Jacking a prefabricated concrete arch through a railroad embankment to provide a new access ramp to the Don Valley Parkway in Toronto was done for the first time in North America. In September...
Chicago's Loop: A New Approach
Reconstruction of the Wells St. Viaduct cleaned up a dangerous area just north of Chicago's Loop by providing a structurally sound approach for CTW commuter trains and a column-free...
One Power Plant, Two Job Sites
In response to the lingering questions about energy, officials from Vidalia, La initiated a plan in 1977 to build a hydroelectric plant at a site 90 mi northwest of Baton Rouge, where...
A Doubling Design: Rochester's Expanding Airport
Few projects offer greater design challenges or pose more critical construction complexities than a new air passenger terminal, especially when that new terminal must be built on land...
Monitoring Vibration
Vibration monitoring for construction projects is increasing rapidly. Instrumentation for measuring structural response to blasting began in the mining industry with research by the U.S....

This paper presents an overview of various developments in materials technology and design procedures in the Western Hemisphere over the last 20 years. Some projections for anticipated...
Recent Advances in Structural Rehabilitation Techniques for Underground Sewer Pipelines
A great challenge for the coming years, if not decades, will be the repair, renovation and renewal of the existing sewerage systems in the Federal Republic of Germany in the interest of...
The NOVA SPAN Bridge System
The NOVA SPAN Bridge concept provides the basis for the design and construction of a new variant in the field of bridges and culverts which, in its performance and operation, incorporates...
Advances in Trenchless Sewer System Reconstruction
The new developments and refinements in trenchless reconstruction technologies now permit total sewer system rebuilding of collectors, interceptors, manholes, service laterals, and force...
Comprehensive Leak Detection Survey and Benefit/Cost Analysis
Fort Carson, Colorado was the site of a comprehensive leak detection investigation of the potable water system with the express purpose of quantifying the benefits to be derived by a military...
Whatever Happened to Long-Term Bridge Design?
The Chairman of the Board of one of the leading engineering firms in the nation ponders the future of American bridges. In today's designing of bridges, Thomas R. Kuesel points...
Whitfield Reservoir Inlet Outlet Pipeline
Alameda County Water District reports on the planning, design and construction of a 48-inch water main installed under modern urban circumstances. The location of the pipe and the construction...
Pipeline Design and Construction Using High Density Polyethylene (HDPE) Pipe
All pipelines and pipe materials must be designed and constructed to address the limitations of the pipe and fittings in order to insure acceptable performance of the line. Conventional...
Optimal Design of Water Transmission Mains
Capital cost for constructing a water transmission main includes cost of the pipeline and its associated installation costs. Also included in the capital cost is the cost of a pump station....
A Look Back in Time to Verify Life Cycle Cost Analyses
The proper engineering design of any hydraulic structure requires consideration of different but interrelated fields of: 1) Planning, 2) Hydrology, 3) Hydraulics, 4) Structural, 5) Installation,...
Life Cycle Cost Analysis Discount Rates and Inflation
Life Cycle Cost Analysis techniques are useful for comparing alternatives that have differing cash flows over the expected life of a project. The selection of an appropriate discount rate...
Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
