Foundation Design to Japanese Construction Standards & Practices -- 2

We need to take a European foundation design and redesign it to Japanese construction standards and practices. Chiefly the changes are use of different rebar sizes and bending rebar on site and welding the cage. Calculations to support the design in Japanese format are also required. The foundation is to support a tubular tower and is approximately 4m by 4m by 1m. All input loads to the tower will be provided. Please note that both Japanese language and accreditation as a Structural Engineer in Japan are required for this project.
