Assessment of Deteriorated Concrete Cover by Combined While-Drilling Techniques
(American Society of Civil Engineers, 2012)The assessment of concrete cover deterioration generally involves the analysis of cores taken from the structure. Nonetheless, monitoring the drilling operation is itself a way to scan the material condition at increasing ... -
Costs and Benefits of IEQ Improvements in LEED Office Buildings
(American Society of Civil Engineers, 2011)Costs and benefits resulting from improved indoor environmental quality (IEQ) in Leadership in Energy and Environmental Design (LEED)-certified buildings are often hypothesized; however, the precise quantification of such ... -
Dominance-Based Rough Set Approach to Budget Allocation in Highway Maintenance Activities
(American Society of Civil Engineers, 2011)This paper presents a decision-support system for the management of highway assets that uses a dominance-based rough set approach (DRSA). The decision concerns the allocation of maintenance funds among various highways ... -
Cost Structure and Efficiency of Korea’s Road and Rail in the Manufacturing Industries
(American Society of Civil Engineers, 2011)This paper analyzes the contribution of public infrastructure to private sector. It takes the example of road and rail and investigates their impact on South Korean manufacturing industries. To assess the cost structure ... -
Integrating WRc and CERIU Condition Assessment Models and Classification Protocols for Sewer Pipelines
(American Society of Civil Engineers, 2011)Adoption of a suitable sewer pipeline condition classification protocol is recognized as an indispensable first step in worldwide sewer rehabilitation industry. Various condition classification systems for sewers have been ... -
Guidance for Cost-Effective Selection of Pavement Marking Materials for Work Zones
(American Society of Civil Engineers, 2011)Pavement markings provide important information to motorists, especially in a work zone environment where alignments are often changed from what is typical. Unlike normal roadway applications, work zone pavement markings ... -
Modeling Uncertainties in Emergency Service Resource Allocation
(American Society of Civil Engineers, 2011)The problem of allocating multiple emergency service resources to protect critical transportation infrastructures is studied in this paper. Different modeling approaches, including deterministic, stochastic programming, ... -
Cost Functions for Australia’s Railways
(American Society of Civil Engineers, 2011)This paper utilizes a unique data set comprising almost hundred years of Australian railway history and applies the translog and symmetric generalized McFadden functional forms to the data in order to estimate cost functions ... -
Life-Cycle Optimization of Pavement Overlay Systems
(American Society of Civil Engineers, 2010)Preservation (maintenance and rehabilitation) strategy is the critical factor controlling pavement performance. A life-cycle optimization (LCO) model was developed to determine an optimal preservation strategy for a pavement ... -
Research Agenda for Transportation Infrastructure Preservation and Renewal: Conference Report

Postearthquake Recovery of a Water Distribution System: Discrete Event Simulation Using Colored Petri Nets
(American Society of Civil Engineers, 2011)Planning and preparedness is essential for any resilient infrastructure system. Modeling and simulation give engineers and planners a better understanding of the system and help them make better decisions. The objective ... -
Life-Cycle Assessment of Urban Water Provision: Tool and Case Study in California
(American Society of Civil Engineers, 2011)The exploration of life-cycle energy use and environmental effects from U.S. water infrastructure has been limited in spite of the strong connection between energy and water use. This research presents a methodology for ... -
Sewer Performance Reporting: Factors That Influence Blockages
(American Society of Civil Engineers, 2011)Managing sewer blockages represents a significant operational challenge for water utilities. In Australia, company-level blockage rates are used to compare the effectiveness of the management strategies of different ... -
Water Supply Performance and Fire Suppression during the World Trade Center Disaster
(American Society of Civil Engineers, 2010)This paper describes the New York City water supply performance and suppression of fire during the World Trade Center (WTC) disaster. The water losses sustained by damaged water distribution pipelines are discussed and ... -
Revisiting the Strengths and Limitations of Regulatory Contracts in Infrastructure Industries
(American Society of Civil Engineers, 2010)This paper evaluates regulation by contract in public-private partnerships (PPPs) in infrastructure services. Although the benefits of competition for the market and of regulatory contracts are widely acknowledged, the ... -
Risk Allocation in Public-Private Partnership Infrastructure Projects: Comparative Study
(American Society of Civil Engineers, 2010)It is important for the public and private sectors to establish effective risk allocation strategies for public-private partnership (PPP) projects in order to achieve a more efficient process of contract negotiation and ... -
Deterioration Forecasting Model with Multistage Weibull Hazard Functions
(American Society of Civil Engineers, 2010)In this paper, a time-dependent deterioration forecasting model is presented. In the model the deterioration process is described by transition probabilities, which are conditional upon actual in-service duration. The model ... -
Influence of Highway Project Characteristics on Contract Type Selection: Empirical Assessment
(American Society of Civil Engineers, 2010)The selection of appropriate type of contract for a highway maintenance project can be influenced by project attributes such as the expected cost and duration. However, the expected project cost and planned duration depend ... -
Preventing Sewer Blowouts during High-Velocity Jet Cleaning Operations
(American Society of Civil Engineers, 2010)The flow capacity of municipal sewer lines often diminishes over time due to root intrusion and debris accumulation. As a consequence, many wastewater agencies use high-velocity jets to scour sewer pipes and restore the ... -
Empirical Modeling of Pavement Overlay Crack Progression with Field Data
