Images from an abandoned hospital were revealed after the £ 500 million reconstruction project broke off abruptly.
The equipment is covered with tape and material, the windows remain incomplete but the lighting is switched on in the shots.  The building of the Royal Liverpool hospital has become an empty 18-story building.
It was assumed that the NHS building was finished two years ago and it costed at least £ 400 million so far, with an additional £ 100 million to spend.
But the work stopped in January last year following a bad deal of private finance initiative with the collapsed Carillion company.
Although a new construction company has been named, the Liverpool hospital will probably not be finished until next year.
The bosses of trust are said to have had to employ 18 staff members now for turn the 4000 taps on and off regularly in an attempt to prevent the accumulation of lethal legionella bacteria.
Led to delays in caring for patients from the former Royal Hospital of Liverpool, which is the new hospital
Aidan Kehoe, CEO of the Royal Liverpool hospitals and Broadgreen University NHS Trust, said: "I am very angry at the the way Carillion behaved. "
Speaking at the BBC Hospital program, he added: "Leaving us in this position, I think, is unacceptable and I look at it and I think these people were taking huge bonuses that are not paying and will leave the residents of Liverpool waiting for years in more for a hospital, so serious questions you need to wonder how Carillion behaved. "
The building was also hit by floods in the last months.
The exact cost to the taxpayer of the new Royal Liverpool Hospital is unknown, as has been co-financed by private companies and the EU.
However, Liverpool Labor mayor Joe Anderson said, "I saw how bad the current Royal Liverpool Hospital building is.
"The last time I was there, the water was coming out of an air conditioner and they put a trash can down to get it.
"It makes me physically sick to see the state of the outside, and what the staff and the patients have to endure every day is terrible."
"I was not informed that Theresa May was visiting Liverpool or that she was invited to meet her, which I think is completely immoral.
"Exhibition is afraid of having a debate. If you had met with me, I would have requested emergency funding for the existing hospital site. "
But Theresa May visited the Alder Hey Children's Hospital last week, just three miles away, to launch her 10th annual NHS spending plan.
The Prime Minister has said how many medicines must become "personalized", ie tests will be done first to identify mutations in the genes and then use the most appropriate medicine.
He hailed the launch of the plan as "truly historic moment"
Speaking in Liverpool, Ms. May said: " The demand for our NHS services continues to grow waxes.  "Our health service faces growing challenges, from an aging population with complex health needs.
" NHS leaders have told us that making the necessary changes in technology, workforce and infrastructure will require time and careful planning and that is why the last year, in its 70th year, I am engaged in an ambitious financing proposal, to help make the NHS suitable for the future. "
