01. Confirm the structure before demolition to avoid the risk of house collapse
When the demolition project is carried out, the first and most important thing is to confirm whether it is safe, especially when the partition is demolished, it may affect the structure of the building, especially the first floor compartment demolition is the most risky, generally speaking, the appearance of the wall, fire protection facilities, the location of the pipeline (water and electricity pipeline) and the shear wall, load-bearing wall, etc. are not allowed to be changed and demolished, if it must be demolished, you must ask a professional structural technician to confirm whether it can be dismantled.
02. There is no dispute between the two parties in the construction according to the drawings
When the design drawing is determined, there will be a demolition drawing, and when the demolition project is carried out, it must be done according to the drawing, so as not to cause controversy without evidence, and if there is a part that needs to be demolished on the non-drawing that needs to be demolished, it must be agreed by both parties and recorded in black and white.
03. Do enough protection work to save money in the future
In addition to public measures and inside and outside the house, before starting to start demolition in order, it is also necessary to do a good job of waterproofing to avoid blocking and penetration, such as the drainage holes of kitchens and bathrooms, balconies, and toilet fecal pipes, all of which must be checked one by one to ensure that the dust and debris in the house block the pipeline. In addition, before the demolition, it is also necessary to confirm the water and electricity cut-off with the administrator, and pull the temporary water and electricity supply on the site to meet the needs of the demolition.
04. Take photos beforehand to avoid disputes
Before starting the demolition project, it is best to take photos and record all the public areas from near to far, especially the elevator doors, gates, and walls and floors of special materials should be photographed as carefully as possible, so as to avoid any doubts by the management committee after completion.
05. Remove the ceiling floor and pay attention to pipelines and water leakage
When demolishing, most of them start from the ceiling, and then go to the wall and the ground, and pay special attention to the pipelines when removing the ceiling, the hidden pipelines such as central air conditioning, fire sprinkler pipes, etc. may be the pipelines of other residents, and when dismantling to the ground, it is necessary to do waterproof engineering in advance to avoid water seepage to the downstairs house during construction. In the case of not affecting cleaning, water supply and drainage, it is recommended to leave the toilet for removal at the end to facilitate the use of staff on site.
