Transit Operations Input to Project Planning and Design
The rationale for most public transportation projects is a requirement imposed on the operating agency by an existing or expected service demand. These expected operations may be intended...
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
Assessing Seepage at Uncontrolled Hazardous Waste Sites
This paper presents a conceptual framework for estimating the concentration of organic contaminants in a groundwater plume over time. The basis of this framework is the application of...
Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
Noise Characteristics of Alternative Urban Transit Technologies
The noise characteristics of alternative transit technologies for an urban area are summarized. Among the transportation technologies considered are a busway system, light rail transit...
Summary of the Accomplishments of the Federal Rail Transit Vibration and Noise Control Technology Program
The U. S. Department of Transportation's Urban Mass Transportation Administration and Transportation Systems Center have played an active role in assisting the U. S. rail...
Noise Assessment, Measurement, and Mitigation, an OSHA View
A discussion is presented on the Occupational Safety and Health Administration (OSHA) 29 CFR 1910. 95 General Industry noise exposure standards and the 29 CFR 1926. 52 and 1926. 101 Construction...
Municipal Refuse: Is Burning Best?
Communities are increasingly worried about polluting groundwater, and it is increasingly difficult to get permits to start new landfills. For these reasons, there is a trend back to municipal...
Innovative Strategies to Improve Urban Transportation Performance
The field of urban transportation is facing some severe challenges. Roadways continue to deteriorate, the financial condition of public transit systems is abysmal, and general productivity...
Monitoring Saves a Site
A comparison is made of two supported excavations that were similarly designed and constructed. Both excavation support systems consisted of a soldier pile and lagging sheeting wall supported...
Organization and Management of Public Transport Projects
Transit development projects are undertaken to help satisfy escalating transportation needs in modern cities. The projects address an array of technical, social, and environmental considerations....
Rebuilding America
Infrastructure Rehabilitation
The future of the nation demands a solution to the problem of our deteriorating infrastructure. Civil engineers are called on to act as guardians of our public works facilities that must...
The National Ground Water Information Center Data Base
The Research Institute, Education Foundation and Publishing Company of the National Water Well Association have long been considered information central for the world's community of hydrogeologists....
Methodology of Determining Acceptable Levels of Heavy Metal Contamination in Municipal Sewage Sludge Applied to Cropland
The potential public health risks associated with the agricultural utilization of municipal sewage sludge dictate the development of environmentally acceptable criteria for the disposal...
Manatee County Plans for Environmental Protection
Faced with a projected population increase of 53 percent by the year 2000, Manatee County, Florida, is protecting its water resources by developing a regional wastewater facilities program...
Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
Integrated air samples were obtained at seven small and six large service stations and two dealerships. These establishments were sampled during cold and warm weather operations for eight...
Indoor Air Quality Simulations with the Mass Balance Model
Recent studies relate energy conservation measures, specifically to reduction of the air exchange rate of residences, with potential adverse health effects due to human exposure to increased...
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...
Emerging Environmental Clean-Up Responsibility
This paper is a summary of the structure of regulations requiring clean-up of sites when closed or sold, specifically the State of New Jersey's Environmental Cleanup Responsibility...
Age-Specific Cancer Risk Analysis for a Population Exposed to Contaminated Drinking Water
