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."

Message development in the building process

Abstract: New communication media offer new opportunities to exchange information between participants in a building project. A case study was done of a specific building project from the viewpoint of a company that produces concrete floors. An executable simulation model was used to create a formal description of the information exchange process. The output of the simulation is an activity schema, a message exchange diagram and a list of messages. The schemata give insight about the information flow and are a resource for developing a strategy for the introduction of electronic communication. The messages serve as a starting point for selecting a standardized electronic message or developing a special one.

Risk assessment in disaster recovery strategies development

Abstract: The paper describes the model for selecting disaster recovery strategies for information system. The risk assessment covers the threats and vulnerabilities related to the problem of losing the availability of information processes in the particular information system model. The analysis takes under consideration the relationships between the components of information system in order to find the risk of availability lost propagation within the system. That is the basis for finding the candidate disaster recovery strategies, which have to fulfil these basic requirements. Such an approach allows sifting these ones, which are basically not suitable for the security requirements of the information system. The preliminary accepted strategies are to be analyzed regarding to the estimated cost of implementation and maintenance. The next phase covers the detailed analysis of confidentiality and integrity risks in the candidate strategies. The level of risk related to the confidentiality and integrity of information processed in the disaster situation using given strategy is to be estimated.

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).

Shifting the construction interoperability paradigm, in the advent of Service Oriented and Model Driven Architectures

Abstract: A major difficulty construction companies are currently facing is the lack of interoperability of software applications to manage and progress in their business. Organizations are being pressured up by new business relationships, driven for instance by new contractual challenges, which the exchange of information and documents with new partners are often incapable of being executed automatically and in electronic format. This is principally due to problems of incompatibility with the information representation adopted by the software applications they are working with. This problem arises not only during the project phase but also across the whole life cycle that includes operation and maintenance stages. In order to create the enabling conditions for the deployment of the electronic collaborative and commerce platforms it is fundamental to understand the variables that may influence its development, and how they determine the configuration of the e-platform. This paper, after present technology driven standards for the construction industry data management, it proposes the adoption of the emerging Service Oriented and Model Driven Architectures to shift forward the interoperability paradigm in this industrial sector. The paper illustrates some scenarios where significant impact is expected when adopting the proposed methodology.

ADVANCING THE USE OF BIM THROUGH A GOVERNMENT FUNDED CONSTRUCTION INDUSTRY COMPETENCY CENTRE IN IRELAND

Abstract: The main aim of this paper is to develop the early case for a new Competence Centre dedicated to industry led research in the Irish construction industry. It incorporates the results of a survey carried out by the Construction IT Aliance (CITA) and also identifies similiar centres carrying out industry led research around the world. Results from the survey show a clear support for the establishment of such a centre in Ireland and, in particular, a strong interest in Building Information Modelling (BIM) as a immediate priority research area. BIM is having a profound effect worldwide on the construction industry. The development and adoption of BIM technologies is in parallel with other major changes relating to project procurement approaches, such as Integrated Project Delivery (IPD), and the general sustainability agenda. Although slow to take off in Ireland to-date, BIM is becoming extremely relevant in other countries, with over 50% adoption in the United States and an average of 36% in Europe. The authors argue that a government funded Competence Centre will facilitate the Irish construction industry in re-establishing itself, domestically and internationally as a competitive entity.

Integration of Multiple Product Models

Abstract: The development of the Industry Foundation Classes (IFC) started from the vision that an integrated building product model would cover all necessary information for a buildings’ entire lifecycle: from requirements management, through different design processes to construction and maintenance processes. Although the IFC model specification covers a substantial part of the required information, AEC projects still have encountered many problems putting this model into practice. AEC professionals still find it difficult to have dynamic, lossless, truly effective data flow amongst the different participants and applications. It is obvious that file based data exchange alone is not a feasible solution - some other solution for integrating project information is necessary. This workshop discusses some viewpoints and potential solutions to the above issues and problems.
