Creating the Future Together with Our Clients
In Europe and the United States, Quantity Surveyors (QS) play a vital role across every stage of a construction project—from planning to completion and even demolition—earning a well-established and respected position. Their commitment to fair, impartial, and transparent costing has long supported clients in making informed decisions. Observing this culture, I have often hoped that the profession of cost estimation in Japan would someday receive similar recognition.
In recent years, new procurement methods have emerged in both public and private sectors, accompanied by growing expectations for greater transparency in construction costs. As a result, service models such as Construction Management (CM) and Project Management (PM) have begun to gain traction.
At the same time, Building Information Modeling (BIM) continues to spread throughout the industry, demonstrating its powerful capabilities across various stages of construction projects and driving significant transformation within the cost estimation field.
To stay ahead of these changes and not be swept away by them, Suntec Equipment Estimation is committed to leveraging the expertise we have cultivated over the past 30 years and shifting toward client-focused services such as cost consulting. Achieving this requires not only the dedication of each employee but also flexible leadership, innovative ideas, and the courage to pursue new ventures—fostering a company where excitement and curiosity never cease.
Guided by our guiding principle, “Creating the Future Together with Our Clients,”
we promise to move forward as one united team.
