Özet:

The construction industry plays a pivotal role in achieving the Sustainable Devel-opment Goals (SDGs), but the effectiveness of different Project Delivery Systems (PDS) in promoting sustainability remains underexplored. This thesis evaluates the alignment of four major PDS—Design-Bid-Build (DBB), Design-Build (DB), Construction Manager-at-Risk (CMR), and Integrated Project Delivery (IPD)—with the SDGs using a Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) framework enhanced by Analytic Hierarchy Process (AHP) weighting. The study's aim was to identify which PDS best facilitates the integra-tion of sustainability into construction projects, thus contributing to the SDGs. Results from the TOPSIS analysis revealed that IPD ranked highest in terms of SDG alignment, followed by CMR, DB, and DBB. The superior performance of IPD is attributed to its highly collaborative nature, which integrates stakeholders throughout the project lifecycle, fostering innovative and sustainable practices. In contrast, DBB's segmented and traditional approach limited its effectiveness in ad-dressing sustainability criteria. The study provides a quantitative method for as-sessing PDS against sustainability criteria, offering valuable insights for industry stakeholders and policymakers. This research contributes to the field by providing a systematic approach to evaluate the sustainability potential of PDS and suggests that adopting integrated project de-livery methods can significantly enhance the construction industry's impact on sus-tainable development. Future research should focus on refining the evaluation crite-ria and applying this framework to specific types of projects to tailor recommenda-tions for practice and policy adjustments.
