### Practical Applications and Future Research  
This study presents a geomechanical and geotechnical analysis of an experimental field typical to Sao Paulo, Brazil. Recent studies demonstrate the use of this field, such as for characterization, monitoring, and modeling of pedestrian bridges [25; 26]. Additionally, the analysis and design of deep foundations for building projects with energy and heat exchanger piles are demonstrated in recent studies within the experimental field [28]. Furthermore, for future research, we intend to use and implement the Thermal Cone Test (TCT) within the area, utilizing the same equipment from the Cone Penetration Test (CPTu). For this purpose, the cone must be equipped with a temperature sensor, and the test must be paused at depths of interest so that the excess heat generated during penetration can dissipate and time and temperature data can be recorded for subsequent interpretation. In the case of soft soils or shallow depths, it may be necessary to heat the cone to generate sufficient heat for the dissipation test. This study performed a comprehensive geomechanical and geotechnical analysis of a typical Sao Paulo, Brazil profile. This research demonstrates the utility of the experimental

Although widely used, existing analysis methods have notable limitations, such as the Standard Penetration Test (SPT), piezoocone test (CPTu), and seismic CPTu. The SPT, while helpful in providing soil resistance data, can be highly variable and influenced by operator technique and equipment inconsistencies. Moreover, it offers limited information about soil stratigraphy and material properties. The CPTu test provides more detailed resistance variations and stratigraphic transitions but can be less effective in soils with significant heterogeneity or cementation. Additionally, seismic CPTu measurements, although beneficial for determining wave velocities and stiffness, may be constrained by equipment sensitivity and site-specific conditions. By addressing these limitations through our integrated approach, which combines multiple testing methods and real-world field parameters, this study contributes to a more accurate and reliable characterization of subsurface conditions. Our findings underscore the need for advanced methodologies and calibrated models to enhance safety and stability analysis of deep foundations. The findings of this study have significant practical implications for architectural practice, foundation design, and geological risk assessment. In terms of architectural practice, the detailed geotechnical and geomechanical characterization of the experimental site provides architects with critical data for designing structures better adapted to local soil conditions. Understanding the soil's behavior under different loading conditions ensures that architectural designs are safe and sustainable. Integrating various testing methods yields comprehensive soil profiles for foundation design, allowing engineers to design foundations optimized for both performance and cost. The reliability of the CPTu and S-CPTu tests in identifying soil stratigraphy and mechanical properties supports the development of foundation solutions that can withstand local geotechnical challenges, thereby reducing the risk of settlement and other foundation-related issues. Furthermore, the study's findings enhance the ability to assess geological risks, such as soil liquefaction, slope instability, and seismic activity. By providing accurate soil behavior data, the research helps predict and mitigate the potential impacts of these risks on built structures. This is particularly crucial for ensuring the safety and resilience of infrastructure in regions prone to geological hazards.
