BIM and big data complement each other in construction quality management, working together to enhance both construction quality and the efficiency of quality management processes.
First, the construction industry generates vast amounts of data, yet due to its low level of informatization, most quality management data remains scattered and fragmented. This fragmentation makes data collection and storage a significant challenge, hindering the effective use of big data. BIM technology serves as a crucial tool for information management within the construction sector, enabling front-end data collection and back-end data integration. BIM encompasses detailed engineering information for all components and equipment, as well as management data related to quality, schedule, cost, and safety. This creates a comprehensive data model that facilitates data generation, integration, storage, and sharing.
Moreover, a key obstacle in applying big data is the lack of accessible data resources. Quality management data, generated as a byproduct of BIM-based quality management processes, reduces the costs and difficulties associated with deploying big data solutions compared to systems designed specifically for big data collection.
Second, BIM acts as an information integration platform, providing a collaborative workspace for various project stages, participants, and specialties throughout the project lifecycle. This fosters quality management centered around information models. However, current BIM implementations often lack a comprehensive strategy for managing project lifecycle information.
Big data technology helps uncover hidden patterns within quality management data by mining existing datasets. This process establishes standardized data structures for BIM-based quality management and sets criteria for data collection and storage. Additionally, based on the needs identified through data mining, information collection and storage standards can be developed to support quality management workflows effectively.
Third, BIM technology transforms construction quality management by turning data into valuable information assets. In BIM-based quality management, older data is continuously updated while new data accumulates rapidly, leading to explosive data growth. Without effective tools for data extraction and analysis, valuable knowledge can be lost within this vast information pool, limiting support for quality management and wasting valuable assets.
By applying big data analytics and strategically utilizing information resources, quality issues can be identified and mitigated. This enhances the predictability and control of quality management processes, ultimately delivering economic benefits to construction projects.
Within BIM-based construction quality management, each piece of quality data uploaded is associated with specific information such as location and time. Although data types are diverse and updates occur rapidly, at the component level, each quality record is linked to a component via an ID. This information is dynamically collected, updated, and refined throughout all project phases—from design and construction to completion, acceptance, and operation—ensuring timeliness and traceability. This process naturally results in the generation of massive datasets.
As BIM technology sees widespread adoption, the volume of quality management data will continue to grow. Big data analysis techniques can then be applied to extract value from this data, solidifying quality management experience and lessons learned, and providing a robust foundation for decision-making in future projects.
The synergistic relationship between BIM and big data, alongside their respective quality management models, outlines the pathway for implementing these technologies in quality management. The application of BIM and big data in construction quality management primarily aims to achieve the following goals:
First, enhance the predictability and control of construction quality management while improving work efficiency. Mining big data unlocks hidden knowledge, gradually forming an ontology-based quality management database for construction projects that supports informed decision-making. Simultaneously, BIM technology assists in optimizing quality workflows by enabling dynamic, real-time tracking of quality. This results in more precise management, increased predictability, and better control, providing strong support for meeting quality objectives and enhancing efficiency.
Second, improve overall construction project quality. By analyzing data related to quality issues encountered during management processes, common and unique problems can be identified. This data-driven insight supports both preventive control and post-project improvements. BIM facilitates construction simulation, rigorously controlling quality factors from the perspective of 4M1E (Man, Machine, Material, Method, Environment), guiding construction activities and enabling real-time monitoring. Strengthening quality control and assurance through these methods reduces defects during construction and leads to higher quality results.
