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.

CONNET: a gateway to Europe's construction information

Abstract: "The EC funded project CONNET (Construction Information Service Network, at http://www.connet.org/) has developed a set of Internet-based information services for Europe. These services are linked through a European gateway for the construction industry which provides a ""virtual technology park"", accessible to the whole industry regardless of national boundaries. The gateway provides mechanisms to link all information services for the construction industry, and to establish national gateways to services which can then inter-operate across Europe. The CONNET consortium is moving to establish the existing services in all European nations, and to encourage further existing or planned information services to be linked. A suite of five Internet based services has initially been developed, comprising: a technical information centre; a waste exchange centre; manufactured product services; a calculation and software centre; and an electronic news service as described below: 1. The Technical Information Centre provides a single point of entry to locate technical information from quality providers, initially in the UK. The centre draws upon information held by the major publishers in the UK, with over 200 identified to link into the service. Once a publication is identified a user is able to place an order to purchase, or browse, the item. An automated notification service for users, based on their areas of interest, is also available as part of this centre. 2. The Waste Exchange Centre extends the current UK based system to better enable the disposal and reuse of site waste across organisations Nationally and in Europe. Availability of, and requests for, waste materials are automatically matched in order to broker greater reuse of materials. 3. The Manufactured Product Service enables Finnish and export-market users to identify manufactured products which match their design specification by incorporating product attributes into the selection system. Users are able to identify certified products and drag-and-drop CAD information into their designs. 4. The Calculation and Software Centre provides the European entry point for information on all software products available for the civil engineering domain (over 3,900 collated to date). Online demonstrations, online purchase, and even pay-per-use software is available. 5. The Electronic News Service enables members of the construction industry to register an interest in specific topics and to be notified of any Internet published news that matches their interest. The news sources are drawn from the main information providers and professional institutes in the industry, both within the UK and Internationally. Currently over 14,300 Internet sites have been identified and indexed for this service. This paper describes the infrastructure which has been developed for the European gateway and the benefits it can offer to linked services within a single nation, or across Europe. The virtual technology park infrastructure developed in CONNET provides for user identification, centralised user profiling and profile management, automated and periodic user profile servicing, classification system management and mapping, discussion groups, secure communication and service validation, etc. The way in which these technology park services are able to be used and adapted in independent, but linked, national services is highlighted in the paper. The five individual services are also described briefly, highlighting the benefits they offer to the European construction industry and the possibilities they offer in terms of ensuring national services are inter-operable across all of Europe."

Re-engineering of the project planning processstrategic implementation of project management software

Abstract: This paper presents a model for re-engineering of the project planning process frombeing manually performed to be computer supported. The primary objective of thisstudy is to facilitate the implementation of project management software packages inorder to make use of the full potential of the software. Earlier studies show that thecurrent use of computer supported planning among project managers of buildingprojects is focused on print-out of schedules and the use of more advanced planningfunctions is limited. This study shows that only education and support is notsufficiently for project managers to adopt computer supported planning. Successfulimplementation of project management software also requires clear objectives of thecomputer supported planning and specified requirements and requisite level ofplanning details. This paper presents an approach on a strategic implementation ofcomputer supported project planning on basis of the surplus values related to the useof project management software. The results are based upon a case study at one ofSweden's largest construction companies.

Keywords: Computer support, project management, project managers, project planning,scheduling, software implementation, software support, surplus value.

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.

Enterprise integration of future building design systems

Abstract: The paper deals with the project and enterprise environment of integrated building design systems (IBDS), such as the one targeted in the European collaborative research project COMBINE. "he research has concentrated on the concept of a set of separate actors, grouped around a common data repository. Its deliverable consists of the first large-sized fully implemented conceptual building model. The actual data exchange is realized by STEP interfaces supported through a COMBINE interface kit. The resulting prototype was demonstrated in a workshop with design practitioners. The second phase of COMBINE has started recently and will build upon the above deliverables by combining them into an operational system, according to functional specifications derived with the help of practitioners in typical design office settings.

An information exchange measurement matrix for construction organisations

Abstract: The successful introduction of electronic information exchange within and betweenconstruction organisations is dependent upon organisations being receptive to newtechnology. This is a business not a technology issue and a full understanding oforganisational aspects is imperative if electronic information exchange technologies are tobe successfully introduced. Moreover, unless organisations are aware of the changesrequired and participate positively in the process of change then new systems will not realize their full potential.Following consultation with the IT management of leading construction contractors thecritical factors relating to the successful introduction of electronic information exchangewere identified. These were divided into two categories: those factors independent of theapplication function; and process related factors. These factors are reviewed and presentedin a matrix. This is the Information Exchange Measurement Matrix a tool for organisationsto determine their progress towards the successful adoption of electronic commerce. Thetool is independent of the type of information exchange technology that is to be adopted.Organisations may use the matrix to establish their readiness for the introduction of newtechnologies. Consideration of how to move from one element of the matrix to anothergenerates the critical factors necessary to effect such change.

I-SEEC: an internet gateway to european construction resources

Abstract: For the construction industries to move into the knowledge society and knowledge economy they need to be able to build upon their existing information base. This information base is unique within individual countries (though often with significant overlap between countries, for example, with Eurocodes utilised across Europe) and usually widely dispersed. Drawing together the information resources within nations, and then connecting them with each other to form trans-national resources enables a more effective, informed and intelligent industry. I-SEEC is a collaborative project funded by the European Union with the overall goal of creating an infrastructure to enable and link high quality commercial electronic information services throughout its member countries. This project started in March 2000 and finishes in April 2001. It builds upon a previous EU project - CONNET (CONstruction information service NETwork). This paper provides a description of the final state of the infrastructure, services and business models available through I-SEEC. The countries participating in I-SEEC are Finland, Iceland, Italy, the Netherlands, Slovenia, Spain and the United Kingdom. CONNET provides access to a range of high quality Internet-based services for the construction industry in Europe. It provides both a European entry point to identify resources and national entry points for localised service delivery. The European CONNET entry point provides a range of technology park services as well as industry-specific services. These services include: · Management of security services, including installation and monitoring of security systems · Help desk, providing a point of contact for potential service providers and for problem resolution · Information broker role, enabling transparent access to information in the CONNET services · Technology observatory service, including leading edge, current and best-practice technologies · Provision of user profiles, allowing personalised delivery of updates in areas of interest · Multi-classification support, permitting handling of national systems used across the EC. · Inter-service communication services, allowing all comparable services to be identified and a query to be passed from one service to another service to answer. · Multi-language support, enabling EC languages to be handled correctly and to provide basic translations between them. The services offered by I-SEEC include a Technical Information Centre, Waste Exchange Centre, Electronic News Service, Calculation and Software Centre, Who's Who in Construction, Specialist Equipment Directory and a Best Practice Information service. The CONNET infrastructure and the I-SEEC information services provide the means to promote effective use of information by construction industry professionals in an efficient and cost-effective way. The ability to pass queries from one high quality service to another in a different country is a substantial contribution to the CIB goal of providing information to achieve performance. This paper draws out lessons learned - both technological and practical - in the course of this multi-country initiative to develop a portal for the construction industry. It also invites participation in this open initiative and describes how existing and developing services across the world can be made interoperable within a CONNET (and any Internet portal) environment.

Interpesssnal communication of price-related information at the project inception stage: an interview survey

Abstract: The premise UPOn which this gaper is based is that, within the context of information transfer, there has been insufficient examination of the interpersonal communication function. This paper is concerned with the effectiveness of the interpersonal communication process associated with certain communication media utilised in the provision of price-related information at the inception stage of the building procurement process. More specifically, it deals with communication aspects of quantity surveyors’ engagement letters and documentation, clients’ briefs, and the language of building price forecasting. The paper documents the results of an interview survey concerning the opinions of clients, architects and quantity surveyors.

Knowledge management strategy for construction: key I.T. and contextual issues

Abstract: "Most business organisations often cite the staff as their greatest asset but have no appropriate mechanisms for managing the knowledge or intellectual capital that is embodied in these staff. The importance of Knowledge Management is now being realised and businesses are starting to formulate strategies and to invest in systems that will enable them to manage their corporate knowledge. This is a relatively new concept for construction organisations, which have a fundamental need to manage knowledge as they move from one project to another, working with different partners and supply chains. The aim of this paper is to explore the information technology (IT) and contextual issues involved in formulating an appropriate knowledge management strategy for construction organisations. It begins with basic definitions of knowledge and knowledge management, and then emphasises the importance of knowledge management in a construction setting. Drawing upon a number of research projects at Loughborough University, the paper discusses the contextual aspects of knowledge management. These include such issues as what types of knowledge should be managed, when and how; the business benefits that result from improving cross-project and inter-organisational knowledge management; the common groupings of knowledge classes, their appropriate transfer mechanisms and the implications for their management; the implications for an organisation’s policy, structure and working practices raised by managing knowledge across projects and enterprises; and how to develop an effective strategy for managing knowledge as an asset whilst enhancing the intellectual capital of an organisation within the constraints set by the business context for that organisation. Other issues relate to the relationship between knowledge management and improved business performance, and the cultural barriers to knowledge management. The paper also examines the role of information technology (IT) as an enabler for knowledge management, and reviews the some of the main IT systems that are being marketed as knowledge management tools. The concluding section of the paper formulates guidelines that will enable construction organisations to more appropriately develop IT and knowledge management strategies that will enable them to improve their business performance."
