The study aims to develop standardized BIM methods for buildings that are part of the Moscow city renovation program. This problem is extremely urgent, since there are no digitized sources of typical projects of the last century, and this complicates the process of calculating the generation of construction and demolition waste and casts doubt on its accuracy. At the stage of high quality and timely dismantling phase (calculation of the weight of construction and demolition waste, scheduling of work and transportation of waste), this process can be automated using information modeling software – Autodesk Revit 2019. This will complement the existing information model by including in it one of the final stages of the building’s life cycle – dismantling, which in transparency, accessibility and completeness will not be inferior to the blocks of design, examination, construction and operation. On the basis of albums of typical building projects, you can get a lot of information to create the necessary project families and specifications, which will greatly simplify and speed up the process of developing building demolition projects in the future, since with each new project libraries of elements, materials, families will be supplemented. The article presents the process of developing a project template for the phase of the dismantling of buildings. A new project parameter has been created, assigned to each material of the project template, the necessary parametric and design characteristics have been assigned for further calculations based on the simulated building design, a design specification has been developed, on the basis of which data on the weight of construction and demolition waste can be quickly obtained, relevant checks carried out for different types of developed and basic project families.
