    C-DREEM: A framework for estimating the cost of earthquake-damaged buildings – A New Zealand study
    (2025-09-01) Kahandawa Appuhamillage R; Domingo N; Chawynski G; Uma SR
    Natural hazards created by earthquakes require an accurate post-earthquake cost estimation mechanism on the road to recovery. However, there are no identifiable accurate post-earthquake cost estimation mechanisms. This has led to major deviations between the initial and final construction costs. For example, the estimated cost of repair of the 2010–2011 Canterbury earthquake sequence changed from 41 billion NZD to $53 billion NZD (adjusted for inflation). Previous research identified eleven factors that specifically impact post-earthquake cost estimation. The recognisable literature was unable to identify a post-earthquake cost estimation model that considers these factors. Therefore, this research aims to fill this gap by developing and validating the cost of damage repair (including refurbishment) and the Earthquake Estimation Model (C-DREEM) framework. The C-DREEM framework was developed based on previous literature and inputs from a development team that included eleven industry professionals. The developed framework was then verified through a focus group interview consisting of nine professionals. The research developed and verified a framework for cost estimation for earthquake damage repair work, C-DREEM, that impacts earthquake damage repair work. C-DREEM incorporates the factors affecting post-earthquake cost estimation and improves the speed and accuracy of post-earthquake cost estimations for damage repair work.

    Contracting challenges in post-disaster reconstruction in developing countries: Evidence from Nepal reconstruction
    (Elsevier Ltd, 2025-04-15) Puri A; Ameer Ali N; Elkharboutly M
    This study aims to identify the challenges of procuring and contracting post-disaster reconstruction projects in developing countries using conventional construction contracts, with Nepal as a case study. After the 7.6 Mw Gorkha Earthquake in 2015, Nepal embarked on extensive reconstruction efforts supported by various foreign governments and agencies. While these efforts were generally hailed as successful, large-scale non-residential reconstruction projects encountered significant challenges. This issue is common globally due to the lack of attention from researchers on large-scale non-residential reconstruction, leading to overlooked issues and the continuous failure of these projects to meet their objectives. One key issue in such projects is using conventional construction contracts not designed for post-disaster scenarios. This study used a qualitative research design that included semi-structured interviews to collect data and thematic analysis to gain insights from individuals involved in Nepal's reconstruction. Fifteen interviews with experts involved in managing construction contracts during the reconstruction were conducted and analysed using Nvivo 14 software. Upon analysis, two main themes emerged: procurement and bureaucratic, and contract-related, each further divided into sub-categories. These themes highlight how Procurement Act and conventional contracts used in reconstruction in Nepal failed to address post-disaster needs. The findings emphasise the necessity for pre-disaster evaluations and updates to procurement laws and contracts to establish more suitable approaches for reconstruction. Aligning contracts with the specific requirements of post-disaster contexts can significantly enhance the efficiency and effectiveness of reconstruction efforts. Future research should focus on developing disaster-focused contracts to enhance global reconstruction practices.
