Abstract
These days, we are facing a variety of small and large construction projects around us. One of the effective factors in causing the implementation delays of these projects in Iran is the problems caused by choosing how to design and implement services. Proper selection of implementation methods can reduce project execution time by up to 30%. One of these methods is design and construction (EPC), which has made the tendency of both parties to implement this method more tangible. One of the branches of this contract is EPC CONVERTED or conditional design and construction. Accordingly, the parties knowingly accept the risks and specific conditions of the project and play a more colourful role than conventional EPC contracts by changing and accepting responsibilities in each section of the EPC. In this research, which has been done from the practical type and from the case research method and based on the analysis of the collected data through interviews and questionnaires, attempt was made to identify the causes of the delay in the design and conditional construction, which is due to the lack of transparency of responsibilities and job description and the lack of necessary and sufficient authority of the contractor and provide solutions for delays. Elimination of part of the activities and changes in the schedule and resources allocated, high involvement of the employer during the project life and disruption of order and management of the contractor have been identified as delaying factors that can be identified by preparing transparent tender documents and determining job descriptions and The services strictly prevented them from occurring. Studies show that this contract has been implemented once in Iran and in the Sirajeh Qom oil and gas fields project, which shows that this contract is not recognized. Identifying delay factors and ways to prevent them will be helpful in creating awareness for users and promoting the ideal project.
