Refinement of Cost Estimates with Artificial Neural Nets
An estimate should be refined for undefined items. Usually, contingency is added to cover any inadequacies in estimate basis definition and inadequacies in estimating methods and data....
Application of Pen Computing to Construction Inspection
This paper discusses one customized inspection software package which runs on a pen computer. This program provides a format that assures a fast and accurate inspection process....
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...
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...
Void Fraction Measurement Techniques for Gas-Liquid Bubbly Flows in Closed Conduits; A Literature Review
This paper provides a review of void fraction measuring techniques for gas-liquid bubbly flows in closed conduits with emphasis on the suitability of these methods for air-water bubbly...
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...
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...
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...
Estimating Maintenance Cost of Existing Stormwater Retention Ponds
The 280-acre Kensington Business Park includes 11 stormwater retention ponds that were also designed to provide aesthetic enhancement. Maintenance of these ponds became a concern when...
Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...
The Evolution of Conservation Rates in Phoenix, Arizona
Conservation or increasing block rates first implemented in Phoenix, Arizona in 1982 were reexamined by a three year study involving Water Department staff, a Citizen Rates Committee and...
Storage/Treatment Isoquants for CSO Control Planning
A quantitative procedure which identifies the technically efficient combinations of storage volume and treatment rate necessary to achieve various levels of combined sewer overflows (CSO)...
