Abstract
The article discusses the directional drilling method when pipelines intersect existing communications. The use of an alternative type of engineering survey – GPR survey method – to identify hidden complications is justified. At the same time, the GPR survey excludes the discrete nature of the soil mass studies and gives us fully the geological characteristics for designing transitions by the directional drilling method.

Materials and methods
The authors used the actual data for one of the design objects “TomskNIPIneft” JSC and the results of the geo-radiation survey. The survey reliably showed the presence of compacted objects and decompressed zones. As a result, the optimal trajectory for the underpass was chosen by the method of directional drilling.
