The largest crane in Europe has been put up in South London, as work begins on a new helipad for a hospital in Tooting.
St George's will become the second hospital in the capital to have an emergency landing pad.
It will give victims of major trauma - like road accidents, falls and stabbings - faster access to potentially life-saving treatment.
Ria Chatterjee reports.
The new helipad - London's second and the first in South London - will support air ambulances bringing the most seriously injured casualties for emergency treatment at St George's, which provides the Major Trauma Centre for the South West London and Surrey Trauma Network.
Heather Jarman, Clinical Director for Major Trauma at St George's Hospital told us which patients will benefit from the new helipad.
The helipad will help save the lives of people living, working and commuting in London by significantly reducing transfer times to the Major Trauma Centre at St George's Hospital.
Patients with serious injuries, such as those caused by road accidents, shootings, stabbings, major burns and falls from height can be treated more quickly, rather than being taken to hospitals further afield, often flying over St George's.
The HELP Appeal, which has provided a grant of £1 million towards the construction of the helipad at St George's Hospital, is a charity established by the County Air Ambulance Trust.
It relies entirely on charitable donations and is raising much needed funds to help finance helipad facilities at key emergency departments across the county.
The Appeal provides non-repayable grants to hospitals looking to build their own helipads or update existing facilities.
Partly funded by The HELP (Helicopter Emergency Landing Pads) Appeal, a 25m by 25m helipad will enable seriously ill patients to be brought by air ambulance for treatment at the hospital's Major Trauma Centre.
A lift shaft in the middle of the wing is being built so that patients can be lowered quickly and smoothly into the hands of medical experts.
The helipad - which is due for completion in January 2014 - is being constructed by Miller Construction and will be the second hospital helipad in London and the first south of the river.
The Royal London Hospital has become the first in the UK to use a pioneering new device to remove kidney stones.
A tiny laser is inserted into the body - and breaks stones up into tiny fragments.
Surgeons say it's quicker, and less painful for patients, than conventional surgery using forceps.
The Royal London Hospital in Whitechapel has become the first hospital in the UK to pioneer new instruments to remove kidney stones. The tiny devices use a laser to break up the stones before they are sucked out.
