Question: When does the new royal liverpool hospital open?

context: The current hospital, originally known simply as the Royal Liverpool Hospital, was designed to replace three other city centre acute hospitals that existed at the time – the Liverpool Royal Infirmary on Pembroke Place, the David Lewis Northern Hospital on Great Howard Street, and the Royal Southern Hospital on Caryl Street. It had been agreed to amalgamate the separate facilities on a site in close proximity to the University of Liverpool for the purposes of medical education and research. The site on which the current hospital now stands (on Prescot Street) was identified as part of the post-war regeneration of Liverpool. However, building on the main hospital did not commence until 1963. The first phase of the hospital was designed by Holford Associates and built by Alfred McAlpine between 1963 and 1969. The construction was plagued from the outset by problems of cost, time and quality, together with difficulties over fire certification due to changes in health and safety law whilst building work was ongoing. The second phase was completed and the hospital eventually opened in 1978.

Answer: Prior to redevelopment, the new Royal Liverpool Hospital opened in 1978, while it will open in 2022 after redevelopment. A major redevelopment of the hospital began in 2013 and was scheduled for completion in 2017, but construction problems and the 2018 collapse of main contractor Carillion pushed the estimated completion date back to 2022.
