Damage that occurs to a building must receive serious attention from office building managers. This is due to the potential for damage to the building that can cause safety risks and discomfort. State buildings should have a building life plan of up to 50 years. Therefore, maintenance and care of state buildings are carried out by considering the age of the building, depreciation, and building damage. Building D in the Kutai Kartanegara Regency Government Office Complex, which was built in 2004, is one example where there is some damage in the building caused by the conversion of several rooms, weather changes, and lack of maintenance.
