Tender: Inside Controlled Area (In-SEP) Initial Decommissioning Operations – Provision of Up to 30 FTE Support

About

The Contractor is seeking a subcontractor to provide operational support for Inside Controlled Area (In-SEP) Initial Decommissioning (ID) operations, supplying up to 30 full-time equivalent (FTE) staff with a blue/white‑collar mix to be determined by the subcontractor. This EOI covers longer-term works anticipated to commence after a current contract in place until 31 March 2027, with an estimated duration of 24 months. Work will be carried out in existing and future In-SEP buildings and will support, build upon and improve the established ID capability; specific tasks will be set by the ID In-SEP, Delivery Board and locally at Plant Operations Control Centres (POCCs). Initial activities include waste removal, waste packaging and despatch, size reduction and deplanting (removal, lifting, size reduction and transport of redundant plant), with complexity expected to increase as the capability matures, subject to providing Value for Money. Subcontractors should anticipate tasks that meet the definition of 'Construction' (CDM 2015 Part 1 Regulation 2) and must incorporate appropriate management and supervision arrangements. The subcontractor is responsible for design of all temporary works (primarily access/scaffolding and potentially lifting plans), must ensure safe sequencing, integrate designs with the Contractor and Others, and submit temporary works plans to the Project Manager for acceptance prior to erection (Project Manager review up to 10 working days; no temporary works until authorised). Delivery is within a live operational environment and scope is subject to change.
