Construction professionals' perspectives on drivers and barriers of sustainable construction

With the associated environmental challenges and unsustainable patterns of construction, there is also notable awareness and willingness among the state bodies to adopt sustainability measures and practices in Kazakhstan. This study explores the drivers of and barriers inhibiting the adoption of sustainability paradigm in the construction context of Kazakhstan. The drivers and barriers were validated through the survey and structured workshop with the construction professionals to ensure their relevance to the local context, which were then ranked according to their levels of influence through the lens of the industry professionals in Kazakhstan. Delphi technique was the last stage before consolidating the specified lists. Stakeholder opinions were then consolidated to develop a context-oriented decision support system. The findings reveal that addressing environmental issues is vital to increase the level of sustainability leading to the more efficient use of construction materials and resources. Various social aspects are also found to be driving forces for the effective adoption of the SC concept. On the other hand, a great portion of SC barriers is related to economic aspects, which are followed by government as well as awareness and education related barriers. The findings are hoped to contribute to the body of knowledge in terms of drivers of, and barriers to SC in developing countries, particularly in Central Asian countries due to similarities in context. The findings may also be useful for the construction forefront players seeking ways to improve sustainability performance of the construction industry
