ABSTRACT
The building industry contributes immensely to the development of any nation even though its contribution is less than the manufacturing industries; it is a major player in the socio-economic development of many countries globally. However, recently, issues of quality, costs, reliability and human and environmental safety have emerged posing a challenge to the growth of the industry. This is as a result of poor implementation phase principles in the industry. Yet, poor implementation in the Nigerian Building Industry (NBI) was linked to its inability to deliver service effectively and efficiently; and these are obstacles on the Nigerian economy. This study therefore sought to determine how implementation phase principles may influence project performance within the building industry in Abuja, Nigeria. Explanatory and descriptive approaches were used to obtain data from completed project files (three from both public and private sectors respectively) and professionals from the building industry. Stratified and purposive random samplings were used to select completed projects and qualitative data for the purpose of analysis. The results revealed that implementation phase principles were not adopted due to poor management of projects, unnecessary rush in project implementation, inadequate planning and budgetary provisions, costly project execution. Still, the current traditional system is not working, but if implementation phase principle is employed, it could improve project performance and will reduce cost and time overruns.
