The Ministry of Land, Infrastructure, Transport and Tourism has announced further results on the application of BIM/CIM, which will become the standard for civil engineering and construction works under direct control. by 2023. The plan is to first prioritize and review measures to address reported inefficiencies in a customer survey. Many problems have been raised because 3D models and 2D drawings are not linked together, so we are considering trying the business of creating 2D from 3D. We will also expand the environment and learning opportunities for customers who handle BIM/CIM.
In principle, customers clearly state the purpose of using 3D models for each project/job. Intended use Low-barrier content is set as ``required items'' and more advanced content is set as ``recommended items.'' When we asked the ordering department at the Bureau Regional Development on the status of application in construction work as of December 2023, the most common required item was ``explain to workers on site'' and the most recommended item was ``confirm receive construction steps.''
In a survey of employees who had the opportunity to use BIM/CIM, some suggested that consensus building had become smoother through discussion between ordering parties, relevant organizations and Internal explanation from customers. consuming, it takes time to understand the many standards involved and now needs to create both 2D drawings and 3D models.
At the meeting of the BIM/CIM Promotion Committee, a government-academia-industry organization (chaired by Nobuyoshi Yabuki, professor at Osaka University School of Engineering), held on the 22nd, based on on the monitoring results, an expert said , ``Many confirmations were made at the construction step.'' , I would like to see this lead to the development of BIM/CIM combined with 4D timeline .'' It was also suggested that there is a need to verify how models from the design phase are transferred to the construction phase and improve future workflows.
