Temperature Effects on Lasers
While lasers have markedly improved the accuracy of engineering, air temperature gradients can reduce that drastically. Based on a sewer project that used lasers to align all the pipe,...
High Tech Is More Than a Look
Hollow steel section, also known as tubular steel, is being used for its clean dramatic look, its structural efficiency in compression, the economic efficiency of combining structure and...
Arizona's Statewide Pavement Management System
A pavement management system developed for Arizon's 7400-mile network of highways has resulted in a savings of $14 million in its first year and a forecast savings of $101...
Coastal Structures '83
The objective of the conference Coastal Structures '83 was to develop in-depth discussion of the state-of-the-art and future needs concerning coastal structures. Design, construction,...
Geotechnical Practice in Offshore Engineering
The offshore industry as it exists today is just 30 years old. In that period the depth of water where structures are built has increased from a few feet to over 1000 feet. The performance...
Seismic Response of Buried Pipes and Structural Components
At nuclear power plants there are numerous underground safety-related pipes and structural components which are utilized in the operation of the plant. These underground components provide...
Innovations Cut Costs of a Power Plant's Water System
A two-unit (660 MW each) coal-fired power plant in St. Clair, MI, requires 660,000 gallons of water for condenser cooling. A once through cooling system from the St. Clair River (one mile...
Pavement Management Systems: Selecting Maintenance Priorities
Realization of the need to maintain a safe, serviceable network of highways in the US has led to the development of a systematic, consistent procedure for managing resources necessary...
Sewers: Repairing Beats Replacing
Rehabilitating decaying sewers can be up to 70% less costly than replacing them. Yet most sewerage agencies wait until a pipe collapses before taking action, necessitating expensive emergency...
Thaw Settlement Analysis for Buried Pipelines in Permafrost
This paper focuses on determination of allowable thaw settlement for the design of cross country pipelines in permafrost areas. The purpose of the thaw settlement evaluation is to aid...
Existing Sewer Evaluation and Rehabilitation
Guidlines for the evaluation and rehabilitation of sanitary sewers are presented. The purpose and scope of sanitary sewer rehabilitation is described. The major emphasis is on filtration...
Pipelines in Adverse Environments II
State of the art and future trends in pipeline design, construction and maintenance are reviewed. Specific areas addressed include adverse terrain conditions, river crossings-particularly...
World's Largest Installation of Fabric-Formed Pile Jackets
One major feature of fabric forming is permeability. One application of this technique is protective encasement of steel H and pipe piles at a major pier in Chile. The Huachipato Pier...
Sanitary Sewer Design
Good sanitary sewer design practice requires evaluation of alternative locations, slopes and pipe sizes. However, cost considerations generally keep alternative evaluations to a minimum....
What Type of Sewer Pipe is Best? Life-cycle Cost Analysis Yields Answer
In the past, many engineers have selected the type of sewer pipe for a particular project based mainly on a comparison of initial costs of concrete, steel, and other types of pipes. This...
Shanghai Tunnel Projects Spur Construction Innovations
Since underground construction in soft ground is newly developed in Shanghai, there is little experience there as compared to what is known for specific sites in other countires. Well...
