Part I of the article is a general discussion of the current laws covering the institution called “smlouva o dílo” (the “contract for a work”). It discusses the issue of defining the work, which has changed relative to the old Civil Code in that the work no longer needs a material expression. It also discusses the options for setting a price for the work, as well as the concluding of such a contract without setting a price. There is a detailed section on budget-based price determination, which is especially useful in the construction industry.
