The procurement contact named on the official notice.

RWM requires a supplier to provide cost estimation and modelling support to the in-house Cost and Estimating Team over the next 3 years for the following components of the above scope • T2 Projects: this will largely involve supporting work package managers (WPMs) and project managers (PMs) with producing their baseline cost estimate at the work package or project initiation stage before handover to ongoing cost management.

There will be a small number of larger value (tens of millions of pounds) projects that will deliver scope in T2, these will require production of baseline cost estimate, including base estimate, uncertainty and risk, cost estimate report, verification and validation (V&V), approval; costing inputs to project business cases; supplier cost assurance / validation; responding to independent review queries and recommendations. • Large value T3 Projects: these projects could have a value of hundreds of millions of pounds and a duration greater than 10 years, deliverables will include costing inputs to project business cases, primarily production of baseline cost estimates, including base estimate, uncertainty and risk (schedule and cost quantitative risk analysis), cost estimate report, V&V, audit trail, approval, responding to independent review queries and recommendations, and evaluating supplier bids. • Tranches 3, 4, 5 and 6, at appropriate levels of detail given tranche 5 is expected to have a duration of over 100 years. • Overall GDF Programme Cost Model: the existing integrated GDF whole life cost (WLC) includes estimates for the facility construction, operation and closure for a range of scenarios and assumptions, these will need to be updated as site selection progresses and Programme uncertainty and options reduce. • Procurement "Should Cost" Models and bid evaluation. • Other cost studies to support the NDA Group and RWM
