Upstream Sales to Shift to Construction-Method Selection Based on the Five Fundamental Principles of Construction

「In the progress of our domestic business, as a result of our accumulated activities proposing construction methods and technologies, press-in installation of 900-mm-wide hat-shaped steel sheet piles into hard ground was newly included in the Ministry of Land, Infrastructure, Transport and Tourism's fiscal 2025 edition of the Standard Specifications for Civil Engineering Work Cost Estimation.」

「Going forward, we aim to create construction projects that address these industry challenges by strengthening our approach to project owners and designers from the planning stage, centered on the advantages of press-in technology supported by scientific evidence in the form of data and track records.」

「As part of its efforts to promote press-in technology worldwide, we opened RED HILL 1967 in May in Akaoka, Konan City, Kochi Prefecture. The facility is an information center featuring actual machinery, construction methods and structures under the concept that seeing is believing. It has welcomed many visitors since opening and has been well received. We will continue encouraging people from around the world to visit RED HILL 1967, understand and accept the advantages of press-in technology, and promote a global revolution in construction methods.」

「As part of efforts to move away from the principle of using earthen embankments, construction of an Implant Levee within the body of a river levee is progressing on the Kokubungawa earthquake and storm-surge countermeasure project in Kochi Prefecture. The plan is to monitor the behavior of the levee body, corrosion of the steel sheet piles and deformation over the long term in order to demonstrate the performance of the Implant Levee.」

「Regarding the failure of river levees, a cause of the frequent large-scale flooding in recent years, we are strongly appealing to the public that the essential purpose of levees is to protect people's lives and property and that they must be “responsibility structures” that must never fail. We continue to propose Implant Rock Levees persistently to the relevant ministries and agencies and local-government officials, and are pursuing fundamental measures.」

「Regarding river levees, which have suffered frequent damage from natural disasters in recent years, we are appealing to the public and persistently negotiating with the relevant ministries and agencies to abolish the Earth-Embankment Principle, which stipulates that levees must be built with earth fill, and are pursuing fundamental measures based on the Implant Method.」

「To help as many members of the public as possible understand the irrational state of national land disaster prevention, we began publishing and distributing on our website last December a booklet titled 『国土崩壊 –「土堤原則」の大罪–』 (The Collapse of the Nation – The Grave Sin of the “Earth-Embankment Principle” –), written by 北村精男.」

「Our group is promoting outreach to upstream industry participants, including project owners and consultants, to shift to method-selection criteria based on the aforementioned Five Great Principles of Construction, so that the latest and most appropriate construction methods will be selected in the future.」

「Our group will further promote the development and proposal of construction methods based on the Five Great Principles of Construction and continue expanding adoption of the Implant Method as a disaster-prevention technology.」

「To address this issue, we are undertaking the following initiatives to encourage a shift to method-selection criteria based on the aforementioned Five Great Principles of Construction: promoting outreach to upstream industry participants, including project owners and consultants; developing demonstration and visualization facilities to make the advantages of press-in principles easy to understand; and expanding the press-in industry's base in cooperation with the National Press-in Association, an industry organization, while working with the International Press-in Association, an academic organization, to clarify the mechanisms of press-in piles and the ground through empirical science.」

「To address this issue, we are strongly engaging with the construction industry as a whole, including by promoting upstream sales to project owners to encourage a shift to method-selection criteria based on the aforementioned Five Great Principles of Construction.」
