Semantic Integration of Cost, Time and Geometry for a Resource-Centred Perspective of Managing Construction Projects

For project success, time and cost must be continuously balanced based on resource utilization. However, resources are usually planned implicitly and not aligned between scheduling and cost estimation, leading to inconsistencies in project management processes. To address this issue, this paper proposes a resource-centric approach that integrates building geometry with schedule and cost data using ontologies as the semantic foundation. A web prototype converts and links the original data into an RDF graph, enabling advanced SPARQL queries for cross-domain consistency checks, particularly on resource usage. These checks validate the alignment of interconnected project domains, providing insights unattainable with traditional methods.
