The paper discusses adverse atmospheric impact of earthworks during reconstruction and overhaul of trunk lines. The review of the trunk line insulation replacement process under normal and complex conditions helped identify the number of excavating machines adversely affecting the environment when operated simultaneously,. The point is made that the calculation of adverse impact should be performed in at least two stages to, first, estimate noxious emissions of operating machines and mechanisms; and, second, quantify the amount of fine-dispersed dust from cutting off the fertile soil layer, extracting the old pipeline, excavating the trench, leveling the trench bottom and other earthworks. It is further noted that the diversity of work techniques and the use of multi-criteria factors hinder the estimation of the adverse atmospheric impact of earthworks, as the engineering process does not consider the meteorological and other related conditions. Therefore, a “construction blockchain technology” (CBC technology) comprising GIS data is required. The CBC technology identifies the construction technologies, machines, equipment, mechanisms, resources etc., as well as software products to select the optimum work techniques, technology and organization, including scheduling. Over-all, the integration of CBC and BIM technologies should underline environmental safety of construction works including, among others, earthworks.
