Meeting the Infrastructure Challenge of the 1980's
The future of the nation demands a solution to critical infrastructure problem. The public works facilities must be maintained, restored, and added to. The condition of these facilities...
On-Line Computerized Maintenance Management
Maintenance is the last cost saving frontier of scientific management. Top management has concentrated on production for generations, largely ignoring maintenance. The attitude of 'fix...
Strategic Planning for Infrastructure Redevelopment
Competition for the available resources needed to redevelop, operate, and maintain our nation's infrastructure requires innovative thinking. To make best use of these resources,...
Infrastructure Awareness: Successful Techniques
The need to rehabilitate and upgrade our infrastructure systems, specifically the systems of water supply and distribution, wastewater collection and treatment, bridges, highways and mass...
Constructibility of Arctic Offshore Structures
The costs of structures designed for Arctic Offshore Drilling and Production Platforms have reached extreme levels. A major component of the costs of such structures is their constructibility....
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
Operations Improvement through Product Evaluation
Transit Managers today are involved in a battle to maintain the quality of their systems. This paper takes a close look at several problems and then suggests a cure that can be effective...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
Cost Assessment of Construction Noise Control
The results of a series of studies have provided noise control engineers with a method to estimate off-site construction noise levels and the cost of reducing these to acceptable levels....
Cost-Effective Design of Practically Vibration-Free High-Technology Facilities
Advanced electro-optical equipment, such as that used in the production of integrated circuits, requires clean environments with extremely limited vibrations. Ground motions, personnel...
Is There Grit in Your Sludge?
Getting the grit out of municipal sludge can lower the total cost of operating a wastewater plant. Grit escalates maintenance costs and abrasive-laden sludge is costly to dispose of. Because...
Water Develoment Models for Contemporary Planning
A methodology for evaluating water planning alternatives was developed and applied to the Nebraska Platte River. The methodology involved a micro-computer based screening model and a multi-objective...
Pipe Network Optimization by Enumeration
The paper describes a procedure for the optimization of pipe networks which is executed entirely in the discrete pipe size/cost domain. The technique is based on exhaustive enumeration....
Practical Optimization of Looped Water Systems
This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...
Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...
Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
Land Treatment of Refinery Wastes
The authors discuss: waste characteristics; land treatment; and cost comparison with incineration....
