Classification of engineering and construction
Engineering and construction is a kind of economic activity to realize the reproduction of fixed assets. By civil construction and industrial
engineering two parts:
1. Civil construction
(1) all types of housing construction projects and included in the housing construction projects, water supply, heating, power supply, sanitation, ventilation, gas and other equipment and its installation, as well as included in the construction of all kinds of pipelines, electricity, telecommunications and cable wire laying projects.
(2) Equipment foundations, pillars, benches, chimneys, water towers, pools and other ancillary works.
(3) for the construction of site leveling, engineering and hydrological surveys, the removal of the original buildings and obstacles, as well as the construction of temporary water, electricity, gas, road and after the completion of the site cleanup, environmental greening, landscaping and other work.
(4) mine excavation, shaft extension, oil and gas drilling, and the construction of railroads, highways, bridges, reservoirs, dams, irrigation canals and flood control and other projects.
2. Industrial engineering
(1) production, power, lifting, transportation, transmission and medical, experimental and other kinds of need to be installed in the assembly of machinery and equipment, and equipment connected to the workbench, ladders, railings and other installation works and attached to the installation of equipment, pipe laying works and equipment installed by the insulation, corrosion, heat preservation, painting and other work.
(2) in order to determine the quality of the installation works, individual equipment for single test run and system equipment for system linkage without load test run and commissioning work.
