Abstract: In order to studly the demolition methods of high-rise residential buildings in the urban center,this article combines themechanical demolition poject of a high-rise unified office buildting in the urban center, uses BlM technology to study the demolitionprocess and key construction technologies, analyzes the lifing of mechanical equipment required for the demolition of high-rise residentialbuildings, as well as the walking route of mechanical equipment during the demolition operation on the working face, and proposes safetycontrol measures during the demolition process. The results indlicate that high-rise buildings in the urban center should be demolished usingtop-down machinery, strictly following the requirements of green construction demolition. While ensuring demolition safety, the impact ofnoise,，dust，high -altitude objects，and garbage removal during the demolition process on the surroundling environment is effetivelycontrolled. The reeycling and reuse of revycled resources such as steel, crushed stone concrete, pipelines, and equipment costs a total of972000 yuan. This provides a reference for the demolition of high-rise residential buildings in similar urban areas.
