FRAMEWORK FOR SUSTAINABLE CONSTRUCTION PROJECT PERFORMANCE IN LAGOS AND ABUJA, NIGERIA

Abstract

Sustainable construction aims to meet vital day to day needs for housing, infrastructures and working environment without affecting or compromising on-coming generation ability to meet their own need when it comes. Sustainable construction project (SCP) happens to be developing in Nigeria and it’s advancement into Nigerian Construction industry is at a very slower pace because as at today, there are very few projects readily available in Nigeria that have scaled through a good rating from sustainable measurement tool. This study through interview and administration of questionnaires to professional who participated in sustainable construction projects in Nigeria examined the barriers to achieving SCPs in Nigeria, success factors relevant to achieving SCP, criteria to consider for sustainable construction and finally through the means of a balanced score-card, formulate a framework for measuring the performance of SCP. The interview was designed to have Eleven (11) questions and the questionnaire was designed on a 5-point likert-type scale to have Four (4) sections. Data analysis were done using Mean Item Score, Severity Index, Relative Importance Index and Balanced Scorecard. The result shows that major barriers in achieving sustainable construction project in Nigeria are client’s unawareness, overall management action, lack of fund and contractual procedures. Also, success factors towards achieving sustainable construction project is majorly developing an assessment system suitable for Nigeria system and improving professional’s consciousness. Several criteria that makes habitable construction project among others are Safety and Incident risks, acoustic comfort and visual comfort. Finally the scorecard show that sustainability performance measurement is a crucial task at every stages of construction. The study recommended that framework in this research among others can be looked into and amended to fit the purpose of Green Building Council of Nigeria (GBCN). Also, organizations are recommended to utilize the integrated methodology presented in this research with their current performance measurement systems. However, further studies could create efficient reporting system and a software support tools for the framework developed in this study in order to provide an automated mechanism to assist in the measurement of project performance and further provide management and user with necessary information for decision-making.
