Cost Effectiveness and Incremental Cost Analyses for Environmental Planning
The objective of this paper is to present an approach for evaluating alternative plans for environmental restoration and mitigation. After discussing problems that currently preclude the...
Rapid Slope Monitoring
Use of inexpensive coaxial cable rather than inclinometers has cut the cost of monitoring slope movement at seven potential landslide sites in California. The method involved is called...
Boston Blockbuster
The Central Artery/Tunnel project in Boston is probably the single largest publicly-funded transportation project in the country at present. The total cost will be between $8 and $10 billion...
Underground Contracts for the 21st Century
Noting that support for the guidelines for underground construction put forth by ASCE's Underground Technology Council has been eroding, the author addresses current issues...
Budgets
Marketing budgets vary greatly from company to company. They will be much larger, when you calculate labor as a percentage of total marketing costs, for smaller firms than larger ones....
Project Quality
Quality means that you must listen to the client. You are not the last word, especially when it comes to the budget, the design fee, and the parameters of the project on which you are...
Project Completion
The project closeout or completion period is one of extreme importance. This is the time for final review of the plans and specifications and probable construction cost. All last-minute...
Beyond Water Witching
Ground-water exploration is usually an uncertain and expensive endeavor. Since late 1993, however, Golder Associates Inc., Redmond, Wash., has been working with time-domain electromagnetics...
Turning Down the Power
Traditionally, utilities have responded to demands for more power by simply increasing the energy supply. But this results in higher costs for both the supplier (in the form permitting,...
Specifying End Results
Quality of materials and workmanship directly influences the life of pavement, maintenance costs, levels of service and user costs. End result specifications (ERS) make a step towards...
Capping with Fiber Clay
Landfill-cap construction is expensive and often results in economic hardship, especially for small towns. Costs for conventional clay or geomembrane caps for municipal solid-waste landfills...
ASCE Salary Survey 1995
The 23rd biennial ASCE salary survey of the civil engineering profession conducted by the ASCE Committee on Employment Conditions during the first quarter of 1995 is presented. It consists...
A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...
Zero-Gravity Sports Centers
One of the uses that has been proposed for fully reusable launch vehicles is `space tourism', the making of short visits to low Earth orbit by fare-paying passengers. This seems to offer...
Resource Recovery Facilities for Earth Approaching Comets
Mankind's next large resource location may be off the planet. The facilities required for mining and material processing offer interesting concepts for the development of mankind's first...
Potential demand for passenger travel to orbit
In recent years the possibility of `space tourism', that is individual passenger travel to space on a commercial basis, has received increasing attention. The possibility of such an activity...
A Comparison of Propulsion Systems for Space Exploration
There are three promising propulsion systems that might be used for space missions: chemical, direct nuclear, and nuclear electric. Selecting the best system for a mission involves comparing...
Reducing the Long-Term Effects of Zero-Gravity
Maintaining the physical health of scientists has been a longstanding problem in space flight research. Several ideas have been proposed to solve this problem. These include creating artificial...
Future Launch Systems: The Policy Challenge
A review of the literature and discussions with military, commercial, and NASA representatives shows that all users agree we need new systems, but there is no agreement on which to pursue....
Spacecab: A Concept for Commercial Human Spaceflight
This paper will describe the Spacecab conceptual design and operational scenario. Spacecab is not necessarily a unique design solution but it does illustrate a design philosophy that differs...
