Once drawing data, created using 3D-CAD, is loaded into VR software, it creates a three-dimensional construction image. Engineers then wear VR headsets, which allow them to “see” a three-dimensional image. By operating the controller, the engineers can freely move and magnify the construction image, examine it from all angles and verify how products in the drawings will actually look in three-dimensional space. We introduced the VR software in our design work last year, and so far, we have used the technology in four projects for verification at the design stage.

・Allows to check how a design will actually look once constructed from the eye level, for example how it will look when viewed from below.
・Enables to determine intuitively whether, for areas featuring intricate use of backing frames, stiffeners and panels, it will be possible for workers to gain access and carry out necessary work during installation.
・Reduces the risk of reworking, as it makes it possible to predict potential challenges and problems —which previously could not be discovered until installation.

In the project that was the catalyst for the roll-out of VR technology, the design included an area where multiple metal panels were densely layered in a narrow space (see below). The nature of the design made it challenging to determine, just by looking at the design drawings, whether workers would be able to gain access during construction. As such, we decided to use VR imaging to verify, visually, whether there would be space for hands to fit between the panels. This advanced verification process prevents potential reworking during construction.

KIKUKAWA has introduced the VR software as a verification tool for actual construction, in response to our desire to determine in advance whether it is feasible to install what is designed in our drawings. 

To generate VR images from the design drawing, it is imperative that we create 3D model. KIKUKAWA has already shown itself to be an industry leader in this area, having already put in place a 3D-capable system, and applying 3D-CAD design in multiple projects. As such, we have been able to enjoy a comparatively smooth roll-out of VR technology.
