Beijing Peony Garden Apartment Building 2 is an assembled frame structure built in 1974. The surrounding environment is complicated, the structure safety and noise and dust control during demolition are the primary issues to be considered. Most components are removed using a nondestructive cutting technique. Described in detail the construction and deployment, retaining the framework of support, component cutting and deformation observation program. Cutting construction did not cause obvious damage to the original structure and deformation, non-destructive structural reform to meet the requirements of demolition.
