The Need for Geotechnical Investigation
Knowledge of the subsurface conditions is needed to decide which type of foundation to use. In the discontinuous permafrost zone, some generalizations may be made about the location of...

Construction Speed and Existing Utilities

Firepower
The processes put in place by water utilities are designed with the quality of water normally received for treatment in mind. But the runoff from areas ravaged by fire can degrade that...

Fate of Nitrogen Compounds in Animal Waste Lagoons
This chapter examines the fate of nitrogen compounds in animal waste lagoons. Topics include nitrogen in animal waste lagoons; transformations and removal; and subsurface transport....

Advancing Under London
Bored tunnels account for more than 20 percent of the Channel Tunnel Rail Link, the high-speed rail line that will connect the Channel Tunnel with London upon its completion in 2007. In...

Loading Requirements for FRP Poles Utilized in other than Utility Line Applications

Safeguarding Water Utilities
Immediately after the September 11 terrorist attacks, many water and wastewater utilities adopted or expanded security measures. Now with many systems conducting or planning to conduct...

A Dam for a Dam
The General Electric (GE) Dam in Minneapolis, Minnesota, was more than a century old when it began leaking excessively in December 1998. Operations staff for the dam owner—the Minneapolis-based...

Update of ASCE Manuals and Reports on Engineering Practice No.74 Guidelines for Electrical Transmission Line Structural Loads
For many months there has been doubt that the latest version of ASCE Manuals and Reports on Engineering Practice No. 74. Guidelines for Electrical Transmission Line Structural Loading,...

Effect of Aluminum Compression on ACSR Conductor Sags at High Operating Temperatures
Deregulation and restructuring are sweeping the electric utility industry in the United States. As a result, many utility engineers are analyzing, re-rating, and upgrading their most critical...

Emphasis on Aesthetics
Architects and structural engineers joined forces to create a large, visually appealing chilled-water plant for high-profile site near the southern gateway to the University of Pennsylvania....

Improving the Process
By revamping its solids treatment system, the wastewater utility in Louisville, Kentucky, eliminated odors, created a potential source of new revenue, and saved millions of dollars in...

Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data
Development of the referenced Standard began in 1996. It is slated for publication in summer of 2002. The intent of this standard guideline is to present a system of classifying the quality...

Non-Destructive Excavating Around Pipelines and Challenging Conditions
Hydrovac technology provides engineers and contractors with a unique solution for non-destructive excavating around sensitive buried lines. As a non-mechanical excavating method, it is...

Fluid Flows and Reactive Chemical Transport in Variably Saturated Subsurface Media

Probabilistic Simplified and Detailed Subsurface Drainage Water Quality Modeling of Nitrate Leaching
A transparent uncertainty structure is derived for simplified and detailed conceptual nitrate leaching as a result of a probabilistic modelling procedure. The uncertainty structure consists...

Rediscovering the Lost City
Since 1994, Kenneth R. Wright, P.E., of Wright Water Engineers, in Denver, has been studying evidence of civil engineering at the ruins of Machu Picchu—an ancient Inca city in the Andes...

Tied by Water
Water utilities in the Puget Sound region of Washington State face strict water quality standards and increasing water demands. Because of the Endangered Species Act, they are also under...

Jet Grouting for Microtunneling and Shaft Construction in Highly Congested Utility Corridors

Team Development Through Feedback
