BIM/CIM APPLICATION TREND IN JAPAN
In Japan, the Ministry of Land, Infrastructure, Transport and Tourism has been dedicated to utilizing ICT (information and communication technology) to improve productivity in the construction industry. The BIM/CIM initiative was introduced in 2012 and has been verified step-by-step through trial projects. Since 2016, it has expanded as i-Construction, further promoting the use of ICT.
The BIM/CIM initiative aims to introduce a 3D model from the survey design stage and link and develop the model at each stage of construction and maintenance management. This will improve the work efficiency of the construction production systems, making the system more sophisticated and efficient. By shifting from 2D drawings to 3D models, the introduction of BIM/CIM is expected to bring benefits such as speeding up consensus building, improving operational efficiency, improving quality, and improving productivity through business transformation and front-loading.
From 2012 to 2020, 474 BIM/CIM trial projects were conducted for business and 418 for construction. As of 2021, there are more than 518 design and construction projects. Based on the knowledge gained from these projects, the “BIM/CIM Usage Guidelines (Draft)” was published to summarize the guidelines for creating BIM/CIM models and how to use them. These guidelines will be used for delivery of BIM/CIM models with guidance.
The “BIM/CIM Utilization Guidelines (Draft)” has a common version and a section for each field, such as Earthwork, Rivers, Dams, Tunnels, Mechanical Equipment, Sewerage, Landslides, Erosion Control, Ports and Harbors. The BIM/CIM model refers to a combination of “three-dimensional model”, “attribute information,” and “reference materials,” which are classified into structures and topography, and combined according to the model’s use.
