Abstract
Construction in Oman is an important sector that contributes greatly to the country’s economic growth. Recently, the construction projects in Oman have been delayed which has led to delays in the projects’ completion and sometimes to their failure. This study aims to examine the critical factors affecting the success of construction projects in Oman. The extent to which factors related to project parties affect this success was assessed. A quantitative approach based on systematic literature review and questionnaire survey technique was used. The factors were identified and classified into six main categories, namely, time; finance; project designing, planning and scheduling; quality; project progress and development; and environment and nature. The factors are also classified as client-, consultant-, contractor- and external-related factors. This study was conducted by distributing questionnaires to people who experienced working in the public and private construction sectors in Oman. Relative importance index method was used for analysis. Results show that quality is the most important amongst the six investigated categories, followed by time; finance; project progress and development; project designing, planning and scheduling; and environment and nature. The client-related factors have the highest impact on the success of construction projects in Oman, followed by consultant-, contractor- and external environment-related factors. The selection of a low bid, rather than accurate and reliable bids, and the quality and experience of the project team and labour are the most significant factors affecting the success of construction projects in Oman. The contractors’ administrative corruption, indiscipline and dishonesty and the frequent equipment breakdowns are the two least important factors affecting the success of construction projects. The government should encourage clients to improve their procurement strategies and force the construction companies to implement innovative approaches to project delivery.
