A Brief History of Jet Grouting in the Last 50 Years: The Story of Its Evolution
Jet grouting, a grouting soil improvement construction technique, was first developed in Japan in the 1960s and 1970s, and then introduced in Europe a few years later in the form of a proposal for soil...

Working Platforms for Specialty Geo-Construction
A major cause of rigs toppling over is the state of the "working platform" that they must work from. A working platform is a layer of material, often compacted sand or gravel, placed over the subgrade,...

When AI Meets DIGGS — The Birth of a New Site Characterization Paradigm?
Drilling and sampling to obtain borehole logs, together with various in-situ testing, are usually performed to determine subsurface soil and rock profiles and their associated engineering properties. However,...

Bring Your A-GaME! and Dominate the Field [Investigation] — As Newer Technologies Mature and Are Adopted More Widely — It’s A Whole New Ball Game Out There
The Federal Highway Administration (FHWA), in collaboration with industry partners, is helping state DOTs take their existing geotechnical site characterization programs to the next level. Technologies...

Practical Aspects Of Routine Geotechnical Site Investigations — They Should Be Anything But Boring!
It’s likely that on any given day there are hundreds of geotechnical site investigations in progress in North America alone. While many of these investigations are carried out in support of large projects,...

IoT and Big Data in Geotechnical Construction: Connecting Drill Rigs to the Cloud
It’s almost impossible these days to escape the fervor and buzz surrounding technologies and concepts such as Big Data, Internet of Things (IoT), Machine Learning (ML), and Artificial Intelligence (AI)....

Beyond the Water’s Edge: Geotechnics in the Wet
Gaining insight into the subsurface and developing an understanding of what’s hidden below ground is a key to the design and construction process. Geotechnical engineers and geologists often develop their...

Years of Planning for the South San Francisco Bay Shoreline Project: Now It’s Time to Build! Rapidly but Gently!
When a complicated project is completed, and you ask the engineers, "What was the most challenging part of this project?" a couple of difficulties usually come to mind. We’ve all heard war stories from...

Site Constraints Complicate a Bulkhead Replacement: It Takes a Team to Overcome the Challenges
North American Aggregates (NAA), a leading supplier of aggregates in the New York area, recently constructed a new processing facility in Perth Amboy, NJ. One of the final components of the new facility...

One Park, Many Functions
The Eastern Glades project in Houston has added a new artificial lake and other amenities to the city’s Memorial Park. As a highlight of the park’s 10-year master plan, the multifunction Hines Lake provides...

West Virginia’s Airport In The Clouds: Response to a Massive Slope Failure at Runway’s End
Although the small and scenic Mountain State ranked 40 out of 50 in population according to a July 2017 U.S. Census Bureau estimate, it boasts seven airports. Yeager Airport (CRW), billed as "West Virginia’s...

Seeing into the Subsurface: Harnessing Geophysics to Remotely Monitor the Condition of Earthworks
Condition assessment of geotechnical structures is essential for cost-effective maintenance and prevention of hazardous failure events. Early identification of deteriorating conditions generally allows...

Evaluating the Energy and Carbon of Geotechnical Works: An Important Step in Developing Sustainable Designs
Engineering for sustainable development requires considering the triple-bottom-line of social, economic, and environmental factors associated with a project when developing the final design. Within geotechnical...

The Pipeline to Diversity and Inclusion in the Geoprofessions: Challenging the Profession to Increase Innovation, Profitability, and Future Sustainability
Diversity + Inclusion (D+I) is a term often used in the workplace, but its meaning is not well understood. People generally value the concept, but its nebulousness has kneecapped the movement. In fact,...

Creating Art AND Reducing Project Risk WITH 3D Modeling: Digital Insights Unearth Hidden Landscapes
Humans have always lived in threedimensional space, with senses that evolved for a 3D environment. So, it’s perfectly natural that people can more quickly, easily, and fully understand something when it’s...

The Best Places For Civil Engineers 2020
ASCE’s Civil Engineering magazine researched and wrote this feature article before the widespread outbreak of COVID-19 and the subsequently declared pandemic in the United States. Since then, the health...

Back in Action
At one of Northern Virginia’s most complex and notoriously congested intersections, the superstructure of a critical highway overpass was demolished, removed, and replaced in a single weekend. The design’s...

Creating Copenhill
The design and construction of a new waste-to-energy plant in Copenhagen, Denmark, was meant to do more than just generate electricity. The unique structure also features a rooftop public park with an...
