Features: This quota was formulated in accordance with the requirements of the Ministry of Construction's Standard and Quota Department's "Letter on Organizing the Compilation of the 'National Unified Installation Engineering Basic Quota'" (Jianbiaozaohan [2004] No. 66), adhering to scientific rationality and practicality. It serves as a basic reference for government investment project construction, provides a reference for all parties involved in calculating project costs, and meets the needs of bill of quantities pricing as well as facilitating the preparation of composite unit prices in tenders and bids. During the compilation process, the quota summarized the experience of the "National Unified Installation Engineering Basic Quota" (draft for approval) compiled in 1995 and the "National Unified Installation Engineering Budget Quota" of 2000. It is based on the current national construction and acceptance specifications, technical operation procedures, quality evaluation standards, and safety operation procedures. The quota was compiled according to the commonly used construction methods of domestic construction enterprises, reasonable labor organization, and normal construction conditions. Before the approval and release of this quota, opinions were widely solicited from relevant construction units, project owners, and cost engineering management departments across the country, and it passed a national review meeting attended by relevant experts. The Ministry of Construction is responsible for the management of this quota, and the Standard and Quota Research Institute of the Ministry of Construction is responsible for the interpretation of its specific technical content. This quota is divided into nine specialized fields, including: welding, cutting, beveling, painting, insulation, and anticorrosion, inspection, testing, purging, and cleaning, hoisting and horizontal transportation, piping assembly and installation, equipment fabrication, assembly, and installation, and furnace and kiln masonry engineering, as well as electrical equipment and automation control instrument installation engineering.
