Papworth Hospital NHS Foundation Trust in the UK has called for bids for its £150m, privately financed hospital.
The 290-bed hospital will be built on an eight-acre plot at the Cambridge Medical Campus.
Papworth Hospitalwill be relocating to the new site in five years time, after which the existing site will be sold for redevelopment.
Work on the hospital is due to start in two years. Construction and commissioning is expected to take a further three.
