Identification and evaluation of health, safety and environment (HSE) parameters affecting urban construction projects with emphasis on sustainable development

Various studies have shown that paying attention to HSE principles in urban constructions can contribute to sustainable urban development. This study is designed to provide a model for environmental protection in urban construction projects.

This cross-sectional study was performed in 2021. In the first step, a comprehensive study was conducted with the aim of compiling a preliminary list of indicators of sustainable urban development. Then the factors affecting the management of the urban environment were studied and in the next step, the initial conceptual model was formed. In the final step, the validity and reliability of the model were determined through Delphi technique and factor analysis method. The adequacy of the measurement model in structural equation modeling was examined. Data analysis was performed using SPSS and Smart PLS software.

The results showed the reliability of structural factors (7-question), content factors (7-question) and barriers and injuries (13-question) respectively 0.716, 0.821 and 0.831 and the amount of factor loading for all measures were estimated above 0.4. The goodness-of-fit indices of this model including χ2/df, RMSEA, GFI, AGFI, CFI and NNFI were estimated at 2.25, 0.061, 0.96, 0.91, 0.98 and 0.97, respectively.

The findings indicated that considering each of the 27 indicators in urban HSE management can be an effective step towards protecting the urban environment as much as possible in constructions and urban sustainable development.
