In 2017, one of the biggest economic sectors in the globe was the construction industry. Additionally,
the construction sector has been strengthened by Building Information Modeling (BIM), a potent combination of
technologies for design, construction, and management. Even after a project has completed its lifespan, BIM offers
substantial advantages, but the project is unable to reap these advantages due to the construction industry's inability
to successfully adopt BIM technology. This study's primary goals are to determine the most important obstacle to
BIM deployment and to rank them according to their relative influence on this problem. A thorough literature
research was used to perform the study and gather the essential data. The literature analysis produced a list of 37
barriers that prevent the construction industry from using BIM technology. For every barrier found in the literature
review, a relative rank was determined based on its frequency and relative effect. B17 (Social and habitual
reluctance to change), B19 (Traditional ways of contracting), B3 (Training expenditures and the learning curve are
too costly), B20 (High cost of software acquisition), and B33 (Lack of knowledge about BIM) are the five most
important obstacles to the adoption of BIM. B19 (Traditional contracting techniques), B17 (Social and habitual
opposition to change), B33 (Lack of BIM awareness), B2 (Inadequate BIM training), and B28 (Lack of BIM
expertise) are the five most significant barriers. The government and other project stakeholders must work together
to remove the barrier based on priority in order to reap the enormous advantages of BIM technology.
