A number of international agreements are referred to as framework agreements: like a call for tenders for a contract, the framework call for tenders is generally a mixture of quality and price. The buyer then reviews all the framework offers and approves a number of bidders who receive a place in the frame. When defining framework agreements, buyers should be aware of the effects of limited competition associated with repeated purchases of the same products from the same suppliers over a longer period of time. It is therefore important that the benefit of building long-term partnerships is weighed against the benefit of opening up competition to potential new suppliers (especially SMEs) in order to keep pace with the continued development of the market. Framework agreements should be concluded where the buyer needs to establish a strategic relationship with the supply chain over a long period of time, allowing suppliers to adapt to the buyer`s requirements. The specifications and evaluation criteria are established in advance and cannot be changed during the term of the agreement, which lasts at least 12 months to a maximum of 3 years. After that, conditions and prices can be renegotiated to ensure that they are in line with changing market conditions. UNECE Recommendation 18 supports the implementation of such agreements. It also recommends that an intermediary providing trade and transport services within an international supply chain be, where appropriate, included in the framework agreement between the supplier and the buyer under a separate contract (measures 1.1 and 1.2). The competition can be done during regular periods (e.B.
annually) be considered for a framework agreement with a single supplier or be open at all times if more than one supplier is concerned. In the latter case, if necessary, price offers will be requested from all contracting parties and an order will be placed. There are many types of framework agreements that can be tailored to the specific needs of buyers. The most common use of a framework agreement is when there is no fixed schedule or scope for certain services. Unlike regular bids or tenders, once a company has secured a place in an agreement, it is likely that there will be no guarantee of the work, with the contract documents and conditions set. It requires a framework for the construction of units as part of a large construction program. Following a notice published in the Official Journal of the European Union and a selection procedure based on financial and economic and technical capacity, a framework shall be provided to a small number of main contractors for the units to be set up if necessary throughout the duration of the Agreement. .
