A total of 173 bored piles with a diameter of 1.65 meters are planned for the two towers of “Aurus Residence” near Moscow City. The maximum drilling depth will be 57.9 meters, and the effective length of each pile will be 34.5 meters. Fensma representatives provided these specifications in an interview with the “Skyscrapers of Russia” channel, published on October 19.
The company is currently carrying out pre-construction work. According to its representatives, this phase is scheduled to last about 16 months. It encompasses the construction of the foundation and the underground portion of the complex—this timeframe should not be considered the time remaining until the completion of the towers.
The interview separately specifies the drilling depth and the effective length of the piles. Therefore, the statement “173 piles nearly 58 meters long” would be inaccurate: the piles are specified as 34.5 meters long, and the maximum drilling depth is 57.9 meters. The publication does not specify in detail the reference points from which these measurements are taken.
The piles are not driven into the ground here. First, a borehole is drilled; then, a reinforcing cage is installed, and the hole is filled with concrete mix. Fensma representatives emphasize that they monitor verticality, concrete quality, and compliance with design parameters.
Four drilling rigs, as well as cranes, excavators, and loaders, are being used to install the piles. The stated pace is about ten piles per week. Approximately 130 people are working on the site; once the project reaches peak activity during the zero cycle, the workforce is planned to increase to 150.
The project specifies an excavation depth of 25 meters. This refers to the planned depth of the excavation, not an indication that the soil has already been excavated to that depth. In an editorial addendum to the interview, the channel clarifies: the main soil excavation work is scheduled to begin no later than the 20s of November.
Fensma representatives report that work is proceeding on schedule, and the groundwork phase is estimated to take approximately 16 months. However, the interview does not specify the starting date for this period.

What Is Known About the Timeline
The target date for completion of the pile driving work—June 2027—is mentioned in the interviewer’s question. The same source also refers to the completion of the “retaining wall.” In the response, the company representative discusses preparations for winter conditions but does not specifically confirm this timeline.
The main new detail for those monitoring the construction is the specifications of the foundation for both towers and the stated pace of its construction. Based on this information, it is possible to track the progress of the underground portion of the project without confusing the completion of the excavation wall with the completion of the entire foundation.
