Analysis of rework risk triggers in the Nigerian construction industry

Abstract

The construction industry plays a significant role in the infrastructure development of many countries. Construction projects suffer from a lot of setbacks despite sophistication and advancement in technology and professionalism. This study, therefore, assessed the factors that triggered the emergence of rework and the benefits derived from eliminating such triggers in the Nigerian construction industry. The study adopted a quantitative survey approach in which a structured questionnaire was adopted as the research instrument. Factor analysis using principal component analysis was adopted to determine the factors that triggered the rework and the pattern of relationship that existed amongst the factors; relative importance index (RII) was used to assess the benefits of eliminating rework triggers. The study concluded that the factors that triggered the emergence of rework were omission and planning issues, change issues, funding and communication issues, and poor workers and resource control. Repeat patronage, higher productivity, and reduced delivery time reduced the rework and waste and improved the employee job satisfaction and morale; they were the benefits derived from eliminating rework triggers. It was recommended that there is a need for clarity, effectiveness, and timeliness of instruction and information dissemination amongst project participants and the participation of contractors, subcontractors, and other stakeholders at the design stages to avoid omissions and construction changes.
