Currently, the development of BIM-related technologies can be broadly categorized into three main areas: information exchange standards, modeling techniques, and model operation technologies:
(1) Information Exchange Standards:
BIM software often requires converting and integrating model files, where the most widely used standard is the IFC (Industry Foundation Class). IFC is specifically designed to facilitate information exchange throughout building planning, design, construction, and management phases. Another important standard is CIS/2 (CIMsteel Integrated Standard – Version 2), which is applied in structural steel design and manufacturing. Both standards define product geometry, component relationships, construction processes, materials, performance criteria, and manufacturing details.
(2) Modeling Techniques:
Leading BIM modeling tools include Autodesk’s Revit series, Bentley’s MicroStation and ProjectWise, Graphisoft’s ArchiCAD, and Tekla. These platforms utilize a technology similar to the “Parametric Change Engine” (a term coined by Autodesk Revit), which allows for intelligent, interactive adjustments of spatially related components. Behind the geometric models, associated attribute data is managed by independent database engines capable of handling complex model information.
(3) Model Operation Technologies:
BIM technology encompasses comprehensive information management and application covering both the “form” (geometric data) and the “meaning” (non-geometric data) throughout the engineering lifecycle. Key factors such as model presentation efficiency, aggregation and manipulation of attribute data significantly impact BIM operation quality. Presently, BIM operation techniques focus on enhancing software and hardware performance through 3D visualization, conflict analysis and verification in space and time, cloud services provision and utilization, interdisciplinary collaboration, and seamless integration and delivery across project stages.
