Development of an Ontological Cost Estimating Knowledge Framework for EPC Projects
This research standardizes a knowledge structure for estimation in the construction field by creating a method to enhance cost management efficiency of construction projects while meeting the need for reusability of accumulated construction information. The construction knowledge structure was developed to execute the project cost estimation with an ontological concept. The knowledge framework was defined and relevant examples were addressed to explain the structure. The detailed estimation process and methodology for using standard unit price information was also developed to strengthen cost information interoperability by utilizing standard classification systems, such as MasterFormat, UniFormat, UniClass, and ISO 12006. This concept may be proposed as a method of connecting construction information based on a standard cost classification system in order to improve estimation efficiency by increasing the connectivity of cost information. Ontology can be a powerful tool when used in conjunction with interoperability to manage the massive volume of construction information for cost management. This methodology can expand to integrated management in cost and time to derive additional classes for work breakdown structure (WBS). Thus, ontology may improve the efficiency of cost estimation and systematization by reusing construction information. As a further step, the interoperability method will enhance overall construction project management.
