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.

Numerical simulation of wind loads on high rise buildings

Abstract: Article presents a methodology of the numerical simulation of the wind on high-rise buildings, which was developed by the Department of Computer-aided design of structures of the Ural Federal University named after the first President of Russia B.N. Yeltsin. Paper includes the results of researches on development of a technique of determination of wind pressure upon high-rise buildings by means of numerical modeling in an ANSYS package. The investigation was carried out within the grant of the Russian Academy of Architecture and Building Sciences. The results are applied to calculation of wind pressure upon a number of high-rise buildings under construction in Yekaterinburg City (Russia). Simulation is performed in the program ANSYS. The simulated building is placed in a domain that is the numerical analogue of wind tunnel. Domain sizes are chosen in such a way that simulated buildings do not affect the flow of air on its boundaries. Shear stress transport (SST) turbulence model has been used. This model effectively combines the stability and accuracy to the standard k-? model in the areas, which are placed near the walls and the effectiveness of the k-e model at a distance from the walls with a smooth transition between them (input expansion functions). For the numerical solution of the governing equations the finite volume method was used (FVM). The scale of the turbulence is assumed to be 200-300m. Use of the developed technique is shown on the example of calculation of wind pressure and wind velocities in pedestrian area for high-rise building under construction in the City of Ekaterinburg.

The UK industry knowledge base feasibility study

Abstract: The UK Department of the Environment (DOE) has funded a feasibility study into the concept of an electronic knowledge base for the construction industry. It is envisaged that this knowledge base would provide a single point of entry for the UK, creating a gateway to all information of relevance to the A/E/C industry. A wide range of commercial, social and technical issues have been investigated in the study, which provides a recommendation of the best way forward together with a marketing strategy. The results of the feasibility study are summarised in this paper.

A synchronised process/IT model to support the co- maturation of processes and IT in the construction sector

Abstract: In recent years many efforts had taken place in order to develop process and IT maps within the construction sector. However, the subject of co-maturation between IT and the process has not been given enough attention. This has resulted in the development of impractical solutions because of an apparent lack of balance between the IT and process capabilities. For instance, some organisations in the construction sector have adopted the rapid prototyping concept which is widely used within the manufacturing sector without even investing in 3D modelling and VR technologies which are the most appropriate for this task. Paradoxically, some organisations have invested in these technologies, but rapid prototyping is non existent. This paper addresses the issue of co-maturation between the process and IT in order to establish a balanced profile. The work is based on the CMM (Capability Maturity Model) model which was developed by the Software Engineering Institute at Carnegie Mellon University in order to develop software for the US government, particularly to be used by the Department of Defence. The CMM is a five-level model which include ad-hoc, repeatable, defined, managed and optimised stages. The model is designed so that capabilities at lower stages provide progressively stronger foundations for higher stages, reducing the change management risks. Each development stage - or "maturity level" distinguishes an organisation’s process or IT capability. This paper builds on the work achieved within the generic design and construction process protocol (GDCPP) which is being undertaken at the university of Salford. The main contribution of this paper is a conceptual model of co-maturation between IT and process. A synchorised IT/process model will be presented and discussed. This model is being developed through knowledge obtained form the industrial collaborators of the GDCPP project.

Making Process Models Usable

Abstract: Process models have several fields of application. THe research community of construction IT has used process modelling methodologies for several years to analyse and share information. The construction industry has applied process modelling, among other things to better understand current business, to improve or innovate business and to create information systems that support business. Developing a business by using process models needs usable process models. This licentiate thesis describes how process mdels presented in a computer environment can be made usable to practitioners of the construction industry. A structure of concepts is developed that describes interactive environments for process models. The concepts are of two different types: objects and actions. Objects are components that carry the information, and they are not examined in this research. Twelve different actions are identified in the thesis: overview, zoom, filter, details-on-demand, decompose, relate, history, extract, browse, search, compare and find. Based on the concepts developed a prototype is developed. An authentic model built according to the IDEF0 process modelling method is displayed in the prototype. Finally, a usability study is performed to gain knowledge about the concepts and their implementation in the prototype.

The role of case studies in the uptake of innovation in construction

Abstract: The UK Department of the Environment, Transport and the Regions has initiated a Construction Best Practice programme. The primary objective is to improve management best practices. The technical performance of the industry also needs to be improved by identifying and promoting opportunities for industry to adopt new technical innovations and incorporate them into standard practices. Accordingly, a series of Technical Best Practice initiatives will be set up. One of these will cover Construction IT. It is expected that Case Study material will form an important element of the IT Best Practice programme. Concrete examples of use of technology in practice are likely to be more convincing than simple exhortations and theoretical reports. There are three major issues that need to be addressed. 1. A Case Study is, by its nature, very specific and it can be difficult for the reader to ascertain if there is sufficient commonality between the problem described and the situation that he/she faces in order to assess whether the solutions are applicable. 2. It is difficult to describe the problem and solutions in sufficient detail, yet in a way that encourages the material to be read, understood and used. Ideally a common format needs to be developed for describing the key facts. 3. A further aspect of importance is how to determine what applications are most in need of Case Studies. Limited resources are available and it is essential that these are targeted in such a way as to produce maximum returns for the industry as a whole. This paper describes a framework for addressing these three issues and will provide an update of the work of the UK Construction IT Technical Best Practice programme.

Management of dynamic projects within a virtual (paper-less) office

Abstract: This paper presents fresh directions currently being developed and implemented for project management of major works for the Highways Department of the Government of the Hong Kong Special Administrative Region (S.A.R). Techniques based on a new approach to computer-aided office practices and procedures, for office-based and on-site professionals and technicians. The intention is a replacement for previous technologies which are seen to be encumbered by outmoded traditional project information management processes. The Government of Hong Kong SAR gained considerable experience and immeasurable benefit from the use of IT, on what has been the world’ s largest infrastructure programme of the 1990’s, namely the new Chek Lap Kok international airport with accompanying arterial express routes. Through economic necessity, the Government plans to promote significantly more construction within the territory in the next two decades, with projects of comparable magnitude, commencing as the airport-core-programme reaches completion in 1998. What has emerged in the course of construction works since 1993, is a striking departure from traditional administration-centred-office-operations. It has become evident that project management processes must avoid being swamped by large volumes of project information and its dissemination. Disparate manual record keeping and paper document processing are a limitation and hindrance to collaborative tasking essential to any project. Computerised record keeping, status tracking and on-line project cost reporting are demanded as an essential panacea to these ailments. It is anticipated that full relief must be gained by implementing professional-centred-office, operations which provide full office automation: the creation of the ‘virtual’ project management organisation. The paper describes the practical research commissioned by the Highways Department to enable implementation of technologies for a practical information system to serve pragmatic people in the manner of a virtual project management organisation.

IBIS-calc a Dutch cost information system

Abstract: In the last few years a computerized cost-information system has been developed in the Dutch Department of Housing and Public Building, called Integrated Building Information System (IBIS-calc ). This system is based on a hierarchical information-model that answers the need for cost-information of those who are responsible for design, for costs and for project management. As this information-model (and a number of other aspects of the system) are generally applicable it may serve as an example, or prototype, for other information systems.

Computer software architecture to support automated building diagnostics

Abstract: Developed by Pacific Northwest National Laboratory's Building Sciences Group, Honeywell Technology Center, and the University of Colorado Joint Center for Energy Management with support from the U.S. Department of Energy, the Whole Building Diagnostician is a Windows-based application that provides building operators with easy access to system diagnostic information. The architecture of the software infrastructure presented provides essential data collection, validation, integration, analysis, and management functions for the large sets of discontinuous asynchronous time-series data used by all the modules in the application. The proposed architecture uses a central database to store both the data and the diagnostic results from the various modules. Although the use of a centralized database has many advantages, it has several shortcomings. This paper will discuss the advantages and shortcomings of such an approach when deployed on a large scale.

Conceptual models for communicating knowledge in the building industry - implementation of the cube system

Abstract: This paper presents the conceptual models that emerged during the development of the Cube demonstrator in the Cube project at Lund University in Sweden. The Cube project was led by the Department of Construction Management with the systems development being done by the authors, at the KBS-Media Lab of the Department of Structural Engineering. The paper presents the underlying conceptual models for knowledge transfer used in the Cube system. In the Cube system the formalized rules do not apply to the knowledge itself but rather to the way it is conveyed. The goal for these models is to assist a growth of building knowledge that is driven from the building site and the daily situations there. It is showed how knowledge chunks are labeled and stored in answer boxes specific for each project or building site. Existing classification systems, BSAB, are implemented together with a dynamic limited vocabulary and task-oriented headings to form an efficient knowledge communication and retrieval system.
