Dispute Avoidance
Dispute avoidance is not something that begins at ground breaking. Dispute avoidance is not a technique that helps you resolve the inevitable problems that arise during construction. Dispute...
In-Service Durability Evaluation of Armourstone
A summary flow diagram for rock evaluation, general to all rock types and engineering applications of rock is introduced. It is then applied to armourstone. Increasing detail within this...
Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...
U.S. Experience With Armor-Stone Quality and Performance
In the past 30 years problems with deterioration and cracking of armor stone in the United States have been concentrated in northern regions, particularly around the Great Lakes. The explanation...
Problems With Armor-Stone Quality on Lakes Michigan, Huron, and Erie
The instances of deterioration of armor stone at coastal structures on the Great Lakes result from numerous distinct causes, both intrinsic and extrinsic. However, the proof of specific...
An Example of Rubble Mound Construction Procedures
The Gold Coast of Queensland, Australia, is in an exposed coastal zone that is now suffering from major problems with both the availability of suitable large rubble armour and its durability...
Producing Armourstone Within Aggregate Quarries
This paper discusses a series of full-scale trial blasts which was conducted in an aggregate producing quarry with the objective of improving yields of armourstone. The quantitative research...
Recent Experience With Armor Stone Cracking in the Buffalo District
Accelerated deterioration of large armor stone on the Cleveland East Breakwater, Cleveland, Ohio has resulted in the need for more intensive monitoring of the entire armor stone production...
Learning to Love NDT
Sometimes overblown claims and the practical limitations of early nondestructive tests for concrete have left many civil engineers leery of NDT methods. While some are aware that NDT has...
Staffing Up for a Major Program
A nine-member construction management section must pilot a $335 million, multi-project capital improvement program over the next five years. Should construction management duties automatically...
Making Teamwork Work
From consulting firms to steel workers, most work groups would benefit enormously from developing better teamwork, but making it happen isn't easy. Excerpts from
Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...
Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...
Project Management: Keys to Success
Successful construction projects can be traced to several key factors observed by the owner, the AE and the contractor. They include: 1) Goals and commitment of the managing partners agreed...
Performance-Based Evaluation of Lunar Base Construction Equipment and Methods
Existing literature regarding the selection of lunar base construction equipment and methods is heavily dependent upon qualitative measures for evaluation of equipment concepts. Selection...
Extraction of Potable Water from Urine for Space Applications
A regenerative technology capable of managing water and wastewater on-board long-term manned space platforms is essential if the Bush Administration's Space Exploration Initiative (SEI)...
A Systems Approach to Water Recycling Research
Because of the cost of Earth resupply, water recycling from wastewater is a critical enabling technology for long duration space missions. The need and the fact that water quality is not...
Developments of Modelling Software for Civil Engineers
The paper describes some of the recent problems in the development of software tools for civil engineers, especially software for hydrodynamic and water quality simulations for environmental...
Thirty Year Simulation of Chesapeake Bay Eutrophication
Eutrophication processes in Chesapeake Bay, 1959-1988, are simulated using a three-dimensional model package. Results link the volume of anoxic water to degree of stratification and to...
Model Development for Operational Use to Help Spill Combating and Sea Rescue
Based on twenty years' experience on flow velocity measurements, transport experiments and numerical modeling the three-dimensional (3D) models of water currents, transport and water quality...
