Introduction. Light railway transport (LRT) is the name of the public transportation system that Astana is currently building. The LRT project on Astana’s difficult soils is discussed in the article. Due to problematic foundation soils, both of these larger projects employed piled foundations. Materials and methods. The bridge’s foundation was built using bored piles that ranged in length from 8 to 55 m and had a cross-section diameter of 1.0 to 1.5 m. Every bored pile has a design bearing capacity ranging from 4,500 to 9,500 kN. Results. The integrity test (ASTM D6760–08) and static load test (GOST 5686–94) findings for bored piles are presented in this study. Under those circumstances, maintaining the integrity of each bored pile’s concrete body is crucial. Use the cross-hole sonic logging method to verify integrity. At the moment, the most trustworthy approach available for evaluating the integrity of a dug deep pile foundation on a building site is cross-hole acoustic logging, a non-destructive testing technique. After installation, integrity examinations are frequently the most practical way to evaluate the condition of the shaft. Conclusions. The real site provided the results that were interpreted. Lastly, a few suggestions for testing procedures appropriate for Kazakhstan’s challenging ground conditions are made.
