This study investigates the impact of Strategic Sustainable Procurement (SSP) practices on competitive project performance among listed construction firms in Abuja, Nigeria. Drawing on Institutional Theory, the research explores how environmental, social and economic dimensions influence project outcomes such as cost efficiency, quality delivery, and stakeholder satisfaction. Using a descriptive survey design, data were collected from 343 respondents across Julius Berger Nigeria Plc and Arbico Plc and analysed using SPSS regression techniques. Findings reveal a statistically significant positive relationship between all three SSP components and Timely Completion, with innovation and compliance exerting the strongest influence. Environmental and economic considerations also showed strong correlations with enhanced project outcomes, while social considerations had a moderate but meaningful effect. The study underscores that integrating SSP into procurement frameworks enables firms to meet sustainability goals, comply with regulations, and gain strategic advantages in Nigeria’s competitive construction industry. It recommends that construction firms institutionalize SSP practices through policy reform, stakeholder collaboration, and continuous capacity building. This research contributes to bridging the empirical gap on sustainable procurement in developing economies and provides actionable insights for both industry practitioners and policymakers committed to driving sustainable development through responsible construction practices.
