Omission Inspection Support System for Construction Contracts: Case Study in Public Construction Project

Omissions in construction contracts are a common source of disputes in the construction industry. In Taiwan, claims related to contract omissions have amounted to over NT$200,000,000 in the past decade. Although standard procedures exist to prevent omissions, manual inspections rely heavily on the expertise and judgment of professionals. Furthermore, due to the time constraints associated with bidding, inspectors may overlook details or skip steps, resulting in potential omissions. This case study focuses on the development of an omission inspection support system to enhance the efficiency and accuracy of contract inspections in Taiwan’s construction industry. Patterns of omission were redefined using past court judgments in Taiwan and served as the foundation for system development. The system’s effectiveness was validated through a scenario-based user test involving real-world cases from Taiwan’s public construction projects. Results demonstrated that using the system reduced inspection time by at least 90% compared to the manual process, with a 50% increase in accuracy. These findings suggest that the developed system can significantly improve the omission inspection process. It is anticipated that this system will help mitigate risk factors associated with omissions in public works projects during the early phases, thereby reducing future disputes and lowering associated costs.
