To ensure the safety of capital construction facilities, it is necessary to anticipate and predict risks at the planning and design stage. Risk forecasting is carried out in both quantitative and qualitative measurement. The accuracy of the calculations requires consideration of a large number of different risks, their causes, possible consequences and the likelihood of their occurrence. At this scale of input, traditional ways of calculating construction risks are costly in terms of money and labour, and can be very time-consuming. Artificial intelligence and machine learning technologies automate the process of risk assessment and calculation. With digital technology, all the factors arising during construction will be taken into account in real time. Despite a number of limitations in the application of this technology, this method is the most promising and increasingly widespread.

In the process of developing a plot of the junction field, the theoretical calculation of the load capacity and the permissible load on the piles is carried out, based on which the number of piles and their arrangement are decided. The results of theoretical calculations are in some cases underestimated when compared with actual values, and the application of theoretical calculation may lead to an increase in construction costs. The article examines the change of pile size and position in a swave field after the actual results of the field tests are obtained. The technical-economic comparison was carried out and the conclusion of the effectiveness of the adopted solution for the three designed houses was drawn.

The article shows calculation on the arrangement of the embankment and the design of reinforced concrete casings on metal staves for stairs. The dam boundaries are located on the territory of a residential complex with a large difference in height. The ground base is prosaic. Calculation of transfer of the soil from II type of drilling to I type by tamping method, which will ensure the strength and reliability of the body of the fill. Constructive actions to ensure resilience are described. The metal piles with forced connecting link and reinforced concrete coaxes in the form of a beam system have been designed.

The study is devoted to improving the methodology of calculation of structures for the impact of explosive loads, including aerial shock waves in UAV attacks. Modern modeling methods are analyzed, a calculation algorithm using non-linear dynamic approaches is proposed. It is shown that the use of spherical discrete elements allows a more accurate assessment of debris destruction and formation. The calculations presented confirm the effectiveness of the proposed approach.

The article is based on modelling several variants of information diagrams of a corrugated monolithic ceiling of an industrial building. The information model has been transformed into an analytical model. The comparative analysis of all calculation models was carried out visually and in numerical aspect. The efficiency of BIM-technologies in design with the application of software complexes «Renga», «CAPFIRR-3D» and «LIRA-CAD» is also considered in the calculation and construction section. The comparative analysis of three variants of the joints of the beams and the slab of the covering was carried out. The analysis of the stress-distorted state of the calculation circuit was also performed.
