At present building reconstruction in-process, take place to interfere for avoiding newly-added part and original part, can generally rebuild after all parts except that the frame is whole demolishd with old building inside, this in-process can't use large-scale construction equipment, can only rely on the manpower to demolish a bit, follow-up reconstruction in-process still can't utilize the construction entrance to a cave on the floor to transport the material like newly-built, the material is transported very difficultly, whole reconstruction process time limit for a project is extremely long, the amount of labour is very big, the cost often still is higher than newly-built.

Thus, current building reconstruction is very limited, and the functionality of the building before and after reconstruction cannot be significantly different, preferably without involving a modification of the room layout, which would otherwise be irreparable.

The most typical construction scenarios are two types, one is to reconstruct a general ward into a negative pressure ward, and the other is to reconstruct a temporarily used construction such as Olympic village for other uses. The former is generally carried out rarely due to the difficulty of the former, but a shelter hospital is temporarily built when a negative pressure ward is not enough; the latter situation is different, such as the Olympic village of Olympic Games in 2016, which is in a waste state later, the Olympic village of Olympic Games in Tokyo in 2021, which has a plan of being reconstructed into a shelter hospital (the room layout changes relatively little before and after reconstruction, and the difficulty is low), but is not completed, and more times, the Olympic village directly utilizes a nearby hotel or dormitory without new construction.

The application also relates to the reconstruction of Olympic village, namely Olympic village of the Beijing winter Olympic Committee in 2022. It is located in northern and tricyclic areas, and is distributed with a lot of universities, and is planned to be rebuilt into talent apartments after the winter Olympic meeting is finished.
