The work will support strategic service design, future capacity planning, vessel and timetable considerations, and wider investment planning. Forecasts are required for all 30 routes, with route-level forecasts for 25 routes and leg-level forecasts for five multi-destination routes. The required outputs cover passenger and vehicle categories, central, low and high scenarios, and a 30-year horizon. The work is delivered for CalMac’s network, with the stated delivery location in Gourock. This is a services contract, classified under CPV 72322000 for data services. The procurement reached tender: CalMac invited offers through an open procedure, with electronic submission in English. There is one lot and the buyer set the tender deadline at 11 September 2026, 12:00 UTC; bids were also scheduled to open at that time. The contract duration is 180 days from commencement, and bids must remain valid for 90 days after submission. The estimated contract value is £100,000. Variants are not permitted. Suppliers must submit fixed-price responses for the required pricing options and meet the stated mandatory technical requirements, including forecasts for every route, scenario analysis, methodology, assumptions and machine-readable outputs. The requirement is covered by the Government Procurement Agreement. This opportunity suits data consultancies and transport analytics specialists with demonstrable previous experience producing comparable demand forecasts. The successful supplier must have the capability and capacity to analyse historic ferry passenger and vehicle data available from 2007 onwards and produce forecasts at network, route and individual-leg level. It must handle a 30-year horizon, passenger and vehicle categories, unconstrained demand, and central, low and high scenarios. The commission also requires a proportionate explanation of historic-data adjustments and limitations, a clear methodology, assumptions register and confidence commentary. Deliverables include machine-readable forecast files with a data dictionary, a final report and a walkthrough or knowledge-transfer session. Suppliers should be able to provide complete compliance evidence and fixed-price options. ## Notice CalMac Ferries Ltd (CFL) requires an external supplier to produce robust, transparent and usable long-range unconstrained forecasts of passenger and vehicle demand across the ferry network. The forecasts will support short, medium and long-term planning, including strategic service design, future capacity planning, vessel and timetable considerations, and wider investment planning. ### Lot Information Lot 1 CalMac Ferries Ltd (CFL) requires an external supplier to produce robust, transparent and usable long-range unconstrained forecasts of passenger and vehicle demand across the ferry network.
