Assessment of Construction Managers’ Competency Performance on Project Delivery in Delta State, (Case Study of Isoko Community)

Isoko Community in Delta State, Nigeria, has been receiving all kinds of constructions both local and foreign types are ongoing and the tools used are both local and foreign made.  Most of these construction activities going on in the Isoko communities are poorly management and monitored. Thus, the poor performance and inadequate management of construction projects has led to lapses in reliability resulting in unexpected events that suffice as failures and delay in project delivery.  Thus, the study focused on assessment of construction managers’ performance on project delivery in Isoko, Delta State. To achieve this, three (3) research questions and three (3) hypotheses guided the study. The study employed descriptive survey design. Population of the study was 169 registered builders, civil engineers, architects, estate surveyors, valuers and quantity surveyors in Isoko of Delta State. From the population, a sample of 118 was taken using Taro Yamane’s formular. The instrument used for the study was structured questionnaire constructed in a four Likert scale. This instrument was both content and face validated by experts in the fields of research and used for data collection. The reliability was done using the test-retest method from other local government other than the one used for the study. Thus, the reliability result was 0.73, considered reliable for the study. The data obtained from the questionnaire administered were analyzed using mean, standard deviation, and Pearson Product Moment Correlation (PPMC) and multiple regression analysis was used to test for the relationship between the variables. The results showed that the level of competence significantly affects construction managers’ performance on project delivery in the study area; success factor does not influence the construction manager’s performance on project delivery in the area of study. Given that success recorded in one project may not significantly influence the success or performance in another project delivery; and the effectiveness of construction managers on maintaining quality, cost and time within necessary boundaries significantly boost the construction manager’s performance on project delivery in the area of study. From the findings, it was therefore recommended among others that since the level of competence of the construction managers significantly affects their performance on project delivery, there is need to for them to always upgrade themselves, academically and professionally by acquiring more certification. Also, that awareness should be heralded to ensure gender balance in the construction management
