The demolition work is due to be completed in a month's time
Demolition work in preparation for Bristol's £430m new hospital is well under way.
Buildings at Southmead Hospital, including the medical school teaching unit, have been knocked down in the past few months.
A North Bristol NHS Trust spokesman said the services they provided had been relocated.
The project brings together services currently provided at Southmead and Frenchay hospitals.
It is due to be completed in 2014.
The NHS trust has said the new hospital will replace some of the most outdated hospital buildings in the country with "state-of-the-art, patient-centred designs that will offer enormous benefits for years to come".
A spokesman said the trust had organised the relocation of services to permanent and temporary facilities before the developers Carillion started demolition work, which will be complete in about a month's time.
Ruth Brunt, chief executive of the trust, said: "This has been something of a juggling act, ensuring that services located on the footprint of the new hospital are relocated in time for the demolition work to get under way.
"We have been working with Carillion to ensure the temporary facilities are of the highest possible standard as services will be based there for the next four years.
"It is incredibly exciting to see work get under way after all these years of planning and to see our new hospital facilities finally begin to take shape."
