Aperture (delay) occurs in almost every building project and their magnitude vary considerably from project to project, ranging from a few days to years. Construction aperture (delay) is the most critical factor affecting the delivery of construction projects in terms of time, budget and the required quality. This study examines the drivers of construction project management aperture and their significance to the goal-outcome gap in residential real estate investments. The study adopted survey approach, using a structured questionnaire to collect data from primary sources. The population of the study was 29 abandoned construction projects in metropolitan areas of Enugu, Nigeria. Purposive sampling was employed in accessing the sampling frame of 86 consultants, contractors and subcontractors registered with Real Estate Developers Association of Nigeria in Enugu. Data was analyzed with factor analysis and multivariate regression analysis at a significant level of p<.05. The study revealed that the predictors of goal-aperture in residential construction projects in the study area are financial problems (8.409), poor site management and supervision (4.318), covid-imposed global financial crisis (3.761), delay in reviewing and approving design changes (3.108), inappropriate construction methods (2.570), lack of capable representative (2.408), on-site accidents (1.418), and unreliable sub-contractor (1.176). The study also revealed that there was significant relationship between the failure predictors and the goal-outcome aperture in residential real estate investments (F=12.124, R2=0.766, p<.05 significant level). The study recommends that construction project managers should see the criticality of establishing synergy on the project site through the cultivation and management of team building and cohesion to ensure that every department of the project is aligned to the investment goal.
