The original beams, columns, floors, and window frames of the old factory building could not be altered. The entire process used prefabricated partitions made of machine-made color steel cleanroom panels to divide the area. The modular assembly achieved physical separation between clean and contaminated areas, strictly following the logic of separating clean and contaminated flow of people and materials, without damaging the original main structure of the building, and is compatible with general clean and contaminated separation standards such as GMP, electronic cleanrooms, and food purification.

The visitor access route to the biopharmaceutical workshop has an independent layout and does not pass through the clean production area. The core design logic is that the visitor access route is set as an independent outer perimeter corridor, which is completely isolated from all clean production areas by solid partitions and sealed doors. The flow of people is completely separated from the flow of people and materials in clean production, with no intersections, crossings, or shared buffers/changing rooms/airlocks. At the same time, it meets the requirements of GMP, biosafety, and personnel flow separation.

Pharmaceutical manufacturing has extremely high requirements for environmental cleanliness. As a legally mandated standard in the pharmaceutical industry, Good Manufacturing Practice (GMP) aims to eliminate particulate contamination, microbial contamination, and cross-contamination at the source through standardized cleanroom environmental management, thereby ensuring drug quality and safety and production compliance. GMP cleanrooms are the core setting for pharmaceutical production, and their environmental management is not simply about cleaning and sanitation, but rather a standardized, traceable, dynamic, and continuously validated system management framework.

Airborne dust, microorganisms, and fine particulate matter may not affect daily life, but they can severely disrupt production processes in industries such as precision manufacturing, pharmaceuticals, and cosmetics. Tiny impurities can cause electronic component malfunctions, product contamination, and quality degradation. ISO 8 cleanrooms are standardized clean production spaces built according to international standards and are currently the most widely used medium-cleanliness environment in the industrial sector.
