||There is an increasing realisation of the importance of operation andmaintenance as opposed to capital costs throughout the life of an asset. Inaddition, new styles of contracts such as PFI (Private Finance Initiative) arebecoming more popular. This will require that the building product isaddressed within its holistic picture including the design, construction andmaintenance. It is therefore vital to embed the life cycle costing element ofa facility within its design and construction. Whole Life Costing is atechnique used to facilitate effective choice between alternatives in thesearch of economic solutions. Information technology, particularlyintegrated databases and VR (Virtual Reality), can provide the mechanismto facilitate the integration of the whole life cost information. The researchproject described in this paper aims to add a life cycle costing element to thedesign phase of the OSCON integrated database developed at SalfordUniversity in the UK. The current integrated database within OSCONsupports the functions of design, estimating and planning. The proposedsystem will allow the user within a VR environment to navigate inside thebuilding retrieving information about building components that needreplacement or repair. A colouring mechanism will be developed to showvarious elements in different colours according to cost criteria. This wouldallow the user to easily inspect the building and get rough ideas of repairand maintenance programmes, running costs and cash flows. The systemwill allow data to be updated continuously so that it will enable thecomparison with initial plans and estimates and provides a fresh view offuture action and feedback.
