Rehabilitation of the CNW and ICG Railroads
The railroad industry is an indispensable part of the American economy. However, the railroad infrastructure was allowed to deteriorate to the extent of having 5. 4 billion in deferred...
Innovative Solution for Urban Freeway Reconstruction
Technology which was developed for economic and rapid construction of precast concrete segmental box girder bridges is being utilized to permit the reconstruction of an urban freeway in...
Golden Gate Bridge: Deck Replacement
A major inspection of the Golden Gate Bridge in 1968-69 found the reinforced concrete roadway of the Bridge to have widespread defects and local failures. Further investigations found...
Micros Go Afield
Taking microcomputers into the field is boosting productivity at construction sites and other field offices. Four examples presented in this article include an owner calculating payments...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
Structural Considerations for a Radwaste Facility
The structural engineer needs to consider several criteria when designing a radioactive-waste processing facility in order to properly balance the requirements of safety and economy. This...
Structural Retrofit for Nuclear Power Plants
Retrofitting of nuclear power plants is a major concern these days. Recent rulings of regulatory agencies have affected most of the generating plants in some way. The lessons learned from...
The 1984 novel
Project Management for the Upper Harlem Electrification Project
The Upper Harlem Electrification Project consists of a 28 mile extension of 700 V. D. C. under-running third (current carrying contact) rail electrification from North White Plains, New...
Finite Element Methods in Structural Safety Studies
The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method...
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),...
Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...
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...
Lift Bridge looks Like Sculpture
A lift bridge built in 1926 over the U.S. Canal at Kaukauna, Wis. was replaced by a sleek new lift bridge whose sculptured shape encloses all the machinery within welded steel box sections....
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
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...
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
Yakima Supervisory Real-Time Monitoring and Control System
The Yakima Remote Control System is a case study application of supervisory control and data acquisition (SCADA) concepts for the operation and monitoring of a large water resources project....
