Abstract. Geodetic and geological surveys at a specific construction site form the basis for selecting technical and economic indicators and assessing their feasibility. Based on these, working and design documents for pile fields, road layouts, utility networks, and communications are prepared; an assessment of the stability of engineering-geological conditions is carried out; and the impact of pile foundations on existing structures and the surrounding area is checked, etc. The erection of a structure and its commissioning are contingent upon the execution of layout works. The most reliable foundation on weak and soft soils is considered to be a pile foundation, which consists of special vertical supports united with each other, driven into the ground until reaching the load-bearing stratum, with their tops above the ground. The upper part is called the pile cap and serves to evenly distribute loads during pile driving. This article provides an analysis of pile testing during construction. The magnitude of the final deviation of a driven pile depends on the accuracy of geodetic layout work, which is influenced by many factors. Piles are installed at the intersection of layout axes set out by a surveyor and are rotated around the longitudinal axis into a specified position. During the installation of each pile, the level of its deviation from the vertical axis is monitored. The pile driving process is controlled by as-built surveying. The maximum permissible deviations in plan and in height should not exceed the allowable values regulated by normative documents. In cases where piles are not driven to the required depth and it is possible to access the site, a pile-driving rig is used; if such an opportunity does not exist, the pile top is cut to the design elevation; otherwise, they are extended by concreting. During the work, deviations exceeding the permissible values were identified, which led to the expansion of the pile cap.
