Comparing Probabilistic Methods for the Asset Management of Distributed Items
(American Society of Civil Engineers, 2005)Markov models have met with widespread success when used to determine asset management strategies for infrastructure systems such as pavements, bridges, and electricity and water networks. However other probabilistic models ... -
Pulling Loads for Polyethylene Pipes in Horizontal Directional Drilling: Theoretical Modeling and Parametric Study
(American Society of Civil Engineers, 2005)The paper presents an analytical study on the effect of borepath profile, borehole to pipe radius ratio, clearance between pipe and the borehole, and pipe stiffness on the behavior of pipes installed using horizontal ... -
Life Cycle Modeling of Concrete Bridge Design: Comparison of Engineered Cementitious Composite Link Slabs and Conventional Steel Expansion Joints
(American Society of Civil Engineers, 2005)Concrete infrastructure represents an enormous investment of materials, energy, and capital, and results in significant environmental burdens and social costs. There is an ongoing effort to identify material alternatives ... -
Infrastructure Interdependencies and Homeland Security
(American Society of Civil Engineers, 2005) -
Taxonomy for Outside Plant Construction in Telecommunication Infrastructure: Supporting Knowledge-Based Virtual Teaming
(American Society of Civil Engineers, 2005)With the expected volume of rehabilitation work in telecommunication infrastructures, there is a need to establish a means of supporting the exchange of project information in a semantic way. Semantic Web techniques provide ... -

Privatization of Municipal Services: Sustainability Issues of Production and Provision
(American Society of Civil Engineers, 2004)Privatization is an accepted strategy to improve the economic efficiency and quality of services provided by municipal infrastructure. However, the impact of using the private market to allocate public resources has not ... -
Fuzzy-Based Method to Evaluate Soil Corrosivity for Prediction of Water Main Deterioration
(American Society of Civil Engineers, 2004)A fuzzy-based method is proposed to evaluate soil corrosivity from soil properties such as soil resistivity, pH, redox potential, sulfide content, and soil type. The fuzzy-based method considers three levels of soil ... -

Soft Computing Applications in Infrastructure Management
(American Society of Civil Engineers, 2004)Infrastructure management decisions, such as condition assessment, performance prediction, needs analysis, prioritization, and optimization are often based on data that is uncertain, ambiguous, and incomplete and incorporate ... -
Life-Cycle Impact Analysis of Energy Systems for Buildings
(American Society of Civil Engineers, 2004)Cogeneration systems offer an opportunity to satisfy a building’s electrical and thermal loads, which could result in an overall energy efficiency improvement and lower environmental impact. Hourly energy simulation and a ... -
Life-Cycle Cost Award Algorithms for Design/Build Highway Pavement Projects
(American Society of Civil Engineers, 2004)The nation’s existing highway infrastructure was procured on a low-bid basis. The recent trend toward design/build delivery offers an opportunity to compete life-cycle considerations as part of the procurement. Minimizing ... -
Data Centers Revisited: Assessment of the Energy Impact of Retrofits and Technology Trends in a High-Density Computing Facility
(American Society of Civil Engineers, 2004)As information and communications technology matures, the nature of the infrastructure that supports it evolves and specializes. While the telephone infrastructure had been built as a network with central offices acting ... -
Minimizing Network Disruption for Planned and Emergency Repairs of Water Supply Systems
(American Society of Civil Engineers, 2004)Urban water supply systems are typically large, complex, and expensive to build and maintain. Disruptions of service can have serious implications on the economy, health, and convenience of those served by the system. ... -
Life-Cycle Energy Analysis of a Water Distribution System
(American Society of Civil Engineers, 2004)The paper presents a life-cycle energy analysis (LCEA) to quantify energy expenditures in the fabrication, use, and end-of-life stages of the pipes of a water distribution system. The methodology incorporates the capabilities ... -
Network Electricity Use Associated with Wireless Personal Digital Assistants
(American Society of Civil Engineers, 2004)This article examines the widely cited claim that the network electricity use associated with a wireless personal digital assistant (PDA) is equal to the electricity consumed by a refrigerator. It compiles estimates of the ... -

Greenhouse Gas Emissions from Coal Gasification Power Generation Systems
(American Society of Civil Engineers, 2004)Life-cycle assessments (LCAs) are computed for coal gasification-based electricity generation technologies for emissions of greenhouse gases (GHGs), principally -
Quantifying Effectiveness of Cathodic Protection in Water Mains: Theory
(American Society of Civil Engineers, 2004)Cathodic protection is a viable measure to extend the residual life of water mains and thus defer capital investments in their rehabilitation and renewal. The effectiveness of cathodic protection varies with the unique set ...
