Collaboration with Rendra AS on technological development for DX using BIM～Aiming at digitalization of construction processes using BIM cloud platform～

Takenaka Corporation（President：Masato Sasaki）is entering into a technological development collaboration arrangement with Rendra AS (Managing Director: Ole Kristian Kvarsvik, referred to below as Rendra）for the purpose of further accelerating digital transformation using BIM^*1.

To increase productivity at construction sites and to enhance the attractiveness of the construction industry, we have begun to implement drastic reforms　"advanced construction integration" in our business processes. One of the key initiatives is the digital transformation (DX) using BIM. As the core of these activities, we are developing "Open BIM," which links design data created with a variety of tools, and we will accelerate and broaden these activities further by promoting the StreamBIM-centered technological development.

“StreamBIM” is a BIM cloud platform that provides document and workflow management based on BIM models. It enables users to view BIM models on a variety of devices, including PCs, smart phones, and tablets as well as manage a variety of document information, including 2D drawings. In addition, by leveraging the information, it enables to facilitate and visualize the communication among all parties involved, from the design and construction stages to the facility management stages. We have already applied StreamBIM at more than 50 construction sites.

From here on, to further strengthen the link between "StreamBIM" and other solutions, both companies will continue on technological development. First, we will work to further improve the collaboration functions via BCF files^*2 with Solibri^*3 (Solibri, Inc), which we currently use as the primary tool for Open BIM, to quickly resolve issues on a variety of devices. Furthermore, through technical development, we will promote integration with various solutions such as the BIM data management solution "dRofus^*4" (dRofus Pty Ltd) and the 360° image management solution "HoloBuilder^*5" (HoloBuilder, Inc) to expand the use of data associated with BIM models throughout the project.

The importance of data utilization is increasing in the construction industry, and the concept of a common data environment CDE^*6 is defined in ISO19650-1,-2(2018)^*7.Takenaka and Rendra will continue to work closely to build a CDE enabling more efficient use of BIM models and for the sustainable ecosystem^*８ used widely in the construction industry.
