A Vision for Planetary Exploration
The Space Exploration Initiative (SEI) is the latest in a series of endeavors which represent humankind's desire to expand its knowledge and sphere of influence. Throughout recorded history,...
Application of Large Infrastructure Project Financing to Construction Projects in Space
In a time when space projects are limited by the scarcity of public funding it is reasonable to try to finance and operate them with the help of the private sector. An example to follow...
City and County of Denver Approach to Management Requirements
Construction of large infrastructure projects has become increasingly rare since the 1960's. In fact, America has not built a new airport since 1974. While sparse funding is certainly...
Nondestructive Testing of Concrete Elements and Structures
Quality of a concrete structure depends on good construction practice. On the other hand, continuous repair and maintenance preserve the quality of construction. Nondestructive evaluation...
A European Road Comes to the U.S.
From Sept. 7 to Sept. 22, a group of 21 federal and state transportation officials and industry representatives participated in the European Asphalt Study Tour, traveling the roads of...
Lunar-Based System to Supply Power to Earth: Summary of Concept, Benefits, and Development
The Lunar Power System (LPS) is described, references are given to other published work, and possibilities for demonstrating LPS are outlined. Analyses indicate that LPS can provide inexpensive...
On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....
Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...
The Evolution of an Environmental Monitor
After more than 40 years of planning, litigation, design and construction, one of the nation's most controversial highway projects is finished. The completion earlier this...
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....
