Traditionally, pile load tests in Kazakhstan are carried out using static and dynamic load test methods. Static pile load test is the most reliable method to obtain the load-settlement relation of piles. Most of the static pile load tests are performed using reaction systems. Furthermore, cost and time for the static pile load test are relatively high compared to the dynamic pile load testing. Therefore, the number of pile load tests in construction site is limited to 2 or 5 piles in usual of constructed piles In Kazakhstan. This paper includes the short summary about dynamic and static tests by driven piles (cross-section 30×30 cm and length of 12 m). The methodologies of definition bearing capacity of the pile by aforementioned methods were also given. As an example for those methods, paper describes the results of the dynamic, traditional static and the new PDA (Pile Dynamic Analyzer) tests of cooperative work of soils and piles performed in the construction site of the New Railway Station in Astana. According to the results of tests were determined the possible depth of penetration and bearing capacity of piles, as well as recommendations on the device of working. The construction is part of the preparations for EXPO 2017. It will be 11 times bigger than the existing railway station. The height of the six-floor complex will be 49.5 metres, the width 116 metres and the length 630 metres.

The definitions methodologies of the pile bearing capacity by aforementioned methods were also given. As an example for those methods, paper describes the results of the dynamic, static and the new in Astana PDA (Pile Dynamic Analyzer) tests of soils by piles performed in the construction site of the "New Railway Station" (Fig. 1). The possible depth of penetration and piles bearing capacity were determined according to the results of tests, as well as the recommendations for the device of working piles of construction project were issued.
In similarity to every civilization in history originated from the riverside, the city of Nur-Sultan, which the new capital of Kazakhstan developed around the Ishim River. During the last 25 years, many high-rise buildings supported by pile foundations are rising in Nur-Sultan. The paper presents the monitoring of development for the unique residential building of 310 m high with 4-story underground parking. The pile raft foundation (for block R) analyses had designed using Geocthenical soft, which can assess in precise of the deformations, occurs in soil. In the paper presidents, method monitoring raft foundations for block R, the height of this block R is 320 meters. Design of distributed fibre optic strain sensing system (DFOSS) has been employed for measuring the strain in civil engineering structures for over a decade. It is now harnessed worldwide for monitoring a wide range of structures slab pile foundation. Geotechnical monitoring data of adjacent building and utility systems settlement caused by the construction of presented high-rise buildings were compared to numerical modelling results, predicted, and permissible values.
Finally, the raft foundation recommended for future high-rise buildings constructed of Nur-Sultan city on complex soils.
