    Brief

    London Underground Limited (LUL) intends to award a two-stage Design and Build contract to Costain Limited for the South Kensington Station Capacity Upgrade as a call-off under TfL's Infrastructure Improvement Framework. The project delivers an enlarged station featuring a new platform, extended ticket hall, step-free access from street to all platforms, and modernized station systems and staff facilities. The contract is structured in two stages: Stage 1 covers detailed design using NEC3 ECC Main Option E, and Stage 2 covers construction using NEC3 ECC Main Option C. LUL's initial commitment is limited to Stage 1, with progression to Stage 2 being optional and dependent on Stage 1 completion, affordability confirmation, necessary approvals, and satisfaction of contractual conditions. The Stage 2 price will be developed during Stage 1 and has not yet been agreed. The contract value stated includes an estimate for potential Stage 2 works and should not be interpreted as a committed Stage 2 price.
