TL;DR: In this paper, the authors present a computer model which not only simulates the thermal performance of the building taking into account design variables related to the building's envelope and fabric, but also applies numerical optimization techniques to automatically determine the optimum design variables which achieve the best thermal comfort conditions.

TL;DR: The development and implementation of a collaborative working environment for construction at the University of Salford which is known as Web-based IFC Shared Project EnviRonment (WISPER), based on a three tier architecture, provides great flexibility and portability.

TL;DR: This paper presents a framework for the development of Facilities Management Classes and computer-integrated facilities management systems, including objectives, methodologies, implementation issues, etc.

TL;DR: In this article, a real-time kinematic (RTK) global positioning system (GPS) sensor was used to evaluate the vertical accuracy of road construction equipment under work site conditions.

TL;DR: The objective of NIST research is to make measurements required in a construction project quicker and cheaper than current practice and to do so without impacting existing operations by developing techniques for real-time assessment and documentation in terms of 3-D as-built models of the construction process.

TL;DR: Digital Clay as discussed by the authors is a sketch recognition program that interprets gestural and abstracted projection drawings and constructs appropriate 3D digital models for modeling and rendering applications in the design process.

TL;DR: The central part of the paper is devoted to the main technical innovations that have been developed in the frame of the project: universal vector database for road equipment guidance, multi-machine functionalities of CIRCOM and the two positioning systems which are actually the technological keys of the systems.

TL;DR: An all-weather automated construction system has been developed to reduce the total cost of high-rise reinforced concrete building construction as mentioned in this paper, which was applied for the first time ever to the construction of a 26-story reinforced concrete condominium project located in the Tokyo Metropolitan area in 1995.

TL;DR: The construction industry demands a productivity increase that cannot be attained by means of traditional methods for masonry that have already reached their system limits and cannot contribute to further effectiveness, so a certain innovative leap is required by a system approach that combines the already existing construction technologies with new information, automation and robot technologies.

TL;DR: In this paper, a 4-DOF Robotic bridge maintenance system (RBMS) developed by the Construction Automation and Robotics Laboratory (CARL) at North Carolina State University (NCSU) is described.

TL;DR: In this paper, an experimental approach to design collaboration, tested in an intensive, one-week long Virtual Design Studio exercise involving three academic institutions, is described, along with the resulting process of collaboration and lessons learned.

TL;DR: The concept of space is analyzed and a comprehensive definition for the construction context is suggested, and the concept of aspectual unit is introduced and it is shown how this concept can be used to integrate different aspect views in a conceptual schema.

TL;DR: In this paper, the authors propose a method for teaching digital design at a university level, where the digital tools, which facilitate the design process, are taught separately, so as not to dilute the design studios importance.

TL;DR: It is argued that embracing metaphors of play and games in the use of digital media in architectural education is an effective means of developing student confidence and abilities in spatial modelling, design composition, and form creation.

TL;DR: The goal is to establish a state-of-the-art common foundation that permits instructors, researchers and practitioners to refer to, utilize, test, criticize and develop.

TL;DR: A model for the application of imaging to the automation of infrastructure maintenance and results are presented for automated crack and joint sealing, focusing on the development and use of a line snapping machine vision algorithm.

TL;DR: The web site being developed by City University is known as the Virtual Building & Construction Environment and is designed specifically to support teaching/learning in building construction technology.

TL;DR: A detailed assessment of technical areas of concern to those attempting to execute capital projects with ERP systems is provided.

TL;DR: A research programme which addressed topics related to the conceptual design of robotic systems for construction, and developing overall design principles for top-down architect/designer applications was introduced.

TL;DR: The development of a floor-tiling robot with real-time quality assurance (QA) function, which means that all operations at a workstation — stabilizing and calibrating, loading tiles, etc.

TL;DR: The democratization of computer technologies is changing architectural visualization in two significant ways: that the availability of digital media promotes wider and intensive application of computer visualization and the extension of architectural design to visualization in information systems.

TL;DR: In this paper, an Intelligent Parametric Templates (IPT) for structural design within an Automated Building System (ABS) is presented, which demonstrates that comprehensive automation of general and detailed structural design is feasible for rectangular plan building types.
