Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...
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....
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,...
Simplified Stress and Deformation Analysis for Pipeline Construction
