CAD and the Corps
CAD has been a near standard feature of engineering design for the last decade, but the U.S. Army Corps of Engineers has found that the way their installations have gone about designing...
Highway Construction and a Trout Stream Relocation
In 1970, a ten-mile section of Traffic Route 15 in the northern portion of Lycoming County extending into Tioga County was under design as a two-lane limited access highway on four lane...
Urban Infrastructure: Our Crumbling POTW's
There is a need to address the problem of deferred maintenance at public owned treatment works. While specific data regarding the nations deferred maintenance bill is not available, we...
A Chance Constrained Optimization Model Using Kinematic Wave Routing for Stormwater Infrastructure Rehabilitation
A chance constrained optimization model is presented to determine efficient long-term replacement strategies for segments of stormwater drainage systems. The model is multiobjective in...
OCEA, American-Style
A truly All-American contingent, the nominees for this year's Outstanding Civil Engineering Achievement award span the continental U.S., Alaska and Hawaii. The scope of the...
Building Better Bridges: Concrete Vs. Steel
The authors debate the merits of concrete segmental and steel bridge design and construction based on five criteria: initial and life-cycle costs; structural advantages; durability; construction...
Design-Build Goes Public
Public owners of civil works get paid to avoid risk. It's their job. Why try some experimental technique for building offices when safe, proven methods exist? But times have...
The Role of Nondestructive Testing in Assessing the Infrastructure Crisis
At present the role of nondestructive testing in the evaluation of infrastructure deterioration is an extremely limited one. In the Author's experience this is, in part, due to a reluctance...
The SHRP-LTPP Asphalt Resilient Modulus Pilot Study
A SHRP asphalt concrete resilient modulus pilot study was initiated to provide important supplemental information related to the AC Mr program. Initially,...
Realistic Specifications for Steel Bridge Painting
Specifications play a vital role in a steel bridge painting contract. They not only can ease problems with painting construction, but can also provide a common standard for all parties...
Composites Performance in the Infrastructure
Fiberglass reinforced plastics (FRP) composites have been used in demanding structural applications, mostly for special corrosion resistant construction products, for several decades....
Earthquake Hazard Investigative Procedures for Central United States Waterworks
The vulnerability assessment of Central United States waterworks for earthquake hazards is a developing engineering practice for civil engineers in Arkansas, Missouri and states close...
Excavation and Support for the Urban Infrastructure
This proceedings,
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
Instrumenting the `Y'
Segmental bridges are still relatively new to the U.S. and questions persist about their design and behavior. To expand the knowledge base, a number of laboratory and field studies have...
Put to the Test
In the construction industry, the concept of life-cycle cost applies not only to the infrastructure itself, but to the materials that go in to building that infrastructure. To improve...
Minnesota Road Research Project - An Overview
The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research...
New Support for Pin-Hanger Bridges
To promote safety of their bridges, many state highway departments are considering ways to add auxiliary support to existing pin-hanger bridges. The Pennsylvania DOT and its open-end consultant...
Privatization Takes Flight
The number of air travelers in the U.S. is projected to double by early in the next century. Delays have also been mounting rapidly. Major airports around the world are facing the same...
Sustainable Energy Systems: A New Paradigm for New Energy Technologies
The fundamental links between energy production/use and the environment are becoming increasingly apparent. The major environmental challenges of global climate change, acid precipitation,...
