Abstract

Even though construction industry contributes significantly to the development but it faces many challenges including delay. There are several research works on the delay that focusing on delay factors globally including Saudi Arabia. Hence this study was intended to identify the delay factors faced by Makkah construction industry and also to establish structural relationship of the factors toward the construction delay. A literature review that was carried out and found eighty one delay factors recorded from previous research works carried out in different countries including Saudi Arabia. Based on these factors, a pilot study involved twenty eight construction experts who are working in Makkah construction projects was carried out to determine the factors’ validity and relevancy. Result has reduced to thirty seven factors which subsequently being used in actual survey questionnaire. Two hundred fifty questionnaires were distributed among construction practitioners in Makkah city. Only one hundred valid responses were collected and considered for analysis. Ranking analysis using Average index approach (AI) found ten most significant factors causing construction delay are Difficulties in financing project by contractor, Poor coordination between parties, Shortage of manpower, Delays in producing design documents, Improper planning and scheduling of the project, Delay in progress payments, Low productivity level of labour, Poor communication between parties, Unqualified workforce and Poor contract management. Then, the data were further used to develop structural relationship model of the delay factors using SmartPLS software. Based on the model, it was found that group’s factor which has the highest impact on construction delay with path coefficient β-value of 0.452 is the client and consultant group. Overall performance of the model can be summarized as having moderate explaining power ability with R² value of 0.197 which means that the model is valid to represent construction industry in the city of Makkah. By identifying these factors, it will provide awareness to Makkah construction’s community in avoiding any potential delay in handling their construction projects.
