Utilizing an integrated AHP-Fuzzy Logic approach to develop a claims control tool for construction projects in Jubail City

Abstract

Abstract :The construction industry is a major sector in Saudi Arabian economy, particularly during the last 50 years. However, along with rapid construction and massive projects, 70% of the construction projects in the Kingdom of Saudi Arabia (KSA) suffered major delays and cost overruns. These delays in many projects were mainly due to unresolved claims. Unfortunately, claims have become an inevitable routine for both the contractor and owner. Due to claims’ complexity and the lack of clear mechanisms to efficiently predict and monitor claims, they are often tedious disputes causing major work interruptions, delays, and even project halt. A review of the literature with 189 case studies for construction projects in the city of Jubail revealed a need for more advanced project management tools to better monitor ongoing projects and reduce claims occurrences. Therefore, we developed for this study, an integrated claim control tool that quantifies project technical and financial status to predict possible claim formation and alert project managers and decision-makers. We used the analytical hierarchy process (AHP) integrated with a fuzzy logic, rule-based method to develop this tool, which includes financial, schedule, quality, safety, and risk status modules automated with Excel spreadsheets. This claim control tool provides a continuous comprehensive overview for project status using specific criteria and key performance indicators such as the project performance index and claim risk status to detect the possibility of claim formation. Being validated and tested by experts in the field, this study offers a distinguished integrated project management tool for any construction project that could be used by different management levels as a solid decision support system tool.
