TL;DR: In this paper, a comprehensive review on existing research on intelligent buildings is presented, which provides great benefits to identify where more efforts are needed and therefore the future research directions, which are useful to researchers working in this important area.

TL;DR: In this paper, the authors present a real-time control of on-site construction using the concept of measuring indirect parameters and converting them into the sought indicators, such as labor and earthmoving productivity.

TL;DR: Findings are presented from three research projects that made use of some of these techniques at various stages of the process: for collaborative working during concept design stage, for design development and marketing in the house building sector, and for the modeling of design details during the construction stage.

TL;DR: In this article, an agent-based framework for construction supply chain coordination is designed based on the agent technology and multiattribute negotiation and multattribute utility theory (MAUT) for construction.

TL;DR: This paper describes a preliminary integration of a generative structural design system, eifForm, and an associative modeling system, Generative Components, through the use of XML models to enable designers to readily develop meaningful input models.

TL;DR: The study aims at providing an alternative means for the RCPSP by utilizing the features of PSO, such as particle-updating mechanism that may benefit from the searching experience of one particle itself or the best of all particles in the swarm.

TL;DR: Markov-chain models are used for predicting the performance of infrastructure facilities because of their ability to capture the time-dependence and uncertainty of the deterioration process, maintenance operations, and initial condition, as well as their practicality for network level analysis.

TL;DR: This paper describes the designing grammar using Siza's houses at Malagueira as a case study and develops an interactive system for generating solutions on the Web based on a modeling approach called discursive grammar.

TL;DR: Experimental results indicate that the proposed system can minimize the amount of onsite material wastage.

TL;DR: In this paper, the authors extrapolate the analogical model of printing from the printed circuit to the printed plumbing core to the loadbearing service core, where the space is distributed between the served and serving areas, the latter being concentrated into a value-added factory-made module capable of generating diversified building types.

TL;DR: In this article, a 4D Integrated Site Planning System (4D-ISPS) is proposed to integrate schedules, 3D models, resources and site spaces together with 4D CAD technology to provide 4D graphical visualization capability for construction site planning.

TL;DR: In this paper, a scoring method for measuring the environmental performance committed by a contractor through calculating the contractor's environmental performance score (EPS) is presented. But the method is not suitable for the case of large-scale projects.

TL;DR: A new concept of “parts and packets unified architecture” is proposed, which is a unified controller system which operates parts and packets together.

TL;DR: An interactive speech and gesture recognition-based, immersive Augmented Reality (AR) model designed to visualize and interact with buildings and their thermal environments and the post-processed data are exported as Virtual Reality Modeling Language (VRML) models.

TL;DR: This paper presents the development and implementation of a new 4D planning tool which is a part of a product model-based project database and aims to contribute to what-if analysis in construction projects.

TL;DR: The previous development and implementation of a prototype four-dimensional site management model (4DSMM), with the objectives to address the requirement for linking scheduling data to a three-dimensional computer graphics building model and to furnish the capability for planners to view graphic simulations of the construction process at any prospective specified date.

TL;DR: The current implementation of the server system supports the automatic transformation of the design model contents and representations from the architectural domain to the structural domain, and remote visualization and interaction by Java applet and the Java3D technology.

TL;DR: The development of more refined process of construction management with the mobile computing device with personal digital assistants (PDA) on construction sites is indicated.

TL;DR: An experiment using a Web-based Virtual Environment (WbVE) that has improved a group of pre-service teachers' spatial ability understanding for teaching Engineering Drawing for secondary school subjects is presented and a discussion on the impact of WbVE spatial learning is discussed.

TL;DR: In this paper, the authors present a rigorous simulation-based optimization framework that enables concurrent and consistent decision-making in building design, which facilitates computational decision support for meeting building performance goals, allows autonomy of specialized design tasks with timely and efficient use of analysis tools.

TL;DR: In this paper, a model-based dynamic approach for construction resource management is proposed, where the dynamics of construction progress and the tradeoff with resource coverage are identified, and the dynamic resource management model that has been developed using system dynamics is described.

TL;DR: The long-term aim of the work presented in this paper is to develop a modelling and simulation platform, which will provide an inexpensive and risk-free environment for organisations to experiment with emerging SCM practices prior to implementation.

TL;DR: In this article, qualitative relations between the experience of architectural spaces and physical properties were investigated using virtual reality (VR) simulations, and a set of five widely independent factors (openness, two room proportions, room area, and balustrade height) turned out to be most effective for describing the observed variance in attributed experiential qualities.

TL;DR: The work described in this article deals with the development of a particular security system, using both existing commercial technology and specially designed equipment for modern construction systems where workers and automated/semiautomated machines coexist.

TL;DR: In this article, a questionnaire survey was undertaken to examine the approaches used by construction organizations to evaluate and justify their IT investments, and the analysis of 126 responses revealed the following key findings: different types of organizations significantly differ in the amount they investment in IT; investment levels in IT were not influenced by organizational size; and the scope of purpose of ex-ante IT evaluation was considered broader than a financial control mechanism.

TL;DR: In this article, a construction robot with pneumatic actuator and servo motor is used to attach a window glass mounting or panel fixing, and the sliding mode controller is adequate to such a cylinder that is strong nonlinear property.

TL;DR: In this paper, the authors explore the implications of what we know so far about the cognitive processes involved in the human design process and outline some of the sub-systems we will need in order to develop true comprehensive computer-aided architectural design.

TL;DR: Characterizations of generative tools and methods are described as a means of determining appropriate pedagogical tools in computer-based generative design tools.

TL;DR: In this paper, the authors present the findings of a number of workshops focussing on the problems and barriers inherent in the industry which would currently prevent effective implementation of a process improvement tool.

TL;DR: A multiagent system is developed to connect the virtual world to a central repository for storing the representation of the relevant data model and can be extended to the integration of other applications and data models.
