Book Description
Abstract: Visualized construction information may provide more impressive and interactive effects to information users. For construction operation designers and operators, enhanced visualization information may promote their skill and knowledge level and in turn elevate the performance of each individual operation they designed or operated in a construction project. Construction operations can be real-timely simulated with fully visualized computer graphics to convey users even more direct and effective construction information. However, the path for constructing fully visualized, dynamic and three-dimensional simulations for construction operations is not straightforward. Construction operation simulation is a program of an abstracted system to represent the key characteristics and properties of the real construction operation system. Therefore, a construction operation simulation system should be capable of at least generating virtual simulation environment, performing operational calculations and handling uncertainties of the represented system. This research proposes a system structure of simulation frameworks that provide approaches for constructing construction operation simulations that are real-timely visualized and three dimensional. This framework concept enhances the ideas of software modularity and reusability for facilitating creating complex applications. The proposed structure of simulation frameworks is consisted of three parts: the visualization framework, the modeling framework and the control modules framework. These three simulations frameworks, as their names suggest, in the simulation system will perform visualizing, model calculating and controlling tasks respectively. Outputs of these tasks combined enable the simulation to appear like real, operate like real and react like real. In the visualization framework, general models and methodologies in computer graphics for real-timely rendering simulation scene and graphical user interface are included. This framework is indeed the rendering power house that will promptly perform calculations in objects transformations, viewing transformation, generating lighting and textures, displaying simulation data, and providing interactive operation functions. The second simulation framework, the modeling framework, contains libraries and functions needed for simulation operation calculations. In this research, a rigid body physics engine is implemented and included as the main component of this framework. This physics engine can dynamically compute three dimensional motions and movements of rigid bodies simulated in the scene; and in turn calculate the corresponding reactions between rigid bodies if collisions occur. The third simulation framework, the control module framework, holds libraries and functions that enable the simulation system to better handle uncertainties and vagueness in the real situations. Due to the framework modularity and reusability, purpose-specific simulation applications can be created easily. Simulation applications can be created based on the need of specific study objective by just generating objects or retrieving needed functions from the three established simulation frameworks. Demonstrations of application examples are included in this research. The convenience and power of utilizing simulation frameworks in creating simulation application is also satisfactorily proved.

Book Description
Automated data collection, simulation and visualization can substantially enhance the process of designing, analysis, planning, and control of many engineering processes. In particular, managing processes that are dynamic in nature can significantly benefit from such techniques. Construction projects are good examples of such processes where a variety of equipment and resources constantly interact inside an evolving environment. Management of such settings requires a platform capable of providing decision-makers with updated information about the status of project entities and assisting site personnel making critical decisions under uncertainty. To this end, the current practice of using historical data or expert judgments as static inputs to create empirical formulations, bar chart schedules, and simulation networks to study project activities, resource operations, and the environment under which a project is taking place does not seem to offer reliable results. The presented research investigates the requirements and applicability of a data-driven modeling framework capable of collecting and analyzing real time field data from construction equipment. In the developed data collection scheme, a stream of real time data is continuously transferred to a data analysis module to calculate the input parameters required to create dynamic 3D visualizations of ongoing engineering activities, and update the contents of a discrete event simulation (DES) model representing the real engineering process. The generated data-driven simulation model is an effective tool for projecting future progress based on existing performance. Ultimately, the developed framework can be used by project decision-makers for short-term project planning and control since the resulting simulation and visualization are completely based on the latest status of project entities.

Book Description
Within the architecture, engineering, and construction (AEC) domain, simulation modeling is mainly used to facilitate decision-making by enabling the assessment of different operational plans and resource arrangements, that are otherwise difficult (if not impossible), expensive, or time consuming to be evaluated in real world settings. The accuracy of such models directly affects their reliability to serve as a basis for important decisions such as project completion time estimation and resource allocation. Compared to other industries, this is particularly important in construction and infrastructure projects due to the high resource costs and the societal impacts of these projects. Discrete event simulation (DES) is a decision making tool that can benefit the process of design, control, and management of construction operations. Despite recent advancements, most DES models used in construction are created during the early planning and design stage when the lack of factual information from the project prohibits the use of realistic data in simulation modeling. The resulting models, therefore, are often built using rigid (subjective) assumptions and design parameters (e.g. precedence logic, activity durations). In all such cases and in the absence of an inclusive methodology to incorporate real field data as the project evolves, modelers rely on information from previous projects (a.k.a. secondary data), expert judgments, and subjective assumptions to generate simulations to predict future performance. These and similar shortcomings have to a large extent limited the use of traditional DES tools to preliminary studies and long-term planning of construction projects.

Book Description
Urban spaces are being called upon to develop a capacity for resilience and sustainability in order to meet the major challenges they face. To achieve such a goal, a practical development framework must be implemented in order to take advantage of the technological innovations that characterize the field of construction and urban engineering. Today, multi-scale BIM is bringing about significant changes that are redefining the paradigms of urban management. It facilitates simulations of the sustainability of urban spaces with respect to several criteria; most notably relating to energy, the economy and the environment. Building Information Modeling for a Smart and Sustainable Urban Space proposes a theoretical and practical framework for implementing BIM models for the creation of sustainable and intelligent urban spaces. It addresses the issues of acquisition, modeling, interoperability, and BIM and GIS integration for the production of BIM models. Case studies are presented, providing a practical dimension that demonstrates the production process of the urban model and its contribution to multiscale simulations, particularly in real estate evaluation and urban renewal.

Book Description
This book introduces a planning support system called Strategic Spatial Plan Support System (SSP-SS) to visualize population growth and predict energy demand, land use, and waste discharge resulting from urbanization. By analyzing policy interactions between household agents, the book uses SSP-SS to visualize policy effects on urban areas during stages of growth and decline. Simulations are created based on these policy outcome assessments, taking into account the influences of energy and resource consumption on sustainable development in urban environments. The book is geared towards researchers, universities, and urban policy makers. The book begins by presenting a framework of urban growth simulation, and introducing SSP-SS. Then, household lifecycle and relocation models are employed for simulating policy impacts on urbanization, and investigating the impacts of spatial strategic planning. Several projects are assessed using agent-based modeling including shopping centre construction, day-care service for aging populations, and shelter accommodation capacities for earthquakes and other disasters. The final chapters discuss water and energy management, the environmental impacts of demand and consumption, and future recommendations for sustainable development and policy implementation. Introduces Strategic Spatial Plan Support System (SSP-SS) to visualize population growth and predict energy demand, land use, and waste discharge resulting from urbanization. Analyzes policy effects on urban areas during stages of growth and decline. Discusses the influences of water and gas consumption on environmental issues in urban areas for sustainable development.
