Moriyama Teshima Architects opposes 'shock' closure of Ontario Science Centre in new letter

2024-06-26T15:26:00-04:00

Moriyama Teshima Architects has provided a statement in rebuke of the sudden closure of its late founder Raymond Moriyama’s beloved Ontario Science Centre in Toronto. The closure was announced Friday by the provincial government, citing the need for repairs in many of its RAAC roof panels in the interest of public safety.

The issue is another salient note in the controversial Ford administration-led plans to remove the structure as part of the proposed redevelopment of Ontario Place and has been called into question by critics Alex Bozikovic and Elsa Lam. Each responded with the position that the government's reading of the engineers' report is wrong and meant to favor prospects for a new development.

"The Rimkus engineering report makes it clear that closing the OSC is not a necessity," the letter states decidedly. "Repairs are needed, but on a manageable scale and with potentially minimal impact on the public experience of the building."

Legal challenge to block Toronto's controversial Ontario Place redevelopment fails in court

2024-06-24T17:06:00-04:00

The Art Newspaper is reporting on the failure of a legal challenge that would have blocked Toronto’s controversial plans to realize a massive spa complex on the site of Ontario Place after the provincial Superior Court of Justice’s June 11th decision.

The project is contentious on both heritage and environmental grounds and has likewise drawn ire from its reported costs north of $650 million CAD ($476 million USD) to taxpayers. Therme, the company behind the plan, had previously signed a 95-year lease with the city government.

The removal of Raymond Moriyama's Ontario Science Centre, which is at the heart of the issue, is also stirring debate after it closed abruptly last week over fears of collapse stemming from the flawed RAAC concrete materials used in its roof. All this is "based on a faulty business case" says a closer analysis from Elsa Lam.

As the UK’s Raac problems grow, concerned educators complain of a stalled government response

2023-12-27T18:00:00-05:00

The number of schools with reinforced autoclaved aerated concrete (Raac), which the Health and Safety Executive has said is now 'life expired' and could collapse 'with little or no warning,' has been steadily rising since the government announced the sudden closure of more than 100 schools at the end of August, just days before the start of the new academic year.

There are now over 230 schools and colleges listed on the government’s register of buildings under consideration for Raac replacement and repair. The challenge is twofold at present, with contractors' inability to hasten repairs before 2026 being made worse by Prime Minister Rishi Sunak's cuts to the rebuilding program just weeks after it was initiated.

No one knows exactly what will happen to the endangered schools in the interim. An anonymous headteacher shared with The Guardian, “The best result would be rebuilding as we have so many problems, but actually we just need some certainty. Parents like shiny new buildings, and Raac definitely isn’t helping our reputation.”

The country's National Audit Office estimates the cost of repairs to be £2.2 billion (or about $2.81 billion USD) annually at present.

UK museums report new Raac concrete investigations as safety concerns spread

2023-11-09T14:01:00-05:00

The issue of unsafe concrete panels in the aging structures in the UK is affecting museums and cultural institutions who now report conducting their own building safety investigations after a spate of school closures linked to the issue first stirred controversy in August.

A report compiled by The Art Newspaper details efforts on the part of the Southbank Centre, Royal Academy of Arts, and others to document and deinstall reinforced autoclaved aerated concrete (or Raac) panels that have been proven to be susceptible to water damage and structural failures.

No use of the materials had been discovered in the Barbican Centre, Victoria and Albert Museum, British Museum, or newly renovated National Galleries Scotland, all four institutions independently confirmed.

Twentieth Century Society Director Catherine Croft told the publication: “There is an urgent need to understand where Raac was used, to examine whether or not it is now failing in each case, and then work out how best to repa...

Over 100 schools close in the UK over concrete safety concerns

2023-09-08T11:41:00-04:00

More than one hundred schools and education settings in the United Kingdom have been closed due to concerns over the integrity of concrete roof panels. So far, 147 schools are known to contain reinforced autoclaved aerated concrete (Raac), with approximately one hundred fully or partially closed, impacting more than 100,000 students at the start of the new school year.

The latest developments began in August when a Raac panel collapsed in a school in England, prompting a wider government review. While 147 schools have been identified as containing Raac, education unions warn that “hundreds more” schools could be impacted. Meanwhile, thirteen universities have closed or partially closed, alongside a number of theaters and cultural venues that have closed as inspections continue. The Guardian additionally reports that the number of UK prisons containing Raac may take two years to identify.

Raac, also referred to as “aircrete,” was utilized from the 1950s to the 1990s in UK public buil...
