The methodology of numerical experiment of laying with closed method by methods of horizontal-directional drilling, brown-screw drilling, forcing, microtonneling has been developed. Some features of the construction of cases for penetration by collectors under existing highways, including general information about the used materials of the cases, are given. A selection of controlled factors and experiment planning, system stability check, results reliability analysis was performed.

The modern problem of building of big cities consists that there is almost no place left for the free building. Therefore it is necessary to carry out so-called "pointed building" when construction is conducted in the constrained conditions. At the same time very often construction sites get to an area of coverage of the subway that causes particular difficulties at construction of constructions in deep ditches.

The problem of determining the environmental hazard in the development and disposal of oil contaminated soil at the time of construction of buildings and structures is very relevant, especially for sites on which previously located industrial zones with different production. Unfortunately, at the moment, there is no clear understanding of the MPC of petroleum products in the ground. Various inspection inspections and specialized landfills treat the degree of soil contamination with oil products in different ways. In this regard, there is a danger of incorrect definition of the hazard class of the soil, which can lead to subsequent pollution of the environment.
