Possibilities to control life-cycle costs of buildings are greatest in the very early building planning phases. However there is lack of reliable cost estimation tools for early planning phases. In this project has been implemented simple costing tool prototype based on the neuralnetwork technology. The costing tool was accessed with the STEP input/output off-line link to the common design database of the COMBINE 2 project.
The Costing Tool is programmed with the commercial NeuroWin neuralnetwork tool and the user interface is programmed with the VisualBasic programming tool.
