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.

Construction Delay and Disruption Claims Assisted Through BIM Technology

Abstract: Construction projects are frequently subjected to delay and disruption leading to dispute between project participants regarding the entitlement to compensation. Challenges associated with the analysis of delay and disruption and the subsequent preparation of the claim conducted by a forensic analysis expert include the difficult retrieval of scattered, unstructured information and lack of adequate documentation, leading to weak analysis and therefore insufficient proof of causation and entitlement.This paper illustrates the chronological information generation regarding delay and disruption in the construction phase proposing a framework based on Building Information Modelling and structured information integration, to facilitate easy filing and retrieval of relevant documentation for claim preparation.

Information and Communication Technology for Intelligent and Integrated Controls in Buildings: Current Developments and Future Research

Abstract: A common and acknowledged vision today is the one that, in the future, buildings, along with their components, equipments, and their environment will communicate and be able to provide information on their status ubiquitously. This real-time available information will be interoperable via common protocols for holistic automation & control. The whole building will be supervised by intelligent systems, able to combine information from all connected devices, from the Internet or from energy service providers in order to efficiently control HVAC (heating & cooling), lighting, and hot water systems along with energy production, storage and consumption devices inside the building, taking into account the users' needs and wishes. In such a context, ICT is recognised as key for empowering people in the (built) universe in which they live, with smart e-metering and new smart e-devices – as well as becoming fully pervasive in the future optimization of energy in the built environment - where “Energy-efficient smart buildings” are to be buildings which contain systems that manage information for an optimal operation of building energy flows over the whole building lifecycle.In such a context, CSTB has developed an open framework for data collection and processing, to be installed in any built environment. It supports networked heterogeneous sensors and actuators (with appropriate communication protocols technology), allows assembling various “business” functions (with easy evolution and extension capability thanks to a concept of service composition and event-driven management between modules), can accommodate any hardware platform constraint (memory, computing power), and can be executed in any environments supporting a Java SE implementation. The framework is itself based on an OSGi platform. The notion of “sensor” is to be considered in a comprehensive way: physical sensor (analogic or logic), complex sub-system or meta-sensor (e.g. Agilent data acquisition system or alike), or even external services (e.g. getting weather data via the Internet). Fields of applications are energy-efficiency in the built environment, but also Ambient-Assisted Living (AAL), internal air quality assessment, collection of data related to inhabitants behaviours, etc..The REEB coordination action (European strategic research roadmap to ICT enabled Energy-Efficiency in Buildings and construction), as a European R&D technology roadmap initiative (achieved in the context of an EC-funded Coordinated Action - http://www.ict-reeb.eu) has identified ICT contributions to the energy efficiency of buildings mainly via improvement (and corresponding RTD) in integrated design (and indeed ICT tools for Energy-Efficient design and production management), integrated and intelligent control, user awareness and decision support to various stakeholders throughout the whole life of buildings, energy management and trading, and integration technologies. As far as the integrated / intelligent control field is concerned, REEB has fundamentally identified the following areas for future investigation:• automation & control: system concepts, intelligent HVAC, smart lighting, ICT for micro-generation & storage systems, predictive control;• monitoring: instrumentation: smart metering;• quality of service: improved diagnostics, secure communications;• wireless sensor networks: hardware, operating systems, network design.The paper will first introduce to expectations, requirements and potential future scenarios for ICT to support integrated and optimised control in future so-called smart buildings. It will then introduce to the current trend of developments at CSTB in this area, and will present the CSTBox as a tool federating and/or complementing functions (potentially relying on already installed systems) in the built environment. After a short presentation of the REEB project, the paper will follow up with exhibiting the outcome of the REEB project in terms of roadmapping RTD activities in this technological field, also providing with a first insight of their potential impact in the future.Acknowledgement: the authors wish to thank the European Commission (DG INFSO) for its financial support to the REEB co-ordinated action. Moreover, the authors are also grateful to the REEB Consortium partners, namely ARUP, ACCIONA, CEA, LABEIN, TUD, UCC & VTT.

A BIM assisted rule based approach for checking of green building design

Abstract: Since the publication of green building standards from the last decade, the designer of green buildings have often encountered the challenges of limited time but considerable complexity in the process of evaluating their design according to the rules specified in the standards. Also, the design process is usually an iterative one, which includes rule-checking tasks that are tedious and repetitive. With the advancement of technologies in Building Information Modeling (BIM), artificial intelligence, and Virtual Reality (VR), this research investigates and develops a BIM-assisted Rule-based approach for automating checking of green building design. The developed approach utilizes as much information available in a buildings BIM model as possible to automate the design evaluation complied with green building standards. It also provides visual feedbacks through the BIM model to assist the designer in green building design. To evaluate and demonstrate this approach, an Application Programming Interface (API) tool has been developed in this research to extend the capability of BIM software for both automatic rule-checking of green building design and real-time visualization of feedbacks from the rule-checking. A rule base is used to manage the design rules specified in green building standards and facilitate the automation of rule checking. In addition, visualization of the rule-checking results (e.g. highlights of places in the design that do not satisfy the design requirements) is supported in a 3D VR environment of a buildings BIM model.

Integrating applications for the construction industry using a STEP-based integration platform (SIP)

Abstract: International construction industry has not still achieved a high degree of integration and automation in the past years. The European ESPRIT III project number 6660, RoadRobot (Operator Assisted Mobile Road Robot For Heavy Duty Civil Engineering Applications) intends to design and to implement an architecture to support the integration and automation tasks in that domain. To aid the implementation of the architecture, a STEP-based (ISO 10303) platform for integration of applications (SIP toolkit), was developed by UNINOVA. The general purpose of SIP is to assist the achievement of standardised Computer Integrated Manufacturing (CIM) environments, providing a set of development system tools. Last year, during CIB W78 and TG10 held at the University of Stanford - California (USA), SIP and the aim of the RoadRobot project were presented. During the CIB96, the RoadRobot architecture and its achieved results will be shown, as well as the improvements of SIP made in order to meet the project requirements. Special care will be taken concerning the problems found and the solutions adopted.

Planning UAV-Assisted Visual Inspections of Construction Sites

Abstract: Inspection flights on construction sites, carried out with Unmanned Aerial Systems (UASs), should be planned with safety as the primary priority. Although the generation of waypoints may be conducted in an automated fashion, with distance-to-object constraints implemented in the algorithm, the visual review of such flight paths by a human operator before take-off is crucial. Apart from safety concerns, finding the right camera orientation for taking photographs of specific details is a non-trivial task when the camera is mounted to an Unmanned Aerial Vehicle (UAV). The inspection planning application should interactively assist the operator with this task.We propose an interactive and simulation-based inspection flight planning concept. A realistic and detailed simulation allows a quick and intuitive insight about generated flight paths and possible shortcomings of such paths in terms of flight safety. Images, rendered from the virtual scene, with the flying cameras point of view enable the operator to assess the quality of the intended photographs before conducting the flight mission. These previews take into account the main parameters of the camera such as focal length and natural lighting. This minimises the need to readjust parameters or repeat inspection flights to get the right picture.

Integration of planning and control activities for building and construction: experiencing standards

Abstract: The effective exchange of information regarding the planning and control activities (schedules, resources, materials, cost, cash flow) between the different parties involved in building and construction projects is a critical success factor to avoid projects' time and costs overrun and to insure better quality. However, current applications and research and development efforts on electronic exchange of information are usually restricted to the exchange of technical design information, particularly CAD exchange amongst designers and between these and contractors; and of business data (purchase orders, invoices, remittance advice, etc.), between contractors and builders, merchants and suppliers. This paper will review current practitioners' approach to the exchange of planning and control information, and discuss the business need to the seamless flow of scheduling, resource, materials, and cost information between firms. Different technical solutions available to address the subject will be described. Through the description of the experience in this area of two European projects, RoadRobot and SUMMIT, the paper will also describe the state-of-the-art regarding the development of international standards for the exchange of planning and control information, particularly at the EDIFACT, STEP and IAI levels. RoadRobot - Operator Assisted Mobile Road Robot for Heavy Duty Civil Engineering Applications, was a project devoted to implement a general standard-based architecture to support the information management for road construction environments, covering from the road design to road construction, embracing the site, cell, machine and tool levels. SUMMIT - Supply Chain Management In Construction Industry, is an end-user driven project which envisages the creation, implementation, test and evaluation of an EDI, STEP and IAI/IFC based communication infrastructure on a specific project of building prefabricated houses, connecting project manager, contractor and suppliers. This paper shows that international standards for planning and control information in B and C are not yet enough developed and that further developments are required.

Product model: a basis for next generation CAAD

Abstract: Even at the very beginning of the use of computers in architecture there had already been the vision to use the new medium for more than just copying the draught man's way of work [l]. Thus, the search for such a computer assisted or even computer automated de- sign process, either for the more artistic or for the more constructive part of the architectural design process, has lasted as long as the history of CAD in architecture itself This search follows different concepts, which are, with more or less intenseness, AI approaches. The more artistic and creative aspects are to be solved by, e.g., Shape Grammar or Case Based Reasoning, the more constructive aspects by Expert Systems. These are approaches on a very high and demanding level. It is still not clear, how far the progress will lead to usability in practice. A more pragmatic but surely arduous approach is to built next generation CAAD system on the basis of a product model. The product model, however, will be a sound foundation for using case based or expert system approaches in a further step of the development. The Next CAAD project follows this approach. The model defines and describes the architectural design objects, their relations, dependencies and constraints. This will be done in a stepwise manner. A stepwise approach is also followed for the handling of dependencies and constraints. In a first phase the user will have to set the rules. In next phases small rule based modules will be taken over as far as they are proved useful.

The software design of a dynamic building model service

Abstract: We present the software architecture and a prototypical implementation of a dynamic building model service system. The primary purpose of this model service is to support (simulation-assisted) indoor-environmental control operations in buildings. However, as a comprehensive, structured, sensor-based, and self-updating information resource, the model can support other building tasks such as those concerned with building logistics and management. At the core of our model service design, an object tree continuously updated from sensor data reflects the current state of the building, concurrently accessible to multiple clients and backed by persistent storage. The service is embedded in a distributed infrastructure based on tuple spaces for transparent object-based communication between system components. The preliminary evaluation of the model service system suggests that the proposed design is feasible and appropriate for further testing in realistic (large-scale) settings.

DEVELOPMENT OF COMPUTER ASSISTED LEARNING TOOL FOR EARTHQUAKE ENGINEERING

Abstract: Today, we live in the world where the information and communication technologies are developing faster than ever before. We receive information and learn from a variety of sources. However, such learning is rarely related to the official programmes of higher education. Lecturers must compete with, for example, Discovery channel, games and/or other audio/video/internet media. That is why many students today have great expectations which even the well prepared and quality books cannot satisfy. Besides, it is difficult to attract their attention when the lessons are not dynamic and the lectured subject is not illustrated as it could be, considering all the technologies available. This paper describes a possible approach for teaching the basics of earthquake engineering through the use of animations (simulations) and active participation of the students. It could be a great addition to classical teaching methods in civil and earthquake engineering. Besides, the idea and the development of the prototype of the learning tool are described. That type of media gives the lecturer the opportunity to animate students, to give them the possibility to dig deeper into the discussed subject, and to learn through experimenting (playing) with carefully prepared examples.
