The "Super Rappuru Basic Construction Method" uses stabilized soil created by mixing construction-generated soil with water and cement-based solidifying agents, and is an improved method of the Rappuru concrete construction method for building foundations. The design utilizes various design standards based on the Japan Architectural Institute's "Construction Structural Design Guidelines," and similarly to the design of Rappuru concrete, it examines the ground bearing capacity and settlement based on boring data, determining the strength of the fill and the mixing plan (estimation). Prior to construction, on-site soil is collected, and soil analysis and indoor mixing tests are conducted to determine the mixing quantities and the effective range of flow values.

Boring surveys are an important means of understanding the ground. However, it is realistically difficult to fully capture the scattered boulders and cobbles, as well as the hard and uneven bedrock, from data points collected at only 3 to 5 locations. When unexpected issues arise on-site after the design has been finalized, it leads to a triple burden of changes in construction methods, extended timelines, and additional costs. This time, we will explain how to approach cobbles, boulders, and solid bedrock from the perspective of incorporating "uncertainty" during the design phase. 1. Why are boulders and cobbles "difficult to see in preliminary surveys"? Boulders and cobbles are typically distributed sporadically in river basins, fan-shaped deposits, and old river channels. 2. The significance of choosing a construction method that "allows for unexpected issues" during the design phase. The resilience to unexpected issues varies greatly depending on the construction method. 3. Solid bedrock can also be "cut and leveled." Alongside cobbles and boulders, the unevenness of the bedrock when reaching the support layer is also difficult to see during the design phase. When encountering hard bedrock with slopes and steps, many construction methods find it challenging to adapt. The Elneed method is designed with the assumption of changes occurring on-site. Being able to absorb this uncertainty regarding cobbles, boulders, and solid bedrock on-site directly contributes to the reliability of the design and the stability of the construction timeline.

The projects assisted by Elneed Kyushu have surpassed a total of 3,000. We will analyze this vast achievement through "numbers" and introduce why we continue to be chosen by many designers and contractors. ⬛︎ Breakdown of Structural Types - S-structure (Steel Frame): 51.7% - RC structure (Reinforced Concrete): 36.2% - Others (W structure, WRC structure, etc.): Approximately 12% ⬛︎ Distribution of Design Bearing Capacity (Long-term Allowable Bearing Capacity) - Volume Zone: 201–300 kN/m² - Corresponding Range: 50–1,000 kN/m² The reason we have continued to be chosen in this fiercely competitive area, where "ground improvement is considered to be below 300 kN/m²," lies in our high on-site responsiveness. ⬛︎ Responding to Evolving Needs In recent years, there has been a sharp increase in inquiries for high-capacity projects of 400 kN/m² or more. In this area, where general column improvements are difficult to address and ultra-high-strength methods (such as RAPL) tend to lead to over-design, the Elneed method provides optimal solutions.
