Holistic Strategy for Urban Security
(American Society of Civil Engineers, 2004)Since September 11, 2001, the vulnerabilities to terrorism of our urban areas, and how best to address them, have been subject to considerable discussion, debate, and reflexive defensive measures. Although direct physical ... -
State-of-Practice of Warranty Contracting in the United States
(American Society of Civil Engineers, 2004)This paper presents the results of a comprehensive survey on warranty practices in the United States and a summary of the impact of warranty implementation on highway projects, based on questionnaire responses and interviews ... -
Effectiveness of Ground Penetrating Radar in Predicting Deck Repair Quantities
(American Society of Civil Engineers, 2004)Ground penetrating radar (GPR) was examined as an alternative or supplement to visual inspection methods for predicting reinforced concrete bridge deck repairs. Visual inspection has frequently resulted in grossly inaccurate ... -
Development of Pavement Performance Models by Combining Experimental and Field Data
(American Society of Civil Engineers, 2004)The objective of this paper is to demonstrate the development of pavement performance models by combining experimental and field data. A two step approach was used. In the first step a riding quality model based on ... -
Economic and Environmental Evaluation of Residential Fixed Solar Photovoltaic Systems in the United States
(American Society of Civil Engineers, 2004)While the majority of electricity generated in the United States comes from fossil fuels such as coal and natural gas, a comparatively small amount comes from renewable sources such as solar and hydropower. As global ... -
Degradation of Drinking Water Treatment Plant Infrastructure from Enhanced Coagulation
(American Society of Civil Engineers, 2003)The new Enhanced Coagulation Rule requires that drinking water utilities improve the removal of natural organic matter from their water. One common method of doing so is to “enhance” the performance of existing coagulation ... -
Life-Cycle Environmental Effects of an Office Building
(American Society of Civil Engineers, 2003)This paper quantifies the significant environmental aspects of a new high-end office building over 50 years of service life. A comprehensive environmental life-cycle assessment—including data quality assessment—was conducted ... -
Optimal Fund-Allocation Analysis for Multidistrict Highway Agencies
(American Society of Civil Engineers, 2003)Allocation of funds for multidistrict highway agencies has traditionally been decided by the central administration based on predetermined criteria or formulas along with some consultation with regional agencies. In many ... -

Valuing Flexibility in Infrastructure Expansion
(American Society of Civil Engineers, 2003)Infrastructure facilities are generally heavy, fixed, and normally irreversible once construction has been completed. As existing facilities, they may confront economic competition of an increased space demand and the need ... -
Integrated Infrastructure Management Systems: Small Urban Area’s Experience
(American Society of Civil Engineers, 2003)Earlier management systems were typically developed to manage individual components of the transportation system. More recently, these systems have been evolving into integrated infrastructure management systems (IIMSs) ... -
Maintenance and Repair Decision Making for Infrastructure Facilities without a Deterioration Model
(American Society of Civil Engineers, 2004)In the existing approach to maintenance and repair decision making for infrastructure facilities, policy evaluation and policy selection are performed under the assumption that a perfect facility deterioration model is ... -
Highway Development Decision-Making under Uncertainty: A Real Options Approach
(American Society of Civil Engineers, 2004)A highway system development involves huge irreversible investments, and requires rigorous modeling and analysis before the implementation decision is made. This decision-making process is embedded with multiple uncertainties ... -
Adaptive Optimization of Infrastructure Maintenance and Inspection Decisions under Performance Model Uncertainty
(American Society of Civil Engineers, 2003)We present an adaptive optimization model to find joint inspection and maintenance policies for infrastructure facilities under performance model uncertainty. The objective in the formulation is to minimize the total ... -
Innovative Pavement Management and Planning System for Road Network of Portugal
(American Society of Civil Engineers, 2003)In this paper, the writers discuss the development of a comprehensive pavement management system and its implementation in Portugal. In the course of the development of this system, the writers addressed several issues ... -
Water Utility Security: Multiple Hazards and Multiple Barriers
(American Society of Civil Engineers, 2003)In recent years, the United States has learned much from natural disasters about risk to infrastructure systems, and now it faces new threats from malevolent attacks and other human-caused sources. The paper provides a ... -
Real-Time Monitoring for Quality Delivery of Directional Drilling Installations
(American Society of Civil Engineers, 2003)This paper presents an overview of quality management theory and its application in the area of trenchless technology in general, and horizontal directional drilling (HDD) in particular. Current practices that support ... -
Asset Management Framework for Geotechnical Infrastructure
(American Society of Civil Engineers, 2003)A significant limitation of current asset management systems is lack of consideration of geotechnical issues. This paper presents a simple framework for managing geotechnical facilities using asset management principles. ... -
Supply and Demand System Approach to Development of Bridge Management Strategies
(American Society of Civil Engineers, 2003)A supply and demand system approach is presented to deal with the inability of existing bridge management systems to determine optimal management strategies when multiple bridges may be adversely affected simultaneously. ... -
Infrastructure Issues for Cities—Countering Terrorist Threat
(American Society of Civil Engineers, 2003)Americans awoke on September 11, 2001, to watch a life and death struggle, live and in color, in New York and Washington D.C. but also to a changed world. We were shocked to realize we are no longer safe within our borders. ...
