Financing is crucial for the success of construction projects, which require a steady flow of funds to meet project objectives. Contractors in the construction industry face unique challenges due to the project-based nature of their work, significant financial requirements and a complex risk profile. An understanding of contractors’ financing methods is essential to ensure project success. This study focuses on the methods used by contractors in Oman to finance construction projects. Since commercial banks are the most common source used by contractors to obtain financial services, the study centres on researching the services offered by commercial banks for contractors and the requirements and difficulties associated with obtaining these services. The data collection was carried out using interviews and a questionnaire. A literature review was conducted to study contractors’ financing requirements, and an interview was conducted with the National Bank of Oman to identify the financial services offered to contractors and their related regulations. Then, a questionnaire was constructed based on the literature review and bank interview to identify contractors’ usage of financial services and the difficulties they face in accessing these services. The validity of the questionnaire content was evaluated by an academic professor and two experts in the construction industry. The arbitrators agreed on the same minor modifications. According to these suggested modifications, the questionnaire was updated and distributed online, primarily via Google Forms. Overall, 94 responses were collected and analysed using the SPSS software. Following the data analysis, three interviews were conducted with construction professionals to gain expert insights for the interpretation of the findings, understand the implications of the results and derive informed recommendations. The findings indicated that owner progress payments are the most commonly used source to finance construction projects, followed loans and bonds from commercial banks. It was also discovered that the high interest rates and fees associated with bank loans are the primary challenges contractors face in obtaining financial services from banks. The research findings will contribute to a better understanding of contractor financing sources, specifically focusing on the services extended by commercial banks and the obstacles encountered in accessing these facilities in Oman. This study fills a gap in the current literature concerning construction contractors’ financial practices in Oman. The thesis offers insights that may be advantageous for contractors and banks alike. Contractors could enhance their comprehension of banks’ loan assessment processes and lending policies, thereby bolstering their confidence in obtaining bank financing and improving their borrowing opportunities. Additionally, this research is valuable not only for foreign contractors seeking entry into Oman’s construction market but also for local contractors, particularly smaller enterprises, via enabling them to navigate the available options and comprehend the criteria governing bank services. Further, by understanding contractors’ viewpoints on the services provided, banks may gain key insights into the challenges faced by contractors, setting the stage for future research on bank services tailored to meet the needs of construction contractors.
