| dc.description.abstract | The study examines the Empirical evaluation of Road Rehabilitation Projects (RRP) of Aba Owerri Road in Eastern part of Nigeria. The motivation for the study was due to deficiencies and inability of conventional Gantt chart scheduling techniques in addressing problems of time and cost overruns in road rehabilitation projects. Gantt chart failed to identify, isolate and exercise tight control on critical road rehabilitation activities that control the project duration. A total of four RRP identified to have suffered time overrun when scheduled and executed with Gantt chart were used for the study through experimental research design. The work breakdown structures of the RRP depicted in their respective Gantt charts were reschedule with an analytical tool of Critical Path Method (CPM). By inferential network analysis and results, the CPM easily displayed, effectively identified and isolated critical path activities which influenced and increased the project duration by seventeen months (15- 32) thus representing one hundred and thirteen percent (113%) upward review in project cost and time management. As part of effort to further confirm the results above, a more scientific approach was applied with the use of a micro software which also confirm the realistic project durations to be 32 months The conclusion is that it was obvious that work programme-chart (Gannt Chart) is reasonably effective only when applied to uncomplicated tasks, especially those involving a limited number of activity dependency, which means it cannot effectively handle the complexity inherent in most projects with a large number of activity. The study therefore recommends the adoption and institution of network scheduling technique (CPM) for scheduling of large scale RRP so as to complete the projects on schedule and contain cost and time overrun. | |
