City information model for the optimization of urban maintenance cost

Public authorities address issues related to urban maintenance management on a daily basis. Maintenance is vital for preserving efficient architectural and functional quality, but the economic resources that can be invested in it are increasingly limited. Thus, authorities tend to carry out maintenance works only when effective emergency situations occur. On the contrary, adopting a preventive maintenance plan would allow a better management of the available budget and savings of resources. The paper aims to present a methodology to optimize maintenance costs by integrating GIS and BIM systems in order to create a City Information Model (CIM). It is meant to optimize management and monitoring of urban maintenance works assisting public authorities in their effort in making a more efficient use of the economic resources allocated.
