Project Managers’ Performance on Sustainable Construction of Residential Estates Developments in Abuja, Nigeria

Abstract

Encouraged by the support given to the sustainability agenda globally by the United Nations, Nigeria along with many other countries is slowly focusing on achieving a sustainable built environment. This paper assessed the performance of project managers on sustainable construction of residential estates in Abuja, Nigeria by examining project managers’ perception of their own competence, and the performance of project managers on the sustainable construction of residential estates. Data was collected from 26 Project Managers using close-ended-design questionnaires and analyzed through descriptive statistical methods (Mean Score and Relative Importance Index). Historical project data was also obtained on 22 residential estate projects, and was analysed using Percentage analysis. Findings from data analysis revealed that Project Managers are rated high in ten competencies and moderate in six competencies namely Budgeting, Risk management, and Emotional intelligence. The competencies of Project Managers had the strongest influence on project quality performance. All three of the traditional ‘iron triangle’ of project performance indices (cost; quality; time) were highly influenced by technical competencies such as Budgeting and Procurement management. it was recommended that Project Managers participate in Continuing Professional Development (CPD) in order to hone their competencies in areas such as budgeting, risk management, and emotional intelligence where some weakness has been identified in this study.
