BIM Hierarchy Generation for Faster Multi-Model Facility Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring building information models (BIMs) is a time-consuming process, and existing BIM software has limitations such as allowing manipulation and presentation of only one BIM file at a time, making it difficult for users to understand and manage BIMs effectively.
Innovation Solution
A system and method that automate the configuration of BIMs by obtaining BIM data, identifying BIM objects and their relationships, applying semantic descriptions, and generating a hierarchy structure, which includes mapping BIM objects to points in a building automation system (BAS) and presenting the data through a user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated configuration is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The system performs automated configuration of BIM files by self-identifying BIM objects, extracting metadata, determining relationships between objects, and generating hierarchy structures without requiring manual user intervention for each step, thereby improving productivity while managing complexity through automation
Solution Approach 2:
The configuration process is divided into distinct functional modules: BIM object identification, metadata extraction, relationship determination, semantic description application, and hierarchy structure generation. This segmentation allows each module to be developed and maintained independently, managing overall system complexity
2Adaptability or versatility
If multiple BIM files are integrated, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system is designed to handle multiple BIM files from different sources and formats simultaneously, applying the same configuration process and hierarchy generation logic to each file, making the system versatile in handling various BIM scenarios without requiring separate processing paths
Solution Approach 2:
The system introduces an intermediary hierarchy structure that acts as a mediator between multiple BIM files and the final integrated representation. This hierarchy structure standardizes the organization of BIM objects from multiple files, making integration manageable despite the complexity of handling multiple sources
3Manufacturing precision
If manual configuration is used, then manufacturing precision is maintained, but loss of time increases
Solution Approach 1:
The system extracts metadata from BIM files and uses this feedback information to automatically determine object relationships and generate accurate hierarchy structures. The semantic descriptions provide feedback that ensures configuration accuracy while eliminating manual time-consuming steps
Solution Approach 2:
The system performs preliminary extraction of metadata and identification of BIM objects before the main configuration process. By preparing the hierarchy structure and relationships in advance through automated analysis, the system ensures accuracy is established early while saving significant configuration time
Data Source
AI summary
A system includes one or more memory devices having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations including receiving building information model (BIM) data associated with a building comprising one or more building assets, identifying one or more BIM objects within the BIM, identifying one or more object relationships between the one or more BIM object, applying a semantic description to each of the one or more BIM objects and the one or more object relationships, and generating a hierarchy structure for the building based on the one of more BIM objects and the one or more object relationships. The one or more BIM objects are associated with the one or more building assets and the hierarchy structure includes the semantic description of each of the one or more BIM objects and the one or more object relationships.
