construction—and ultimately, to the people who rely on the finished structure every day.
At Innova, when accepted by our clients, we offer Construction Observation—a service distinct from Construction Inspection. While inspection focuses on code compliance and quality control, observation ensures design continuity. It puts our engineers, those who understand the design intent, on site, supporting construction teams in real time. Construction Observation is how we bring our commitment to life: ensuring that projects meet their technical goals while delivering long-term value, safety, and trust.
It’s one of the many ways we aim to bridge the design-build divide. If you’re curious how this approach can benefit your next project, we’d love to talk.
