Engineering is the classification of engineering, and professional engineering includes: building construction engineering, smelting engineering, mining engineering, chemical and petroleum engineering, water conservancy and hydropower engineering, power engineering, agriculture and forestry engineering, railway engineering, highway engineering, port and waterway engineering, aerospace engineering, communication engineering, municipal public engineering, and electromechanical installation engineering.

Extended data:

Main functions of the project: 1. Research: apply the concepts, principles and experimental techniques of mathematics and natural science to explore new working principles and methods.

2. Development: solving various problems encountered in the application of research results to practice.

3. Design: Choose different methods and specific materials to determine the design scheme that meets the technical requirements and performance specifications to meet the requirements of the structure or product.

4. Construction: including site preparation, material storage, selection of economic and safe working steps that meet quality requirements, personnel organization and equipment utilization.

5. Production: Considering human and economic factors, choose the factory layout, production equipment, tools, materials, components and technological processes, and test and inspect the products.

How to fill in the subcontracting project category?

The name of the subcontracting project in the qualification of the labor subcontracting unit shall fill in the scope of contract.

What are the types of subcontracting? There are three main types of engineering contracts: 1, infrastructure and civil engineering. Such as water conservancy, dams and canal projects; Highway and railway construction; Underground construction projects (pipelines, test wells and underground passages); Bridges, ports and onshore buildings (docks, trestles, dredged breakwaters); Airport and missile engineering; Water supply and drainage works; * * engineering; Classical architectural engineering imitating history or scenic spots, etc.

Legal basis: There are corresponding provisions in the Building Law of People's Republic of China (PRC): Article 29 The general contractor of a construction project may contract out some contracted projects to subcontractors with corresponding qualifications; Except for subcontracting agreed in the general contract, it must be approved by the construction unit.
