Airport Towers: A New Generation
Airport control towers are a unique building type with monumental significance, both for the cities that own and operate the airports, and for the FAA which owns and operates them. Airport...
So Much Pavement, So Little Time
At its most basic, pavement management requires taking inventory of a pavement network, doing a condition assessment, setting up a database, then synthesizing the data collected for an...
Infratechnologies: Tools For Innovation
Infratechnologies support the practices of construction over the whole life cycle of constructed facilities. They include technologies for developing and applying information, standards,...
Egypt's Real-Time Water Management
The challenge and complexity of efficiently managing the distribution of the 55 billion m that Egypt draws from the Nile every year has prompted the country's Ministry of...
Geosynthetics Conquer the Landfill Law
Los Angeles' last operating landfill is undergoing a major expansion using innovative materials in the liner system to overcome difficult site conditions. The design represents...
Overcoming the Woes of Worldwide Work
The author, a civil engineer based in Gibraltar, discusses a variety of pitfalls encountered in international practice, with case histories and lessons learned. They can be caused by differences...

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...
Experience with Beach Fill Equilibration and Recommended Design Guidelines
