Impact of Rework on Building Project and Organisation Performance: A View of Construction Professionals in Nigeria
Rework has become a menace in the construction industry as it leads to undesired and unnecessary loss of efforts. It degrades project cost, quality and schedule performance, and it occurs at both the design and construction phases of construction projects. This study therefore examined the perception of construction professionals on the impact of rework on the performance of both the project and the performing organization. This was achieved by determining the most important effect of rework on project and organizational performance, and identifying variables in which the professionals view varies significantly. The study adopted a quantitative survey approach in which structured questionnaire was adopted as the research instrument. Mean item score was used in ranking the professionals perception of the effect of rework, and Kruskal-Wallis H test was used to identify the variables in which the professionals view varies. The study revealed that: rework has a very high impact of (MIS = 4.00) on project performance which results in projects over shooting their planned budget and planned duration, and degradation of project quality. Rework has a very high effect of (MIS = 4.04) on organizational performance leading to loss of profit/reduced profit, de-motivation of workers, and loss of future work/business. Disputes between contracted parties, design team dissatisfaction, de-motivation of workers and Fatigue are the factors in which the professionals’ view varied significantly. It was recommended that there is the need for the training of construction stakeholders on construction rework and other variables that cause projects to over shoot their budget, time and other resource.
