Do All Prefabricated Structure Houses Need to Be Demolished?
Not all prefabricated structure houses need to be demolished; instead, differentiated handling strategies are adopted based on the actual conditions of the houses.
For prefabricated panel houses with good structural safety but relatively outdated functional facilities, they are usually not directly demolished. Although these houses were built earlier and may have issues such as aging facilities, their main structures can still meet the requirements for safe use. In such cases, reinforcement and renovation, as well as functional upgrades, are mainly carried out to extend their service lives. For example, replacing aging water, electricity, and gas pipelines to eliminate safety hazards and ensure the safety of residents' daily lives; repairing roof waterproofing and adding insulation layers to improve the waterproofing and insulation performance of the houses and enhance living comfort; and installing elevators in multi-story prefabricated panel houses when conditions permit to facilitate the travel of residents, especially the elderly and those with mobility issues. Through these renovation measures, the functions of the houses can be improved to continue meeting the living needs of residents.
Demolition and reconstruction are only considered when the structures of prefabricated panel houses have serious safety hazards and cannot meet safety requirements through reinforcement and repair. Specifically, houses that have been identified by professional institutions as meeting the standards for dangerous buildings, especially Class D dangerous buildings, may have foundation subsidence and obvious damage to the main structures, such as wall cracks and beam-column deformations, and their continued use will endanger the lives and property of residents; houses with substandard disaster resistance capabilities that cannot effectively ensure the safety of residents in the face of natural disasters such as earthquakes and floods; houses that conflict with urban infrastructure construction, for example, when the construction of subways, roads, etc., requires the occupation of the land where the prefabricated panel houses are located; and prefabricated panel houses located within the scope of urban core area development and renewal and subject to renovation in accordance with urban planning are included in the scope of demolition and reconstruction.
In conclusion, the handling of prefabricated structure houses should be comprehensively judged based on factors such as their structural safety and functional conditions, and they should not be demolished in a one-size-fits-all manner.
