03How we work
So the work on site can keep moving.
01
Drawings through finish
Read the drawing, cut, assemble, weld, check, finish. That is the order on site.
02
Responsible execution
For the scope we take, we look after quality, safety and the schedule, whether under a main contractor or inside a factory.
03
Factory and construction site
Members are made in the Ashikaga factory. On a construction site we fit and weld them as steelworkers.
04
Japanese site standards
Foreman training, slinging, cranes and full-body harnesses. We work to the rules of the site.

04Safety and quality
Work clients are glad they entrusted to us.
We make a point of not causing problems and not creating rework, and we keep building that record as one team.
