On 24 June 2021, the Champlain Towers South building in Miami collapsed, resulting in the death of 98 people. The condominium had substantial concrete structural damagein its pool deck area, mainly from failed waterproofing. This damage was identified in 2018, with repairs estimated to cost USD$9 million, but they were never completed. Before the building collapsed, inspections were mandatory 40 years after construction, and every 10 years onwards. Champlain Towers South was in its 40th year...

On 15 April 1989, football fans were crowded and crushed against the high steel fencing in Leppings Lane Terrace at Hillsborough Stadium. Ninety-seven lives were lost due to this disaster. In a critical assessment of the disaster, ICE found deviations from the Guide to Safety at Sports Grounds concerning geometry, layout and spacing between barriers on the terrace. As these are necessary for adequate safety, ICE concluded it demonstrated “poor professional judgement”. A reportinto the disaste...

The report recommendedremoving perimeter and lateral fencing and called for all-seater stadiums, which revolutionised safety at football grounds and sport arenas. However, in 2021, the UK government announced that from 1 January 2022, standing will be allowed at specific areas of five designated football stadiums. This is part of a review of the banon standing in stadiums.

On 19 September 2017, a 7.1 magnitude earthquake hit central Mexico, killing more than 200 people and toppling dozens of buildings in Mexico City. It struck exactly 32 years after an 8.1 magnitude earthquakekilled more than 9,000 people and left 100,000 homeless.
What’s changed
After the 1985 earthquake, building codes changed and protections against earthquakes were established. But after the 2017 event, surveysfound that severely damaged structures corresponded to old seismic codes (1942-1976), highlighting that even after 1985, the city’s earthquake resilience wasn’t optimal. In fact, many damages and collapses were observed in buildings designed according to 1987 and 2004 codes, implemented after the 1985 earthquake. To avoid this extent of damage, studieshave r...

On 14 August 2018, after a strong summer storm, a portion of the Morandi motorway bridge collapsed, killing 43 and leaving 600 people homeless. Located in Genoa, the bridge was cable-stayed and featured single post-tensioned concrete stays and spans measuring over 200m. By 1979, the bridge's designer, Riccardo Morandi expressed concern about the rate of degradationof the bridge, citing the marine environment and nearby pollution as contributors. When investigators assessed the scene after the...

On 14 June 2017, the cladding on the Grenfell tower in London caught fire, resulting in 72 people losing their lives and untold trauma for their families and many others living nearby. The inquiry into the disaster found that the construction company had used cheaper, flammable cladding that’d even been prohibited in other countries. This highlighted failures across the construction industry in the UK, particularly regarding construction product regulation. The UK government commissioned Dame...

The Fire Safety Billwas introduced in 2020, amending the 2005 version. This bill should result in greater clarity over responsibility for fire safety in buildings containing more than one home. In 2021, the Building Safety Billpassed, seeking to verify the competence of built environment professionals and provide residents with more power in the decision-making process.
