Abstract:

Some of the 21th century’s controversial issues in construction industry are inability in completing the projects in schedule or budget, insufficient architectural drawings (according to the owners), inadequacy in decreasing the waste, tremendous energy consumption of buildings and inefficiency in controlling carbon emissions from buildings. Nonetheless, adversarial relationships between participants are a fatal factor in any project’s success. Unfortunately, previous project delivery methods incapable of shedding light on these problems. Therefore, the Integrated Project Delivery system is developed in order to achieve a more suitable delivery system to overcome these issues. The system is introduced in order to decrease the adversarial relationship between parties, enable more collaboration of stakeholders, optimize the resources and material consumption and leverage the performance of labor in conjunction with taking recently emerged building information modeling technologies and lean construction principles as catalyst. Limited vi applications of IPD have been seen worldwide and although increasingly adopted in the United States, its application in Turkey and the Middle East has not commenced yet. There are some impediments to IPD’s wide use such as risks in relations, the need for a new legal framework, difficulties in close partnership and need to new competencies and skills. In order to support embracing of IPD in Turkey and Middle East, a survey has been conducted by AEC industry professionals. Respondents consisted of experts and professionals whom are experienced or informed about Integrated Delivery Method and Building Information Modeling applications in construction projects. This study aims to investigate the attitude of AEC professionals toward IPD as well as to identify obstacles limiting the use of IPD. Moreover, the effect of BIM technology in promoting the development and implementation of IPD is investigated. The results show that industry has an interest and expect benefits from IPD. Almost 94% of all individuals eager to participate in IPD projects. According to our findings experts listed the main obstacles as fear of change, lack of IPD awareness and lack of appropriate legal structure for IPD. Therefore, some additional measures such as adequate introduction and promotion, whether by education system or true advertisement, appropriate legal regulations and supports should be taken to make use of IPD possible in Turkey and Middle East’s AEC industry. Findings indicate that most professionals prognosticate that IPD will hold about 5~10 % of the market within 5 to 10 years.
