Analyzing FRP’s Cost and Success in the Egyptian Theater Seismic-Retrofit Project
The Egyptian Theater was built in 1922, and its retrofit hoped to preserve as much of its history and aesthetic as possible while making it safe for a seismic event. The design-build field has continued to evolve and, as a result, various methods prove available to help engineers develop solutions to meet critical design criteria in an economically viable fashion. If the cost to produce the solution exceeds the budget, the engineer returns to the proverbial drawing board. A wave of i...
World’s Largest Wildlife Crossing Nears Completion in Southern California
The Wallis Annenberg Wildlife Crossing will span U.S. Highway 101 to connect the Santa Monica Mountains along the Pacific Ocean with the Sierra Madre Range to the north. (Rock Design Associates and National Wildlife Federation) The largest wildlife crossing in the world completed its first phase in June 2025, paving the way for restored ecosystem connectivity in the Los Angeles area. Sited among challenging terrain and over one of the busiest highways in the country, the Wallis Annenberg W...
When Routine Maintenance Finds Major Problems: Charleston Water System Turns Near Disaster into Opportunity
Because each half of the foldable isolation plug assembly weighed about 900 pounds, designers ended up installing manual cranks that could be used by divers when assembling. This photo was taken at the Petersen Products yard, where the dive team worked with designers to troubleshoot assembly procedure The Charleston Water System (CWS) Hanahan Water Treatment Plant set out to perform a normally routine maintenance task—take one 5-million-gallon clearwell (an approximately 220-foot-diameter...
Engineering Continuity: The EOR’s Role in Structural Steel Solutions for Historic and Architecturally Complex Renovations
A 3D model of the Pepco Mt. Vernon substation in Washington, D.C. (Extreme Steel Inc.) Historic renovations and architecturally ambitious retrofits walk a fine line between preservation and modernization. Whether it’s an adaptive reuse of a century-old mill or a new cultural landmark embedded in a dense urban grid, the challenges go far beyond aesthetics. Structural performance, code compliance, constructability and integration with existing materials all converge, requiring both technical...
A Glass Seawall in Florida Balances Function with Aesthetics
Venice, Fla., reconstructed its seawall using a glass floodwall. (City of Venice) Florida’s Gulf Coast is beloved by its residents and visitors, but its attractive shoreline can take a beating from severe weather events. In Venice, Fla., an existing seawall had reached the end of its useful life and needed to be replaced. During very high tides and large storms, water would overtop the seawall and flood the adjacent roadway, notes Christopher F. Kuzler, P.E., managing prin...
Country’s Largest Standalone Airport Terminal Set to Open at JFK
The 2.6-million-square-foot New Terminal One will be able to handle up to 20 million passengers per year when it opens fully in 2030. (Port Authority of New York and New Jersey) The New Terminal One (NTO) at John F. Kennedy International Airport (JFK) will accentuate a series of major airport improvements in the New York metropolitan area when it opens its first phase in June 2026, applying modern design and technology to support the area’s growing passenger, sustainability and resilience...
Responsible Adaptation: Navigating the Realities of Reuse on Campus
Macquarie University is building a dedicated multi-disciplinary building for engineering, astronomy and optics Universities are built to shape the future, but we can’t claim to be leaders if we act like nothing’s changed. In an era of climate urgency, how we use space says everything about who we are. In higher education, environmental responsibility isn’t a progressive stance: it’s the baseline. Institutions now measure carbon, set emissions targets, and embed sustainability into procu...
Unlocking Project Efficiency: Overcoming Industry Pain Points with PIM and BIM Integration
Disconnected data can be costly, but integrating BIM and PIM technologies helps eliminate errors and inefficiencies. You’ve probably felt it: the frustration of searching for a crucial RFI buried in an email thread or the anxiety that comes with not knowing if your team is working from the latest drawing. These aren’t just minor annoyances—they’re symptoms of a deeper problem in our industry: disconnected information. The solution isn’t just better software. It’s a smarter approach—one...
Concrete Research: Develops More-Sustainable Products and Working Conditions
MCDOT workers apply UHPC between slabs on the Palo Verde Bridge over the Roosevelt Canal in Buckeye, Ariz. While Arizona’s infrastructure may be younger than its East Coast counterparts, the effects of aging in a desert climate have begun to take a toll on its roads, bridges and railways. Repairs and replacements come with the challenges of traffic disruption, neighborhood inconvenience and high costs. In addition, concrete sustainability has become a critical goal for federal, stat...
