Application of Sustainability on Construction Projects in Sudan "Case Study on Khartoum?s Construction Sector"

The construction industry plays a vital role in economic development but is simultaneously one of the leading contributors to environmental degradation due to high consumption of resources and poor waste management. This study explores sustainability implementation in Sudan?s construction sector, using Khartoum as a focal case. A structured questionnaire was distributed among contractors and consultants, generating 115 valid responses. Statistical analysis using SPSS (Cronbach's alpha = 0.79) confirmed the reliability of the data. Findings indicate that while over 70% of respondents demonstrate strong awareness of sustainable construction benefits, actual adoption remains limited. Resource reduction (38.2%) was the most widely implemented practice, while advanced measures such as on-site recycling (2.4%) and the use of recycled materials (0.8%) were rarely applied. Key barriers include limited policies, weak institutional frameworks, unstable construction costs, and lack of professional training. This study highlights the urgent need for regulatory reform, targeted training, and industry engagement to bridge the gap between awareness and practice. The results provide policymakers and industry stakeholders in developing countries with insights into advancing sustainable construction practices.
