Space Civil Engineering is an emerging engineering discipline that focuses on extending and expanding Civil Engineering to the development, operation, and maintenance of infrastructures...
A Vision for Planetary Exploration
The Space Exploration Initiative (SEI) is the latest in a series of endeavors which represent humankind's desire to expand its knowledge and sphere of influence. Throughout recorded history,...
Application of Large Infrastructure Project Financing to Construction Projects in Space
In a time when space projects are limited by the scarcity of public funding it is reasonable to try to finance and operate them with the help of the private sector. An example to follow...
Rocket Fuel to Earth Orbits from Near-Earth Asteroids and Comets
The analysis describes an architecture to bring 10,000 tons units of rocket fuel ore, propellant and construction mass back to low Earth orbit from newly discovered near-Earth comets or...
City and County of Denver Approach to Management Requirements
Construction of large infrastructure projects has become increasingly rare since the 1960's. In fact, America has not built a new airport since 1974. While sparse funding is certainly...
Nondestructive Testing of Concrete Elements and Structures
Quality of a concrete structure depends on good construction practice. On the other hand, continuous repair and maintenance preserve the quality of construction. Nondestructive evaluation...
A European Road Comes to the U.S.
From Sept. 7 to Sept. 22, a group of 21 federal and state transportation officials and industry representatives participated in the European Asphalt Study Tour, traveling the roads of...
Lunar-Based System to Supply Power to Earth: Summary of Concept, Benefits, and Development
The Lunar Power System (LPS) is described, references are given to other published work, and possibilities for demonstrating LPS are outlined. Analyses indicate that LPS can provide inexpensive...
Performance Specifications for the Design and Manufacture of Energy Efficient Housing in the 21st Century
This paper reports on work in progress in `Design for Energy Efficiency', one of fifteen task areas of the U.S. Department of Energy sponsored Energy Efficient Industrialized Housing research...
On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...
Hydrogeotechnical Considerations for the Disposal of Oil Shale Solid Waste Material
Laboratory tests and five large scale lysimeters (7.3?3.0?3.0 m deep) have been constructed to collect information and data on hydrogeotechnical factors which affect an oil shale solid...
The Evolution of an Environmental Monitor
After more than 40 years of planning, litigation, design and construction, one of the nation's most controversial highway projects is finished. The completion earlier this...
CAD and the Corps
CAD has been a near standard feature of engineering design for the last decade, but the U.S. Army Corps of Engineers has found that the way their installations have gone about designing...
