Northwestern University’s Ryan Field: The NCAA’s Newest and Most Technically Advanced Football Stadium
Northwestern University and the Ryan family didn’t simply tear down and rebuild Ryan Field for their beloved Wildcats; they sought to create one of the best stadium experiences anywhere in the country. Built on the previous stadium’s footprint, it has 320,000 more square feet but 12,500 fewer seats, an intentional choice to make the fan experience more intimate and memorable. The design and engineering of this technically advanced steel structure was accomplished by Thornton Tomasetti, the multi...
LID Stormwater Engineering Transforms Mid-Century Indianapolis Neighborhood
The Norwaldo neighborhood on the northeast side of Indianapolis was primarily developed in the early to middle 20th century as the city developed along early streetcar and automobile routes. There was very limited stormwater infrastructure installed as it wasn’t needed at the time; most water was able to get to the surrounding streams and rivers naturally. But as impermeable development increased and storms became more frequent and released more water, water began to pond in low points on the st...
The Evolution of Hydrodemolition To Extend the Life of Concrete Structures
With increased demand to bring hydrodemolition to more applications, manufacturers engineer today’s machines to specialize in a wide range of concrete removal and repair jobs. In the early 1980s, the Swedish National Road Administration (SNRA) had a problem. The conventional way to repair a bridge was to remove concrete with jackhammers, but core samples on those projects revealed microcracks in the original parts of the structures. And, as it turned out, the consequences of those tiny cracks we...
New Walmart Campus Integrates Growing Community
The North Lake, one of two lakes on the Walmart Home Office campus, was engineered to store and manage stormwater. The design of the lakes allows for the controlled release of developed flow from the campus, prevents downstream flooding and minimizes the impact on two nearby creeks. (©Charles Yeager) The future looks bright for the city of Bentonville, Ark., following the new Walmart Home Office campus opening in spring 2025. The 355-acre open campus was designed to meet Walmart’s vision to prov...
Data Center Erosion Control: Hydraulically Applied Products Bring Solutions to Large-Footprint Problem
While history may be a haunting reminder of past mistakes, it paints a picture of consistency when focusing on technology. As the world continues to evolve and we, as a society, move into the future, technology continues to expand and grow. The latest hotbed of technological growth can be seen popping up in multiple areas domestically and internationally: the massive construction projects known as data centers. At the foundation of these construction wonders lie taxing demands made upon erosion...

How To Invest Best in Bridge and Road Infrastructure
Autonomous flying laser scanners capture structures and environments to create 3D point clouds while flying, allowing for the scanning of hard-to-reach places while offering a lightweight, easy-to-use experience. The Leica BLK2FLY uses omnidirectional radar and LiDAR to avoid obstacles for accurate, uninterrupted and safe scanning. The March 2024 collapse of Baltimore’s Francis Scott Key Bridge after a cargo ship crashed into it might be a turning point in how the country looks at its infrastruc...
Relief in Sight: South Florida’s Long-Awaited I-95/SW 10th Street Connector
This FDOT District Four project will enhance the safety and efficiency of the SW 10th Street and I-95 corridors as well as deliver congestion relief. (WSP in the U.S. rendering) For the team rebuilding the frustratingly congested Interstate 95 (I-95)/SW 10th Street corridor in Deerfield Beach, Fla., this is more than just another job: it’s definitely personal. “We all have encountered heavy traffic along this highway, and for some of us it’s a daily nuisance,” explains San...
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...
