Advantages of the Trenchless Method of Laying Fiber-Optic Cable into the Ground By a Cable-Laying Machine

Taking into account the sequence of operations of the technological process of trench and trenchless laying of fiber-optic cable into the ground, labor costs are calculated, and economic indicators for both technical solutions are compared. The beneficiaries of this offer can be construction and installation organizations for laying fiber-optic communication lines, general contractors and customers (technical customers). As a basis for the calculations, the state element estimate norms for the installation of equipment in St. Petersburg (GESNm-2001 St. Petersburg) were used with the use of correction factors for the cost of installation work brought to the price level as of January 2019. The materials used in both technological processes were not used in the calculations, and the work performed or not performed, which does not depend on the choice of the laying method, was excluded. It is accepted that in both cases the cable is laid in a protective polyethylene pipe. Advantages may include minimization of labor costs, economic benefits, reduction of construction time, reduction of the number of executive documentation issued, and minimization of downtime risks associated with the inspection of works.
