Classification of Qualification Levels for Steel Structure Engineering Professional Contracting Enterprises

In the construction industry, the professionalism and complexity of steel structure engineering require enterprises engaged in related businesses to have corresponding qualifications. The classification of qualification levels for specialized contracting enterprises in steel structure engineering is of great significance for regulating market order and ensuring project quality. It also affects the positioning and development of steel structure manufacturers in the market, as well as the development of steel structure installation and other businesses. The professional contracting qualifications for steel structure engineering are divided into Level 1, Level 2, and Level 3.
The first level qualification standard requires that the net assets of the enterprise reach more than 30 million yuan, which reflects the strong economic strength foundation of the enterprise and can undertake large-scale and highly complex steel structure engineering projects. In terms of personnel, there are no less than 8 first level registered constructors in the field of construction engineering, which ensures that the enterprise has sufficient professional leaders in project management. They have rich engineering experience and comprehensive management capabilities, and can effectively organize and coordinate all aspects of steel structure engineering from design to construction. The technical leader must have more than 10 years of experience in engineering construction technology management, and hold a senior professional title in construction engineering. In the steel structure projects they have presided over and completed, their engineering quality is qualified. This requires the technical leader to have in-depth expertise and rich practical achievements in the professional technical field, and be able to provide strong support for the enterprise's technical research and development, scheme formulation, and quality control. The construction site management personnel shall not be less than 30, and the construction personnel, quality personnel, safety personnel, material personnel, cost personnel, data personnel and other personnel shall be complete. This reflects the refinement and standardization of the enterprise's construction site management, with dedicated personnel responsible for each position to ensure that the construction process is carried out in an orderly manner. There shall be no less than 50 intermediate or above professional and technical workers, including welders, painters, crane signalers, and other workers. These professional and technical workers are the direct executors of steel structure construction, and their skill level and operational proficiency directly affect the quality of steel structure production and installation.

In the past 5 years, the enterprise has undertaken more than 3 of the following 6 steel structure construction projects with qualified engineering quality, such as steel structure height of over 80 meters, steel structure single span of over 30 meters, grid shell, short side span of grid structure of over 50 meters, single steel structure building area of over 30000 square meters, and single steel structure engineering steel structure weight of over 5000 tons. This series of performance requirements indicates that first-class qualification enterprises have accumulated rich experience in past project experience and can cope with various difficult and large-scale steel structure engineering challenges.

In the second level qualification standard, the net assets of enterprises are required to be above 15 million yuan, which is lower compared to the first level qualification, but still provides economic security for undertaking projects of a certain scale. There shall be no less than 6 registered constructors in the field of construction engineering, and the technical leader shall have more than 8 years of experience in engineering construction technology management, and hold a senior professional title or a first level registered constructor qualification in the relevant field of construction engineering. The steel structure engineering quality completed by the principal shall be qualified. There shall be no less than 20 construction site management personnel, and all personnel including construction workers, quality inspectors, safety inspectors, material inspectors, cost inspectors, and document inspectors shall be complete. There shall be no less than 30 intermediate or above professional and technical workers, and their job types shall be similar to those with first level qualifications. In the past 5 years, the company has undertaken the construction of 3 or more steel structure projects among the following 6 projects, with qualified engineering quality, such as steel structure height of over 60 meters, steel structure single span of over 25 meters, grid shell and grid structure short side span of over 35 meters, single steel structure building area of over 20000 square meters, and single steel structure engineering steel structure weight of over 3000 tons. The second level qualification enterprise has lower scale and difficulty requirements than the first level qualification, but also has strong steel structure engineering construction capabilities.

Third level qualification standard, with a net asset of over 8 million yuan, no less than 3 registered construction engineers in the field of construction engineering, a technical leader with more than 5 years of experience in engineering construction technology management, intermediate or above professional titles or registered construction engineer qualifications in construction engineering related fields, and having completed at least 2 projects in this category with qualified engineering quality. There shall be no less than 10 construction site management personnel, and all personnel including construction workers, quality inspectors, safety inspectors, material inspectors, cost inspectors, and document inspectors shall be complete. There shall be no less than 15 intermediate or above professional technical workers, including welders, painters, crane signalers, etc. Can undertake the construction of the following steel structure projects: steel structure height below 60 meters, steel structure single span below 30 meters, mesh shell, grid structure short side span below 33 meters, single steel structure building area below 3500 square meters, single steel structure engineering steel structure weight below 3000 tons, etc. Third level qualification enterprises mainly target small-scale and relatively simple steel structure projects.

For steel structure manufacturers, the qualification level determines the scope of projects they can participate in competition. First level qualified manufacturers have more opportunities to showcase their strength in high-end projects such as large sports venues and super high-rise buildings; Second level qualified manufacturers can play a role in medium-sized industrial plants, commercial complexes and other projects; Third level qualification manufacturers focus more on basic steel structure projects such as small warehouses and simple factories. In terms of steel structure installation business, differences in personnel allocation, technical level, and construction experience among enterprises with different qualification levels can also affect installation quality and efficiency. High qualification level enterprises, with more professional teams and rich experience, can better cope with complex problems in the installation process, such as high-precision installation of large grid steel structures, wind and earthquake resistant installation of high-rise steel structures, etc., thus providing customers with higher quality and more reliable steel structure installation services, ensuring the smooth completion and long-term stable operation of the entire steel structure project.
