2. Construction enterprises can apply for one qualification at a time, or apply for multiple qualifications at the same time.
3. Enterprises must first apply for low-level qualifications, and only after the project performance of enterprises meets the requirements of high-level qualifications and the relevant technical personnel and registered capital meet the minimum requirements can they apply for qualification upgrading.
Construction companies should pay attention to many problems in handling construction qualifications, so companies generally choose qualification agencies to handle construction qualifications. Personally, I suggest that Shandong Hejia has a good reputation in the industry and its services are comprehensive.
