Open Pit Geotechnics: Designing Slopes for a Very Deep Hole
For most hard rock surface mining operations, the development of an open pit is required to extract the ore resource. In designing an open pit, the challenge is to develop the most cost-effective pit slopes...

Redevelopment of Aggregate and Rock Quarries: No Longer Just a Hole in the Ground
Redevelopment of former sand and gravel (aggregate) and rock quarries can be challenging, often requiring developers, quarry operators, planners, and engineers to work in tandem. As urban and suburban...

A Place for Penguins
The Detroit Zoo’s Polk Penguin Conservation Center has created a habitat for Antarctic and subantarctic penguins designed to match their natural environment to the fullest extent possible. In addition...

Military Geotechnics in the Ancient World: Geo-Innovating the Hard Way
The technical expertise that is now part of geotechnical engineering was of paramount importance in the ancient worlds. This is because before, but also after, the invention of siege equipment, nearly...

Emergency Retaining Wall Replacement: The East 26th Street Slide Repair in Baltimore, MD
During a record rainfall on April 30, 2014, a century-old, stone retaining wall between a dense urban roadway (26th Street) and the CSXT railroad track in Baltimore, MD, failed. The stone retaining wall...

Geotechnical Risk Management: The Five Non-Technical Topics that are Crucial for the Successful Practice of Geotechnical Engineering
It is fair to state that the aspects of civil design and construction referred to as geotechnical engineering can be characterized as inherently risky. Geologic processes are complex,...

Engineering Iron and Stone: Understanding Structural Analysis and Design Methods of the Late 19th Century, By Thomas E. Boothby. Reston, Virginia: ASCE Press, 2015

Making Big Data Work for You and Your Project: A 3-D Geotechnical Model is a Smart Way to Work
Modeling the stratigraphy beneath a site and assigning soil and rock properties are important steps in geotechnical engineering. Geotechnical engineers often need to model ground conditions...

Geotechnical Design Over Karst. It's All About the Water
Karst is a type of topography which is formed over soluble rocks, such as limestone, dolomite, or gypsum. An irregular bedrock surface is typical of most karst areas, along with sinkholes,...

A Probabilistic Approach to Karstic Foundation Variability
Karst is a landscape formed in soluble rocks caused by movement of water that has become slightly acidic. Limestone, dolomite, and gypsum are vulnerable to these influences and may be...

So, Why Do You Want to Write a GBR?
Since 1974, scores of papers, articles, conferences, and legal documents have been dedicated to explaining how to write and/or how to use a Geotechnical Baseline Report (GBR). But the...

Improving Construction Quality by Seeing What's Hidden Underground
One of the challenges of deep foundation projects is the inability to see what's being built at depth. Construction is hidden below ground, in soil or rock conditions that...

An Innovative Plan is in the works to refloat and remove the cruise ship Costa Concordia, which foundered in the Mediterranean in January 2012 after striking a rock off the Italian island of Giglio...
