## Notice

LLW Repository Ltd trading as Nuclear Waste Services has a scope of work for the "Southern Trench Cap Interim Membrane (STIM) Replacement Contract", which forms part of the Repository Development portfolio of work at the LLW Repository facility near Drigg Village in Cumbria, England. The scope consists of civil engineering works associated with installing an engineered interim trench cap over the Southern Trenches. Repository Development is a long-term portfolio of works that will provide disposal capacity and protection of low-level nuclear waste over the next 107 years, or until the end life of the Repository Site. In the shorter term, the portfolio, over the next 15 years, will install closure engineering works for short and long-term environmental protection for wastes currently disposed in Vault 8 and the adjacent trenches. This scope of works has been previously referred to as Repository Development Programme - Tranche 1 Main Civils and has been communicated to the market in early 2022. The works over the next 15 years have been considered and optimised detailed designs completed. More recently, the delivery strategy for the works has been further developed and subsequently split into projects that deliver a key benefit to the closure of Vault 8 and adjacent trenches. This procurement is required to enable delivery of the Southern Trench Cap Interim Membrane Replacement Package for Repository Development within the Waste Operations Portfolio. The total estimated value of the 4 year contract is PS53m. The key scope elements are summarised in Appendix 3 - LLWR-RDP-T1.ST-SCO-001 - STIM_Scope. The Contracting Authority will procure for a Southern Trench Cap Interim Membrane Replacement Contract via the Restricted Procedure.
