Abstract: Homeland security challenges civil engineers to develop solutions to protect critical infrastructure systems from intentional attacks. The water infrastructure system is one of eight critical infrastructures defined in the ...

Abstract: This paper describes a model developed for optimizing water supply plans for water customers when a water network is partially operational due to the destruction of water networks by malicious attacks or any catastrophic ...

Abstract: Transportation asset management (AM) research has yielded a well-accepted AM framework for state departments of transportation (DOTs) to model. However, no studies have developed a model to measure the level of AM ...

Abstract: Perhaps the greatest challenge facing the cost-estimating community over the next decade is the loss of knowledge and experience of highly experienced estimators because a high percentage of them are retiring, and a shortage ...

Abstract: Production rate estimation of major construction activities in a project play an important role in the planning of resources, tracking project progress, and determining contract time of construction projects as these ...

Abstract: Activity production rates drive the development and accuracy of linear schedules. The nature of linear projects dictates an assortment of variables that affect each activity’s production rate. The purpose of this research ...

Abstract: Accurate prediction of the current and future conditions of wastewater systems using available assessment data is crucial for developing appropriate proactive maintenance and rehabilitation strategies for an aging wastewater ...

Abstract: Subsurface utility engineering (SUE) is a fast growing industry segment in the civil engineering arena. Subsurface utility engineering is gaining credibility as a significant tool to reduce the risk from informational ...

Abstract: Although horizontal directional drilling (HDD) has been widely accepted and used for installing gas lines, waterlines, and telecommunication cables, its applications to gravity-flow sewer lines have been limited. One primary ...
