Title of Article: Millennium Development Goals and the Impact of Registration on the Performance of Construction Subcontractors in Nigeria

Arising from the quest to achieve sustainable built environment and the millennium development goals in developing countries, the study examined the influence of registration on the performance of subcontractors in the Nigerian construction industry. The principal objective was to find if any relationship exists between registration and the performance of subcontractors in the Nigerian construction industry. By focusing on three commercial nerve centres of the country (Lagos, Abuja and Port Harcourt), 90 main contractors were randomly selected from the study population of 880 in the register of the Federal registration Board of Nigeria. 96 subcontractors, 90 clients and 92cconsultants were also randomly selected from the population. Descriptive and inferential (Chi-square probabilities) statistical techniques were used for the analysis. The results showed that the registration had no significant effect on the overall performance of subcontractors on construction sites in Nigeria (χ = 2.07, p = 0.05). The results also indicated that majority of the main contractors (49.4%) give notification to these specialty contractors when they are needed on site. On the other hand, a paltry number of the contractors (33.3%) affirmed that it is left for the subcontractors to monitor the progress of their bidding and final selection on sites. The study concluded that for a meaningful monitoring, sincere attention should be shifted towards registration of subcontractors with the relevant professional bodies and that competitive bidding should be encouraged among the subcontractors.
