In spite of the many studies on the role of stakeholders’ engagement in roads construction projects in Zambia, little is known about their impact on performance. One pertinent issue was to address the challenge of ineffective stakeholders’ engagement in roads construction projects by way of considering stakeholders needs and expectations prior to commencement of project implementation. This study was undertaken with the aim to evaluate the impact of stakeholders’ engagement on performance of roads construction projects in Lusaka District under the L400 roads project. The study’s aim was achieved through assessment of relationships between stakeholders’ engagement and the three performance parameters namely; project cost, project schedule and project specifications. The research design that was adopted was a quantitative with descriptive research design. Both primary and secondary data were collected using a semi structured questionnaire which gave a 98% response rate. Findings revealed presence of a strong and positive correlation between stakeholders’ engagement and project schedule also between stakeholder engagement and project specifications. Results also showed that stakeholder’s engagement was strongly but negatively correlated to project cost. It was recommended that a model be developed and adopted for implementing stakeholders’ engagement in road construction projects with room for future development.
