Considerable amounts of work have been carried out in developing cost models for the repair and maintenance of earthquake damaged buildings in recent years. Most of these developments have been based on methods and approaches using risk analysis, probabilistic earthquake and scenario earthquakes. The main objectives of this paper can be summarised as: to highlight the extent and variability of influencing factors (quantitative and qualitative) affecting the repair and maintenance of post‐earthquake damage to buildings and structures; and to present the first configuration of a proposed quantitative model for the repair and maintenance of damage inflicted on buildings.


To achieve this, an in‐depth review of the available literature in this field was deemed necessary. The presented literature review, demonstrates the need and the gap in knowledge, as well as the complexity of the subject for such development. In developing the proposed model, attention has been paid to the recommendations made and good practice observed within the industry and the corresponding literature. The suggested assessment mechanism of buildings (data collection) has been proposed in conjunction with the ATC – 38 post‐earthquake building assessment forms and the ASCE/FEMA 356 – pre‐standard and commentary for the seismic rehabilitation of building. The ability (mechanism) to estimate the cost of required repair and maintenance based on a thorough condition survey of the inflicted damage on buildings was of paramount importance in this study.


The main finding reported in this paper, apart from the presented cost estimation methodology and the first configuration of a quantitative model, is the necessity to acquire and establish a broad knowledge base of variables and parameters, influencing such development.


This paper certainly paves the way for a more rigorous and comprehensive approach for further development in this field.
