1. Familiarize yourself with the structure of the old factory. As we all know, each era has its own differences in construction materials or techniques. In the 1970s, industrial production factories were predominantly built using brick and concrete or an inner frame system, with very few being pure frame structures. Only by thoroughly understanding the original factory's structure can we combine experience to transform its functions.

2. Inspect the factory's damage and corrosion. Each factory produces different products; for instance, chemical products can be corrosive. Pay close attention to walls, columns, beams, and other structures to prevent weakening of components or loss of load-bearing capacity.

3. Familiarize with the design standards of old factory buildings. Understanding this is crucial as it serves as the basis for component strength. During the use of the factory, continuous repairs and renovations are made, with the standards gradually increasing. For instance, the current engineering and construction projects are more stringent in terms of structure and seismic ratings compared to the old regulations. Therefore, the design of old engineering buildings was effective at that time, but it is uncertain if they meet the current standards and regulations.

4. Conduct a preliminary assessment of the old factory. It is imperative to engage a specialized assessment center to effectively inspect the abandoned factory, providing reliable data for renovation and determining the grade, to prevent potential safety hazards due to lack of experience among technical personnel or inadequate assessments.

5. Design. We should first create an initial plan, selecting the level, materials, and costs based on the future role. The design must be well-organized, with funds allocated moderately to avoid repeated use of labor and materials.

6. Materials. Initially, in the selection of materials, we recognize that the current basis for decoration is the assembly line method. However, we can still explore more on our own, which allows us to understand the market and find suitable products and prices for ourselves. Since materials represent a significant expense, fake products are abundant, so it is crucial to be cautious and avoid purchasing unbranded items to prevent buying counterfeit goods.

7. Renovation Quotation, Valuation, and Contract Signing for Old Factory Buildings. After exploring prices across several markets, conduct a comparative analysis to identify a suitable option. Consult with professional personnel before finalizing the contract, ensuring reliability. The contract should include details such as materials, brands, and prices; the more specific, the better, to prevent future disputes.

8. Time Preparation. Due to the large area of the renovation, the expenses will undoubtedly be substantial. Therefore, we must be fully prepared in advance, including time, design, materials, and costs. The more thoroughly we prepare, the faster the renovation process will progress.
