The scope of this public procurement includes the following activities for each of the separated positions: Activity 1 - preparation of an investment project in the phase of technical project; Activity 2 - execution of construction and assembly works according to the approved investment project; Activity 3 - exercising author's supervision during construction. The full volume of activities for each of the separated positions is indicated in the Technical Specification, which also serves as the Assignment for the Design for commissioning the Investment Project. Due to the nature of the project and the specifics of the activities, the contracting authority (the municipality) is a different entity from the owners of the intervention site, as it performs commissioning based on the concluded contract. The contracting authority has limited the "maximum number of separated positions" for which a single participant can submit an offer, namely to two. The motives for this are dictated by several factors. Firstly, limiting the number of separated positions that a participant can engage in implies greater competition and admission of more economic entities, i.e., encouraging competition. Furthermore, it will ensure the successful completion of the construction by mid-2027, as required for "Just Transition". The measure is lawful and provided for in Article 46, paragraph 4 of the Public Procurement Act, possessing corresponding advantages over the possibility of limiting "the number of separated positions that can be awarded to a single bidder". The chosen approach allows for more realistic competition, as the risk of refusal to conclude a contract due to winning another separated position is minimized, placing the Contracting Authority, which "acts on behalf of the condominium," in a situation of relative dependence on the contractor's will.
