Development of Improved 4D CAD System for Horizontal Works in Civil Engineering Projects
(American Society of Civil Engineers, 2013)One of the purposes of using four-dimensional (4D) computer-aided design (CAD) system is to express numeric construction schedule data into a visual format. While existing 4D CAD systems are appropriate for building projects ... -
Multiagent System to Simulate Risk-Allocation and Cost-Sharing Processes in Construction Projects
(American Society of Civil Engineers, 2013)Multiagent systems (MASs) consist of several autonomous entities, called agents, that interact with each other to either fulfill their own interests (competition) or reach a common goal (cooperation). In MASs, negotiation ... -
Reasoning about Building Systems and Content to Support Vulnerability Assessment in Building Emergencies
(American Society of Civil Engineers, 2013)Vulnerability assessment serves to identify vulnerabilities, develop responses, and drive the risk-management process. In identifying vulnerabilities, it is fundamental to identify and rank critical assets, which include ... -
Hybrid Stochastic Cellular Automata-Driver-Vehicle-Object Simulation Model for Heterogeneous Traffic at Urban Signalized Intersections
(American Society of Civil Engineers, 2013)The traffic flow at intersections is generally chaotic, and signalization is a control measure to reduce this chaos. Heterogeneous traffic at signalized intersections behave much differently from homogeneous traffic. Also, ... -
Reducing Bias and Uncertainty in Multievaluator Multicriterion Decision Making
(American Society of Civil Engineers, 2013)Many decisions are based on more than one criterion, judged by more than a single evaluator. Multievaluator multicriterion (MEMC) decision making can be controversial if bias or uncertainty find their way into the final ... -
Integration of Artificial Neural Networks with Radial Basis Function Interpolation in Earthfill Dam Seepage Modeling
(American Society of Civil Engineers, 2013)In this study, the radial basis function (RBF) spatial interpolation method was used to estimate the potential water heads through an earthen dam. The multiquadric (MQ) function was used to discretize the seepage governing ... -
Self-Adaptive Differential Evolution Algorithm Applied to Water Distribution System Optimization
(American Society of Civil Engineers, 2013)Differential evolution (DE) is a relatively new technique that has recently been used to optimize the design for water distribution systems (WDSs). Several parameters need to be determined in the use of DE, including ... -
Algorithms for Generating Three-Dimensional Aggregates and Asphalt Mixture Samples by the Discrete-Element Method
(American Society of Civil Engineers, 2013)An algorithm for generating three-dimensional aggregates was developed first in this study. This algorithm can model the various shapes, sizes, and angularity of coarse aggregates. The shapes, sizes, and angularity of the ... -
Automated Progress Monitoring Using Unordered Daily Construction Photographs and IFC-Based Building Information Models
(American Society of Civil Engineers, 2015)Accurate and efficient tracking, analysis and visualization of as-built (actual) status of buildings under construction are critical components of a successful project monitoring. Such information directly supports control ... -
Computer Program for Multimodel Reliability and Optimization Analysis
(American Society of Civil Engineers, 2013)A computer program is developed to carry out reliability and optimization analysis with many interconnected probabilistic models. The program is freely available online and it contains a library of versatile models. The ... -
Document Discourse for Managing Construction Project Documents
(American Society of Civil Engineers, 2013)Several important aspects characterize construction project documents. Large numbers of documents are produced in construction projects. The majority of the documents are unstructured textual documents. The production of ... -
Computational-Based Approach to Estimating Travel Demand in Large-Scale Microscopic Traffic Simulation Models
(American Society of Civil Engineers, 2013)The increased interest in the development and application of large-scale or regional microsimulation transportation models has brought to the forefront the challenges associated with estimating the dynamic demand information ... -
IFC-Based Framework to Move beyond Individual Building Elements toward Configuring a Higher Level of Prefabrication
(American Society of Civil Engineers, 2013)Prefabrication is a form of industrialization that transfers some stages of the construction project from fields to an off-site production facility. The most widely used form of prefabrication in construction is the use ... -
Three-Dimensional Simulation Parameters for 90° Open Channel Bend Flows
(American Society of Civil Engineers, 2013)Sharp open channel bend flows are highly three-dimensional because of the combined effects of secondary flow, large free-surface variations, and flow separation along the inner bend wall. A comprehensive analysis was ... -
Automated Real-Time Monitoring System to Measure Shift Production of Tunnel Construction Projects
(American Society of Civil Engineers, 2013)The productivity of a tunnel construction project can deviate from the predicted plan due to many factors, such as equipment failure, weather conditions and unexpected soil characteristics. Early detection of such deviations ... -
3D Visualization of Traffic-Induced Air Pollution Impacts of Urban Transport Schemes
(American Society of Civil Engineers, 2013)The negative impacts of urban traffic growth are well known, e.g., congestion, increased air pollution, and more traffic noise. Humans can readily see traffic congestion, and can hear traffic noise, but inevitably they are ... -
IFC-Based Product Catalog Formalization for Software Interoperability in the Construction Management Domain
(American Society of Civil Engineers, 2013)Interoperability of the heterogeneous applications used in the domain of construction management can be best achieved by using generalized and standardized representations of the needed product data together with the data ... -
Efficient Numerical Method in Second-Order Inelastic Analysis of Space Trusses
(American Society of Civil Engineers, 2013)In this paper, the Newton-Raphson method is combined with three different algorithms. These algorithms are the generalized minimum residual (GMRES), the least squares (LSQR), and the biconjugate gradient (BCG). Of these ... -
