It is impossible to unite project and installation and construction works in one purchase as it can limit the competition. A conclusion of the Ministry of Economic Development is based on the Marine life protection act of the competition. Besides, the specified works are presented at the different markets and on each of them there are potential participants.
Court practice is ambiguous: there are two line items. It agrees the first to unite works on preparation of the project documentation and construction works in one lot illegally. It limits the list of procurement participants. It agrees "second" - legally if works are technologically connected.
The regulatory authority "can fine the company customer which will unreasonably include in one lot of work on preparation of the project documentation and installation and construction works" 10 thousand rubles.
