The MK II Art System?A New Generation of Automated Guideway Transit
Bombardier is well advanced in a program to produce a larger version of its successful Advanced Light Rapid Transit (ALRT) vehicle which is in service in Detroit, Scarborough (Toronto)...
Keeping the Books: A Taxing Task
Keeping two sets of financial books used to be considered a criminal act. Now it may mean survival for building contractors. Construction contractors are faced with the challenge of following...
The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...
Economic Factors in Roller Compacted Concrete Dam Construction
This paper deals with some of the economic factors that designers and contractors need to consider in the design and execution of an RCC dam. Costs for the RCC portion of the Upper Stillwater...
Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the corps of Engineers' requirement for economic justification. The costs of these measures are much greater than the benefits...
Design Considerations for Small Artificial Islands in Franks Tract, California
Small, artificially-created islands may provide significant recreation and habitat benefits. Costs, however, can also be high. The initial dollar cost of creating an artificial island,...
Value Engineering in Coastal Design
A formal procedure of value engineering can be applied to coastal design to refine a design and reduce the construction costs. Despite the relatively simple technology and materials used...
Cost Effective Risk Allocation for Coastal Engineering Projects
Project participants will benefit significantly by routinely taking a more systematic, structured, and global view of risk than is sometimes done at present. Enhanced and broadened cognizance...
Reassessing the Risk Assessment
Risk assessments should help an engineer determine cost-effective remedies to environmental pollution. Unfortunately, most don't. Most assessments drastically overestimate...
Landfills: Anatomy of Automated Design
California's 360 acre Bee Canyon landfill (completed last year) sits amid a complicated network of narrow canyons with side slopes 300 ft high. As with most landfill projects,...
Value Engineering at a Superfund Site
The Helen Kramer Landfill ranked fourth on the EPA's National Priorities List and the estimated cost of clean up was about $39 million. By value engineering selected parts...
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...
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Enhancing Decision Analysis Techniques for Lunar Base Construction Research
The usefulness of decision analysis concepts applied to lunar base construction research has been demonstrated [Boles 1990]. During the referenced work the authors realized that further...
A Proposed Methodology for Ranking Space Resource Utilization Processes
A recent survey paper on lunar manufacturing identified 26 initial steps previously proposed as primary routes for lunar processing. Most of these have not been studied in sufficient detail...
Materials and Structures Synergistic with In-Space Materials Utilization
The objective of this paper is to clearly demonstrate the significant advances made in recent months toward actual hardware realizations of various concepts for the utilization of in-space...
Cargo Transport to the Lunar Surface Using a Three Rotor Sling
The three rotor sling, a momentum transfer device, is described. The dynamics of multi-rotor systems are explained, and the three rotor system is shown to be favored over one and two rotor...
Extraterrestrial Resources: A Perspective from Terrestrial Economic Geology
Terrestrial mining experience indicates that the overwhelming criterion of a potentially economic deposit is its recoverable concentration of the desired mineral or element. These criteria...
Lunar Mining?Surface vs. in Situ?A Comparative Study
Surface mining and in situ mining are briefly reviewed and compared. It is verified that the inherent advantages of in situ mining over surface ruining point out that in situ mining should...
A New Era in Space Operations
The United States has embarked on a bold new course in space. We are in the process of deploying global missile defenses which promises to help realize an extended era of international...
