- Abstract:
- The construction system, as a fundamental pillar of any country's development, requires meticulous oversight and the employment of qualified professionals. The introduction of qualified contractors in Iran as a measure to enhance the quality of construction projects and eliminate unqualified individuals from this field has been a valuable step. However, legal and operational shortcomings, as well as challenges in the contracts between contractors and employers, have hindered the effectiveness of this role. This study aimed to identify and prioritize the challenges in the workflows of qualified contractors and propose solutions for their improvement. Key identified challenges include fluctuations in inflation rates, interference by unqualified individuals, particularly employers, in technical matters, corruption and bribery within relevant organizations, employers’ lack of managerial competence, and circumvention of regulations through signature selling and employing fictitious contractors in projects. The major challenges identified in this research were analyzed and assessed from various perspectives. Prominent solutions include delegating the responsibility of material procurement to contractors, with the costs borne by the employer; monitoring the presence and activities of contractors in projects by engineering system supervisors; and requiring contractors to guarantee the quality of completed work. The findings of this research can significantly contribute to resolving critical challenges in contractors' workflows and improving the overall construction processes of building projects in the country
