Development of a BIM and Barcode based Material Management System for Curtain Wall Industry

The construction industry is slower to adopt new technologies than other industries. Traditional construction industry material management system involves tedious paperwork, frequent phone calls and challenging coordination, posing many difficulties for the project management. Recent development in the use of information and communication technologies in the Architecture, Engineering and Construction (AEC), namely the building information modeling (BIM), promises to introduce major changes in visualization, coordination and planning processes of the engineering projects. The impact of the building’s curtain wall has become increasingly more important when determining the operational and economic performance of construction projects. And as a recognized discipline of the construction industry, curtain wall design, and fabrication and installation process involves numerous stakeholders including designers, contractors, purchasing staff, suppliers, distributors, and on-site installers. It is believed that the material tracking system, when integrated with BIM, can successfully address the major problems of the curtain wall industry. In this paper, the authors analyzed the current practice of material management in the curtain wall industry and proposed a BIM and barcode integrated material management system, which aims to provide a BIM based material management framework from the design phase to the construction phase, streamlining material management process and promoting collaborative working processes in the curtain wall industry

Suitability of BIM for enhancing value on PPP projects for the benefit of the public sector

Collaborative integrated working and stakeholder’s interest have been among key drivers that underpin and encourage the use of Building Information Modelling (BIM) within the AEC industry. BIM is becoming a major means to deliver projects with better improved product, and reduced risk within the construction industry. Furthermore, using BIM in areas like buildability, quality assurance, cost and scheduling can be justified through BIM-nD modelling application. What is not so obvious is how the utilisation of BIM visualisation and knowledge embedment will enhance these areas to refine and achieve better value for PPP procurement projects for the long term benefit especially during post-construction phase for the public sector. As of now there is no well-defined guidance with respect to BIM usage incorporating all of the above. Do we really need to revisit the way we specify projects within the contractual framework under PPP? This paper examines the possibility of how BIM can be utilised in the realisation of augmented formal database information management system under the PPP procurement routes with respect to operation and maintenance support. The paper concludes with additional measures that BIM can offer at the post-construction phase for the public sector at learning organisations

Improving knowledge management in construction industry by combining ontology with collaborative technologies

University of Technology, Sydney. Faculty of Design, Architecture and Building.The concept of knowledge management has been introduced to the construction industry for many years. Recently, its importance is more recognized as modern construction projects are more complex and globalized. Managing knowledge assets is a challenge, especially in the construction industry, as it is characterized as a project-based business which delivers one-of-a-kind product, and it has a highly fragmented working environment. While explicit knowledge has been handled by many existing commercial project information management systems, tacit knowledge is more difficult to handle because of its intangible nature, and so far very few computer systems have attempted to handle tacit knowledge. Tacit knowledge is usually created and transferred in a social environment, and maintained mainly in human's head. Therefore a combination of a group of advanced IT technologies should be adopted for efficient knowledge manipulating. In this research, web-based collaborative system, blogging technology, domain ontology and semantic web environment are used together to provide technology support for knowledge management. The original contribution of this research is that it demonstrates the effectiveness of using construction domain ontology in semantic blogging to promote knowledge sharing. While focusing on technology support, this research also investigates appropriate KM framework and system architecture for small and medium sized construction organizations. A prototype knowledge management system is proposed and implemented; some knowledge management cases are presented to demonstrate how the proposed KM framework and advanced IT tools could help the KM process in the construction industry

Planning and implementation of effective collaboration in construction projects

The 21st century is now seen as the time for the construction industry to embrace new ways of working if it is to continue to be competitive and meet the needs of its ever demanding clients. Collaborative working is considered by many to be essential if design and construction teams are to consider the whole lifecycle of the construction product. Much of the recent work on collaborative working has focused on the delivery of technological solutions with a focus on web (extranets), CAD (visualisation), and knowledge management technologies. However, it is now recognised that good collaboration does not result from the implementation of information technology solutions alone. The organisational and people issues, which are not readily solved by pure technical systems, need to be resolved. However, approaches that exclusively focus on organisational and people issues will not reap the benefits derived from the use of technology, especially in the context of distributed teams which are the norm in construction. Work currently being undertaken at Loughborough University aims to bring together the benefits enabled by the technology, with the organisational, and its people issues to provide a framework enabling high level strategic decisions to be made to implement effective collaboration. This paper reports on the initial stages of the project: the background to the project, the methodology used, and findings from the literature survey and the requirements capture survey conducted as part of the project

Integral value engineering in design

Construction industry clients demand certainty in project cost, quality and time. The inability of traditionally composed design teams to consistently deliver this suggests that their expertise is sometimes inadequate. As clients become more dynamic in the next millennium, they are likely to demand greater certainty when construction projects are implemented to support frequent revisions in their short term function. By establishing a collaborative working framework it is proposed that supply chains can be better managed to identify and design out potential problems using integrated, collaborative design processes. This proposal is being investigated by the Integrated Collaborative Design (ICD) research project, a collaboration of AMEC Construction, Loughborough University and eleven supply organisations, supported by the EPSRC and DETR through the IDAC Link programme. Focusing on one component of the ICD project, this paper reviews existing, reactive, value engineering methods and by identifying their inadequacies establishes the need for an integrated approach. A value management context is described which integrates value engineering into continuous design processes. The paper discusses the opportunities for utilising supplier design expertise by modelling design process information flows. It also identifies potential cultural barriers to the use of design processes incorporating integral value engineering techniques and describes the linkage to other ICD components that are addressing these issues

Towards Assembly Information Modeling (AIM)

Nowadays digital tools support architects, engineers and constructors in many specific tasks in the construction industry. While these tools are covering almost all aspects of design and manufacturing, the planning and design for the assembly of buildings remain an unexplored area. This research aims to lay the foundations of a new framework for the design for assembly in architectural applications entitled Assembly Information Modeling. In practice, it is a central digital model containing the structure architectural design, construction details, three dimensional representations, assembly sequences, issue management and others. This framework forms the base for a multitude of novel applications for assembly design, planning and execution, such as assembly simulation and strategies communication, problem detections in the early design phases and interdisciplinary coordination. This paper describes the specifications of the digital assembly model and illustrate two use cases: collaborative assembly design using AEC cloud-based platforms and Augmented Assembly using Augmented reality devices

MANAGING KNOWLEDGE WITHIN THE LEADING IRISH CONSTRUCTION ORGANISATIONS: CURRENT PRACTICES AND FUTURE DIRECTIONS

Despite the benefits which knowledge management (KM) can bring to construction organisations there appears to be a lack of understanding in relation to both knowledge and its management in practice. In the context of Irish construction, both Engineers Ireland (EI), and the Construction Information Technology Alliance (CITA) have identified KM as important to the future competitiveness of the industry. The findings of interviews with senior management from ten of the leading Irish construction organisations are presented, having been selected as they are perceived to possess the most advanced organisational processes. Three ontological dimensions were explored; individual, project and organisational, with a view to identifying current approaches to managing knowledge. The findings confirm that these organisations lack a proper understanding of KM, yet recognise the need for a more structured, coherent approach. The paper proposes the establishment of a strategic framework to improve the understanding of KM within the leading organisations, through a collaborative approach between academia, industry, EI and CITA. A central feature of this framework will be the development of a KM model which will be evaluated by participating organisations for its practicality

Framework for effective collaborative working in construction

The potential benefits of collaborative working in construction projects have yet to be fully realised in the sector. This is in part due to the misunderstanding of the use of the information and communication technologies (ICT) and tools associated with working collaboratively. There are, however, isolated pockets of experts that have realised that in order to fully embrace the potential of collaborative working in their businesses, the role of ICT has to be closely aligned with the people that use it, and should relate to the overall goals of the business. The aim of the Planning and Implementation of Effective Collaboration in Construction (PIECC) project is to develop a decision-making framework that enables organisations to fully integrate ICT and its associated people and business issues into their projects and individual businesses. This paper reports on the development processes used to develop the framework, and its evaluation and testing within the UK construction sector. The paper presents the different processes that should be followed to develop a joint collaboration strategy, and the results and implications of using the PIECC framework to manage collaborative working

Designing a novel virtual collaborative environment to support collaboration in design review meetings

Project review meetings are part of the project management process and are organised to assess progress and resolve any design conflicts to avoid delays in construction. One of the key challenges during a project review meeting is to bring the stakeholders together and use this time effectively to address design issues as quickly as possible. At present, current technology solutions based on BIM or CAD are information-centric and do not allow project teams to collectively explore the design from a range of perspectives and brainstorm ideas when design conflicts are encountered. This paper presents a system architecture that can be used to support multi-functional team collaboration more effectively during such design review meetings. The proposed architecture illustrates how information-centric BIM or CAD systems can be made human- and team-centric to enhance team communication and problem solving. An implementation of the proposed system architecture has been tested for its utility, likability and usefulness during design review meetings. The evaluation results suggest that the collaboration platform has the potential to enhance collaboration among multi-functional teams
