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...
Purging the Plastics
A full-scale floating system designed to clean up the Great Pacific Garbage Patch for a fraction of the cost and time of traditional methods has been deployed....
Appraisal of Lightweight Moorings for Deep Water
This paper outlines the potential advantages of using lightweight fiber ropes for mooring floating production platforms. The influence of tether properties on mooring system response is discussed. It is...
Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...
Porous Asphalt and Permeable Friction Course Overlays
Porous asphalt typically consists of conventional warm mix asphalt (WMA) or hot mix asphalt (HMA) with significantly reduced fines resulting in an open-graded mixture that allows water...
Pervious Concrete
Pervious concrete consists of a hydraulic cementitious binding system combined with an open-graded aggregate to produce a rigid pavement with typically 15% to 25% interconnected void space....
Cost Considerations
Cost is an important consideration when comparing microtunneling with other construction methods. Direct costs should not be the only consideration. Microtunneling has other benefits that...
A Probabilistic Approach to Karstic Foundation Variability
Karst is a landscape formed in soluble rocks caused by movement of water that has become slightly acidic. Limestone, dolomite, and gypsum are vulnerable to these influences and may be...
Sudoku and Geotechnical Solutions: Lessons from a Parallel Universe of Limited Data
Geotechnical engineering relies on data to reduce risk. We infer, interpolate, and extrapolate based on often limited data with time and cost constraints also at work. Similarly, solving...

Overview of Damage
This section provides an overview of the damage caused by Hurricane Katrina and its ensuing costs....
Fast Track
The high-speed magnetic levitation rail is now in operation in Shanghai - the first of its kind in the world - demonstrates that this extraordinary technology can move people in a way...
Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...
Transformation
The site of a former wastewater treatment plant in western New York State is now home to a sprawling public works complex thanks to an inventive reuse scheme that consolidates public works...
Can Less Be More?
With its higher strength and improved performance characteristics, high-performance steel is indeed an alluring materials. Its cost, however, also is higher, a factor that cannot be ignored....
Repeat Performance
Working with a budget of $10 million, engineers designing a new high-rise residential structure in New York City had to find creative ways to control costs. One budget-saving idea was...
Stabilizing a Crater Rim
A geocell and geogrid reinforced soil slope concept was selected to stabilize approximately 120 m of eroding and unstable portions of the crater rim at the National Memorial Cemetery of...
Into the Tunnel
Technological advances in wind tunnel testing and computer-aided design programs are enabling engineers to create taller and more aesthetically interesting buildings than ever before....
The Economics of Beach Nourishment in Delaware
This study provides a detailed examination of the benefits of Delaware's ongoing nourishment program, and examines the incidence of benefits to those who live within and outside of the...
Application of the Texas A&M University (TAMU) Dredging Cost Model to Long Distance Transport
To develop intelligent decisions about moving sediment long distances to the coast from dams, the cost becomes a major factor. The cost will be a function of many factors including cleaning...
