Section IV: Procedure
IV.1) Description
IV.1.1) Type of procedure
Award of a contract without prior publication of a call for competition
Justification for selected award procedure:
Additional deliveries by the original supplier ordered under the strict conditions stated in the Directive
Explanation
The offline feasibility rig is required to be a replica of the existing plant system installed on the MSSS plant - which was supplied originally by ABB Ltd. Therefore, as it is a replica of an existing plant system, competition is absent for technical reasons and can only be provided by the original equipment manufacture. Regulation 32(5)(b) PCR 2015 applies (for additional deliveries by the original supplier which are intended either as a partial replacement of supplies or installations or as the extension of existing supplies or installations where a change of supplier would oblige the contracting authority to acquire supplies having different technical characteristics which would result in incompatibility or disproportionate technical difficulties in operation and maintenance).
