designing an hse management of change model: a case study of civil engineering projects based on the delphi method

Background: organizational environments are constantly changing; hence organizations must adapt to such changes. therefore, this study aimed to design an hse management change model for civil engineering projects.method: this cross-sectional study was conducted in 2019 based on the delphi method. the participants were 39 hse experts working on iran’s large civil engineering project. the instrument of the study was a questionnaire consisting of 40 necessary measures based on the penfold’s change model. the delphi method employed in this study comprised three rounds and was carried out based on the 5-stage penfold’s change model (current situation, analysis, understanding, planning, execution, and keeping changes).results: the results of the delphi study showed that from 60 items after the three rounds, 57 proposals were approved by the specialists. also, 10 out of 15 recommendations were taken by experts in the change management model.conclusion: the final change management model in this study included 38 items for the five stages of change management (based on the integration of 67 items). results indicated that this model can be used to reduce the consequences of changes affecting occupational safety, health, and the environment.
