Solmaz was appointed principal contractor for Timewalk: The Lost Civilisations Experience, part of Immerse LDN at ExCeL London Waterfront. The project transformed an existing car park level beneath the exhibition halls into a purpose-built immersive cultural venue, with settings based on Göbeklitepe, Babylon, Ancient Egypt, the Maya civilisation and Rapa Nui. Solmaz managed the construction and fit-out, coordinating the client, designers, consultants, AV specialists, artwork teams and specialist subcontractors. The works were delivered within a fourteen-week programme while the wider ExCeL venue remained fully operational.
