The main features of the construction industry are:
First, the liquidity of production.
In the production process of a product, construction workers and machines and tools should flow up and down and left and right along the construction objects in different construction parts, and constantly change the working place. In order to adapt to the frequent changes of construction conditions, most construction machines and tools are relatively small or easy to move, and there are many manual operations, which affects the development of construction technology to some extent.
Second, the oneness of production.
Because of the different functional requirements, natural conditions and socio-economic conditions of buildings or structures, each project has its own unique engineering design and construction organization design, so the product price must be determined separately and the cost accounting must be carried out separately.
Third, the production cycle is long.
The construction period of large-scale projects is often in years, and construction preparation takes a long time. Therefore, it often takes up a lot of manpower, material resources and funds for a long time in production, and it is impossible to provide useful products in a short time. ④ There are many open-air and aerial operations, which are greatly influenced by natural climatic conditions, and the quality and safety problems are outstanding.
