    "description": "In relation to breakdown maintenance and noting the age of the equipment (1960's) the expectation would be the chosen supplier would hold or arrange preferential access to critical spare parts and have access rights to the NGET property as many of the connections are within NGET owned/leased and operated substations. <br/><br/>Work carried out on the majority of the High Voltage (HV) equipment will be under the NGET Safety Rules and requires their direct supervision.<br/><br/>This PIN provides procurement awareness for suppliers regarding this requirement. Any information gathered through this market engagement may inform internal business planning and any possible subsequent procurement process and will NOT be appraised in any future tender evaluation exercise. <br/><br/>Should this procurement be within in your company's capability and capacity we ask that you register your interest with the undersigned by the closing date. (Please note this is NOT a selection questionnaire, it is to enable Magnox to gauge the market interest and appetite for this procurement and to inform our procurement strategy).<br/><br/>It is anticipated that any future procurement will be run under Public Contract Regulations (PCR) 2015 Restricted Procedure.<br/>Following the closure of this PIN, it is Magnox Limited intention to hold a virtual supplier day for interested parties, which will provide a more detailed overview of our requirements and expectations.<br/><br/>As part of a restricted procedure, a Selection Questionnaire (SQ) will take place following the supplier day. Supplier(s) who are shortlisted as part of the SQ phase, may be invited to a further supplier day.<br/><br/>The dates relating to the publication of the contract notice are tentative and are subject to change.<br/>Tentative Timelines:<br/><br/>Prior Information Notice (PIN) - 27 October 2022<br/>Registration of interest -10 November 2022<br/>Virtual Supplier Day - Week commencing 17 November 2022<br/>PCR Restricted Procedure Selection Questionnaire - TBC<br/>PCR Restricted Procedure Selection Questionnaire evaluation - TBC<br/>Issue of ITT - TBC<br/><br/>You are requested to register your interest in the opportunity by Noon 10th November 2022 via the Magnox e-sourcing platform Atamis at the address mentioned above.",

However, over the years NGET have amended these to reflect the operational learning based on experience and development of best practice routines during execution of the work. NRS do not hold copies of these regimes and they will not be made available to a new supplier by NGET therefore any new supplier will need to develop a new regime based on the OEM specification. <br/><br/>NRS copies of the OEM specifications are incomplete with many OEM's either no longer trading or having been taken over so it may not be possible to obtain new copies. Any new inspection and maintenance regime would require NRS approval, however NRS feel there is limited inhouse knowledge on this equipment to do this.<br/><br/>NGET hold, have access to, and have the expertise to refurbish critical obsolete spares which NRS believe other economic operators would find difficult and cost prohibitive to replicate.<br/><br/>The equipment is housed at locations where NRS are not the leaseholder, and any other commercial operators will need to engage with NGET and Scottish Power MANWEB to gain access to Sub-stations and then require full supervision during visits for emergency call-out services, routine inspection and maintenance. NRS have been informed that any work would need to be carried out under NGET and Scottish Power MANWEB Safety Rules respectively which will lead to additional third-party cost, delays and significant sub-station access/escorting issues with regards to coordination of the additional contractors engaged in delivering the work."
