چکیده

زیرساخت‌های عمرانی بنیان اصلی رشد و توسعه اجتماعی، محیط زیستی و اقتصادی جوامع هستند که امروزه در نتیجه‌ افزایش جمعیت و تغییرات اقلیمی با چالش‏های فراوانی مانند بهره‌مندی بهینه از منابع طبیعی مواجه شده‌اند. از این‌رو، استانداردها و روش‏های گذشته پاسخگوی نیازهای آینده نخواهد بود و پایداری پروژه‏‌های زیرساختی یک مسأله اساسی برای جوامع درحال توسعه محسوب می‌شود که ایران نیز از این شرایط مستثنی نیست. پژوهش حاضر براساس نیاز به افزایش طول عمر و ارتقای عملکرد زیرساخت‌ها، با هدف معرفی ابزار مناسب ارزیابی پایداری، به بازنگری و بومی‌سازی سیستم رتبه‌بندی پایداری زیرساخت‌ها (Envision) مطابق شرایط ایران پرداخته است. پس از بررسی ساختار چارچوب Envision مطابق نظرات کارشناسان، ضرورت معیارها در آن با طیف لیکرت ارزیابی شد و در نهایت سطوح مختلف با تکنیک مقایسه زوجی وزن‌دهی و اولویت‌بندی شدند. ضمن اضافه شدن پنج معیار به چارچوب بومی‌سازی شده، درصد وزن‏های به‌دست آمده برای گروه‌های اصلی شامل کیفیت‌زندگی (29.19)، محیط‌‌طبیعی (22.89)، تخصیص‌منابع (17.48)، اقلیم و تاب‌آوری (15.41) و مدیریت‌پروژه (15.02) لزوم توجه بیشتر به بعد اجتماعی را در ایران نسبت به کشور توسعه‌دهنده چارچوب مبنا نشان می‌دهد. چارچوب بومی‌سازی شده دارای پنج گروه اصلی، 14 زیر‌گروه و 69 معیار است که امتیازهایی متفاوت از چارچوب مبنا دارند. نتایج این پژوهش و چارچوب بومی‌سازی ‌شده ضمن ارائه راهکاری مناسب برای توسعه و ارتقای عملکرد پایدار زیرساخت‌ها، می تواند در بهبود فرآیندهای تصمیم‌سازی نیز مؤثر باشد. بنابراین ضمن لزوم بررسی ابعاد مختلف پیاده‌سازی آن در پروژه‌های زیرساختی در پژوهش‌‏های آتی، استفاده از آن برای سیاست‌گذاران، برنامه‌ریزان و سایر ذی‌نفعان پیشنهاد می شود.

چکیده [English]

Civil infrastructures as the foundation of social, environmental, and economic development are facing many challenges, such as the optimal use of natural resources as a result of population growth and climate change. Therefore, previous standards and methods of development are not capable of meeting future needs and the sustainability of infrastructure projects has become a fundamental issue for developing countries like Iran. To address the need of enhancing the infrastructure's performance, this research aimed at introducing an appropriate tool for sustainability assessment by customizing an infrastructure sustainability rating system (Envision) according to Iran's conditions. Accordingly, the credits’ list was firstly investigated through in-depth interviews with experts. Then, the validity for each credit’s existence was assessed through the Likert spectrum. Finally, the weights were revised based on the context-specific circumstances using the paired comparison technique. Alongside the five newly added credits, the research’s findings regarding the main groups’ weights including the Quality of Life, Natural Environment, Resource Allocation, Climate and Resilience, and Leadership highlight the significance of paying more attention to the social aspect of sustainability. The results were structured in a framework consisting of five main groups, 14 subgroups, and 69 credits with new points. The results of this research can be useful in not only the infrastructure’s performance improvement but also enhancing the decision-making process for infrastructure development. Accordingly, investigating the implementation of the proposed framework in Iran’s infrastructure projects, and its application by policymakers and planners is highly recommended for future studies.
