Involvement of Building Professionals and Regulatory Agencies Effectiveness in Delivery of Private Housing Projects in Part of Nigeria

The persistent building failures of private building projects in part of Nigeria, especially Lagos state, highlights the critical need to assess the involvement of building professionals and government regulatory agencies effectiveness in private housing delivery in the study area. Hence, this paper established the mediating role of the level of involvement of professionals and government regulatory agencies on the association between the haphazard construction practice and the delivery of private housing projects in the study area. The study was conducted using the quantitative research design. The obtained data was analysed in terms of Partial Least Squares Structural Modelling (PLS-SEM), as the measure of the impact of the involvement of professionals and the effectiveness of government regulatory agencies in the sphere of delivery of housing privately. The results revealed that there was a diminished inverse and insignificant indirect effect of involvement of building professionals (IPB) on the relationship between haphazard construction practices (HCP) and delivery of private housing projects, IBPs x HCP -> DLV_HP:(β = -0.102, P-Value = 0.265). Also, there was a diminished inverse and significant effect of government agencies effectiveness (GAE) on the relationship between haphazard construction practices (HCP) and delivery of private housing projects, GAE x HCP ->DVL_ HP:(β = 0.261, P-Value = 0.000). The study recommends that building construction professionals and government regulatory agencies should pay more attention to the monitoring and controlling of private projects in the study area.
