Interactive Cost Estimating During Design
This paper describes a model, called the Automated Interactive Cost Estimating System (AICES), which gives users access to reinforced concrete cost information that is sensitive to variations...
Practical Approach to Cope with Construction Cost Uncertainty in an Inflationary Environment
There are actions suggested to mitigate the risk in costs caused by an inflationary economy, such as escalation clauses and including price contingencies in the bid . This paper presents...
Influence of Spatially Random Soil Stiffness on Foundation Settlements
The effect of stochastic soil stiffness on the total settlement under the corner of a uniformly loaded flexible strip footing has been studied. The generated Young's modulus random fields...
Application of the Phase Change Process to One-Dimensinal Consolidation Behavior of Peat
In this study, based on the fact that the pore of fibrous peat consists of the macro (outer) pore between organic matters and the micro (inner) pore inside organic matter, an approximate...
Clarifier Enhancements Yield Excellent Performance
The critical role of final clarifiers in meeting effluent permit requirements in indisputable. Poor performance of the final clarification step may adversely affect effluent quality. Experience...
Optimization Studies of Anaerobic Expanded Bed Reactor Pretreatment of Domestic Wastewater
In recent years the advent of the anaerobic expanded bed reactor (AEBR) has made possible the treatment of wastewaters of comparatively lower strength than have traditionally been treated...
Removal of Arsenic by Enhanced Coagulation and Membrane Technology
The U.S. EPA is promulgating a new MCL for arsenic based on epidemiology studies. The concern from the water industry is that the new MCL will be significantly lower than the current MCL...
Low-Cost Bridge Scour Measurements
This paper reports on the use of a low-cost, highly portable sonar system. The ease of use of the instrument and the short time required to make measurements should make this system valuable...
The Inflation Equation
The authors, a Brazilian and an American involved in a US$1 billion-plus project to build schools in the state of Rio de Janeiro, discuss how they managed despite monthly inflation of...
Pregame Show
The 1996 Summer Olympics are still two years off, but Atlanta's painstaking preparation is in full swing. One key element is a carefully crafted construction program. The...
Civilian Structures: Taking the Defensive
The 1992 terrorist bombing of the World Trade Center in New York posed a challenging question to the engineering community: Can we design cost-effective structural systems for public and...
Alternative Habitat Concepts for the First Lunar Outpost
The First Lunar Outpost (FLO) Study was a NASA-wide effort to define systems for a near-term, low cost return to the Moon. The FLO habitat must support four crew on the lunar surface for...
A Microcomputer Model to Estimate the Benefits of Volume Generated Auxiliary Passing Lanes on Two-Lane, Two-Way Highways
Safety and operational characteristics of rural and suburban two-lane roadways can be substantially improved by the provision of adequate passing opportunity, especially as traffic volumes...
Optimal Cost Basis for Seismic Design
The paper summarizes a methodology for establishing seismic design levels based on a cost-benefit assessment. The methodology requires the development of costs and benefits for varying...
Systems Integration and Economic Aspects of the Universal Container System
Universal containers (UC) are multi-assembly spent fuel containers that are loaded and sealed at reactor sites or the first DOE facility. They are thereafter handled as clean containers...
Alternative Strategies?A Means for Saving Money and Time on the Yucca Mountain Project
The United States Department of Energy (DOE) is undertaking studies to determine the suitability of Yucca Mountain (YM) as a potential site for disposal of high-level nuclear waste. Yucca...
Non-Fuel Bearing Hardward Melting Technology
Battelle has developed a portable hardware melter concept that would allow spent fuel rod consolidation operations at commercial nuclear power plants to provide significantly more storage...
The Independent Cost Estimating Process
The United States Department of Energy (DOE) requires that an Independent Cost Estimate (ICE) be prepared for all Major Systems Acquisitions (MSAs); that is, projects or programs expected...
Nonmarket Economic Values for Salmon and Wildlife Resources
Until recently, resource economists primarily focused on measuring the direct net value of fish and wildlife resources, when analyzing management options. And the technical literature...
Glen Canyon: The Economic Costs
Revenues from power produced at Glen Canyon Dam are used to support Colorado River Storage Project (CRSP) purposes, to pay O&M costs, and to repay construction costs. Generation...
