[0002] Construction refers to production activities during the implementation phase of engineering construction. It is the process of building various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction and decoration engineering construction. Construction belongs to the category of fixed assets, including two major categories: houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods and conduct other social activities. What is different from buildings is structures. Structures refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges and chimneys. In the process of construction, a large number of scaffolds are needed at the construction site to facilitate workers to climb up for construction work.
