Climate change has become an urgent concern for the construction sector in Iran, especially in environmentally vulnerable areas such as Lake Urmia and Pardis New City. This study explores how climate-related factors are currently addressed in construction project planning, design, and execution. The main objective of this thesis is to examine how climate change affects key aspects of construction project performance, particularly cost, schedule, and safety and how professionals perceive and respond to these challenges based on their awareness and experience.
A quantitative research method was applied, using a structured questionnaire distributed among 77 construction professionals, including engineers, project managers, and site supervisors. Data were analyzed through descriptive statistics, correlation analysis, and Cronbach’s alpha to test internal consistency.
The results show a moderate level of climate risk assessment implementation (mean = 2.27), and a clear recognition of climate-related impacts on project cost and time (mean = 2.85). A statistically significant negative correlation (r = -0.318, p = 0.006) was found between risk assessment practices and cost/time disruptions, indicating that proactive planning reduces adverse outcomes. However, the study found weak links between safety actions and existing building codes, and low confidence in national regulations like Chapter 19 and BEEC.
The study concludes that while awareness of climate risks exists, practical implementation remains limited. For the construction sector to adapt effectively, investments are needed in training, development of standardized tools, and revision of regulatory frameworks to ensure climate resilience in future projects.
