Developing a Training Program for Inspectors
The reasons for failure of engineering works are many and varied. An inexperienced or poorly trained construction inspector can be a contributing element in cases of failure. The Bureau...
A Lawyer's View of Engineers' Responsibility
When presented with a case involving damaged property, a lawyer typically will seek to determine the point of the failure and then work backwards in an effort to analyze each of the factors...
Probabilistic Approach to Maintenance Scheduling
Maintenance has the purpose of prolonging the working life of equipment and of sustaining expected levels of performance and reliability. If equipment deterioration is construed as a probabilistic...
Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...
Identification of Automation Opportunities
Construction, although the world's largest industry, is also its most archaic. Most construction practices are very labor-intensive, with resulting impacts on safety, productivity,...
Terrestrial Trends for Building Technology in North America
This paper discusses new building technologies that will develop in the early 1990's to become significant technologies by the mid 1990's. The perspective is...
Constraints on Lunar Base Construction
This article discusses the development of scenarios and designs for the construction of a lunar base or network of bases, which will require close attention to the natural and human constraints...
Lunar Resources: What is Known and Expected
The lunar regolith is the source of a number of basic materials which can be utilized in lunar construction. These materials include those which are obtained directly from the regolith...
Environmental Considerations for Lunar Base Engineering
