What Are the Full-Process Applications of BIM Technology in GRC Engineering Projects? Digital-Driven Lean Construction

BIM (Building Information Modeling) technology has been deeply integrated into the full lifecycle of modern GRC engineering projects, playing an irreplaceable role from early design schemes to later operation and maintenance. Qinglong Group, as a pioneer in digitalization practices within the industry, summarizes the application of BIM technology in GRC projects into the following five core stages.

1. Scheme Design and Detailed Development Stage: At this stage, BIM serves as the "translator of design" and the "detector of problems". We receive the architect's creative models (often free-form surfaces created in software such as Rhino) and import them into BIM platforms such as Revit for detailed development. The work includes: performing rationalization analysis of complex curved surfaces and optimizing panel grid dimensions to ensure components can be produced and installed; conducting structural load analysis to determine panel thickness, stiffening ribs, and embedment positions; and carrying out clash detection with other disciplines such as MEP and lighting to resolve pipeline conflicts and reserve installation space in advance.

2. Mold Design and Production Stage: BIM is the "commander of manufacturing". The geometric information of the fully developed GRC component BIM models can be directly exported as machining code for CNC machine tools, driving equipment to precisely manufacture molds—achieving "model as mold" with errors controlled at the millimeter level. Meanwhile, information in the model (such as component ID, volume, and weight) can automatically generate a Bill of Materials (BOM) to guide production planning and material procurement.

3. Construction Simulation and Schedule Management Stage: BIM is the "rehearsal stage of construction". Using 4D BIM (model + time), the installation sequence and hoisting paths of the entire GRC curtain wall can be simulated to optimize construction plans and identify conflicts in installation procedures in advance. For the Hainan Convention and Exhibition Center project, we optimized the installation workflow through construction simulation, improved the utilization efficiency of large hoisting equipment, and shortened the construction period.

4. On-site Installation and Quality Control Stage: BIM is the "navigator on site". BIM models are imported into total stations, layout robots, or tablets to guide precise on-site setting-out and installation positioning. Installation personnel can view the 3D model in real time to clearly identify the position and number of each panel. Installation data (such as deviation measurements) can be fed back into the model, enabling visual traceability of quality.

5. Operation & Maintenance and Asset Management Stage: BIM is the "medical record of the building". The as-built BIM model is delivered to the owner, integrating the production information, installation information, and maintenance records of each GRC component. When inspection, cleaning, repair, or replacement is needed in the future, components can be quickly located and relevant information retrieved, achieving refined, information-based facility management.
