Influence of rework on the project performance

Abstract

Rework occurs as a result of demand for improvements by clients, revisions to the design, changes to the scope of project and other variations that are addition. As a result of these reforms, rework costs are on the increase and it has indirectly affected cost variability, project completion delays and construction project quality deterioration. This study aims to explore the influence of rework on the project performance and accessed the relationship between rework practices that related to client, design, site management, subcontractor and project scope as part of the project management practices in the context of the developer of affordable housing scheme. A structured questionnaire were used as the principal instrument for collecting data, the respondent are selected based on a convenient sampling methods. A total of 80 questionnaires were distributed involving project engineer, project team, site supervisor and internal staff of the organization. Descriptive and inferential statistic such as correlation coefficient and linear regression were used to analyzed the data. The findings of this studies revealed that rework practices and project performance had an inverse and significant correlation and all six (6) hypotheses drawn from literature reviews were accepted. The findings of this studies also proved that rework practices were gives an influence to project performance. Three main rework practices that influencing project performance are changes initiated by project scope, client and design. Therefore the application of Project Quality Management (PQM), Building Modelling Information (BIM) and proper rework management in the project were suggested as the containment strategy to reduce and eliminate rework practices so then the level of construction project performance can be enhance to the higher level that may benefited to all.
