The demolition is not in place, and it will cost more money later

01. Confirm the structure before dismantling to avoid the risk of house collapse

When demolition is in progress, 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. In particular, the demolition of the first-floor partition is the most risky. Generally speaking, the appearance of the wall, fire protection facilities, the location of the pipeline (water and electricity pipelines), shear walls, load-bearing walls, etc. cannot be changed or demolished. If you must demolish, you must ask a professional structural technician to confirm whether it can be demolished

02. There is no dispute between the two parties during the construction according to the drawings

When the design drawing is finalized, there will be a demolition drawing in it. When the demolition project is carried out, the drawings must be carried out to avoid disputes caused by unfounded claims. If there are parts that need to be dismantled that are not on the drawings, they must be dismantled. It was agreed upon by both parties and recorded in black and white

03. Do enough protection work to save money later

Protection work must be carried out before demolition. In addition to public measures and indoor and outdoor, waterproofing is also required to prevent blockage and penetration before demolition begins. For example, drainage holes in kitchens, bathrooms, balconies, and toilet manure pipes must be checked item by item to see if they are sealed properly to avoid dust and debris blocking the pipelines. In addition, before demolition, it is also necessary to confirm water and power outages with the administrator, and connect temporary water and electricity supplies on site for demolition

04. Take photos beforehand to avoid  disputes

Before starting the demolition project, it is best to take photos and records of all public areas from near to far. Especially the elevator doors, gates, and walls and floors made of special materials should be taken as carefully as possible to avoid any doubts from the management committee after the completion. For the purpose of giving evidence

05. Pay attention to pipelines and water leakage when removing ceilings and floors

When removing, most people start from the ceiling, then move on to the walls and floors. When removing the ceiling, pay special attention to the pipelines. The hidden pipelines such as central air conditioners and fire sprinkler pipes may be pipelines of other residents. When removing the floor, waterproofing works need to be done in advance to prevent water from seeping into the downstairs residence during construction. Without affecting cleaning, water supply and drainage, it is recommended that the toilet be removed last to facilitate on-site use by staff
