تطوير نظام دعم القرار لإدارة مخلفات التشييد باستخدام التحليل الهرمي(AHP) لتحقيق معايير الاستدامة في مشاريع التشييد السورية

Abstract

Construction waste management-CWM is an essential component of sustainable construction projects because it helps to minimize environmental impacts, conserve resources, and reduce waste disposal. The development of effective contractual requirements is also essential to ensure that appropriate CWM practices are implemented on construction sites.

 This study aims to propose contractual requirements for construction waste management-CWM within construction contracts, in addition to developing a decision support system for CWM to achieve sustainability standards in construction projects in Syria.

To achieve this goal, a survey was conducted that included 51 engineers and contractors working in the local construction industry to determine the most important requirements that construction contracts must include regarding construction waste management, in addition, interviews were conducted with 18 experts in the construction industry to reach the selection of the optimal alternative to start applying CWM steps in construction projects in Syria. The results of the interviews were analyzed using hierarchical analysis (AHP) to reach the optimal alternative.

The most important requirements to be included in the construction contracts of the projects were as follows:  Pre-determination of the expected waste at the design stage with a preference of 35%, while monitoring and quality standards got 27% and 18% for site management requirements. The research also found that the application of the alternative “participatory work” between governmental and private entities is the best option in the field of applying CWM steps with a preference value of 0.460, but the economic criterion was the most influential on the goal with a value of 0.483.

 This study is considered an entry point to develop construction contracts in Syria to achieve the upgrading of the local construction sector and achieve sustainability standards through the preservation of resources
