The construction industry has long faced challenges such as low production efficiency, unclear information communication, and information loss during project execution. Compared to other sectors, the level of digitalization in construction remains relatively low. To accelerate the industry’s transformation and boost overall productivity, Building Information Modeling (BIM) technology has been introduced and widely promoted in recent years.
The concept of BIM originates from product modeling in the manufacturing industry. BIM-based information models encompass various elements such as product composition, functionality, and activity data, representing the product throughout its entire lifecycle. Throughout a construction project’s lifecycle, BIM integrates a series of information processes—including data collection, management, exchange, updating, and storage—with project workflows. This integration provides stakeholders with accurate, timely, and sufficient information at every stage.
By enabling seamless information exchange and sharing across different construction phases, participants, and software platforms, BIM enhances the utilization and efficiency of information during design, construction, and operation. This not only ensures quality at each phase but also continuously improves productivity within the construction industry.
BIM serves as a data-driven, shared model that facilitates project management among all stakeholders. It can be understood on three ascending levels: the BIM information layer, BIM modeling, and management.
First, BIM relies on extensive data support covering the entire project lifecycle. This includes not only dimensions and location details but also information on material types, manufacturers, quantities, performance characteristics, and more. Importantly, this data integrates contributions from all parties involved, ensuring completeness, comprehensiveness, and interrelation.
Second, a BIM model is created by systematically combining the various types of project information into a unified, coherent whole. This modeling process can be seen as organizing information in an orderly fashion.
Finally, the management team utilizes specialized BIM software to apply various functions to the assembled model. For example, components can be displayed in chronological order to simulate construction sequences, thereby guiding construction activities and supporting effective project management.
