Technology Ontology and BIM-enabled Estimating for Owners and Contractors

摘要

A database of construction methods can help select the optimal approach to building a construction project. To be useful, such a database should be integrated with BIM, and thus, be based on a consistent methodology to define and classify construction methods. Contractors' are confronted with problems in selecting proper construction methods and applying their knowledge about specific and well-defined technologies to a project. This paper proves empirically that selecting the right methods using one of the technologies available for multiple activities would create accurate costs when not only materials are priced, but also right equipment and available labor. This way, owners can efficiently demand deliverables that can be utilized by them downstream, allowing Contractors and subcontracting trades to work efficiently and to assure the daily flow of operations.
