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....
70 Years of Soil-Bentonite Slurry Walls: So, What's New
The soil-bentonite slurry wall (SBSW) is an established ground improvement technology that continues to find applications. It�s often the best and most economical vertical barrier to essentially stop lateral...
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,...
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...
Design of Shoreline Protection Measures : The Importance of Geotechnical Engineering in Waterfront Design
Over the past decade, there�s been an increased realization of the need to better protect our shorelines, particularly in urban environments along coastlines that have already been impacted by storm surge...
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...
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...
Seismic Performance of a Deep Soil Mixing Grid: A Magnitude 7.1 Load Test at the Port of Alaska
The Port of Alaska in Anchorage (Port) has embarked on a multiphase modernization program that includes the development of a new petroleum and cement terminal (PCT) berth. The berth consists of a pile-supported...
Building on Hudson Yards In Section: Megaproject Geotechnics: Can a Megaproject Be Big Enough to Change a Building Code?
As a young geotechnical consulting engineer working in New York City, I was always curious as to why the city?s building code prescribed a maximum allowable rock-socket skin-friction value of 200 psi for...
Megaproject Monitoring by Satellite ? InSAR-based Settlement-time History: Measuring Hundreds of Thousands of Points, Several Times a Month, Across an Entire City
Satellite-based interferometric synthetic aperture radar, or InSAR, has gained unequivocal importance as a routine and precise monitoring method for large and small areas alike. Historical datasets allow...
Subsurface Utility Engineering and Megaprojects: Avoiding Underground Conflicts Helps Speed Project Delivery
Experienced project owners realize that utility conflicts can be risky and pose unexpected impacts on the cost and delivery of projects, especially in urban settings. To help overcome these impacts, Subsurface...
Trenchless Goes Hybrid: Old Tricks Are Finding New Applications
The International Society for Trenchless Technology defines trenchless technology as "Underground construction methods of utility installation, rehabilitation, inspection, location and leak detection,...
The Best Laid Plans: Capitol Crossing Restores L?Enfant?s Vision of "Federal City"
In 1791, President Washington appointed French engineer Pierre Charles L?Enfant to plan Federal City ? today?s District of Columbia. L?Enfant?s methodical design called for the center of the city to be...
