[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] During construction, the problem of stacking building materials such as timber, steel pipes, formwork, and pipes is often encountered. The traditional practice is to stack the building materials directly on the supporting surface. The height of the building materials from the ground is usually fixed and they are usually very close to the ground.
