In this paper, a loss estimation evaluation for Christchurch CBD, with focus on reinforced concrete (RC) buildings, is conducted with the main aim to improve the reliability of current procedures to support the aforementioned decision-making process. Comparisons are made between field observation on the damage of RC buildings of different age and structural types, collected in a comprehensive damage-report, and the 

post-dicted results of impact assessment obtained using the generated hazard map and fragility relationships. As the work is in progress and the results herein presented are to be considered at this stage indicative of the general features and potential of the approach undertaken, discussion on possible improvements and suggestions for further investigations are presented as well.
