Prefabricated House Demolition Process
The prefabricated house demolition process mainly includes five stages: pre-demolition preparation, approval process handling, demolition operations, site cleanup and restoration, and follow-up work.
Pre-demolition preparation: The homeowner needs to bring materials such as an ID card and property ownership certificate to the sub-district office for registration and submit a demolition application; clarify the nature of the house and regional planning requirements; conduct a safety assessment of the house structure and formulate a detailed demolition plan covering the demolition sequence, tools, and personnel assignments; establish a demolition project team and provide professional skills training and safety education to construction personnel; prepare demolition tools, protective equipment, and transport vehicles, set up scaffolding, and prepare large-scale mechanical equipment such as excavators; clean up the construction site and set up fences and warning signs to isolate the construction area.
Approval process handling: The sub-district office organizes personnel to conduct on-site inspections. If the demolition is confirmed to comply with planning requirements, it is reported to the relevant district-level departments for approval; if not, a response with reasons is given. The applicant brings the materials to the district-level planning department for approval. If the house is located within the protection scope of cultural relic protection units or historical buildings, opinions from the cultural relic administrative authorities should be sought and approval procedures should be completed. After the planning department approves the application, documents such as a site selection opinion letter, planning permit, and construction permit are issued. The homeowner must carry out the demolition in accordance with the requirements of these documents and comply with relevant regulations.
Demolition operations: First, cut off the connections between the prefabricated panels and the surrounding structures, such as steel bars and bolts; remove the house's doors and windows; use gas cutters or cutting machines to cut the prefabricated panels of the exterior and interior walls and remove them with crowbars, paying attention to protecting the structural columns and beams; use a cutting machine to cut the floor slabs into small pieces and then remove them manually; remove the stair handrails and treads and then demolish the entire staircase; use a cutting machine to cut the roofing materials into small pieces and then remove them manually.
Site cleanup and restoration: Classify and stack the demolition waste, clean up the construction site to ensure there are no residues; level the demolished site to prepare for subsequent construction.
Follow-up work: After removing the prefabricated panels, inspect the house structure to eliminate safety hazards; if necessary, carry out repair work on the demolished parts, such as filling holes and reinforcing structures; conduct follow-up resettlement or reconstruction work in accordance with planning requirements and relevant policies. If compensation or replacement is involved, handle the relevant procedures in accordance with the prescribed procedures.
