How many meters of an industrial building wall can be destroyed with area of 14400 meter square and height of 15 meter by a Bulldozers in a day?(wall is located in envelope of building)

Hello Amir, 
First of all, a bulldozer is not used to demolish a wall or any type of structure. It is used to level soil, subgrade, or pavement material.
As the wall height is 15m and is located in an envelope of the building, the demolition process becomes slow. A stage-wise demolition is to be planned where the top 1m of the wall is demolished first and so on. 
Many factors such as the movement of the machine, removal of debris, skilled operator, and other surrounding factors govern the quantity of demolition that can take place in a day.
