A decision support system for building refurbishment design

Abstract: "Refurbishment work in the EC currently accounts for more than one-third of the total construction output. This market is expected to grow stronger with the progressive ageing of buildings and the environment impetus to retain buildings. A further dimension is the need to adapt buildings for a greying population. There are important differences between refurbishment and new construction works. The existing building constraints the design solutions, construction technologies and work methods. Mechanisation, planning, and efficient organisation of refurbishment work is difficult, due to the small, labour intensive, and ad hoc, dynamic nature of the work. Also due to the relatively small scale of refurbishment projects, there have been no opportunities for standardisation and the applications of prefabrication and industrialisation are limited. Today, larger sized contractors are rapidly moving into the refurbishment market, in response to the shrinking new-build market and the higher technological demands of large scale refurbishment projects. The EC funded Brite Euram project 4670 is titled ‘Decision Support Systems for Building Refurbishment.’ This project has started in August 1998 and will finish in July 2001. Its objective is to develop a socio-technological-commercial framework and corresponding Decision Support Systems (DSSs) for housing refurbishment, to achieve: ? refurbishments which are more focused on user requirements; ? refurbishment designs which take into account the constraints of the existing building structure; ? increased incorporation of industrialised systems and components; ? organisational procedures and production technologies that recognise the unique nature of refurbishment work. The project is divided into three tasks. Task one aims at developing a DSS for the determination of the refurbishment demand and ballpark costs. Task two involves the development of a DSS for refurbishment design. Task three will result in a DSS for refurbishment process planning and control. This paper describes the approach followed for the ongoing development in task two, the DSS for refurbishment design. The main objectives of this task are to provide decision support at the project level. It will develop a database of layouts of representative existing housing estates and a database of preferred refurbishment layouts for these representative existing housing estates. Another database will be developed containing information on building systems and components that are relevant for the refurbishment process. Task two will establish a protocol for refurbishment design support. This protocol, which is implemented in a decision support information system, involves a number of steps that aid the user in selecting an appropriate housing layout and building systems and components that meet the user’s requirements. These steps involve the evaluation of a the user’s refurbishment demands and selection of a matching representative existing housing layout. Based on further dialog with the system, a preferred refurbishment layout is selected, which in turn is used as the basis for the selection of building systems and components that meet the performance requirements as stated by the user. The paper describes the methodology that is implemented in the system for retrieving performance requirements from the user, and the approaches for matching these to the stock of existing and preferred housing layouts available in the system’s database. The system is characterised by a flexible architecture of both the databases and the user interface, which results in a scalable system that allows the expansion of the databases with new graphical layouts and building systems and components, as well as the addition of new kinds of performance requirements. The system is implemented as an Internet application, which allows the database to be maintained centrally and facilitates world wide access to the system. The system’s implementation involves the combination of graphical and non-graphical data that can be queried and matched with only typical Internet browsing software installed at the client-side."

Towards Semantic Interoperability in Virtual Organisations

Abstract: Virtual organisations (VOs) are amongst the most advanced forms of doing business to date. Their emergence and growing capacities are closely related to the networking and collaboration capabilities provided by a supporting ICT infrastructure. However, whilst considerable progress in the development of such infrastructures has been achieved over the years, interoperability still remains a major challenge. In this paper we analyse the nature of the semantic interoperability problem, review the state of the art, and derive a set of requirements. On that basis, we propose a novel semantic interoperability framework for VOs, utilising current semantic Web technologies, and suggest possible design and implementation methods for its achievement. Reported is in-house work of the authors as well as on-going research in the frames of the EU project InteliGrid (IST-2004-004664).

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.

The Future Scenario of Creating a Digital SME Community in the Irish Construction Industry

Abstract: The problems associated with the Construction Industry not being able to manage and communicate electronically product and project data between collaborating firms and within individual companies is compounded by the large number of small companies that have not adopted advanced Information Communication Technology (ICT). The typical nature of the service provided in construction, being an on-site and often highly customised service are generally identified as the reason for the low ICT uptake. The majority of Irish companies in the construction sector are Small to Medium sized Enterprises (SMEs). As eBusiness opens up the Irish economy to international competition Irish SMEs should use ICT as a generator of competitive advantage to become more effective and efficient with eBusiness technologies. The Construction IT Alliance in Ireland has identified a programme that can create a digital SME community that will promote ICT services in the Irish Construction Industry in order to compete in the global economy.

CITAX: A COLLABORATIVE ICT STANDARDS MODEL FOR THE IRISH CONSTRUCTION INDUSTRY

Abstract: The Irish construction industry is facing a series of fundamental challenges that is affecting every player in the AEC lifecycle, from architects to engineers to quantity surveyors to owners to tenants. Despite technological advances in recent years, the Irish construction industry lags behind other industries in respect to ICT investments. Although there is a pressing need for innovation, existing procurement and tendering procedures in Ireland largely discourage new ideas and put further pressure on thin margins that characterise the competitiveness of the construction sector. The low level of inter-company ICT connectivity reflects the general fragmented and adversarial nature of the Irish construction industry, where the absence of dominant players has precluded the imposition of de facto inter-company ICT standards, as has been the case in the retail supermarket sector. This paper will present the results of a two-year research project which sought to demonstrate that, by the adoption of readily available ICT tools, particular business processes in construction could be dramatically improved. The paper goes on to describe the opportunities and challenges that have arisen as the project draws to a close. It will, in particular, focus on the introduction of ICT standards within the Irish construction industry. The ultimate goal is not only to have ICT standards in place, but also to provide the impetus to ensure that as many stakeholders as possible use them. How this might be achieved is also part of the project and its success will be judged by the extent of the adoption of the standard by the industry.

A tool for developing knowledge management strategies

Abstract: While organisations recognise that Knowledge Management (KM) is essential for improving performance, many have difficulties in developing strategies for implementation. The nature of knowledge is of particular complexity in organisations such as those within the construction industry characterised by temporary 'virtual' organisations formed for the completion of projects. A significant proportion of construction organisations realise the benefits of KM but most remain at the infancy stages of developing and implementing KM strategies. This paper identifies the need for a methodology to help organisations establishing these strategies. It then describes a framework developed within the CLEVER (Cross-sectoral Learning in the Virtual Enterprise) project at Loughborough University. The framework introduces a methodology that supports KM at both the tactical and strategic levels in order to aid organisations, especially in the construction and manufacturing industries, in developing KM strategies. The methodology was encapsulated into a prototype software system to achieve a simpler format and is easier to use. Industrial collaborators evaluated both the paper format and the prototype software and it is evident that the developed methodology has the potential to provide a very useful way for developing KM strategies and that very little exists elsewhere to assist companies in developing KM strategies in this way. The software prototype was seen as an important enhancement to the paper version. The inviting format, simplified guidance, reduced input duplication, and automated report generation were found the most significant enhancements. The focus of this paper is on the development and operation of the prototype. Its key benefits and lessons learned in implementing it are highlighted in the paper.

Keywords: Construction organisations, knowledge management, KM strategies, software prototype.

Information and communication in construction : closing the loop

Abstract: Both nationally and internationally, the architecture, engineering and construction (AEC) sector is highly fragmented : it is dominated by small and medium-sized enterprises (SMEs), the nature of information and knowledge can be dispersed among firms and organisations, and consortia are frequently formed from geographically dispersed firms. In recognition of the potential improvements to be gained through an integrated approach to project information used throughout the design, documentation, construction and operation processes, substantial research is underway in Australia to "close the loop" of information flows between designers and constructors. The paper will explore and discuss both the technology platform in terms of information and communications technology (mobile, high-speed and wide area networking linking the design and engineering offices with the construction site) and the information platform in terms of the content of communications between project stakeholders and the requisite information (traditional spatial as well as non-spatial data) of key concern to the stakeholders at various stages of the project lifecycle. The paradigm shift that has occurred over recent years from stand-alone personal computing (which reinforced fragmentation) to mobile and Wide Area networked computing now provides a platform capable of promoting integration, accessibility and co-operation within the sector with attendant gains in efficiency. A minimum requirement to achieve these gains is access to the right information (not just simple data) at the desired level of scale and detail for a particular stakeholder’s view - information which once collected can be stored and refined and then held for use elsewhere on the project without loss and without the need for subsequent re-entry. The information needs to be available quickly and easily, that is at the right time and in the right location for maximum benefit and project efficiency. Demonstration collaborative systems to support interactive Computer Aided Design and information exchange between project stakeholders such as architects, various engineers (electrical, hydaulic, mechanical, structural) and project managers, in an innovative collaborative manner have become available to bring dispersed project members together electronically. Such systems allow project members attached to a network to undertake a range of information access and exchange from simple e-mail; through on-site access to central project data sources via handheld computers; right through to the use of optional live (or pre-recorded) video to enhance collaboration. Using communications infrastructure, this functionality can be shared in various ways - in a corporate-wide environment between regional and/or interstate offices within a company, or in a consortium situation (between offices of a consortium working together on a specific construction project). The questions then arise as to how such systems fit into industry practice, and how the industry might adapt to embrace new opportunities provided by such technological advances. Ease of access to up-to-date, accurate project information for a range of project stakeholders is being extended through research in the US and Australia to close the loop between some of the stakeholders, and this will be discussed in detail in the paper. As well, the progress of industry-based support for a level of interoperability for building and construction information by organisations such as the International Alliance for Interoperability (IAI Australasian chapter) will also be discussed, plus the likely impact of the adoption of Industry Foundation Classes in the Australian building and construction industry in areas such as the design life for buildings based on durability of materials.

Industrial case study of innovative managerial control system applied to site control process (IMCS-CON)

Abstract: Construction projects are complex, fragmented and highly risk business, due to the nature of construction operations. Therefore project managers require more efficient techniques and tools to plan and monitor the construc-tion project. In recent years many research studies have been carried out in order to make construction industry more efficient, profitable and attractive business. The IMCS-CON developed as decision support system for project mangers to assist project-controlling processes using a holistic approach. The IMCS-CON provide a framework to measure, analyse, review, and report performance data and enabling project management team to make corrective decision and keep project on track. The IMCS-CON system was evaluated using a case study of £2.3 million, three-story residential apartment building project in UK. The IMCS-CON system utilises multivariate statistical process control techniques to monitor the construction site variables. The MSPC combines a large number of variables into few independent vari-ables, which then can be monitored and any process deviations from the normal operating conditions can be identified with corrective actions suggested. The IMCS-CON models on-site information as quantitative variables and uses his-torical data and establishes patterns of correlated variables and assists project management in making future decisions. The outputs can also be visualised in multi-dimensional graphs. Statistics of external variables and internal variables influencing construction site operations were identified using a real life case study. The results of modelling the vari-ables and conducting experiments with IMCS-CON are analysed and discussed in this paper.

INTEGRATING TRUST CONCEPTS IN A DASHBOARD INTENDED FOR THE BUILDING CONSTRUCTION COORDINATOR

Abstract: The growing complexity of AEC projects leads to increase the importance of the building construction coordinator’s role. Moreover, the uncertainty linked to the environment of the building construction activity makes way for the notion of trust. The coordinator canmake use of a multiple tools/views for accomplishing his mission (e.g. planning, meeting report) but these views offer only a limited vision of the cooperation context. So we suggest analyzing data coming from these different views to obtain some trust indicators informing the coordinator about trust in the good progress of the building construction activity. Our approach distinguishes 4 aspects of the activity conditioning the global trust level: task progress, actor’s performance, documents required to perform the task, and building elements resulting from the task. Our proposal suggests introducing these trust indicators in a dashboard included in a multi-view interface allowing the coordinator identifying the tasks with a low level of trust and understanding the nature of the potential dysfunctions.

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.

Keywords: strategic advantage; IT-strategy; corporate strategy; impact of IT, European construction
