Pricing restrictions in construction during wartime

I see that for construction works funded by the budget or state enterprises, new rules for cost determination apply during martial law: for example, the profit margin is no more than 15% of direct costs, and material prices are only average market prices or no higher than data from a special database. If we conclude a contract for such construction now, what will happen if we accidentally specify a price in the estimate higher than that indicated in the Price Database or exceed the limits for profit or other expenses? Can the estimate or contract be deemed invalid, or can any penalties be applied because of this?
