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...
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...
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...
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...
Environmentally Friendly Transport of Reservoir Sediment for Beach Nourishment with EDDY Pump
Sand impounded behind hydroelectric, flood-control and debris dams not only diminishes the intended function of the reservoir, but also starves downstream coastline by denying natural...
Low Cost Sand Re-Nourishment to Combat Chronic Beach Erosion: Long Beach, California
The City of Long Beach has analyzed and attempted numerous methods of beach erosion control and mitigation along Peninsula Beach. With the exception of beach nourishment, nothing has proven...
Putting Down Roots
Phyto-covers are environmentally friendly and cost-efficient landfill barriers. Compared to traditional clay or geofabric caps, phyto-covers require less maintenance and are more friendly...
Use of Economic Optimization to Assess the Value of Water Marketing
(No paper) There is an increasing interest and implementation of water markets as an allocation mechanism for water in the Western U.S. However, the importance of the timing and location...
Optimization of the Aquifer Remediation Costs and Design with Pulsed Pumping
(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce...
