A framework for research of IT application in Croatian construction companies

Abstract: Croatian construction companies are passing dramatically changes by privatisation and restructuring according to the market needs of today and especially during future huge reconstruction and development of Croatian (as well Bosnia and Herzegovina) economy. The market conditions in these Republics are for now: scarcity of financial means, scarcity of personal educated and trained in modern management methods, scarcity of some profiles of skilled people in construction, very strong competition of foreign companies, since Croatian (and B and H) market is now open for foreign companies. The specific after war conditions include also new legal and business structure (completely new legislative based on the practice of developed western democratic states) new financial structure and institutions (also based on the financial structure of the developed countries). In the chaining of the subsystems: [ ownership - undertaking - management - transformed ownership] , information technology is fundamental but not sufficient enabler for quality decision making and efficiently management of the construction processes. Based on the IT application, there are necessary educated and trained management people, adequate decisions, and realisation. By adequate IT application design and construction processes are probably rationalised and accelerated, by satisfaction of the high quality standards, so that construction companies could easier adapt to market needs. What are necessary prerequisites (organization, IT, personnel, other) for making and carrying out of the quality decisions? In which degree IT application (modern information technologies, expert systems, CAD/CAM, GIS, CASE) influence on decision quality? What are other factors are influencing (knowledge degree, psychological state, environment, market)? On such question have been proposed and accepted research program under the name "Development of IT application in Croatian construction companies" by Croatian Ministry for science and technology. The goals: * Continually research of development of IT application in companies that are active in design, construction and maintenance of construction objects. * Comparative overview of IT application state to different criteria * Proposition of strategy development of IT application in construction * Creation of IT data base for information and experience exchange between the foreign and domestic construction companies * Proposition of education programme of IT application in construction * The questionnaire is now in distribution, and research will be carried out in the next three years. * The paper will explain the research approach, and eventually the first results.

The validation of integrated CAD in building engineering design

Abstract: The need and the urgency to develop integrated CAD software for building design are well established in industry and academia alike. The means and the approach to achieve this objective are however not soclear and do not meet with general agreement. Even the final product itself - integrated CAD - has different meanings for different people.Like other research groups in building studies, we have developed a number of integrated building design systems in the last few years thateffectively combine different activities and types of expertise in a unified approach. For these successful research initiatives, the fundamental issue of validation remains a very difficult one to answer properly. On the one hand, reference cases do not exist to benchmark the operation of an integrated system, as in the case of experimental or empirical processes. On the other hand, no clear guidelines have emergedyet from commercial software developers in the construction industry that claim to have achieved 'integrated CAD' as soon as some form of file transfer exists between an application software and a CAD package.From the study of some integrated CAD systems for building design recently developed in industry and at the CBS, this paper will attempt tocircumscribe the main aspects of the validation issue, e.g. what are the characteristics of integrated CAD ? what kind of performance is expected from such systems ? are current systems delivering what building design practitioners need ?

4D CAD- an efficient tool to improve production method for integration of apartments in existing buildings

Abstract: This paper describes an ongoing research project on application of a 4D CAD tool for design and production planning of vertical extensions of existing buildings (over-roofing) in Stockholm city, for creation of a more densely populated city as the demand for apartments in the city centre increases. 4D CAD is a concept, which combines an object oriented 3D CAD model with time. 4D CAD is a kind of information visualisation that is easier to understand than traditional methods, such as 2D drawings and time schedules, which are used to manage construction projects. 4D CAD is a logical way of imaging a construction management tool. It is a tool that is conceptually much closer to an intuitive picture of a construction process than 2D drawings and time schedules. The 4D concept is developed at Stanford University and to support the concept researchers at Stanford have developed a prototype that is being used in some complex construction projects in California. The focus of the research project “Integration of apartments in existing buildings by use of Light Gauge Steel Framing”, which this paper is a part of it, is to improve production methods in order to reduce design, planning and construction time for conversions of, and extensions to existing buildings in the city centres. A way to improve the production methods is by utilising a 4D planning process in combination with industrialised production of building components. Extensions to existing buildings are due to the demand for new apartments in attractive locations in the city centres and shortage of land for housing in city centres. The Light Gauge Steel constructions have many benefits for conversions of, and extensions to existing buildings. According to research results the Light Gauge Steel Framing system is suitable for industrial production. This building system results in a very light weight building compared with traditional materials e.g. concrete which makes it suitable for over-roofing extensions. The materials used in the Light Gauge Steel Systems is thin steel members, plaster boards and mineral wool. Many of the problems, which occur during vertical extensions of existing buildings today, are solved when they are discovered, that is sometimes on the site. Some examples of these problems are poor compatibility between the existing building (structural components and material) and the Light Gauge Steel Framing, detail solutions of the building components, shafts and piping for ventilation, water, sewage and drainage etc. It is less expensive to discover and to correct errors at an early stage compared to solving them on the site. Further a lot of construction time will be saved, which will decrease the disturbance on existing surroundings. Several problems have to be considered in the planning process in order to minimise the disturbance on existing activities and surroundings. This could be done by the use of a 4D CAD planning tool. An over-roofing project located in the city means that the land to use during the production period is limited and expensive. Thereby is the logistic to and from the site more complicated. Consequently the site management and logistic of building components to the building site and their storage on the site is most important. In fact the 4D concept is an efficient planning tool to organise the logistic of the site during the planning phase instead of as today during the production. The site layout can be simulated and visualised with a 4D CAD tool for the actors in the project which in particular will help the site engineer to organise the activities, material flow and site logistic. The value of using the 4D CAD concept is studied by comparing the traditional planning process of a number of over-roofing projects in Sweden with the planning process of the 4D CAD concept. This paper discusses how a 4D CAD tool together with an industrialised production method can be used for improving the production process for an over-roofing project in order to reduce the construction time and with secured quality. The reader will understand and appreciate the added value in form of a more efficient way of managing construction projects.

Strategic Use of IT in Some European Construction Firms

Abstract: A study has been carried out in which a number of large construction firms in Europe have been investigated with regard to management thinking in the area of IT. There is a common understanding of the strategic importance of IT, but the means for using the technology strategically are not well developed. Some theoretical frameworks for analysing the firms studied have been developed based on earlier work done by management researchers. The project-oriented nature of construction may make it necessary to modify existing theories. It is believed that although these frameworks cannot be used directly in the strategy-writing process of a contractor, they can help create awareness and explain possible effects of various generic strategies. A number of problems arise in trying to compare strategies or investment patterns between different construction organizations. Some of these problems will be discussed together with some ways of coping with them. Some conclusions about similarities and differences in the management view of IT will be stated from an international perspective.

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.

Building and construction eXtensible mark-up language (bcXML)

Abstract: The EU IST-10303 eConstruct project aims to develop an XML Vocabulary for the Building and Construction industry. The vocabulary, called bcXML (from building and construction XML), supports eCommerce and eBusiness in BC, both nationally and over the borders of the different European member states. Especially the communication of meaning over the national borders is of crucial importance for the future usage of the Internet as a means to increase the industry’s competitiveness, its ability to co-operate, reduce cost of failure, and enforce the European market of BC products and services. This paper will present current ideas about bcXML; what it should look like and why. The model is written in UML (“Class Diagrams”). Basically the idea is to develop an XML Vocabulary that supports XML-based communication on a sliding scale of complexity. The end-users of bcXML will be provided with the simplest XML-based communication possible. Simple in the sense that notions like boiler, or roofTile have meaning, and simple in the sense that users can use their own language and dictionaries also for communication over the borders. Advanced users or software applications will be provided with more complex functionality. The model presented is meant as an explanation to the BC industry of what bcXML is about. As such it can be seen as the concept design. A more detailed UML model, the implementation design, focusing on implementation issues, is available separately. This UML model is in its turn is transformed into an “XML Schema” schema.

IT tools and support for improved briefing

Abstract: "The briefing stage is critical to the success of construction projects, however it is widely recognised that improvements are needed in this process in order to reduce the cost and optimise quality of buildings. Briefing involves understanding the client's needs and expressing them in a way that will ensure compatibility between the client's vision of the project and the resulting product. There are problems encountered in construction briefing which involve both clients and designers. There is little guidance and support for clients, whilst designers have difficulties both in capturing clients’ needs and conveying conceptual design options to them. There is a central difficulty, associated with language, communication and the exchange of information between clients and design teams, which is now gaining widespread acknowledgement. The CoBrITe (LINK/IDAC UK funded) project argues that the construction industry has yet to exploit the potential of IT systems to assist both parties during this critical phase. This is in contrast to later stages of design and construction where computer-based techniques and systems are commonplace. The overall aim of the CoBrITe project is to improve the briefing process through more efficient and effective use of existing and emerging information technologies that can support client and design teams. The project builds on the recent IDAC 88 project: Managing the Brief as a Process of Innovation, and its five key action areas for improvement: empowering the client, managing the project dynamics, appropriate team building, appropriate visualisation techniques, and appropriate user involvement. It is driven by the needs of solving challenges within the briefing and related design process, with IT a means to an end. The project brings together a group of companies from across the construction supply chain to work together towards the above aim. The methodology comprises: -An extensive literature review on construction briefing focusing on the process of briefing, human and cultural issues, and IT applications and their role within the process. ·The integration of the recent and current projects on briefing through interviews, establishing an electronic network and holding workshops. ·The formulation of a framework of enabling technologies and their potential role in facilitating the briefing process and overcoming human and organisational constraints. ·The development of a model which will facilitate the integration of activities and information sharing in the briefing process. The proposed paper will give a comprehensive overview of the CoBrITe project, including an analysis of the briefing practices and information requirement, an initial CoBrITe Briefing Process Model, the CoBrITe system architecture, and the description of the proposed framework that integrates a set of proprietary and commercial software applications aimed at supporting the briefing process."

The use of web-based tools to support a contractual claim in arbitration or litigation

Abstract: Most standard forms of building contracts provide for the use of arbitration as a means of dispute resolution, failing which, the parties have to settle their disputes in court. Each dispute is resolved by examining whether the party who makes a contractual claim is able to discharge his burden of proof in both the liability issue and the quantum issue. The scope of proof is usually prescribed by the building contract. Evidence of information, facts and opinions may be adduced in support of a claim. Most project information may be stored in a web-based information management system. In existence are also some IT applications which may assist in providing facts and opinions that may support a claim. 4D Modelling may be used to simulate critical paths for the evaluation of an extension of time claim. GPS may provide the tracking of the use of resources to help attribute the cost of their use to the basis of a claim. The latest technology of LADAR may assist by recording through time, the as-built status of the project at any one time thereby determining the real-time progress of work. The use of computer-generated evidence is provided for by legislation and case law. This paves the way to use web-based tools to support a contractual claim in arbitration or litigation by linking the whole system to a claims service that monitors the situations where a claim may be made and trigger off a warning so that the procedure of claim may be pursued by a party if he chooses to do so. The claims service should then extract the necessary data from the other services in the project web to build up a claim.

Case digitalo – a range of virtual and augmented reality solutions in construction application

Abstract: We describe a range of Virtual and Augmented Reality (VR/AR) solutions applied during the planning and construction of VTT’s new head offices, the Digitalo (“Digital House”) in Espoo, Finland. During the building phase as well as in later evaluations 2003-2006, the various approaches used for Digitalo’s visualisation included: radiosity rendering by still images; immersive virtual reality visualisation; mobile outdoors augmenting; augmented scale model; augmented web camera; 3D landscapes; and interior design by means of virtual and augmented reality. We employed various display devices ranging from HMD video glasses to CAVE screens, and from PDA’s to varying kinds of PC solutions. Some of our solutions, for example the augmented web camera and scale model systems, have not been previously presented and they appear here for the first time. Also, we describe the current status of the applied methods, as well as directions for future research. Altogether, we believe this case study to be among the most comprehensive ones in the world to include such a wide variety VR/AR techniques applied in a single building project.

The role of information management in the development of a strategic model of buildability

Abstract: The key to the successful irnpiernentation of buildability lies with the effective management of information through all stages of the project life cycle and across functional divisions. The majority of building design errors occur not because of the lack of information, but the lack of management of infortnation. Buildability requires information affecting the quality of project decision making tO be timely, relevant and effectively communicated to the decision makers.A strategic management model of buildability has been developed based on the working definition that buildability is "the extent to which decision made during the whole building procurement process, ultimately,facilitate the ease of construction and the quality of the completed project'! This strategic model is underpinned by the conviction that information technology offers the means to overcome the space and time communication problems which have beset previous attempts to introduce effective buildability programmes. The capacity to process and manage large quantities of data is seen as an essential attribute of buildability. The approach adopted is that of a holistic view of Factors which we likely to impact on not only the design and construction process, but of the total procurement process. This allows the boundaries of' the buildability management model to be adjusted to be appropriate to specific project coridirions. This paper will describe an information management framework which will support the implementation of the buildibility management model.
