Delivering High-quality Buildings and Infrastructures
This is a redevelopment project in front of Musashi Koyama Station on the Tokyu Meguro Line, the first district designated under the Tokyo Metropolitan Government's "Ordinance for Promoting Stylish Streetscapes in Tokyo". The complex project consists of three buildings, including a 41-story building with seismic isolation systems.
With the site being in front of the station, restrictions were posed on traffic flow lines and space of work yard, and in addition, the construction of another high building was underway on an adjacent site. The key factor was the progress control. Using our proprietary "Penta-Ocean Integrated Construction Management System (PiCOMS)", the progress of the precast work was monitored in real time by checking and sharing the progress data entered by project members and workers on site, using their tablet terminals and other devices. The system contributed to streamlining progress management, such as material delivery planning.
Furthermore, the management of the construction vehicles going in/out of the site was carefully discussed with the contractor of the nearby site, and the impact on the surrounding environment was minimized by separating flow lines. With the completion of this project, we achieved 1. improvement of the flow and circulations of visitors to the town, 2. creation of a lively atmosphere, 3. creation of new local communities and 4.contribution to the further development of the town.
Commitment to Client Satisfaction
In civil engineering projects, 97% of public work projects received a very high rating of 75 points or higher from clients. In private projects, all 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 3/23. 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. 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. We will strive to provide high-quality structures as a matter of course, while placing high priority on safety, health and environmental issues.
