The Arch Bridge Mystery
For some years, concrete from the Manayunk Bridge�a long-idle, spandrel-arch railroad bridge in Philadelphia�had been spalling toward the streets and river below. While a system of nets...
A Joint Effort
In a public-private partnership that required close working relationships, a project that aimed to restore an old canal system� and its waterfront�in Richmond was combined with an effort...

High-Tech Highway
The Virginia Dept. of Transportation has spent more than $30 million on the first 2 miles (3.2 km) of the planned 5.7 mile (9.2 km) Smart Road near Roanoke, Virginia. Eventually the road...
Tall Order
Successive earthquakes have damaged the 32-story, 460 ft (140 m) tall Los Angeles City Hall, built in 1926. Masonry infill and concrete walls have cracked, and the terra cotta cladding...
GIS Paves the Way
The National Environmental Policy Act (NEPA) of 1969 requires an environmental impact assessment study for all Federal-aid transportation improvement projects. NEPA studies evaluate potential...
Predicting with Precision
In many urban areas flood prediction systems are inadequate. Most rely on networks of widely dispersed rain gauges that often fail to provide sufficient geographic coverage to characterize...
Easy Interface
Engineers have long desired to be able to move freely from computer-aided design (CAD) programs to geographic information systems (GIS) and their vast databases. Now, thanks to improvements...
Structural Design for Physical Security
State of the Practice
Prepared by the Task Committee on Structural Design for Physical Security of ASCE. This report provides guidance to structural engineers in the design...
Summary of Evaluation Findings for the Testing of Seismic Isolation and Energy Dissipating Devices
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of an evaluation...
Passage to 2000
On Dec. 31, 1999 the United States turns over ownership and operations of the Panama Canal Commission. In preparation for the handover, the Panama Canal Commission, an independent U.S....
Tracking the Temblor
The earthquake that occurred in Izmit, Turkey, in August 1999�along a fault line that is similar to the San Andreas Fault in Southern California�has provided useful data to researchers...
Learning from Disaster
After each earthquake, civil engineers learn more about what can be done to minimize the damage to infrastructure from seismic events. The recent large earthquakes that struck Izmit, Turkey,...
Topographic Surveying
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 29 This manual includes the new electronic surveying...
When the Levee Inflates
Rubber dams�long, flexible tubes, anchored to a concrete base and abutments and inflated with air or water�have been used since the 1950s, but installations have risen as technology has...
Defying Gravity
Vacuum sewers, a technology once used only in areas unsuitable for standard gravity sewer systems, are coming into mainstream use in highly developed areas as reliability improves and...
