A single hospital building has one set of services, one structural grid and one contractor to coordinate. The record for Gambat lists a medical college, a trauma centre, an OPD complex, a rapid response centre, a nuclear medicine, cancer care and research centre, and liver transplant, kidney transplant, burns and bone marrow transplant centres, on one campus.
Those are not variations on a single building. A transplant centre, a teaching college and a trauma centre have different servicing demands, different clinical adjacencies and different construction sequences, and the hard part is the ground between them rather than any one of them.
At Gambat that ground sat inside one practice. The services recorded against the commission are master planning, architecture design, structural engineering, MEP engineering, road and infrastructure engineering and project management, all under a single appointment. The interfaces that usually generate the arguments, and the variations, were internal ones.
