Automated Vibration Monitoring for Construction Applications: A Retrospective and Current Practice or… Everything Is so Much Easier Now!
My career in vibration monitoring (VM) began in the late 1980s. At that time, the state of the practice was primarily focused on blasting operations, which was driven by a boom in highway construction...

Performance-Based Earthquake Engineering: What Can It Do for You?
There's been a lot of talk, and some confusion, lately about performance-based earthquake engineering (PBEE). Many geotechnical engineers wonder -- what is it, how does it differ from what I've been doing,...

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...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

Instrumentation and Monitoring
A detailed plan for monitoring possible ground surface movements caused by the microtunneling operations should be prepared. The plan is typically prepared by the engineer in consultation...

Hail Concepts
Hail, the product of vigorous deep convection, requires those same conditions that are conducive to the development of thunderstorms. These conditions include water vapor, especially in...

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...
