A single project refers to a complete set of projects with independent design documents, which can independently exert production capacity or benefit after completion. To put it bluntly, it is a house. . Building engineering can be subdivided into general civil engineering, pipeline engineering, electric lighting engineering and industrial pipeline engineering.
Excuse me, what is a single project, a unit project, a sub-project and a sub-project
1. Single project: also known as engineering project, refers to the project with independent design documents in the construction project, which can independently exert production capacity or engineering benefits after completion. It is an integral part of building projects (such as factories, hospitals and schools), such as office buildings, canteens and student dormitories.
2. Unit project: refers to a project with independent design and construction, which is an integral part of a single project. Such as a dormitory building construction project (such as equipment foundation, bridge, culvert, tunnel, etc. ), equipment and installation works (such as the procurement and installation works of transmission electrical equipment and crane electrical equipment).
3. Division project: it is a part of the unit project, generally divided according to the main structure, parts and types of installation projects of the building. Such as earthwork, concrete engineering and pile foundation engineering. )
4. Sub-project: it can be produced by relatively simple construction technology, and the engineering products can be equipped with construction equipment calculated by appropriate measurement units. It is only a basic component of construction or installation project, a product to determine the cost of construction or installation project, and also a basis for budget.
As mentioned above, a bidding project can be regarded as a single project; Subgrade, culvert, tunnel, overpass bridge and bridge are divided into unit projects; Subgrade filling and excavation, bridge pile foundation and pier are subdivisional works.

What are the projects in the building? What is a unit project? What is a single project?
construction project
Refers to the contract composed of investment and construction by the construction unit with legal person qualification, consisting of one or several single projects, which are independently accounted for economically and managed administratively, and are collectively called construction projects.
2, individual projects
Refers to a project with independent design documents, which can independently organize construction and independently exert production capacity or benefit after completion. For example: the school's teaching building, experimental building, library, etc.
3, the 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.
4, division of engineering
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.
5, subdivisional work
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.
Unified Standard for Quality Acceptance of Construction and Installation Engineering is more detailed:
Quality acceptance of construction projects should be divided into unit (sub-unit) projects, division (sub-division) projects, sub-projects and inspection lots.
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, which can be divided into several sub-division projects in terms of certain material types, construction characteristics, construction procedures, professional systems and categories that can form independent use functions. Work for subordinate units;
3. Item refers to: determined according to the professional nature and building location;
4. Division project refers to: when the division project is large or complex, you can press.
5. The breakdown refers to the classification according to the main types of work, materials, construction technology and equipment categories;
6. Inspection lot refers to the division of floors, construction sections and deformation joints according to the needs of construction, quality control and professional acceptance.
7. Single project refers to the single subcontract given according to the professional nature in the Construction Law and the Bidding Law.
What is the definition and difference between a single project and a unit project?
Single project: also known as engineering project, is the basic unit of construction project. A construction project can be a single project, or it can contain multiple single projects. The so-called single project is a project with independent design documents and independent budget estimates, which can independently exert the production capacity and benefits stipulated in the design after completion. Highway construction projects generally refer to independent bridge projects and tunnel projects, generally including wiring with existing highways, which can independently play the traffic function after completion. The bridge or tunnel in a line can't play a traffic function before the whole line is completed, so it can't be regarded as a single project. Unit project: it is an integral part of a single project, with independent construction drawing design and independent construction conditions, and can be used as the object of cost calculation alone. A single project should generally be composed of several unit projects, or it can be composed of only one unit project. For example, a single tunnel project can be divided into civil engineering, lighting and ventilation engineering and other unit projects; The first-class highway can be divided into line engineering, bridge and culvert engineering and other unit projects. Division project: The components of a unit project are generally divided according to the main structure and main parts of the unit project. In highway construction projects, the determination of sub-projects is based on the engineering parts, engineering structure and construction technology within the scope of the project, and the premise is to facilitate the project settlement and economic accounting in the process of project implementation. For example, it is divided into subgrade engineering, pavement engineering, bridge and culvert engineering according to the engineering position, and earthwork engineering, concrete engineering and masonry engineering according to the engineering structure and construction technology. Sub-project: it is a part of sub-project and is divided according to different structures, materials and construction methods. For example, foundation engineering can be divided into cofferdam, foundation excavation, foundation masonry, backfill and other sub-projects. It is also the basic unit of measurement of budget quota, so it is also called engineering quota subtitle or engineering detail. For example, subgrade earthwork is divided into loose soil, soft soil and other earth-rock components, and foundation masonry is divided into flaky and rubble. In short, it is the basic unit of construction and installation engineering.
What is a single project?
Single project, also known as engineering project, is the basic unit of construction project. A construction project can be a single project, or it can contain multiple single projects. The so-called single project is a project with independent design documents and independent budget estimates, which can independently exert the production capacity and benefits stipulated in the design after completion.
Highway construction projects generally refer to independent bridge projects and tunnel projects, generally including wiring with existing highways, which can independently play the traffic function after completion. The bridge or tunnel in a line can't play a traffic function before the whole line is completed, so it can't be regarded as a single project.
What are the differences and connections between divisional projects, sectional projects, unit projects and single projects?
1, the size relationship in the same project (from big to small):
Single project unit engineering division engineering subdivisional work.
2. A single project is an integral part of a construction project, and it is an independent project with independent design documents, which can independently exert its benefits or production capacity after completion. Such as warehouses and houses.
3, the unit project has no independent production capacity, but independent construction organization design and drawings of the project. Such as: civil engineering and installation engineering.
4. Sub-project: The unit project is divided into sub-projects according to the type or main part of the project. Such as: foundation engineering, main engineering, electrical engineering, ventilation engineering, etc.
5. Sub-projects: According to different construction methods, structures and specifications, sub-projects are divided into sub-projects. Such as the installation of cast iron pipes, steel pipes and valves in earthwork, reinforcement engineering and water supply engineering.
What do you mean by unit project and single project? What is the difference?
A project is divided into: project-single project-unit project.
For example: my current project and Sheng Pharmaceutical Industrial Park. Project-Hesheng Pharmaceutical Industrial Park Project;
Hesheng pharmaceutical industrial park project is divided into the following individual projects: sewage treatment station, production workshop, power distribution project and master plan project. . ;
Sewage treatment station can be divided into water collection tank, sedimentation tank, aerobic tank, secondary sedimentation tank, dosing room and power distribution room. . . . ; The production workshop is divided into comprehensive preparation, pretreatment workshop, machine repair workshop, comprehensive warehouse and comprehensive preparation. . . . ; General grades are divided into field leveling, road, rainwater pipe network and sewage pipe network. . . Equal unit project.
What are the individual items in the measurement project?
Measures refer to projects that occur before and during the project construction to complete the project construction, mainly referring to projects in technology, life and safety.
Including:
architectural engineering
Decoration Engineering
assembling work
municipal engineering
What do construction projects, single projects, unit projects, sub-projects and sub-projects mean?
Construction projects refer to projects to be built,
Single project refers to water and electricity, civil engineering, heating and ventilation, etc. In the project, that is, the so-called single project.
The whole project or unit project,
Sub-projects refer to ten sub-projects such as foundation and foundation engineering, main structure engineering, building energy-saving engineering, building decoration engineering, building roof engineering and building electrical engineering. 10 subproject has subprojects.
A subproject is a more detailed project under a subproject. For example, the concrete structure subproject in the main structure subproject is divided into several subprojects, such as formwork, steel bar, concrete, prestress, cast-in-place structure and assembled structure.
Expenses included in the comprehensive budget of individual projects
What expenses are included in the comprehensive fee in the project budget?
The calculation book includes cover, budget table, total project price table, bill of quantities of single project, quotation table of main materials and equipment of single project, quotation table of fixed direct cost, man-machine material analysis table of single project and charging table of single project in turn.
The cost of main materials and equipment should be accounted for according to the purchase price of the equipment plus a certain profit.
The fixed direct fee shall be recorded according to the local budget quota and related quota adjustment documents.
Man-machine material analysis table refers to the quantity and proportion of man-machine materials in a single project. Labor cost refers to comprehensive man-day unit price × labor consumption, material cost refers to auxiliary material cost, and machinery cost refers to equipment machine-team unit price × consumption, which is calculated according to local budget quota.
The charging items generally include: scaffold use fee, super-high construction fee, temporary facilities fee, site fund, enterprise management fee, profit and tax.
Expenses refer to the expenses stipulated by national laws and regulations such as sewage charges, fixed metering fees, social security fees, unemployment insurance, housing accumulation fund, medical insurance and accidental injury insurance, so they are called expenses. The charging standard shall be implemented in accordance with the relevant provisions of the state or region. ) The total project price is a summary of the prices of each project.
I hope I can solve your problem.
