- ItemInfluence of Conflict Factors on Performance of Construction Projects(2022-09)Conflict is inherent in construction projects due to uniqueness, complexity and involvement of several stakeholders. Occurrence of conflicts affects projects outcomes if not properly managed. This study assessed (he influence of factors responsible for conflicts on time, cost and quality performance of construction projects. A quantitative approach which entails questionnaire survey was adopted. Data were collected through questionnaire administered to 125 construction professionals, out of which. 83 were properly filled and returned. The data collected was analysed using both descriptive and inferential statistics. Influence of the conflict factors on project performance parameters was ranked using mean and standard deviation. Kruskal-Wallis Test was used to determine the statistical significance of the variation in influence of the conflict factors on lime, cost and quality performance of construction projects. Results indicated that the influence of all the 21 assessed conflict factors ranges from 'moderate ' to 'high '. 15, 13 and 13 factors have high influence on time, cost and quality performance respectively. Findings of the study also indicated that the variation in the influence og' conflict factors on time, cost and quality performance of construction project was statistically not significant (p value obtained is 0.286 for P< 0.05). The study concludes that 13 conflict factors have high influence across time, cost and quality performance of construction projects. Furthermore, the influence of conflict factors on time, cost and quality performance of construction projects is similar. The study recommends that construction stakeholders should strive to minimise the occurrence of factors which give rise to conflict in any given project so as to achieve optimal project performance.

- ItemASSESSMENT OF BARRIERS TO RISK MANAGEMENT (RM) IMPLEMENTATION IN SMALL CONSTRUCTION PROJECTS IN NIGERIA(2019)Managing project, risk in construction is becoming increasingly critical for ensuring that project objectives are met effectively. Due to the innate characteristics of small construction projects, they are prone to more risks as they face more challenges than the large ones. However, previous studies indicated that the Small and Medium Companies (SMCs) mainly contracting small projects did not attach adequate importance to Risk Management (KM) in small projects. This study investigates the; implementation of KM in small construction projects in Nigeria in terms of barriers to its implementation and measures for overcoming them. A structured questionnaire was developed and used to collect data from construction managers. The data were analyzed using both descriptive and inferential statistics. The findings revealed that lack of knowledge and experience, tight schedules and cost of project are the major barriers to KM in Nigeria. It was seen that contractors bid for projects without KM implementation which in turn affects their profit margin. More so, the attitude of construction participants is another problem to risk management. Increases in understanding of the concept of RM by managers is viewed as the most effective measure for overcoming lack of implementation of KM in small projects in Nigeria.
- ItemAN ASSESSMENT OF THE IMPACT OF PROJECT RISK FACTORS ON PROJECT COMPLETION TIME IN NIGERIA(2021-02)Completion time is an important criterion for determining construction project success. Many construction projects are completed behind schedule as a result of various risks involved in construction projects. Performance of project completion time can be improved if the risk factors that could cause delay are evaluated and managed. This study assessed the impact of project risk factors on completion lime of construction projects. Data was collected using structured questionnaires administered to 192 construction practitioners. 138 questionnaires were duly completed and returned but only 114 (59.38%) were found fit for analysis. Descriptive statistics was used to analyse the data. The study identijied financial difficulties of owner' (MS = 4.35), 'inadequate time estimate' (4.33), 'delay in progress payment by owner/client' (4.23), 'poor labour productivity' (4.22), 'shortage of skilled labour' (4.18) and frequent design changes' (4.05) to be the topmost risk/actors that impact on project completion time. The study concludes that financial', 'design' and 'contract administration and project management' related factors group are those with high impact on project completion time.
