The iconic Houses of Parliament in London are currently under investigation for the presence of reinforced autoclaved aerated concrete (RAAC), a material known for its potential to deteriorate over time and pose serious safety risks. This development has emerged following the government’s decision to order the mass closure of schools across the country due to concerns over RAAC.

According to a report by The Daily Telegraph, teams of surveyors have been dispatched to assess whether RAAC is present within the architectural framework of any parts of the parliamentary estate. These ongoing tests are intended to determine the extent of RAAC usage within the historic building.

The Commons Chamber, an integral part of the parliamentary complex, was rebuilt after World War II under the guidance of architect Giles Gilbert Scott. The reconstruction project, carried out by John Mowlem & Co., was completed in 1950. Subsequently, the Lords Chamber underwent renovation in the months that followed, with the Lords reoccupying it in May 1951. The Houses of Parliament hold a special place in the nation’s history and serve as the iconic backdrop for the UK’s political proceedings.

The decision to initiate this investigation comes in the wake of growing concerns about RAAC’s structural integrity and safety. The material has been linked to potential deterioration over time, which could result in structural instability.

In a related development, NHS England has also taken steps to address the issue of RAAC. Hospitals across the country have been asked to conduct surveys of their buildings amid concerns that there may be more sites with RAAC than initially suspected. This urgent review is aimed at identifying and addressing any potential risks associated with RAAC in healthcare facilities.
