What is a Division Subdivision ProjectWhat is a Divisional Project?

The quality acceptance of the branch engineering --- determined according to the professional nature of the construction project and the construction part;

When the sub-division project of the construction project is larger or more complex--- it is divided into a number of quality acceptance according to the type of material, construction characteristics, construction sequence, professional system category, etc.;

The quality acceptance of the sub-project --- divided according to the main types of work, materials, construction technology, equipment categories and so on of the construction project;

There is no such title in the quality acceptance assessment of the sub-project --- construction project;

1. "Unified Standard for Quality Acceptance of Construction Projects" GB50300---2013, the quality acceptance of construction projects should be divided into unit projects, sub-projects, sub-projects and inspection batches.

2. In order to unify and facilitate the correct evaluation of the quality and acceptance of construction projects, 1) the inspection batch is the smallest unit of project acceptance, and is the basis for the quality acceptance of sub-projects, sub-projects and unit projects.

2) The acceptance of the sub-project is carried out on the basis of the inspection batch.

3) The acceptance of the sub-project is carried out on the basis of the acceptance of each sub-project included.

4) The quality acceptance of the unit project, also known as the quality completion acceptance, is the last acceptance before the construction project is put into use; One of the conditions for passing the acceptance is that the sub-projects constituting the unit project should be accepted.

3. The specific division of construction engineering sub-projects and sub-projects can be found in the "Unified Standard for Quality Acceptance of Construction Engineering" GB50300---2013, Appendix B.

A project can be divided into civil engineering, equipment, electrical and other projects. It may also be that a project contains many different buildings and structures, and it needs to be subdivided. (sub-project).

Civil engineering can be divided into foundation, foundation, main body and other parts according to the construction order. (Divisional Engineering).

The concept of a subdivision is not easy to express, as illustrated by the following examples:

A unit project refers to: installation, civil engineering, etc.

A sub-project refers to: electrical, water supply and drainage in installation, foundation and main body in civil engineering.

A sub-project refers to: electrical pipe installation, water supply pipe installation, etc., formwork and steel bar installation in civil engineering.

One minute to understand the division standards of rail transit unit engineering, sub-engineering and sub-engineering.

Partial projects refer to projects that cannot independently exert their capabilities or benefits, and do not have independent construction conditions, but have the conditions for settling the project price. Partial engineering is a component of the unit project, usually a unit project, according to the various parts of the engineering entity can be divided into a number of sub-projects, such as housing construction unit engineering, can be divided into earthwork engineering, masonry engineering, concrete and reinforced concrete engineering, roofing engineering, decoration engineering, etc.

Sub-project refers to the subdivision of sub-project, is the basic project that constitutes sub-project, also known as project sub-item or sub-head, it is a construction project or installation project that can be produced through a relatively simple construction process and can be calculated in an appropriate unit of measurement. Generally, the construction sub-items are divided according to different factors such as the selected construction method, the materials used, and the specifications of structural components.

For example, in masonry engineering, it can be divided into brick foundation, brick wall, brick column, block wall, reinforced brick lintel, etc., and in earthwork engineering, it can be divided into excavation, backfill, surplus soil transportation and other sub-projects. The quantity of the engineering entity measured in the appropriate unit of measurement is the engineering quantity, and the unit price of the sub-project with unsynchronized distance is the most basic unit of valuation of the project cost (i.e., the unit price).

Divisional engineering: Divisional engineering is the various components of construction engineering and installation engineering, which are divided according to the main parts of construction projects or types of work projects and installation works. Such as earthwork, foundation and foundation engineering, masonry engineering, ground engineering, decoration engineering, pipeline engineering, ventilation engineering, general equipment installation engineering, container engineering, automation instrument installation engineering, industrial furnace masonry engineering, etc.

Sub-project: Sub-project refers to the component of the sub-project, which is the most basic unit of calculation in the construction drawing budget. It is further divided into sub-projects according to different construction methods, different specifications of different materials, etc.

For example, the reinforced concrete sub-project can be divided into two sub-projects: pounding and prefabrication; Prefabricated floor slab works can be divided into sub-projects such as slabs, hollow slabs, and grooved slabs; The brick wall division project can be divided into sleeping wall (solid wall), hollow wall, interior wall, exterior wall, one brick thick wall, one and a half thick brick wall and other sub-projects.

1. Whether it has independent construction conditions and whether it can produce benefits.

The sub-project does not have the conditions for independent construction, and the sub-project cannot exert its ability or benefit independently. The unit project has independent construction conditions, but the unit project cannot independently exert its ability or benefits. Sub-projects can be completed independently, and sub-projects can exert their capabilities or benefits independently.

2. Differences in composition.

A sub-project is an integral part of a sub-project, and a sub-project consists of multiple sub-projects. A sub-project is a component of a unit project, and a unit project can be divided into several sub-projects. A unit project is an integral part of a single project, and a single project is generally composed of several unit projects.

The difference between the sub-division project and the sub-project is that the nature is different, the division method is different, and the content involved is different.

First, the nature is different.

1. Sub-division project: The sub-division project is a part of the division.

2. Sub-project: Sub-project refers to the subdivision of sub-project, which is the basic project of sub-project.

Second, the division is different.

1. Hold the Zen subdivision blind rubber part project: when the branch project is larger or more complex, it can be divided into several sub-division projects according to the type of material, construction characteristics, construction procedures, professional systems and categories.

2. Sub-projects: Sub-projects are divided into sub-projects according to the main types of work, materials, construction technology, equipment categories, etc.

Third, the content involved is different.

1. Sub-division project: The sub-division project involves the content of foundation and foundation, main structure, decoration, roofing, water supply, drainage and heating, electrical, intelligent building, ventilation and air conditioning, elevator, etc.

2. Sub-project: The sub-project involves site leveling, manual excavation, backfill, foundation cushion, interior wall masonry, exterior wall plastering, ground leveling, external insulation and energy-saving wall, interior wall white latex paint, exterior wall coating, plastic steel window production and installation, anti-theft door installation, etc.

Sub-division works and sub-projects are two common terms used in construction projects, and there are some differences between them.

A sub-division project is a hierarchical structure divided according to the project engineering, which is a subdivision of the entire project, usually according to the nature, location or construction process of the project. Sub-divisions are generally divided into larger areas, such as civil engineering, electrical engineering, municipal engineering, etc., which represent different types of work or types of projects.

The sub-project is a more detailed division than the sub-division project, and the sub-division project is further refined into the construction tasks or construction units of each type of specific cavity section. A line project is a breakdown of a specific project that is used to describe the engineering task more specifically and clearly. For example, in the civil engineering subdivision, there can be different sub-projects such as concrete structure, steel structure, masonry structure, etc.

Therefore, the sub-project pays more attention to the general division of the whole round project, while the sub-project pays more attention to the subdivision and description of specific tasks. Both concepts play an important role in the planning, organization, and management of construction projects.

The difference between the division and the sub-project is mainly in the way of division and the scope of the tomb.

The division project refers to the division of the project according to the various parts and types of work of the unit project, which is a component of the unit project, the former is divided by the part, and the latter is divided by the source of the work.

Sub-project refers to the basic detail work of the sub-project according to different construction methods and different specifications, and it is an integral part of the sub-project.

Precautions when contracting sub-projects and sub-projects:

Before contracting, it is necessary to bid for the contract, which is also the main component of the contracted project, and the price should be considered to complete the obligations under the contract and the expected project profit.

The relationship between the local people should be coordinated to ensure that the excavation process is not hindered and the construction operation is smooth. If the machinery is not handled properly and the machinery is stopped for two days, the machinery rental fee shall be payable. When signing the contract, it is necessary to read and review the contract text clearly, and the risk analysis of the contract should be carried out in combination with the actual situation of the project, and corresponding countermeasures should be taken.

The sub-project is a component of the sub-project, generally according to different construction methods, different materials or component specifications, the sub-project is decomposed into some simple construction processes, is the most basic unit content in the construction project, that is, the various physical engineering quantities usually referred to.

No advertising - unit project sub-project, you can understand it at a glance.

The subdivision project is construction and rehabilitation.

Part or system of a building is a piece of professional equipment; A number of sub-projects are combined to form a sub-project, a sub-project is combined to form a unit project, a unit project is formed when the unit project is combined, and a single project or several individual projects are combined to form a construction project.

The sub-project is a component part of the unit BAI project, which generally refers to the project divided according to the structural part of the unit project, the type of material, type of work or equipment used in the DAO, and the type and model of the project. For example, general civil engineering can be divided into scaffolding works, earthwork works, pile foundation works, masonry works, concrete and reinforced concrete works, doors, windows and timber structure works, roofing and waterproofing works, anti-corrosion, thermal insulation, thermal insulation, decoration and other sub-works.

The sub-project is an integral part of the sub-project, which generally refers to the decomposition of the sub-project into some simple construction processes according to different construction methods, different materials and component specifications. It is the most basic unit content in the project, that is, the various physical engineering quantities usually referred to, such as earthwork subcontracting projects, which can be divided into manual leveling of the site, manual excavation of earthwork, manual digging of grooves and pits, and other sub-projects.

Hello, the main differences between sub-projects and sub-projects are:1Range size:

The sub-project is usually a division of a larger scope of the project, with a higher level of division, and the sub-project is a more detailed layer-by-layer division with a more specific scope of commitment. The scope of the sub-project is relatively large, and the scope of the sub-project is relatively small. 2.

Responsible subject: The sub-project is responsible for the higher-level department, and the sub-project is usually responsible for the middle and low-level organizational units or individuals. The responsibility of the sub-project mainly falls at the department level, and the responsibility of the sub-project mainly falls at the team level.

3.Management mode: The sub-project adopts a broader management method at a higher level, and the sub-project adopts a more detailed management and control mode, which requires more accurate calculation and control of the construction period, cost, quality, etc.

4.Synthesis method: The results of the sub-project are synthesized through the division of labor of various departments, and the results of the sub-project are summarized and integrated through the division of responsibilities.

Therefore, the sub-project is more dependent on the cooperation of various departments, and the sub-project is more dependent on the connection between the various responsibility systems. In general, the sub-project has a wider scope, a higher level, and requires a wider range of management, while the sub-project has a more specific scope, a lower level, and requires more detailed management and control. The two are different stages of the layer-by-layer division project, and corresponding management methods need to be adopted.

Hope it helps.
