Aydın, D and Mıhlayanlar, E (2024) Determination of the significance of project delivery attributes (PDAs) on sustainable projects in Turkey. Journal of Engineering, Design and Technology, 22(5), pp. 1682-1703. ISSN 1726-0531
Abstract
Purpose: Many parameters influence the success of sustainable projects (SPs) in the architecture-engineering-construction. One of these important parameters is the project delivery attributes (PDA), which are influenced by the project delivery system (PDS) while affecting the selection of it. This study aims to evaluate the significance of PDAs in influencing both the performance and success of SPs in Turkey, where the interest in SPs is high. Design/methodology/approach: The impact of PDAs was determined by applying the two-round Delphi method with a semistructured interview involving the main stakeholders of a construction project, like owners, designers, contractors and consultants who played active roles in SPs, as well as academics to theoretically evaluate the issue. The significance of PDAs was assessed using the relative importance index, and the results were validated using the interrater agreement analysis. Findings: The study identified key PDAs impacting SPs as owner character, commitment and motivation; simulation and energy modelling; and timing of stakeholders/early involvement. Originality/value: The investigation of the significance of the PDAs is a lesser-studied context. Therefore, a research framework that enables an effective set of methods for solving the sectoral problems of PDAs that have impacts on SPs has been proposed. The framework is expected to open new opportunities for the generation and regulation of the PDSs for SPs. The findings will provide valuable insights to project stakeholders, particularly owners, local authorities and policymakers to assess which PDAs have a greater impact on sustainability performance when setting PDSs in SPs in other developing countries.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
