Abstract

Extensive research has explored BIM-based Quantity Take-Off (QTO), yet producing a practical Bill of Quantities (BOQ) for execution budgeting remains challenging, particularly for finishing works, due to complex information requirements and frequent project-specific variations. This study proposes a standardized property system and a BOQ-linked relational database schema to automate execution BOQ generation for large-scale apartment housing projects. The core contribution is a property-rule-mapping layer that structurally decouples BIM object data from cost items. This deterministic 1:N mapping approach intrinsically prevents rule conflicts and enables the system to adapt to changes in the Cost Breakdown Structure (CBS) or construction methods by updating database queries without modifying the source code. The approach was implemented in an in-house Revit-based system and validated across multiple projects from 2023 to 2025. Quantitative results demonstrate significant system stabilization as project data accumulated: the new rule creation ratio dramatically decreased from 13.63% to 0.53%, system errors were completely eliminated, and the rule stabilization index reached 99.47%. Scalability was further examined using the Korea Land & Housing Corporation (LH) library and heterogeneous BIM software. Despite differences in modeling standards, external data were successfully integrated through object decomposition and additional rule definitions alone, demonstrating high interoperability and supporting the model's potential as a reusable platform for construction cost management.
