Construction Data Management Using Design-Corrected BIM Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The utilization of BIM at construction sites is delayed, and there is a need for technologies that coordinate actual construction status with design data, manage data to reflect changes in upstream and downstream processes, and include members not initially considered in design BIM.
Innovation Solution
A data management system and method that involves databases for design, measurement, and construction data, allowing for the creation of design corrected models by synthesizing measurement and design models, and recording corrected construction plans with member coordinates and shapes, including movable member influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is distributed across multiple storage devices to improve reliability, then data loss risk is reduced, but management complexity and time increase
Solution Approach 1:
The patent divides data into multiple data strips and distributes them across different storage devices. This segmentation approach allows the system to maintain high reliability through distribution while managing complexity through structured organization of data blocks and their relationships across devices.
Solution Approach 2:
The patent introduces a management server as an intermediary that centralizes the management of distributed data. The management server handles reconstruction requests, coordinates data retrieval from multiple storage devices, and manages the overall data reconstruction process, thereby reducing management complexity for end users.
2Reliability
If data is distributed across multiple storage devices to improve reliability, then data loss risk is reduced, but reconstruction time increases
Solution Approach 1:
The patent pre-establishes the relationship information between data blocks and their locations on storage devices before data loss occurs. This preliminary organization allows the management server to quickly identify and retrieve the specific data strips needed for reconstruction without unnecessary searching, thereby reducing reconstruction time while maintaining reliability through distributed storage.
3Ease of operation
If all data is集中 stored on one device for ease of management, then management is simple, but data loss risk increases
Solution Approach 1:
The management server acts as an intermediary that provides centralized management functionality while the actual data resides distributed across multiple storage devices. This allows the system to maintain ease of management through a single management interface while achieving reliability through physical data distribution, effectively decoupling management simplicity from storage architecture.

AI summary
Data management to reflect an actual construction status in the upstream and downstream processes is realized. A management system according to the present invention includes a design database (21) recording design data of construction members, a measurement database (22) recording measurement data of the construction members, a construction database (6) recording construction data of the construction members, a construction member selecting unit (7), a peripheral member selecting unit (8) configured to select a peripheral member peripheral to the construction member, a model creating unit (9) configured to create a design model of the construction member and a measurement model of the peripheral member, a corrected model creating unit (10) configured to create a design corrected model by synthesizing the design model and the measurement model, and a corrected construction plan creating unit (11) configured to select a construction designated member based on the design corrected model, and record, with respect to the construction designated member, coordinates and a shape of the design corrected model as construction designated member coordinates and a construction designated member shape, and construction content of the construction designated member as construction inspection content, in a corrected construction plan database (12).
