Evaluating the effect of the construction rework on the performance and productivity of Sudanese projects

Abstract

Reduce the rework in construction is one of the active ingredients to improve the performance of construction projects in terms of productivity and costs, project scheduling , quality and safety . So with the existence of programs to reduce the rework in construction to meet this challenge. However, we need to the presence of studies for analysis and continuous improvement to reduce construction rework in this research we reviewed some charts that show the etiology main lead to rework and its impact on productivity and performance in construction projects in Sudan and that access to the scheme can find out the main causes for the rework, as well as its impact on productivity and performance. Some appropriate solutions to reduce re- work to improve the productivity and performance of construction projects in Sudan. We have arranged a contribution to the etiology of most contribution to the least through a case study for the 30 construction projects in Khartoum, Sudan, where the questionnaire included three axes 1/ personal information 2/ rework causes 3/ appropriate solution. The results were that most of them had weaknesses and strengths where most of them have a problem in the planning and scheduling of projects which has a big role in the construction rework. As well as the most of them take preventive measures to reduce rework, but not sufficiently so we made some solutions that will help to reduce these reasons.
