What is the relationship between a single project and a sub project? 10

A single project includes a sub-project, and a sub-project includes a sub-project, but the division of different projects is also different.

1. A single project includes a number of sub-projects.

2. The sub-project includes a number of sub-projects.

3. The sub-project includes a number of inspection batches.

Construction projects are divided from large to small as follows: construction projects, individual projects, unit projects, sub-projects, and sub-projects.

A single project contains a sub-project, and a sub-project contains a sub-project.

A single project is an integral part of a construction project, which generally refers to a project that has independent design documents and can independently exert production capacity or benefits after completion;

The unit project is an integral part of a single project, which generally refers to the project that has independent organization and construction conditions, that is, it is used as a separate cost calculation object, but cannot be produced or exerted benefits independently after completion.

The sub-project is an integral part of the unit project, which is divided according to the different structural parts, materials, types of work or equipment types of the unit project;

The sub-project is a component of the sub-project, which is generally divided into some simple construction processes according to different construction methods and different materials, that is, the construction specifications, which is the most basic unit content of the construction project, that is, the physical quantity of various projects usually referred to.

Definition of construction project, single project, unit project, sub-project, sub-project 1, construction project refers to a construction unit that is composed of one or several individual projects within an overall scope, implements independent accounting economically, implements unified management administratively, and has the status of a legal person. Example: a school, a factory, etc.

2. A single project refers to a project in which it has independent design documents, can independently organize construction, and can independently exert production capacity or benefits after completion. For example, a school's teaching building, laboratory building, library, etc.

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

4. The sub-project is divided according to the different parts of the project, the type and model of the equipment, and the materials used. Examples: foundation works, masonry works, concrete and reinforced concrete works, decoration works, roofing works, etc.

5. The sub-projects are divided according to different construction methods, different materials and different specifications. For example, masonry works can be divided into two categories: brick masonry and rubble masonry, of which brick masonry can be divided into interior wall, exterior wall and parapet wall according to different parts.

Sub-project is the most basic structural element for calculating the consumption of labor, materials and capital.

A unit project refers to a project that has independent design and independent construction conditions, but cannot independently exert production capacity or benefits, and it is an integral part of a single project. For example, the single project of the production workshop is composed of plant construction engineering and mechanical equipment installation engineering. Construction projects can also be subdivided into general civil engineering, plumbing and sanitation engineering, electrical lighting engineering and industrial pipeline engineering and other unit projects.

Examples of subdivisions:

Divisional engineering, sub-engineering, unit engineering, and individual engineering are terms in construction engineering, and there is a certain hierarchical relationship between them.

1.Segment project: refers to the large-scale project part of the construction project divided according to the content, nature, and area of the project.

The sub-project is usually divided into different parts according to the architectural design requirements and construction management needs, such as the structural sub-project, the water supply and drainage sub-project, the electrical sub-project, etc. Sub-projects can be further refined into sub-projects.

2.Sub-project: refers to the more detailed division of the sub-project according to the characteristics of the project, the part of the project or the construction method.

The sub-projects are further subdivided on the basis of the sub-projects, and are more specific and clear, such as the sub-projects that can be included in the structural sub-projects, such as foundation and foundation engineering, main structure engineering, etc.

3.Unit project: refers to the specific engineering unit divided by the sub-project according to the scale and construction requirements.

The unit project is a more specific and detailed division of the sub-project, which determines the boundary and scope of the construction project, and is usually a relatively independent engineering unit, such as pile foundation engineering, basement engineering, etc. in foundation engineering.

4.Single project: refers to the construction task or construction project with the pure body.

A single project is a more specific division of the unit project, and it is a specific work task that needs to be completed in the actual construction process, such as each pile under the pile foundation project in the foundation project can be regarded as a single project.

To sum up, the sub-project is a large-scale division of the entire construction project, the sub-project is a more specific subdivision of the corresponding sub-project, the unit project is a further division of the sub-project, and the single project is the specific construction task or project of the smallest unit. Pin-accompaniment.

1. The project of the bid section is regarded as a single project;

2. Roadbed, culverts, tunnels, interchange bridges, and bridges are divided into unit projects;

3. The filling and excavation in the roadbed, the pile foundation, piers, etc. in the bridge are sub-projects.
