Integrated Cost Management between BIM (Building InformationModeling) and ERP Systems

Abstract

This study comprehensively examines the integration of BIM (Building Information Modeling) and ERP (Enterprise Resource Planning) systems, which aim to holistically carry out cost management and resource planning in construction projects. While BIM-based models present detailed geometric and parameter data of building elements, ERP systems effectively manage corporate functions such as accounting, supply chain and stock management. Data exchange between the two systems increases accuracy and transparency in project planning, allowing early detection of cost deviations. In addition, communication between stakeholders from different disciplines (architects, engineers, finance experts, etc.) over a common database increases data consistency and reliability of reporting.

The research discusses the effects of BIM-ERP integration on cost management with a case study method, through three different construction project examples: Horizon Towers Integrated Complex, Green City Urban Renewal Project and Skyline Infrastructure Development. The methodology used included technical performance of inter-system integration modules, cost variances, time management and qualitative data analysis; Thus, the financial and operational benefits of digitalization in the construction industry have been comprehensively evaluated. The study’s findings reveal that, beyond traditional methods, digital integration is a critical element that increases efficiency in construction projects, making significant contributions to accelerating decision-making processes and optimizing resource use.
