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.

• Ground improvement

The choice of construction method not only affects the cost of the improved body alone but also changes the size of the foundation itself. The answer to "which is cheaper" varies depending on whether the size of the foundation is already determined. 1. Differences in bearing capacity change foundation design - Column improvement: ~300 kN/m² * Due to low bearing capacity, a large foundation is required. - Super Rappu Elneed method: ~1,000 kN/m² * High bearing capacity allows for a compact foundation design. 2. The competition for comparison occurs before the foundation size is determined Because the high bearing capacity allows for a smaller required foundation area, it becomes easier to achieve cost reductions that exceed the volume increase of the improved body. The Elneed method allows for foundation optimization at 10 cm intervals, which is a feature not available with column improvement. 3. Estimated cost comparison (based on actual results) Instead of using large specialized machines typically used for column improvement, we use a backhoe with excellent mobility. The diagram below compares the column improvement method and the Super Rappu Elneed method under the conditions of RC8F. As a result of optimizing the foundation size from the design stage, all excavation volume, material costs, and working time are compressed.

• Ground foundation construction method

This document summarizes the construction achievements and technical foundations for five challenging conditions in ground improvement that design offices, construction companies, and general contractors often find difficult to address and may decline due to "strict conditions." 【The five challenging conditions included】 1. Sites with groundwater or spring water 2. Muddy or weak backfill ground 3. Ground mixed with large gravel, boulders, and rock masses 4. Ground with undulating support layers that are difficult to verify 5. Remote islands, mountainous areas, and sites with difficult access For each site, it specifically explains why other methods (column improvement, rubble, cast-in-place piles) are challenging and how the Elneed method can solve these issues with specific technologies, along with the regions where these achievements have been made. The overall picture of the ground improvement method, with a cumulative construction record of approximately 4,000 cases by the National Elneed Association, a reinforced concrete ratio of 36.2%, and a site test body strength ratio of 1.0 or higher, can be understood in 9 pages.

Properties that are "vacant land delivery" appear to be ready for immediate construction. However, there are many cases where unexpected softness in the ground is discovered during the ground survey right after construction begins, significantly impacting the budget and schedule. ⬛︎ Why does "vacant land" become muddy? - Demolition contractors are professionals at tearing down buildings, but they are not experts in solidifying the ground. - Many sites are seen where the ground, which has absorbed water and become muddy, has not been properly treated, and only the surface has been leveled. ⬛︎ Three strengths of the Elneed method that is resistant to "mud": 1. An innovative approach to "manage and utilize" water. 2. Real-time responsiveness on site. 3. High mobility using general heavy machinery (backhoes). If you find yourself in a situation where "you bought vacant land, but the ground is mushy and heavy machinery cannot enter," please feel free to consult with us.

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. "What construction method is best for building this structure on this ground?" Please feel free to consult with us.

When considering ground improvement and foundation methods, the choice between "columnar improvement," "RAPPL method," and "El Nido method" significantly affects the size, cost, and duration of the foundation. ■ Differences in Long-Term Allowable Bearing Capacity of the Three Methods - Columnar Improvement: Approximately 300 kN/m² maximum - RAPPL Method: Minimum strength of 13,000 kN/m² - El Nido Method: Approximately 1,000 kN/m² maximum ⬛︎ Reasons for Choosing El Nido Using general-purpose equipment such as backhoes means that a smaller foundation directly translates to cost benefits. - Reduction in excavation volume → Decrease in disposal costs for surplus soil - Savings on material costs such as concrete and rebar - Shortened work time for excavation, reinforcement, and pouring The greatest strength of the El Nido method is that "design innovations are directly returned as cost benefits." The column also includes actual case studies for reference. Please take a moment to read it.

• Ground foundation construction method

Can we achieve an overwhelming reduction in construction time? ⬛︎Explanation 1: No "slurry production" (compared to cement milk/pile improvement) In the cement milk method and pile improvement, the process begins with "slurry production," where cement and water are mixed at a batch plant. In fact, this preparation alone takes about 90 minutes for a site using 30 tons of cement. The Super Rappu Elneed method eliminates this entire preparation process. Since the solidifying agent is directly inserted in its package, there is no need for a plant or slurry production. The insertion work that took 90 minutes is completed in just 5 minutes. ⬛︎Explanation 2: No "formwork assembly and dismantling" (compared to the Rappu method) In the Rappu method, after "excavation," "formwork assembly" is performed, and after the concrete hardens, "formwork dismantling" occurs. These tasks require specialized craftsmen and are time-consuming processes. The Super Rappu Elneed method utilizes the sides of the excavation hole as a substitute for formwork (earthen formwork), eliminating the entire series of tasks related to "formwork." This allows for reductions in work time, labor costs, and material costs.

I am anxious about whether we are truly reaching the "support layer" that serves as the foundation of the building. In other methods, the conditions underground can only be estimated from machine readings, making it difficult to determine their accuracy. The Super Rappu Elneed method allows us to "directly see and touch" the most important part of ground improvement. ⬛︎ The challenge of "invisibility" faced by other methods While other methods use specialized large machines to dig underground, the Super Rappu Elneed method employs the most common equipment on site, the "backhoe." Instead of estimating "numbers" like torque values or ammeter readings, we verify with the technician's "eyes." This simple and direct approach creates an overwhelming "certainty" that other methods lack. ⬛︎ "Visible reassurance" achieves optimization of quality and cost The advantage of being able to "visualize" the support layer goes beyond mere peace of mind. - Proof of overwhelming quality - Cost optimization - Prevention of troubles before they occur Because the work underground is invisible, we ensure reliable construction.

Ground improvement work in remote islands and mountainous areas. The biggest factor driving up costs is "transportation costs for equipment and materials." Our Elneed method (Super Laple method) solves this issue, which can sometimes amount to tens of millions of yen. The key is "overwhelmingly low equipment requirements." Since no special machinery or large-scale equipment is needed, transportation costs are dramatically reduced, making it possible to carry out projects that were previously abandoned due to unsuitable conditions. ⬛︎ Why is it "possible to construct anywhere"? 1. Only "backhoe" is needed. We do not use specialized heavy machinery like ground improvement dedicated machines. As long as a backhoe, which can be arranged anywhere, is available, construction can proceed. 2. Materials can be transported as "powder." Since we do not use ready-mixed concrete, there are no time constraints like the 90-minute rule to maintain quality. Cement-based materials can be transported in powder form and simply mixed with water on-site. This poses no problem even in remote islands or mountainous areas without ready-mix concrete plants. Thanks to this simplicity, we have successfully completed projects in more than three remote islands without regular shipping routes. Compared to other methods, we significantly reduce transportation costs and effort, contributing to the realization of projects.

• Ground foundation construction method

In ground improvement work on site, we will explain the differences between other methods and the "El Nido Method" from two perspectives this time. ▼Difference 1: Soil Disposal and Environmental Consideration▼ For example, in columnar improvement, it is common for the excavated soil to be discarded. As a result, the leftover soil is often treated as industrial waste, leading to increased disposal costs and greater environmental impact. On the other hand, the El Nido Method reuses the soil generated on site during excavation. The amount of leftover soil is about 35% for cohesive soil, and nearly zero for sandy ground. ▼Difference 2: Quality Control that Allows for "Direct Achievement" of Target Strength▼ In many ground improvement methods, there tends to be a significant difference between pre-mixing tests and actual on-site strength, necessitating a large safety factor due to variability in strength. For example, in conventional methods, the ratio of [on-site test specimen strength / pre-mixing test strength] is typically around 0.2 to 0.8. (Note: The "=" here indicates a range, so please recognize it as "nearly equal.") However, with the El Nido Method, we achieve [test specimen strength / mixing test strength ≧ 1.0]. In other words, the strength obtained on site is equal to or greater than that from the pre-laboratory tests.

**Challenges of Sites with High Groundwater** In construction and civil engineering sites, there are many concerns related to "groundwater," such as: - Groundwater springs up immediately upon excavation. - The groundwater level is high, preventing excavation to the required depth. - There is a risk of construction interruption or quality issues due to rainwater and other factors. - Particularly in cases where the groundwater level is high, it is not uncommon for traditional methods to be deemed "impossible to construct." **Reasons for Choosing the Elneed Method** ◎ Flexibility to handle groundwater The Elneed method incorporates an "adjusted water content ratio" in its mix design and manages the water volume within the fill using "flow values," allowing for the utilization of "sprung water and sudden rain." **Reasons for Feasibility of Construction in High Water Level Sites** - Adoption of excavation and mixing methods that suppress groundwater inflow. - Setting a higher elevation for the initial finish, then shaving down to the required height the next day to avoid the effects of water level. - Establishing a reliable construction system through quality assurance and N-value determination during the design phase. **Conclusion** Do not give up on a site just because the water level is high. With the Elneed method, construction is possible even under conditions of groundwater volume, groundwater level, and during the rainy season.

We would like to introduce the excellent economic efficiency of the "Super Rappuru Elniido Construction Method." Since it is constructed using direct excavation, it reduces the processes of excess excavation and the setting and removal of formwork. It allows for quick construction from excavation to completion at each site. Through numerous test constructions in various ground conditions, we have established know-how in testing systems, mix planning, construction management, and the development of mixing buckets, enabling us to create high-quality construction bodies with minimal strength variation. 【Features】 ■ Easy confirmation of the support layer ■ Shortened construction period and high-quality construction bodies ■ Minimal excess soil on site (amount of disposal soil) ■ Agile response to various sites ■ Capable of handling sudden rain and groundwater *For more details, please download the PDF or feel free to contact us.
