User driven innovative building design

Abstract: During recent years there has been an ever-increasing focus on the possibilities to change the building process to raise quality on the final building products as well as on the activities of actors involved in the building process. One reason for this interest is the new opportunities evolving due to the broad introduction of advanced information and communication technology (ICT). VICMET is a general method for user involvement in every phase of the construction process and with a unique setup for each type of user. VICMET can use already created information in the building process and emphasis that the users are the key to next level of successful building projects. VICMET defines four spaces to support the activities in a innovative/creative design process; The Contextual Inquiry Space, the Conceptual Modeling and Game Space, the Functional Building Systems (FBS) Consolidation Space, and the Solution Space. In addition to these spaces there are supporting artifacts like Idea Bank and Good Story/Best Practice bank as well as Ontology containers and access to Communities of Practice and Interest. The project has so far validated the need for enhanced methods to involve end-users of buildings in a collaborative/participative creative and innovative building design process. The AEC professionals also appreciate development, enhancement and to some extent formalization of existing methods for user involvement in the building process.

ICT enhanced buildings potentials

Abstract: The paper describes and gives example on how Information and Communication, ICT, can and will en-hance and support the building functional systems defined from client and end-user needs and requirements. The build-ing systems may be derived from functional requirements on buildings such as usability and security on highest level with sub-systems definitions on lever levels. Building functional sub-systems may be defined for user comfort, indoor-climate, evacuation, space configuration, aesthetics, O&M etc. These building systems are supported by Information and Communication Technology, ICT, and building component systems that are accessed and integrated in the real world of building use in different contexts. The ICT systems may be physically or virtually embedded in the building. Already in 1982 AT&T established the 'intelligent buildings', IB, concept due to marketing reasons and the Informart building was established in Dallas as a showplace for IB installations. The interest in IB has fluctuated since then. There may be a fruitful interaction between user needs pull and ICT break-through push for creative and innovative development of ICT enhanced buildings. The paper explains the Intelligent Building concept with focus on virtual build-ing models support, new services and user environment definitions and development, virtual spaces and augmented reality, intelligent building components, application ontologies, and ICT systems integration to illustrate ICT enhanced buildings potentials and R&D needs.

IMPROVING COMMUNICATION OF SCHEDULING INFORMATION OF EARTHWORK CONSTRUCTION PROCESS USING 4D VISUALISATION MODEL IN ROAD PROJECTS

Abstract: Innovative visualization technology applied to construction simulation and optimization has the potential to improve communications and coordination amongst the project stakeholders. In this context and in the drive for innovation in construction management, this paper introduces a framework of a 4D prototype for the automatic generation of visual terrain surfaces during earthwork construction processes. The framework has been designed and developed by integrating road design data, quantities of cut and fill, productivity models, algorithms for modelling terrain profiles and a road profile visualiser. The paper details the prototype of 4D visualization model (4DVM) that has been designed and developed in this research using innovative methodology where 4D models of terrain surfaces are generated based on coordinate data and the productivity of earthwork. The model has been demonstrated with a case study that was used to validate the model. The 4DVM is intended to assist project planners/construction managers in logical decision making processes for construction scheduling and resource planning. It will also improve the communication gap amongst the construction team and consequently improve site coordination and operations.

Keywords: Earthwork operations, innovative methodology, road profile generation, schedule communication, 4D visualization model (4DVM)

An Innovative Approach for Generation of Virtual Construction Model and a Time Location Plan for Road Construction Projects

Abstract: Construction managers require innovative techniques to assist them in producing accurate planning tasks such as resource allocation and costing of activities, because of unique characteristics of the road construction industries. The research study introduced a framework for Virtual Construction Model (VCM) that includes 4D modeling and automatic generated time location plan for earthwork activities in a road project. The framework is designed by integrating road design data, quantities of cutting and filling sections, variable productivity data, algorithms for 4D terrain modelling, and a progress profiles visualiser. The model is validated with a real life case study of a road project and it was found to be beneficial in gene-rating the 4D terrain surfaces of progress, cost histogram and a time location plan with more accurate infor-mation of location and time in the earthwork operations. The VCM has potential to assist project planners and construction managers in producing efficient construction scheduling and resource planning.

Development of innovative visualisation model in road construction

Abstract: Visualisation models have the potential to improve the management process of construction operations through a better understanding of what is needed to be built and when. In that context and in the drive for innovation in construction management, a framework aimed at the development of visualisation models of ground profiles for con-struction process has been conceived, designed and developed using road design data, construction site information and a RoadSim simulator. The sectional quantity of earthwork activity, which is generated by road design data, is the key input to the framework. The RoadSim simulator has been integrated with the framework to determine productivity and required equipment of a road activity where as the construction site information has been integrated to establish precedence relationships of tasks in order to develop a detailed schedule and visualisation models. In this paper, an innovative methodology is presented based on the derivation of a mathematical model for the automatic generation of ground profiles throughout the construction process. The developed models that is defined as Innovative Visualisation Models (IVM) will assist in communicating the construction scheduling information to project managers/planners through visual evaluation of road construction process in order to facilitate a logical schedule development and effi-cient decision-making process. The paper outlines and discusses the framework and demonstrates a small case study in a road construction project.

A scalable working model for cross-disciplinary global teamwork education

Abstract: Our mission is to prepare the next generation of architecture, engineering, construction (AEC) profes-sionals who know how to team up with professionals from other disciplines and leverage the advantages of innovative collaboration technologies (ICT) to produce higher quality products, faster, more economical, and environmentally friendly. To achieve this mission we have been offering the AEC Global Teamwork course established at Stanford in 1993 in collaboration with universities worldwide. The AEC Global Teamwork course was described in many previous papers. This paper examines this course as a scalable working model for cross-disciplinary global teamwork education. More specifically we discuss the following dimensions: (1) a growing global learning network, (2) expanding the cross-disciplinary engagement, (3) evolving ICT EcoSystem, and (4) increasing number of social worlds students distribute their attention.

A2D2A2D… Seamless transformations from analog to digital worlds in support of global teamwork

Abstract: In today’s communication intensive environment the rapidly changing nature of work, learning, and play is driven by more and more collaboration, globalization, digital media, interactive devices and spaces, mobility, and convergence of virtual and physical spaces and places. The people and their knowledge are the key corporate asset. Managing, transferring, and reusing knowledge can lead to greater competitive advantage, improved products, and more effective teamwork. The most effective means of knowledge creation and transfer from experts to novices in both education and industry settings is through stories and dialogue using analog channel such as verbal discourse, ges-tures, annotations, and sketching. Current knowledge capture and reuse solutions do not afford to capture and utilize the relevance embedded in these multimodal streams of communication. This paper explores innovative approaches to support (1) seamless transformations from analog and digital worlds, and (2) cross-media retrieval and interactive re-play of multimedia content in support of global teamwork.

Keywords: Analog, digital, knowledge management, dialogue, gesture, sketch, data mining, cross-media capture re-trieval and replay

An innovative infrastructure for inter-working between dissimilar edm solutions

Abstract: The paper gives an overview of the European Esprit Condor project (ESPRIT 23105). The project aims at providing a large range of industrial areas, including the Construction industry, with an innovative infrastructure for distributing information and achieving co-operative work between heterogeneous Electronic Document Management (EDM) legacy systems, while ensuring document consistency throughout ongoing projects. The paper, first, presents the proposed technical solution, and gives a comprehensive description of the Application Programming Interface supporting the proposed inter-working and semantic linking services. The paper also includes a brief description of the modelling infrastructure supporting the proposed Condor system. Finally, a demonstrator involving the AutoCAD application, along with the Electronic Document Management systems used within the project, is presented. The latter demonstrates the Condor semantic-linking services. The project is ongoing and supported by a user interest group, which involves representatives from a variety of non-construction industry companies all over Europe.

Analogy based estimation in building services

Abstract: The introduction of Private Finance Initiative in the United Kingdom has prompted the need for quality whole life cost information. This in turn has led to a search for new innovative methods for producing whole life cost information. The research reported in this paper is a part of an overall approach being developed for whole life costing of building services. A particular problem identified in producing initial estimates of the whole life cost of building services is that the information on the building services design is limited. Analogy Based Estimation (ABE) was investigated as a potential approach to generate more information for estimation purposes and to estimate the capital cost of building services. The performance of ABE was investigated in three test settings. The estimation performance of ABE was compared with the estimation performance of linear regression (LR). ABE outperformed LR on two test settings. However, the estimation performance of ABE was found not to be sufficient for the approach to be applied in industry prior to further investigation. The tests were hindered by lack of data and inconsistencies in the data obtained. Therefore, no conclusions can be made on the applicability of ABE in this particular problem domain and ABE remains a potential approach. The research described in this paper will stand as a starting point for further testing and development of ABE in the estimation of building services.

INFORMATION MODELING AND SIMULATION TO SUPPORT SUSTAINABLE CONSTRUCTION

Abstract: The transformation process towards sustainable construction will be greatly improved by the adoption of Information Modelling combined with simulation capabilities. Indeed, the impacts of the built environment upon global climate change as well as associated economic and political issues represent complex and multidisciplinary challenges to which the construction industry must respond through the implementation of innovative business processes as well as systems integration both facilitated by information technologies.In particular, the coupling of BIM (Building Information Model) with information about environmental dimensions of building materials and components (e.g. carbon footprint, energy performance …) allows simulation packages to predict the effects of using different materials / components in various conditions. This will produce significant advantages to the designer by allowing to take into account the environmental impact of the building over its lifecycle. Many factors can then be considered such as the use of potentially lower carbon footprint materials and their energy performances along with trade off’s associated with the cost implication and the use of renewable energies.In that context, the paper will address R&D conducted by CSTB and aiming to develop a BIM based prescription tool coupled with environmental assessment functionalities. This tool allows to import a BIM / IFC coming from the architect and then, depending on the performances to achieve (e.g. the annual energy consumption), will search the industrial catalogues and then propose to the user relevant systems adapted to his project and the performances he wants to achieve. The quantity take off for materials and building products used for the construction are then automatically calculated and used to evaluate the environmental impacts of the building using Elodie, the building LCA tool developed by CSTB.
