Abstract

The provisioning of a minimum standard level of settlement and the designing of camps are among the primary and essential rights and requirements of those subjected to disasters or conflicts. The presence of shelters is essential to resist diseases and protect against natural and non-natural hazards. It is also important to maintain the dignity of humans in the family and social frameworks in tough situations. The present study involved the emergency tent of the UN high commissioner for refugees (UNHCR), Q-shelter, tarpaulin-concrete shelters, recycled-paper pipes, rock-block buildings, safe units, pre-construction wooden building system, lightweight steel frame (LSF) building system, insulating concrete formwork (ICF) building system, and sliding structure system. This study investigates the possibility of using new construction management methods and technologies in Iran to establish temporary settlement sites after disasters from different perspectives, such as consistency with environmental conditions, passive defense, cost, execution speed, ease of facilities, construction technologies, and execution quality via the hierarchical analysis approach. According to the final scores of new temporary settlement establishment methods, Q-shelters were found to be the most consistent method with environmental conditions. Also, the highest passive defense score was obtained for the LSF building system. Also, the final weights of the decision criteria indicated that the highest effect was derived for execution speed at a coefficient of 0.203. Finally, obtaining a score of 0.156, the LSF building system was found as the best building system in the mass housing project based on the six criteria, followed by the sliding structure building system in the second rank. Moreover, the smallest score was obtained for the rock block system.
