In recent times, there has been an increase all kinds of constructions both local and foreign types in Isoko Community in Delta State, Nigeria, and the tools used are both local and foreign made.  Most of these construction activities going on in the Isoko communities are poorly managed 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.

There have been increasing construction activities in recent times due to technology explosion and various emerging construction designs. This increase has equally affected construction activities in communities in Delta State. Isoko, one of the communities in Delta State is made up of Isoko North and South Local Government Area of Delta State is one of the communities where construction activities gained high influx owing to the growing population and also well-established institutions like the polytechnics now Delta State University of Science and Technology and the Delta State University Campus and the existence of oil servicing firms in the localities no doubt attracts construction activities in the area.

Construction industry is undoubtedly complex in nature because it contains large number of project parties as clients, consultants, contractors, stakeholders, shareholders and regulators. The complexity and fragmented nature of the industry and its highly casual employment of labour makes it sensitive to poor contract performance. However, Babalola, Oluwatuyi, Akinloye and Aiyewalehinmi (2015) noted that poor construction performance has created economic situation which the industry cannot manage and at the same time the industry stakeholders or contractors do not know how to document these problems for future references. Despite this complexity, the construction industry plays a major role in the development and achievement of goals in the society. Construction industry is one of the largest single industries that contribute greatly to the development of nation. The pace of the economic growth of any nation can be measured by the development of the physical infrastructure such as buildings, roads and bridges (Takin&Akintoye, 2012). Successful building construction projects for instance, are those projects finished on time, within budget, in accordance with specifications and to stakeholders’ satisfaction (Ogunsemi, 2006; Yaman, 2007; Cheng, 2011).

In Nigeria for instance, the construction industry is a very significant part of Nigeria economy. Though contributed just about N627, 286.61 million (4.06%) and N 695,565.83 million (4.32%) as its own share to the nation’s GDP in the first and second quarters of 2014 respectively (Ogundele, 2010).  It remains a key player in the national economy. However, the construction industry inevitably faces many challenges which today’s construction manager needs to provide solutions to. Some are new to the industry, and some are centuries old. The nature of the industry further complicates these challenges. The industry is fragmented and often inefficient and is also slow to adopt, implement and integrate new information technologies and products, devoting few resources to research and development (R&D) compared to other (Adeyeye, 2009).
