The article presents an assessment of dust collection equipment in terms of technological, economic, and operational characteristics. The criteria for this assessment and methods for calculating indicators that characterize the effectiveness of its use in the reconstruction of buildings carried out in cramped conditions of urban development are determined. The development of design solutions for the reconstruction of objects should not reduce the level of safety of builders and personnel of the reconstruction object, as well as cause damage to the environment, in particular, air pollution with dust particles from construction processes. The introduction of cost-effective means of combating atmospheric air pollution in design solutions, as well as the effective organization of construction production, which reduces the environmental burden on the territory, will allow the contractor to increase its competitive advantage when participating in tenders and determining the contract price for the reconstruction of buildings. The choice of cost-effective protective measures will save costs, subsequently determining the profit from the reconstruction of the building. The economic calculation given in the article allows you to determine the amount of operating costs in each individual case, and make a rational choice from the economic point of view of purchasing and using equipment in the course of work.
