Reliability of Crack Detection Methods for Baseline Condition Assessments
(American Society of Civil Engineers, 2010)Despite billions of dollars of annual exposure from claims and litigation related to construction-induced damage, there are no quantitatively based, agreed upon standards or procedures as to what constitutes due diligence ... -
Addressing Sustainability in Benchmarking Framework for Indian Urban Water Utilities
(American Society of Civil Engineers, 2010)Studies on benchmarking in water sector are very scarce particularly in the Asian region. None of the studies conducted so far have estimated and aggregated multidimensional performance of urban water utilities that ... -
Life-Cycle Perspective on Residential Water Conservation Strategies
(American Society of Civil Engineers, 2010)Motivated by the desire to understand the impact of water supply systems on the environment, a life cycle-based hybrid methodology is used to assess the performance of two conservation scenarios, water efficiency, and ... -
Comparative Assessment of Civil Infrastructure Network Performance under Probabilistic and Scenario Earthquakes
(American Society of Civil Engineers, 2010)The intensity of the seismic demand in a vulnerability assessment of an engineered system can be described in terms of either its annual probability of being exceeded or a scenario earthquake. A probabilistically stated ... -
Multicriteria Decision-Making Approach for Highway Slope Hazard Management
(American Society of Civil Engineers, 2010)Instability of roadway slopes and embankments is a type of geohazard that can endanger the traveling public and the nearby roadway facilities when large and sudden slope movement occurs. Frequently, the decision regarding ... -
Optimal Maintenance and Repair Policies under Nonlinear Preferences
(American Society of Civil Engineers, 2010)This paper is concerned with infrastructure maintenance and repair policies when the managing agency does not value expenses linearly. Such nonlinearity naturally arises in the stochastic world of reliability engineering, ... -
Methodology for Bayesian Belief Network Development to Facilitate Compliance with Water Quality Regulations
(American Society of Civil Engineers, 2010)Limited resources and drinking water quality requirements pose significant challenges to those managing small and rural drinking water distribution systems (WDSs). Real-time monitoring technologies could support regulatory ... -
Exploring Financial Decision-Making Approaches for Use in Earthquake Risk Decision Processes for Ports
(American Society of Civil Engineers, 2009)One of the main topics in the Georgia Tech/NEES Grand Challenge project “Seismic Risk Mitigation for Port Systems” is the evaluation of seismic risk management approaches for ports. One subtopic of this main topic is the ... -
Data and Modeling Issues Faced during the Efficiency Measurement of Road Maintenance Using Data Envelopment Analysis
(American Society of Civil Engineers, 2010)Within the past two decades, the road maintenance concept has been gaining tremendous attention. This has brought about new institutional changes, predominant of which is the challenge for maintenance managers to achieve ... -
Efficiency Measurement of Bridge Maintenance Using Data Envelopment Analysis
(American Society of Civil Engineers, 2010)A companion paper by the writers introduces the framework that was developed using an approach called data envelopment analysis to measure the overall efficiency of road maintenance operations while considering the effects ... -
Green Approach for Coping with the High Cost of Infrastructure Services in U.S. Colonias
(American Society of Civil Engineers, 2009)Colonias are unincorporated settlements along the U.S.-Mexican border. The lack of access to infrastructure systems combined with poor housing conditions has resulted in excessively high cost of electricity and heating and ... -
Rank Correlation Method for Evaluating Manual Pavement Distress Data Variability
(American Society of Civil Engineers, 2010)Evaluations of surface distresses in pavements, such as cracking, bleeding, and raveling, are often used as one component of overall pavement condition indexes. Both manual and automated survey methods are available for ... -
Estimating Infrastructure Condition from a Biased Sample
(American Society of Civil Engineers, 2009)In this paper, we address the problem of making inferences about a population of infrastructure facilities from a subset that is a biased sample. We consider the case in which the sample is biased toward facilities in worse ... -
Typology of Long-Term Port Efficiency Improvement Paths: Malmquist Total Factor Productivity forWorld Container Ports
(American Society of Civil Engineers, 2009)The global seaport sector made huge efforts in relation to port reform and technological development since the 1990s. This study attempts to systematically estimate the impacts of these efforts on world ports’ efficiency ... -
Uncertainty Analysis of Interdependencies in Dynamic Infrastructure Recovery: Applications in Risk-Based Decision Making
(American Society of Civil Engineers, 2009)The development of preparedness strategies for natural and malevolent man-made hazards and approaches with which to compare such investments is fraught with uncertainty. The dynamic inoperability input-output model (DIIM) ... -
Modeling Postearthquake Fire Ignitions Using Generalized Linear (Mixed) Models
(American Society of Civil Engineers, 2009)This paper presents a rigorous approach to statistical modeling of postearthquake fire ignitions and to data collection for such modeling and applies it to late 20th century California. Generalized linear and generalized ... -
Optimal Sampling of Infrastructure Condition: Motivation, Formulation, and Evaluation
(American Society of Civil Engineers, 2009)Infrastructure management is the process through which inspection, maintenance, and rehabilitation decisions are made to minimize total life-cycle cost. Condition measurement, spatial sampling, and forecasting introduce ... -
Energy and Greenhouse Gas Emissions Trade-Offs of Recycled Concrete Aggregate Use in Nonstructural Concrete: A North American Case Study
(American Society of Civil Engineers, 2009)The retirement of aging concrete infrastructure is resulting in significant material flows of concrete debris in the economy. A proposed outlet for this debris is new concrete: the debris can be crushed into small particles ... -
Structural Assessment and Upgrading of Sewers Based on Inspection Results
(American Society of Civil Engineers, 2009)A decision-support-system has been developed for the rehabilitation planning of sewers based on inspection results. The heart of the system is the structural reliability module that receives input on damage from inspections ... -
Building Infrastructure Functional Capacity Measurement Framework
(American Society of Civil Engineers, 2009)Building infrastructure “performance” is a term which describes the in-service functioning of a building for a specified use. The concept refers to how effectively, safely, and efficiently a building supports its mission ...
