The Design of Hail Suppression Operations
When hail suppression operations are being considered, it is already understood that hail damage is a significant problem in an area in which the political subdivision, organization, or...

Conduct of Operational Hail Suppression Projects
Those conducting hail suppression operations should be vigilant and always prepared to react when potential hailstorms begin to develop. In this chapter, some guidance is provided for...

Evaluation of Hail Suppression Efforts
The rationale for conducting project evaluations is to find out how successful the operations are in achieving the desired results. This assessment is more easily said than done. It is...

Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....

Effective Stress Theory of Soil Compaction
The shape of the moisture-density curve obtained from compaction tests has been explained in terms of capillarity and lubrication, viscous water, and physico-chemical interactions. None...

Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...

Sustainable Development — A Geotechnical Perspective
Sustainability has become a key factor in major construction projects these days, and many geotechnical engineers have started focusing on the concept. Owners, public agencies, and the...

Enhanced Detection and Mapping of Buried Utilities—A Sustainability Perspective
The social and environmental impacts and benefits of projects make up the triple bottom line that represents a modern view of sustainable project development. Rather than considering only...

Managing Geotechnical Assets to Improve Highway System Performance
As geoprofessionals, we have a great opportunity to look at our work in new ways and to show its value to others. Highway agencies are looking to get the most from their assets and with...

Condition Indices, Performance Measures, and Managing Performance Data for Geotechnical Asset Management – Don't Get Buried!
Why don't transportation agency assets like pavements, bridges, and earthwork have a Check Engine light? Why can't you simply pull up the complete history and...

Asset Management of Earth Retaining Structures: Design through Design Life
Regarding new earth retaining structures (ERS) construction, the message is clear: plan for asset management. New construction is certainly not immune to performance issues, and the time...

Beer's Secret Ingredient: geology
As anyone in the beer business should know, water -- and what's in the water, courtesy of the geology through which it percolates -- can make all the difference in an end...

Risk-based Methods for Geotechnical Features in Transportation Asset Management
The purpose of asset management is to meet life cycle performance goals through the management of assets in the most cost-effective manner. In developing risk-based, asset management plans...

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...

The Transbay Transit Center: Breaking New Ground in Urban Geotechnics
A building boom centered around the construction of the new Transbay Transit Center (TTC) is transforming the South of Market neighborhood in downtown San Francisco, newly dubbed the Transbay...

Ground Freezing in a Congested Urban Area
Artificial ground freezing is a method of providing temporary earth support and ground water control for deep excavations and tunnels. The technique has been used for over 100 years in...

Challenges and Risks of Jet Grouting in a Congested Urban Environment
In the heart of London, one of Europe's largest jet grouting contracts is nearing completion. The jet grouting is part of the overall 7-year-long upgrade project to London...

Support of Excavation Challenges and Solutions at a Manhattan Excavation Site
This article discusses the challenges and alternate solutions encountered in 2012 during support of excavation operations at a medical center project site in Manhattan, NY. The project...

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...

Communicating Risk in Geotechnical Engineering Practice
Three project situations are articulated with specific emphasis on an element of uncertainty or risk unique to each....
