Designing Plans for Constructability
The writer has obtained several years experience acting as construction engineer for roadway rehabilitation projects as a consulting engineer. In this capacity, it is necessary to provide...

Constructability?Washington State Highways
During the last decade, efforts were directed towards improving constructability of highway design at Washington State Department of Transportation (WSDOT). This paper briefly summarizes...

Time/Cost Bidding
This paper presents the details of a relatively new and innovative approach to determining the low bidder on highway construction contracts. In the cost and time method each bidder proposes...

Coastal Sediments
This proceedings, Coastal Sediments '91, contains more than 180 full papers delivered at a specialty technical conference of the...

State and Local Issues in Transportation of Hazardous Waste Materials
Towards a National Strategy
This proceedings contains papers presented at the specialty conference State and Local Issues in Transportation of Hazardous Materials: Towards a National Strategy held on May 14-16, 1990...

Building Green
Some scientists say polystyrene insulation may be responsible for up to 40% of the ozone depletion caused by CFCs. That's only one reason why construction and design professionals...

The Effect of Surface Films on Concentration Fluctuations Close to a Gas/Liquid Interface
Modeling of gas/liquid mass transport requires knowledge concerning the behavior of near-surface concentration fluctuations at clean and film-covered gas/liquid interfaces. Previous measurements...

Hydrodynamics and Mass Transfer on a Moving Drop of Water
The fluid dynamics and mass transfer associated with moving water drops are examined. In the first part, numerical solution of the transient hydrodynamics around and inside a drop falling...

Correlation of Fractional Foam Coverage with Gas Transport Rates
Because breaking waves are believed to increase the flux of gases across the air/sea interface, it may be possible to correlate air/sea gas transport velocities with whitecap coverage....

Taller Tunnels
Between 1984 and 1991, Shannon & Wilson, Inc., Seattle, designed renovation programs for more than 25 mi of tunnels for four western railroads. We performed all of this work under...

Problems with Rock Excavation Specification in Alberta
As a result of contract overruns and claims from classification, measurement, and payment for 'solid rock' excavation, Alberta Transportation and Utilities embarked...

Where Does Rock Begin for Three Highway Projects?
'Where does rock begin?' was a question raised on three large highway projects in the western United States. The question was successfully answered by a variety...

Double-Decking the Freeways
Elevated highways cost more than at-grade construction. Nonetheless, the hidden costs of increased traffic congestion and the real cost of urban right-of-way make elevated highways feasible....

Civil Engineering Applications of Remote Sensing and Geographic Information Systems
This proceedings includes 41 of the papers presented at the Second National Specialty Conference on Civil Engineering Applications of Remote Sensing and Geographic Information Systems...

1991 OCEA Award Nominees
The $1.2 billion I-595/Port Everglades Expressway runs from Port Everglades to I-75, giving traffic a much quicker route from the Miami area to the Gulf Coast. It also links U.S. 1, I-95,...

Anatomy of Asphalt
Two main factors will combine over the next several years to alter the composition of asphalt pavements, which make up more than 90% of the paved roads in the U.S. First, a major research...

Plastic Highway Bridges
For highway bridges, composites are most effective in cables and decks. Researchers have developed and tested cables and deck sections for strength and fatigue resistance. Link-type cables...

Lifeline Earthquake Engineering?A New Zealand Perspective
This paper outlines the application of earthquake engineering to New Zealand's lifelines, tracing the development of design practices in roading, bridging, power generation...

Recent Advances in Seismic Design and Retrofit of California Bridges
This paper describes the damage and lessons learned from the most recent major earthquakes, the resulting bridge seismic design and detailing changes and the seismic retrofit program implemented...

Seismic Design and Performance of Railroad Bridges
Damage to railroad bridges during earthquakes in the United States and Japan is summarized. Research tasks are outlined to develop seismic design and retrofit criteria for railroad bridges....
