Engineering construction is an economic activity that achieves the reproduction of fixed assets. Composed of two parts: civil construction and industrial engineering:
1. Civil construction engineering
(1) Various types of building construction projects, including water supply, heating, power supply, sanitation, ventilation, gas and other equipment and their installation projects included in building construction projects, as well as various pipeline, power, telecommunications and cable laying projects included in building projects.
(2) Equipment foundation, pillars, workbenches, chimneys, water towers, pools and other ancillary works.
(3) Site leveling, engineering and hydrological surveys for construction, demolition of existing buildings and obstacles, temporary water, electricity, gas, roads for construction, and site cleaning, environmental greening, beautification, etc. after completion.
(4) Mining excavation, tunnel extension, oil and gas drilling, as well as the construction of railways, highways, bridges, reservoirs, dams, irrigation canals, and flood control projects.
2. Industrial Engineering
(1) The assembly of various mechanical equipment required for production, power, lifting, transportation, transmission, medical treatment, and experimentation, as well as the installation of workbenches, ladders, railings, and other equipment connected to the equipment, the laying of pipelines attached to the installed equipment, and the insulation, anti-corrosion, insulation, painting, and other work of the installed equipment.
(2) The debugging work carried out to determine the quality of installation engineering, including single machine trial operation of individual equipment and system linkage no-load trial operation of system equipment.
