「Since 2024, the method has been applied to 2 bridges. For the bridge where it was applied for the first time, the validity of the design is being verified through continuous measurement of the actual bridge behavior. Based on these initial results, the company is currently conducting various tests to improve constructability and plans to construct the third bridge in fiscal 2026.」

「By using high-strength concrete with a design standard strength of 100 N/mm2, this method can be applied to longer spans with a lower girder depth than conventional PC girders, which generally have a design standard strength of 50–60 N/mm2. The method was registered in the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS) in May 2023 and was first adopted for a bridge construction project ordered by a private company in July of the same year.」
The DAX Beam HC method achieved concrete progress through its NETIS registration and first adoption for a privately ordered construction project. - FY2019AdvancedAnnual report
「The company is also developing DAX Beam HC, an improved version of the DAX Beam method, and is working to make the method available in commercially available bridge design software to promote the adoption of DAX Beam HC.」
The company renewed the technical review certification for the DAX Beam method and is adapting bridge design software to promote the adoption of the improved DAX Beam HC technology. - FY2017First statedAnnual report
「At a public demonstration conducted at the company's technical research institute in December 2016, a flexural strength verification test was performed on a test specimen with a 12 m span, confirming that it had capacity exceeding the calculated value. Compared with conventional methods, this new method can reduce main-girder fabrication costs by 30% and construction costs by 10%, and is expected to be adopted as one option for constructing low girder-depth bridges in the future.」
