Intelligent Geo-Construction Drilling Equipment: Delivering More Than Meets the Eye
The complexity, risk, and demands of engineered geo-structural projects have increased, seemingly exponentially, through the years. Physical and capital resources to deliver such projects, however, have...

From Good to Great: The Evolution of Cutoff Wall Quality Control and Verification Techniques
The last three decades have brought tremendous improvements to quality control (QC) procedures for construction and post-construction verification of deep cutoff walls installed in active high-hazard dams....

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,...

Recognizing Value in Site Characterization — How Cool Would That Be?

Your Numerical Model Begins at the Site Investigation — Phase Improving the Suitability of Numerical Geotechnical Modeling
The success of an advanced geotechnical numerical analysis depends foremost on a thorough geologic and geotechnical understanding of the site, and thus the geometric definition and adequacy of input parameters...

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,...
