Waste Cleanup: Lessons Learned
Since hazardous waste mitigation is a new science, engineers need to pass on their experiences. The U. S. Army Waterways Experiment Station, seeking to expand the hazardous waste knowledge...
Opportunity Knocks from Behind Bars
As more and more lawbreakers are put behind bars, more and more prisons are needed, so the opportunities for civil engineers are expanding. Three major types of construction are being...
Get Involved with Cladding Design
Structural engineers should get involved with cladding design for their buildings. Including disclaimers for responsibility in the design contract will not prevent trouble or lawsuits,...
The Tunnel That Transformed Philadelphia
The 1985 Outstanding Civil Engineering Achievement is the Center City Commuter Rail Connection, a 1.7 mile tunnel connecting two former stub-end railroad stations in Philadelphia. The...
A Space Age Test Center
The Air Force's Aeropropulsion System Test Facility (ASTF) is the most expensive project the Air Force has ever built. Its massive heaters, coolers and compressors will treat...
Helms Pumped Storage Project
The powerhouse at California's Helms Pumped Storage Project is 1,200 ft below the surface of the Sierra Nevada mountains. Linking existing reservoirs, the project provides...
Record Bridge Replacement
Jacks Run Bridge had to be rebuilt in one year instead of the usual two to three. So the Pennsylvania Department of Transportation spearheaded the quickest replacement of a major bridge...
Who Should Design Bridges?
For many years Design-Build-Proposals have been common practice in Europe (except in the UK). Structures in these countries are 20% more economical than similar projects in the U. S.,...
Engineering Education: An Update
ASCE held an engineering education conference in April, 1985, entitled, Educators and Practitioners�Where Are We Going? Participants agreed that a greater interchange is beneficial between...
Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....
Effects of Vehicles on Buried, High-Pressure Pipe
The mechanical effects of selected types of traffic on buried, high-pressure steel pipe are examined. Particularly considered is a section of the Colorado Interstate Gas (CIG) pipeline...
Metal and Plastic Pipelines: Design and Construction Aspects
This paper discusses design and construction aspects of four cross-country pipelines that were built in central Alberta, Canada during 1982-1983. The first two pipelines, carrying different...
Successful Use of Trench Box in Sewer Line Construction
Faced with the problems of ever increasing construction costs, more and more methods are being employed in an attempt to keep expenses to a minimum without sacrificing the quality of construction...
Sewer Construction Inspection and Testing
Sewer construction testing is the final portion of the team effort that started with the goal of meeting the requirement for a sewer system for the protection of health and environment....
Unique Installation Methods for Large Interceptor in Poor Soil Conditions
The construction of approximately 1. 5 miles of a major sewer interceptor in downtown Boston encountered some unique construction challenges. The entire route required dewatering during...
Experiences in Concrete Pipeline Construction in Ontario 158-1985
The paper discusses the title subject in terms of concrete pipe fabrication methods and plants, pipe jointing and jointing materials, and construction experiences in the Province of Ontario,...
Alternative Approaches for Waterhammer Analysis and Pipeline Protection
This paper provides a brief review of typical waterhammer problems and their solutions for pumping systems. Alternative approaches to identify and resolve design problems are discussed....
Simplified Stress and Deformation Analysis for Pipeline Construction
This paper discusses the strength and deformation behavior of flexible steel pipes during pipeline construction. Some possible simple and quick solutions to these special design and construction...
A Study of Inlet Control Alternatives for SWM
A laboratory study of alternatives for effecting inlet control on urban storm sewer systems for stormwater management (SWM) is described. The test facility was a full-size physical model...
Field Testing of 84-Inch-Diameter Plastic Pipe
During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m)...
