Designing foundations for buildings and structures requires a wide range of soil properties defined by the requirements of Set of Rules (SR) 22.13330.2016 and SR 446.1325800.2019. Technical regulations for engineering surveys and design mandate determining soil characteristics through both laboratory methods and field testing directly in the field. Laboratory testing involves modeling natural and man-made processes in a different environment, within a confined space, and with several assumptions. When studying soil properties from borehole samples, it is crucial to consider that drilling and transportation cause core disturbance and decompression, which can distort the real characteristics. Even perfectly extracted samples cannot provide an exact representation of rock strength in its natural state. This is particularly evident when studying soils in Russia's remote regions. Field testing is a complex of operations that includes studying soils in their natural state using specialized instruments and rigs. Consequently, field methods provide more accurate results and more closely model the behavior of loaded foundations within the soil massif. The development and implementation of new field equipment is a vital contribution to the advancement of engineering surveys. Their importance in solving various engineering tasks cannot be overstated, as they provide the most reliable and accurate quantitative characteristics of rock properties in their natural formation and bedding.
