Based on the growing ethos that construction organisations can benefit from implementingsustainable practices, this study evaluated main contractors’ project delivery practices forsustainability. The objectives were to validate set of empirically weighted criteria for constructionorganisations’ sustainability practice assessment. The weighted criteria were validated by assessingthree main contractors’ organisations’ sustainability performance in four projects. The sustainabilityperformance was evaluated based on sound environmental management principles, robuststakeholder engagement and responsible project management. Data were collected usingquestionnaire survey and project auditing. The study targeted 76 stakeholders in contractors andengineering consultancy organisations in Akwa Ibom State, Nigeria. Criterion suitability was based onrespondents’ agreement score in inter-rater agreement (IRA) scale. Correlational effects wereexplored in published and assessed weightings using Multiple Analysis of Variance (MANOVA). Thefinding indicated contractors’ inclination towards sustainable construction practice must bestrengthened. MANOVA correlation showed published and assessed weightings differ significantlywith (Lambda (4, 2) = 0.056, p = 0.418). The study submits weighted criteria are suitable forassessing a practice. The criteria are by this means validated and form assessment benchmarks foruse in the absence of standard tool. The region must institute incentive and reward systems tostimulate widespread sustainable practices application within the contracting sector.
