The problem of accounting for additional costs in difficult construction conditions caused by the lack of clear criteria and methods for justifying the coefficients of tightness is considered. It is proposed to abandon the use of standard coefficients and switch to the mandatory introduction of technological maps that make it possible to more accurately assess real costs and increase the transparency of the pricing process. This approach helps to reduce the risk of conflicts between construction participants, improve the quality of control and increase the investment attractiveness of projects.
