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."

Concurrent engineering in the tendering process of building and construction

Abstract: CONCUR (Concurrent Design and Engineering in Building and Civil Engineering) is a four year initiative in the European Union Brite-EuRam workprogramme involving industry partners Skanska (Se), IVO Power Engineering (Fi) and Taylor Woodrow (UK), the specification body STABU (Nl), R and D institutions VTT (Fi) and TNO (Nl), and universities DUT (Nl) and KTH (Se). The project will develop, implement and industrially deploy an integrated CAx environment for concurrent construction tendering. CONCUR is addressing the integration of information in the stages which lead to submission of tenders. The goal is to reduce tendering cost by 30 - 50% using integrated information systems and applications. The tendering process is a complex process involving many disciplines each of which uses different types of information. . In essence it is an information refinement process, in each refinement cycle addressing the high risk aspects of the moment. In CONCUR we are addressing the integrated use of information and applications, using Project (Product and Process) Data Technology Using the major informational items the refinement process will come to information specifications. The specifications being derived are not re-invented but use is made of existing and emerging standards such as STEP and IAI. Results of the CONCUR efforts can be fed back to STEP and IAI.
