Abstract: the necessity of planning and cost adjustment during construction works is substantiated. The article deals with the consequences of non-compliance with rules and building regulations, which lead to additional financial costs for repair and restoration due to the destruction of both individual structures and the object as a whole. System errors in construction technology during Foundation reinforcement and installation are revealed. Made normative calculations for the implementation of the construction project. The article consists of introduction, two parts and conclusion. In the introduction the necessity of monitoring compliance with industry regulatory legislation. In the first part of the article "cost Planning in construction" substantiates the need for business planning based on economic approaches. Options for the implementation of ecological and safe construction materials in the construction of buildings. In the second part of the article "analysis of deviations from standards in construction" a detailed study of the individual stages of design and construction of buildings, which revealed the harmful effects of both gross errors and minor deviations from the established building standards. Clearly confirmed violation of the rigidity and strength of the Foundation of the building due to non-compliance with construction technology during reinforcement and installation. The algorithm of engineering calculations for the construction of the foundations of the building: schemes of works on pouring foundations and the location of formwork elements, costing and schedule of construction works, ensuring the reliability and safety of the building during prolonged use. The conclusion contains the main conclusions of the article and recommendations on cost planning in construction. In work not only consequences of use of fire-dangerous materials at erection of walls of buildings are revealed, but also constructive recommendations based on knowledge of physical properties of the construction materials providing ecological safety are given.
