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,...

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,...

Pay Now, Or Pay Later — Using A Risk-Informed Mindset for Site Investigation Decisions
How much subsurface investigation is adequate to aid in the planning and design of a construction project? It’s a question every geo-professional must grapple with, particularly in an era where cost efficiency...

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...

Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...

Site Conditions
The owner and the engineer should visit the proposed site during the initial planning phase and periodically throughout design to identify site conditions and constraints. A survey of...

Preliminary Geotechnical Considerations
In the planning phase of the project, a preliminary geotechnical investigation should be performed to identify the general subsurface conditions and any special subsurface conditions....

Microtunneling Design Elements
The design elements and the process for a microtunneling project are generally the same as for other underground projects. Design elements include the following: General conditions; Special...

The Joint Industry Development of a Recommended Practice for the Site Specific Assessment of Mobile Jackup Units
The mobile self-elevating (drilling) unit, or jack-up, has been central to the exploration and development of offshore oil and gas reserves. In recent years there has been an increased...

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,...

Detailed Site Investigations
This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...

A Light in the Deep: The Future of Offshore Site Investigations
For deep-water energy developments, hazard identification and risk assessments (that is, assessing the probability of occurrence along with the consequences of failure) are more important...

Is There a Movement Toward Three-dimensional Slope Stability Analyses?
Over the past few years, interest in performing three-dimensional (3-D) slope stability analyses has surged. An increasing number of research papers on this topic are being published at...

Design-Build and Public-Private Partnerships: Risk Allocation of Subsurface Conditions
Project Owners, especially in the public sector, are exploring and utilizing alternative project delivery methods, such as design-build (D-B) and public-private partnerships (P3s). Some...

The Best Surprise is No Surprise: The Geotechnical Engineer's Ethical Responsibility to Say No to Bidding
The subsurface characterization work that a geotechnical engineer must perform is critical to the success of every project that requires the cooperation of the ground, regardless of whether...

Karst-Related Sinkholes: Dynamic Compaction as an Effective Remediation Option
The paramount issue to address before constructing at sites underlain by karst topography is identification and remediation of sinkholes which exist close to the surface, and specifically...
