Determining the effectiveness of the relationship between clients’ involvement and tertiary institutions building projects particularly in the Southwest region, is a crucial challenge as there have not been tangible attempts to empirically demonstrate how such involvement affects successful projects implementation. This study assessed effectiveness of clients’ involvement in projects life cycle of tertiary institutions projects delivery in South-West Nigeria. the study is aimed at improving the level of clients’ involvement in pre- construction, construction and post construction stages of tertiary institutions projects delivery. 405 copies of questionnaires were self-administered to construction projects stakeholders involved in the administration of tertiary institution projects in the South-West Nigeria while 290 copies of the questionnaire were retrieved representing 71.6%. The collected data were analysed using both descriptive (Mean Ranking and Relative importance Index (RII)) and inferential statistics (Partial Least Square in Structural Equation Modelling- PLS-SEM) with the aid of Statistical Package for Social Sciences (SPSS) and SMART-PLS. The study classified client involvement into time, cost and quality involvement. From the result of the study, timely provision of comprehensive control information at each stage of implementations process by the client leads to successful project delivery. Company’s reputation (dCIPLC8) was ranked highest from quality involvement group while accuracy of project cost estimates (DCIPLC 13) was ranked first in the cost involvement group. Timely provision of comprehensive control information at each stage of implementations process by the client leading to successful project (dCIPLC 10) was adjudged first by all the respondents. Ability to handle unexpected crises and deviations from the plan which affects the duration of the project (dCIPLC 12) was ranked second. The result of the multivariate analysis revealed that the exogenous construct of timely involvement group had a positive significant relationship with all of the endogenous variables of pre-construction, post- construction and construction phases of the project at 95 level (= 0.435, t = 3.197; = 0.524, t = 4.857; = 0.482, t = 4.526). The study also records a negative significant relationship between quality involvement groups and the endogenous variables of construction phase: ( = – 0.222, t= 1.875); post construction phase ( = -0.202, t = 1.977) and Pre construction phrase ( = -0.273, t = 3.015). The study concluded that involvement of client at each stage of tertiary institutions project will leads to successful project delivery.
