Market of private works

The rules governing the settlement of contracts vary according to the nature of the contract between the client and the lessor. While the lessor is liable for all services rendered in accordance with the agreed prices, whether unitary or lump-sum, and cannot in principle call them into question on the pretext of an error in price calculation, or an underestimation of the costs incurred in carrying out the work, However, the consequences of alterations to the contract will differ according to whether it has been awarded on a fixed-price or lump-sum basis, or whether it has been awarded on the basis of a series of prices, or according to any other method involving unit prices on the basis of which the prices of the work will be settled.
