MESSAGE

Message from the CEO

A team of engineers
supporting building services.

Thank you for your continued support.

SETSUBI SEKKEI KIKAKU CO., LTD. is a specialist engineering firm that supports the quality and smooth progress of construction projects through building services design, cost estimation and shop drawing production.

In recent years, the construction industry has faced a range of challenges, including a shortage of engineers, increasingly complex work and shorter construction schedules. To meet these challenges, we have built a stable operating structure that combines the technical expertise and quality control developed in Japan with the talent and agility of our company in Vietnam.

Our engineers in Japan are responsible for client meetings, technical decisions, review of deliverables and quality control, working in close cooperation with our team in Vietnam. Rather than simply outsourcing work overseas, we operate as one team across Japan and Vietnam, making the most of the strengths of each. This is what sets us apart.

By handling design, estimation and shop drawings in an integrated way, we reduce our clients’ workload while pursuing the optimal balance of quality, schedule and cost. We are also committed to continuous training and technical development, aiming to be a partner you can rely on for many years to come.

We will continue to respond to our clients’ needs sincerely and promptly and, as a team of engineers supporting building services, contribute to the development of society and the construction industry.

We look forward to your continued support.
