| Abstract |
Recently the functions of public office building have changed into multi-purpose types, such as residential culture, welfare, lease and others as well as public administration services. This diversification of functions has brought the enlargement of the public office building and the increase of construction costs compared to the past. Especially, the MEP(Mechanic, Electric, Plumbing) construction costs are expected to increase by the application of building automation system, intelligent system and energy saving system. the MEP costs of the public office building account for 33.94% of the total construction costs averagely. Therefore, the demand of an appropriate cost estimating and management has increased, the controversy about the reasonable costs of the public office building has been growing steadily. However, most of researches on cost estimating model for construction focused on the overall construction, frame work and finishing work. This study suggests CBR(Case Based Reasoning) based MEP Cost Estimating Model which is estimating by selection of main works and impact factors. 16 Main works and 28 Impact factors were provided through analysis of the construction costs of 19 public office building projects. The proposed model will facilitate the estimating of MEP cost in the basic design stage by project owner or architect, and proves cost estimating accuracy of the Model for the case. |
