Delivering High-quality Buildings and Infrastructures

Toyosu Senkyaku Banrai is a large complex built around the themes of "eating" and "relaxing", developed on a site adjacent to the Toyosu Fish Market. The facility consists of a high-rise hot spring building with an open-air bath, foot baths and a hotel etc., and low-rise commercial buildings reminiscent of the streetscape of old Edo (erstwhile Tokyo). It was a highly complex project with many constraints to construct narrow rectangular buildings very close to the property lines of the site, which had an approximately 4m height difference. Due to the complex building structure, each floor was constructed simultaneously. Given that the project had attracted significant industry attention, the construction progressed with close care and attention to the great detail, holding regular counterparty discussions and ensuring their full cooperation in various phases. Another focus was establishing smooth communication among on-site personnel. This was achieved by visualization of construction plans by utilizing BIM, labor-saving by adopting pre-casting of structures, and giving precise work orders per tablet terminals. The facility became a venue enjoyed by many tourists and local residents as the name “Senkyaku Banrai” (a place where thousands gather) suggests. As a new destination in Tokyo and a great addition to the Toyosu Fish Market, the facility will make a contribution to the further development of the local area.

Commitment to Client Satisfaction

The analysis results are communicated to branch offices and construction offices through regular civil-engineer meetings and project manager meetings. In particular, with regard to the lowly-rated items of the survey, we prepare materials for identifying the reasons for low grades and countermeasures for improvement to work out a company-wide solutions, in order to further enhance customer satisfaction.

In civil engineering projects, 100% of public work projects received a very high rating of 75 points or higher from clients. In private projects, 98% of our clients rated our services as "very satisfying" or "satisfying".

In our private-sector building construction projects, many of our clients rated us with "very satisfying" or "satisfying", with regard to the structures and buildings, the employees in charge of construction work and sales & marketing in FY 3/24. The reasons for satisfaction include workmanship, cost performance and design, etc.
The results of customer satisfaction surveys and construction performance grades are compiled and analyzed to identify highly-rated and lowly-rated items. We will strive to provide high-quality structures as a matter of course, while placing high priority on safety, health and environmental issues.
