Replaced with a Replica
Nearly a decade ago, a 144-year-old covered bridge in Michigan was destroyed by arson. Its recently completed replacement was designed to look as identical as possible to the original structure while meeting...

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...

Learning From Pile Driving Failures: Out of Sight Can't be Out of Mind
The design of driven pile foundations for static service and strength limit state loading conditions is meaningless if the piles cannot be driven to the required depth and nominal resistance without sustaining...

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...

Resources to Enhance the Geotechnical Educational Experience
In 2016, I joined the ASCE Minnesota Section’s (ASCE-MN) inaugural infrastructure Report Card Committee at a time in my career when I was curious about the role civil engineering had to play in the overall...

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...

Space Place
To help design and construct human habitats for Earth orbit, the moon, and Mars, NASA is turning to teams of experts in academia and private industry, including civil and structural engineers. The ideas...

Micropiles Support the "Missing Link": Understanding Load Transfer in Challenging Subgrades
Authorized by Congress in 1944, the Foothills National Parkway partly traverses the foothills of the Great Smoky Mountains in Eastern Tennessee. Large sections of the parkway cross high ridges located...

Lava Tubes as Resilient Extraterrestrial Habitats: An Option For A Permanent Human Settlement Beyond Earth
The design, construction, and maintenance of safe and comfortable habitations are some of humankind’s oldest and most important activities. Millennia of experimentation and planning have led to earthly...

Arena of Books
The new Qatar National Library features a folded design with cantilevered corners on the exterior, while inside, an enormous single space for reading or socializing offers terraces stacked with bookshelves....

What Does the Crystal Ball Say? Energy and Water Issues Are Too Great to Ignore!
Over the past 15 years, the Geoprofessional Business Association's (GBA) Emerging Issues and Trends Committee has held a series of Crystal Ball Workshops (Workshops) to identify long-term emerging issues...

A Faculty Internship: Reconnecting with the Profession
After spending eight years as a full-time academic administrator at Lafayette College in Easton, PA – one of only a handful of institutions where discipline-specific engineering programs are embedded in...

Optimized Drilled Shaft Design through Post-Grouting: Shorten That Shaft for Better Performance
Tip post-grouting is a technique used to inject, under pressure, a neat cement grout beneath the base of a drilled shaft. This method enhances or improves axial load-displacement performance by increasing...

Geotechnical Delivery on Mega Transportation Projects: Challenges of Accelerated Delivery
Transportation projects have traditionally been delivered through the design-bid-build (DBB) delivery model, which continues to be the preferred method of delivering the majority of smaller and more traditional...

Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

Findings From a Joint Industry Study on Foundation Fixity of Jackup Units
During the design storm conditions the soil supporting jack-up unit footings may be close to, or at plastic failure. Accordingly, the use of elastic solutions to the problems of foundation...

Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...

Extreme Wave-Force Calculation Procedure for 20th Edition of API RP-2A
The paper describes the revised guideline design wave force calculation procedure approved for the 20th edition of the API-RP2A WSD and the first edition of the API-RP2A LRFD and contrasts...
