Investigating Construction Activity, Using Network Analysis Like the Critical Path Method (CMP)

Abstract

Managing construction work is the process of breaking down the structures of the construction, determining the relationship between each activity to be carried out, the duration that is needed for every activity, and the creation of a schedule that is flexible. Problems might crop up in most constructions such as an increase in the cost of the project, the project not being finished at the stipulated time (schedule slippage), limitation of resources, and so on. The aim of this study is to investigate a network construction at Keffi new market, using the critical path method, this study will investigate the time of completion of a project and estimate the earliest and shortest time needed to complete the project, identifying the critical and non-critical task activity, data collection from project supervisor at Canonic Consult Ltd. Considering activities such as identification of all the activities necessary for the project construction, precedence relationship within the stated task, development of the network diagram, estimation of the earliest start time (EST) and latest start time (LST), determining the task that is critical and non-critical to timely completion of the project (float task). The outcome of the study shows that the expected completion time for the project is approximately 10 weeks, exactly 67 days and the critical activities are Foundation, Electrical & Plumbing, Floor, and Landscaping. The Noncritical activities are Site Clearance, Setting-out, Columns, Framework, Brick masonry, Roof structure, Plastering, Door & window fixation, Painting, and Electrical fittings and their “total float” is 19,17, 18, 28, 19, 17, 32, 28, 32, 28 and 22 days respectively.
