Power for Magma Electrolysis
This paper summarizes qualitative issues of electrical power distribution for near-term lunar facilities. The issues to be discussed were developed during a conceptual study of a Lunar...
A Prototype Model for Human/Automation Trade-offs
Future space construction missions will involve both human and machine constructors. Selection of the optimum constructor mix requires a model of constructor capabilities and requirements....
Hedratecture and Artificial Gravity
There is a need, according to the National Commission On Space, to develop three critical space facilities: A Space Base, A Variable-Gravity Research Facility, and a Lunar Surface Outpost....
Application of Statistical Distribution Theory to Launch-on-Time for Space Construction Logistic Support
The Center for Space Construction (CSC) has acquired historical launch vehicle data for analyzing space launch vehicle logistic support of space construction. This analysis will include...
DYCAM: A Computer Aided Engineering Tool for Space Construction Planning
Planning and management of construction activities in space have not received sufficient attention up to the present. Space Station Freedom, a number of large platforms and extraterrestrial...
The Selection of Constructors for Space Construction
The process of space construction is defined by the construction goal and by the construction system selected to accomplish that goal. The goal provides the tasks that must be executed,...
A Language Model for Space Construction Control
The optimal construction system for many space construction projects is a mixed construction ensemble. Such an ensemble consists of humans, robots with varying degrees of teleoperation...
A Cost Study of Concrete Production on the Moon
In proposing and evaluating a construction system for a lunar base, the question of cost would be the most important one. Although it is not possible to conduct a detailed cost study at...
Creatively Cost Sharing a Large Flood Control Dam
The passage of Public Law 99-662 in November of 1986, commonly known as the Water Resources Development Act of 1986, added a new dimension to Federal development of water resource projects....
Balancing Needs: Growth & Infrastructure Rehabilitation
Long range planning must include more than construction of facilities to meet new demands for service. A conscious effort must be made to balance the need for additional facilities with...
Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair a problem of cattails growing in the low flow portion...
Financing Small Water Supply Projects in Colorado
In order to meet the water supply needs of Colorado communities and the requirements of the Safe Drinking Water Act of 1986, the Colorado Water Resources and Power Development Authority...
Key Environmental Development Issues
Those in the business community who may be affected by environmental factors include: buyers and sellers of businesses, existing facilities, and real property; their lenders, brokers,...
Creede, Colorado?Channel Rehabilitation
The existing grouted stone channel in Creede, Colorado, is approaching the end of its useful life. The channel is subjected to repeated freeze-thaw cycles causing spalling of the grout...
Environmental Permitting a Major Expressway Facility in Florida
As general consultant to the Tampa-Hillsborough County Expressway Authority, Howard, Needles, Tammen and Bergendoff (HNTB) was responsible for the environmental permitting required for...
The Impact of the Morris Sheppard Dam Experience on Buttress Dam Safety Evaluations
The stability problems encountered at the Morris Sheppard Dam have had an impact upon the Federal Energy Regulatory Commission's (FERC) dam safety program. This paper describes...
Measuring Benefits of Water Supply Projects
Various approaches are used to determine the value of water supply projects. Deterministic methods will lead to biased valuation of additional supplies of water. Calculation of risk premium...
Marginal Cost Techniques for Reservoir Optimization
Selection of the optimum water supply reservoir from multiple reservoir sites under consideration in a water resource planning study for the Houston Metroplex evaluated hydrology, engineering,...
A Comparison of Two Reservoir Projects and Associated Fisheries Impacts
The evaluation of environmental impacts is a critical component of reservoir project development. Impacts to fisheries are especially significant because of the extensive alteration to...
Review of the Design, Construction, and Operation of the Lake Carolyn Flood Control Pump Station
A review of the design, construction, and initial operation of the Lake Carolyn Flood Control Pump Station in Irving, Texas is presented. Staged water resource development design concepts...
