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,...

Preserving the Past: Recovering the Destroyed Buddha Statues and Niches in Bamiyan Afghanistan
For millennia, civilizations have built monuments to honor their gods, leaders, or founding principles, and with time those monuments that still exist have become revered treasures. Take, for example,...

State of the Practice for Laboratory Testing of Soft Soils: It's All in the Details
As with all material testing, soils testing has undergone dramatic advances in technology because of computer automation. In the 1970s, laboratories were filled with dial gages, proving rings, mercury...

As I See It: Rethinking the One-Third Increase in Bearing Capacity for Seismic and Wind

Low-Gravity Experiments: Shear Testing Takes a Nose Dive
A major challenge to making celestial soil mechanics viable is to re-engineer the profession's toolkit to provide geotechnical solutions without the luxury of ex-situ and in-situ testing as we know them...

Guidelines for Construction Vibrations: How Much Rattle is Too Much?
The study of construction/blast-related ground vibrations on structures, people, and objects is a surprisingly diverse field. Vibration sources vary from blasting, all types of construction equipment,...

Seismic Data from Smartphones: MyShake: Building a Global Smartphone Seismic Network
Increasing the density of earthquake-monitoring instruments at a fast rate and at a low cost is a dream for many researchers who study earthquakes. MyShake, a smartphone application developed by the Berkeley...

Claims against Geotechnical Engineers: Getting it Right in the Midst of Uncertainty
Geotechnical engineering is one of engineering's riskiest professions, prone to litigation due to the inherent uncertainty associated with characterizing the subsurface. Site investigations rarely provide...
