Contractors responsible for the whole execution of engineering, procurement, and construction
(EPC) projects are exposed to multiple risks due to various unbalanced contracting methods such
as lump-sum turn-key and low-bid selection. Although systematic risk management approaches
are required to prevent unexpected damage to the EPC contractors in practice, there were no comprehensive
digital toolboxes for identifying and managing risk provisions for ITB and contract
documents. This study describes two core modules, Critical Risk Check (CRC) and Term Frequency
Analysis (TFA), developed as a digital EPC contract risk analysis tool for contractors, using artificial
intelligence and text-mining techniques. The CRC module automatically extracts risk-involved
clauses in the EPC ITB and contracts by the phrase-matcher technique. A machine learning model
was built in the TFA module for contractual risk extraction by using the named-entity recognition
(NER) method. The risk-involved clauses collected for model development were converted into a
database in JavaScript Object Notation (JSON) format, and the final results were saved in pickle
format through the digital modules. In addition, optimization and reliability validation of these
modules were performed through Proof of Concept (PoC) as a case study, and the modules were
further developed to a cloud-service platform for application. The pilot test results showed that risk
clause extraction accuracy rates with the CRC module and the TFA module were about 92% and
88%, respectively, whereas the risk clause extraction accuracy rates manually by the engineers were
about 70% and 86%, respectively. The time required for ITB analysis was significantly shorter with
the digital modules than by the engineers.
