Division basis of partial projects: partial projects: according to the different division of engineering parts, the types and models of equipment and materials used. Examples: foundation engineering, masonry engineering, concrete and reinforced concrete engineering, decoration engineering, roofing engineering, etc.

1. subdivisional work: divided according to different construction methods, different materials and different specifications. For example, masonry can be divided into brick masonry and rubble masonry, in which brick masonry can be divided into inner wall, outer wall and parapet according to different parts. Sub-projects are the most basic structural elements for calculating labor, materials and capital consumption.

2. Construction project: refers to a construction unit with legal personality, which is composed of one or several single projects in a general scope, with independent accounting in economy and unified management in administration. For example: a school, a factory.

3. Single project: refers to a project with independent design documents, which can organize the construction independently, and can exert its production capacity or benefit independently after completion, such as the teaching building, experimental building and library of a school.

4. Unit project: refers to the project that can't exert its production capacity or benefit independently after completion, but has independent design and can organize construction independently. For example: civil engineering, electrical lighting, water supply and drainage, etc.

Construction engineering quality acceptance branch

1, unit project refers to buildings and structures that have independent construction conditions and can form independent use functions.

2. Sub-unit project refers to the unit project with large construction scale, and the part that can form independent use function can be regarded as a sub-unit project.

3, division of engineering refers to-according to the professional nature, building parts.

4. Partial projects refer to-when some projects are large or complex, they can be divided into several partial projects according to material types, construction characteristics, construction procedures, professional systems and categories.

5, subdivisional work refers to-according to the main type of work, materials, construction technology, equipment category, etc.

6. Inspection lot refers to the division of floors, construction sections and deformation joints according to the requirements of construction, quality control and professional acceptance.
