Abstract

Management of running costs to approach productivity indices between planned and actual is an important topic for BIM-based cost management systems. In the context of conventional BIM management, it is expected to get more detailed models as the design decisions developed. On the other hand, in the complex structure of project deliveries, where the construction phase is started and the design decisions are not completed yet, alternative procedures are required to manage outputs for both early and detailed stages of the design in the same model environment. In this chapter, the M9 Ikitelli-Ataköy underground line project was analyzed to decide the most proper scheduling workflows to generate survey reports of confined wall systems. While the length value is required to estimate cost alternatives of interior cladding, bill of quantities are going to be measured for calculation of surface area completed from the same model assembly. On the contrary, the system is assembled with both architectural and structural model elements, thus, the measurement data from length and area values cannot be pulled out to table list by default scheduling features of modelling software. When the BIM model elements hold the data, but those can not be inferred as required information, alternative information acquirement methodologies were reviewed and compared. During the study, the scope of BIM ontology was formed by such BIM platforms as Revit and its associated extensions Dynamo and Roombook. At the end of the study, it is aimed to present practical advantages of extensions at the automation of cost estimation and preparing bill of quantities in the BIM environment.
