Performance measurement of construction projects managed by ISO-certified contractors in Khartoum

Abstract

Today, getting a high quality project is a necessary requirement for both the owner and the executing companies, so all companies are seeking ISO certification, but on the other hand, increasing competition showed another aspect other than quality, which is getting a high performance project which is almost a very difficult task. For the multiplicity of participants in the field of construction must therefore use performance indicators to ensure that the objectives of any project has been implemented as planned because the process of measuring performance is a tool used in the management of projects to evaluate the project and ensure that the objectives set have been achieved as required and planned. To determine the measurement indicators used to evaluate performance in local construction organizations in Sudan and to know the difference between projects implemented by ISO and non-ISO certified companies, 120 questionnaires were distributed to contractors, consultants, owners and other participants in the construction field 60 questionnaires were distributed to ISO certified companies and 60 questionnaires were distributed to non-ISO certified companies. About 74 of the questionnaires were returned, 61.6% of the total, half of whom were employed in non-ISO certified companies. Accredited by ISO and the other half are not accredited by ISO. The data were analyzed by statistical analysis using SPSS 2018.The results reveal that the majority of respondents confirmed that performance measurement indicators are sometimes used or rarely used in construction in Sudan and informally required to do so, but they are aware of the importance of use and one of the most commonly used indicators on both sides is the defects index. The satisfaction of the project team, and the safety index, they also confirmed that the companies that are ISO certified carry out high quality projects from their non-ISO counterparts This result gives a better look for the future study, especially on the impact of the use of performance measurement indicators in companies over the implementation of projects in the field of high-performance construction.
