SWCC achieved drawing-free 3D design for construction at a TEPCO Power Grid substation. It announced this as the first case of applying its proprietary ADitor 3D design system and the PIM concept to on-site planning.
SWCC announced on 29 October 2026 that it had conducted construction planning using ADitor for the first time at a Tokyo Electric Power Grid substation construction site. This enabled an effort to shift design work centred on 2D drawings to drawing-free 3D modelling.
The background includes power infrastructure reaching the renewal stage, a shortage of skilled engineers due to the declining birthrate and ageing population, and growing demand for generative AI. Competitors are also advancing digitalisation, with Furukawa Electric investing approximately ¥100 billion to strengthen its optical-fibre production capacity, among other initiatives, intensifying competition to digitalise on-site operations.
ADitor generates a high-precision 3D base model from footage captured with commercially available cameras, enabling digital checks for interference between existing on-site equipment and newly installed cables. The aims are to reduce the work required to prepare drawings and conduct on-site checks, and to accelerate consensus-building through visual sharing among stakeholders.
In its medium-term management plan, Transformation for Growth SWCC 2030, SWCC has set out a policy of transforming itself into a company focused on solution proposals and expanding ADitor's application beyond substations to other facility renewal projects. Its adoption is expected to advance as a foundational technology for the digitalisation of infrastructure renewal and maintenance.
