INVESTIGATING KNOWLEDGE MANAGEMENT IN PUBLIC BUILDING MAINTENANCE IN KUWAIT

Abstract: Public Building Maintenance (BM) departments in Kuwait have the duty of maintaining buildings that vary in shape, type, size, complexity and purpose. The services provided by the departments extend from minor repair works to bespoke renovation and reconstruction projects making the process of maintenance complex. Knowledge Management (KM) is being implemented by organisations to improve their business performance. This paper is based on a study that investigated the current state of KM in the public part of the BM sector. Interviews were conducted to identify BM process, current KM activities and tools, barriers to knowledge sharing and perception to KM implementation. Findings of the study have assisted in modifying a proposed BM process based on procedures followed by the majority of interviewed departments, where knowledge capturing, organising, and retrieval activities can then be embedded in the process. The study revealed that there is lack of formal knowledge management techniques carried out within departments. Furthermore, there is no established communication links between branches of the same department resulting in lack of experiences and knowledge exchange between colleagues. Cultural/ethnic differences, fear of losing job, not knowing how to share knowledge and lack of time were the main barriers to knowledge sharing. However, the participants showed a positive attitude toward the introduction of a KM system with added activities and roles in the BM process related to KM.

Human oriented mobile system for on-site problem solving

Abstract: Uncertainties and the dynamic nature of on-site activities require complex coordination of information, resources and tasks. Problems caused by unanticipated events must be solved concurrently and should avoid project delays and costs increasing. For effective solving of such problems, the immediate availability of information and a prompt response of project participants on various levels of project organization are crucial. A combination of both conditions facilitate the optimum decision-making in cases of unanticipated events. Based on experiences from a series of experimental projects called E-site, it is our strong belief that a large amount of potentials for on-site problem solving lies in the knowledge, experience and capability of the site staff themself. Therefore, there is also a need to effectively link together the rich knowledge and experience of site staff and include site staff into problem solving processes. This paper describes a human oriented on-site problem solving system supported with context-aware communication to help dealing with unanticipated events on construction sites.

Visualization of asphalt paving process during operations on site

Abstract: Presently important changes are occurring in the road construction industry, resulting in changing roles of road agencies and contractors. Additionally, a lot of new asphalt mixes with new properties are introduced, such as warm or even cold asphalt mixes, thin surfaces, etc. Despite these changes, the current asphalt paving process still heavily relies on the skills and experiences craftsmanship. Instruments to monitor key process parameters are seldom applicable. To overcome these limitations, real-time visualizations of key indicators such as asphalt temperature could provide decisive information to working teams oriented to adjust their operations on site. To move towards real-time decision making support, this paper introduces a workflow to deliver information in meaningful way by providing close to real-time and easily understandable visualizations of asphalt temperatures to roller operators. Using modern technologies like DGPS, temperature linescanner, and wireless connection on site it is possible to deliver visual information about asphalt temperature to support roller operators’ decision making regarding working paths. To implement user-oriented visualization we outlined an overall workflow including equipment selection, infrastructure organization, data processing and visualization phases. We validated the feasibility of workflow implementation through visualization of asphalt temperature on a real-world asphalt paving project.

Modeling the pragmatic solution

Abstract: An architectural project, designed with a modeling system was followed closely from sketching to detailed design, a report was made. Experiences on the use of a system with an architectural voca- bularium and architectural operations will be presented. The presentation will concentrate on how building modeling is facilitated by the system's understanding of building and buil- ding parts, and the way they are built together to form rooms, and on facilities to represent details without modeling in full detail as a short cut in modeling. The pragmatic solution to the problem of CAAD-systems with archi- tectural knowledge is discussed in terms of current limitations and further extensions.

Modeling a project scope using a case-based reasoning approach

Abstract: The availability of a good, complete scope definition in the early stages of a project is widely recognized by industry practitioners as a key factor for overall project success. This paper presents a Project Scope Modeling Methodology for computerized decision support during the definition of a new project scope. The methodology is based on the effective reutilization of historical project scope definitions through the application of Case Based Reasoning (CBR), an Artificial Intelligence approach. In CBR, the previous experiences are reused in solving new situations re-ducing the complexities of modeling reasoning processes. By using CBR, the scope modeling methodology helps to find and reuse the most relevant historical information, allowing to easily consult and combine information from multiple scope definitions in a computerized environment. The resulting scope definitions are ready to serve as input information for different planning purposes. The application for conceptual cost estimating is discussed.

Information technology teaching at the University: an experience at the Faculty of Architecture in Naples

Abstract: The experiences illustrated here refer to didactic activity carried out at the Faculty of Architecture of the University of Naples; in particular these concentrate on the technological aspects of the teaching of architecture. We can consider the evolution of the architect from individual operator to manager of the multi-disciplinary aspects of the building process (building process manager) as a reality in today's Italy. The Support Systems of Information Technology (ITSS), can be of great importance €or this professional figure, and for this reason it is important to include him/her in the teaching process. I personally have involved fourth and fifth year and last-year undergraduate students in the following subjects at the experimental stage: degradation diagnosis supported by m Expert System in courses of the Technology of Building Rehabilitation; co-ordinated System of tests in degradation of existing buildings; the use of three-dimensional programmes to survey and visualize rhe territory; rapid analysis of degradation in the maintenance of urban facades. * In these and other similar works I'TSS has played a significant part for a global synthesis in students' methodological approaches, being an inttoduc tion to new Information Technology potentialities.

Information Technology for Construction: Recent Work and Future Directions

Abstract: Advancing the application of information technology in construction is a major international research and innovation endeavour of concern to scientific establishments and industry. A significant focal point for this research, in terms of its dissemination and the derivation of a shared research agenda, has been the working commission concerned with IT for construction within the International Council for Innovation and Research in Construction (CIB). Working commission 78 of CIB has been active for about 20 years in holding annual meetings of leading scholars in the field. These annual meetings have allowed the principal research activities from around the world to be presented to expert fora and documented in a series of annual proceedings. More recently, some of the more complete research projects have been reported in an on-line electronic journal published in association with the working commission. The meetings have typically allowed debates and discussion to take place regarding the state of progress with key research themes, the emergence of new research themes, and a vision of construction activities in the future to which ongoing research could relate. This paper seeks to capture some of the overall experiences from the activities of this working commission by reviewing the key research issues that have been addressed in recently reported work and seeking to elicit a vision of future IT-enabled construction projects that might inform future research. It reports on an overview of the scope, current approaches and future research agenda that has arisen from consideration of the papers presented, and discussion that took place, at its most recent meetings in South Africa in 2001 and Denmark in 2002.

Keywords: Information Technology, Construction, Research Agenda, Vision.

Towards intelligent information system for public interurban road passenger transport management

Abstract: Public road transport forms a complex and dynamical domain that encompasses fields of traffic, business and politics. Management of the system poses a challenge for governmental entities which are responsible for coordi-nation, control and data gathering from private transport companies. A need for IT support is obvious. The paper systematically describes a distributed enterprise information system named AVRIS developed for the Direc-torate of the Republic of Slovenia for Roads. AVRIS adds new value to the management and coordination of the domain for public interurban bus transport. First a theoretical work flow model, consisting of processes, phases and states is defined. Built upon the model a multi-tiered IS architecture is developed which incorporates a number of advanced IT concepts, like application server, shared communication space, MVC, etc. The concepts are implemented using latest open source Java technologies. First real experiences with AVRIS are evaluated and presented in the paper.

What did you learn from practice today?

Abstract: The AEC-industry has been slow in turning the potential of ICT into increased efficiency and productivity. This is a phenomenon which can be observed in many countries, and in Denmark this issue has been recognized as a major problem for the further development of the AEC-industry. The public-private and nationally funded R&D pro-gram ‘Digital Construction’ was initiated in 2003 in order to establish a common platform for interchanging digital information and to stimulate digital integration in the Danish AEC-industry. This paper explores the relationship be-tween visions, strategies and tools formulated in the ‘Digital Construction’ program, and the first experiences of im-plementing the 3D work method part of this R&D program in an ongoing building project. The discussions in the paper are placed in the complex field between choosing strategies for integrating ICT on the national level, and the effects of these strategies on real life building projects. The knowledge gained from the experiences in Denmark could be a valu-able contribution to further discussions regarding strategies for integrating ICT in the architectural and engineering practice.

Building management simulation center

Abstract: Introduction to the BMSC In the Building Management Simulation Center new and experienced construction managers are trained. The center is unique because of the use of a virtual building site that can be inspected by the trainees. The actual status of the building and of the building materials and equipment on the building site is simulated by the system dependent on the trainee’s actions. The main part of the center is the simulation hall. Here, ten cabins are located with a view on a large parabolic projection screen. The trainee has to execute tasks in the cabin in an environment that is familiar to him/her. On the projection screen the building under construction can be viewed and it can be inspected by navigation through the full-scale model. Similar VR based training systems can be found in the aircraft industry, the automotive industry [http://www.ttsl.co.uk/home.htm] en de shipbuilding industry [http://thor.sv.vt.edu/crane/]. These examples inspired the initiators of the BMSC to investigate if the same methodology could be used in the building industry. Building site activity patterns Construction process simulation research has mainly been focused on the development of a construction planning analysis tool [e.g. V.R. Kamat, J.C. Martinez in proceedings of CIT2000]. In the BMSC though, interaction between the construction manager and the building on the building site will steer the construction process simulation. Investigations on the building site and discussions with experienced construction managers learned that they work in fixed patterns. A pattern consisting of a list of activities is called a transition type. These transition types describe all kinds of procedures that a construction manager performs to fulfill a specific tasks (e.g. ordering of new material). Transition types also take into account actions required to perform corrections beforehand or afterwards. For a specific case the transitions were entered into the system. The transitions were deduced from the construction managers that had worked on that building project when it was actually built. For the training purposes every possible situation the trainee can end up with has to be covered by the transitions. The interactive 3D training system The trainee’s actions are logged by a kind of Electronic Data Management System. All documents that are created during a training session are stored in the system. The system itself also contains project information that can be consulted. Finally the system offers an interface to communicate with the other participants in the project. After the training session that consists of the execution of a set of tasks, the system has stored all actions, their order and the produced documents. These data are compared with the predefined transitions for the case that was used. The document contents are compared with the predefined activity results. With this method it is easy to detect if the trainee missed certain activities in a transition and if the information is consistent. Finally, a visual feedback can be created be regeneration the 3D model in the VR environment in accordance with the trainee’s actions. The 3D model will show has far the building could have been built successfully. The learning effect After the training session the trainee will be confronted with the (possible) mismatch between has own actions and the preferred actions following from the predefined transitions. Evidently this is discussed during the evaluation after the training. Recognition of the right transition by the trainee to solve a specific task is considered one of the major learning effects of a BMSC training. Paper Outline In the paper the software architecture of the system will be explained. The activity patterns and the management of the system are discussed in more detail. A layout of the building where the BMSC is hosted is presented. Finally some examples of the training sessions will illustrate how the BMSC operates in practice and an overview will be presented of the first experiences.
