Steel structure engineering primarily utilizes steel as its main material and is one of the main types of building structures. Steel structures are one of the more common structural forms in modern civil engineering. China is a country that has historically used iron to manufacture load-bearing structures. Iron was first used in the creation of simple load-bearing structures. Western countries did not begin using metal load-bearing structures until the 17th century.

We understand that steel structure construction involves two stages: factory production and on-site installation. These stages can be carried out by a single contractor or, sometimes, by two separate entities (subcontractors). Proper selection and inspection of manufacturers and installation units are crucial for ensuring the quality and progress of steel structure projects. The inspection content for steel structure production and installation units primarily includes: company qualifications, production scale, number of technical personnel and their titles/resumes, number of skilled workers and their qualifications, machinery and equipment, and performance levels.

Construction organization design is a crucial comprehensive technical document prepared by contractors to guide all activities throughout the entire construction process. Thoroughly reviewing the construction organization design is an important aspect of pre-control and proactive control in supervision work. For steel structure projects, separate production phase and installation phase production processes and construction organization designs should be prepared. The production process content should include quality standards and technical requirements for each operation in the production phase, various sub-items, and various specifications formulated to ensure product quality. Specific measures, such as processing methods for key components, process flow and measures for main components, as well as the processing and production equipment used.
