- Why no open competition
The works, supplies or services can be provided only by a particular economic operator due to absence of competition for technical reasons; Additional deliveries by the original supplier ordered under the strict conditions stated in the directive
- Published justification
The requirement relates to the continuation of existing electrical, remedial, snagging, labelling, energisation/de-energisation support, commissioning support and integration works being undertaken by Optimum Electrical Engineering Ltd on the ESS Active Cells Facility project in Lund, Sweden.
Optimum has been delivering the electrical installation and associated support works on site since the original competitively tendered arrangement. The remaining requirement is not a discrete new package of work that can be separated and competed without significant technical, safety, quality and programme risk. It is a continuation of ongoing works across partially completed electrical installations, live snagging, system interfaces, Quality Assurance handover, commissioning support and subcontractor Site Acceptance Test readiness.
The remaining works are programme-critical and directly linked to system readiness, commissioning, subcontractor SATs and handover. Re-procuring or onboarding a new supplier would create an intolerable risk of delay, duplicated cost, loss of technical continuity, quality assurance issues and potential disruption to other subcontractors. It would also introduce serious reputational risk. ESS is a major European research infrastructure programme and delays to the UK-delivered Active Cells Facility could impact ESS operational readiness and the UK’s reputation as a reliable delivery partner.
The new contract will be supported by a defined Scope of Work, managed through the contract documentation, Primavera P6 programme, electrical package snagging list and UKAEA instruction. This will allow UKAEA to control, instruct, prioritise and monitor the remaining activities while retaining flexibility to respond to emerging snags, system readiness, external supplier delays and commissioning requirements.
