Towering Infernos Risk In Asia

Updated: Sep 4, 2021

Rapid economic development over the last two decades has made Asia fertile ground for Super Skyscrapers buildings, and the Property/Casualty premiums associated with them bode well for insurers. But underwriters should be careful not to underestimate the high rise fire risk and its potential for outsize claims.

Today Asia has more Super Skyscrapers buildings than any other region in the world. Super Skyscrapers of 250-300 meters now represent the mainstream building height range, accounting for 57.3% of the total. Not only that, but the construction of Super Skyscrapers over 400 meters has increased significantly, and in the future, such “ultra” high rise buildings will be concentrated in Asia.

According to the 2016 Review Report of The Council on Tall Buildings and Urban Habitat:

“For the third year running, the world has built more 200-meter-plus buildings than any other year (128), beating the previous record of 114 in 2015. The momentum of Asia (not including the Middle East) has been unyielding for many years, and 2016 only serves to reinforce this trend further. The region recorded 107 of the 128 completions for the year or 84% of the total...

“A majority of these buildings are located in China. For the ninth year running, China had the most 200-meter-plus completions with 84, representing 67% of the global 2016 total, and marking a 24% increase over its previous record of 68 in 2015.2 Thirty-one cities in China had at least one 200-meter-plus building completion, with Shenzhen outperforming any other city in the world, with 11. Trailing behind Shenzhen are Chongqing and Guangzhou, each with six completions, followed by Chengdu and Dalian with five apiece.”

In China alone, 35 buildings of over 500 meters were reported to be either completed or under construction in late 2015, and by 2025 there will be more than 1,300 Super Skyscrapers buildings built that are over the 150 meters mark.

While Super Skyscrapers buildings are mainly concentrated in Asia, more than 90% will be located in mainland China.

From an insurance perspective, however, insurers should view the impressive growth of Super Skyscrapers buildings in both number and height in the context of their potential for large-scale loss of life and significant Property/Casualty claims.

The charred remains of the Grenfell Tower residential building (68 meters/24 stories) in London, whereas many as 80 people perished, is a stark reminder of the human cost of a high rise fire; the insurance loss is likely to be staggering.

Several expensive high rise fire incidents occurred in recent years. For example, the media reported that Dubai-based Orient Insurance paid USD332 million to Dubai’s Emaar Properties, compensating the fire at the Address Downtown hotel (302 meters/63 stories) on 31 December 2015.

Such Super Skyscrapers building fires usually catch public attention. Widely reported Super Skyscrapers fires also occurred in Chicago, Caracas and Madrid, for example. But some less well known Super Skyscrapers fires occurred in China recently, such as the Beijing CCTV north peripheral building (160 meters/30 stories) fire in 2009, the Shanghai Jiaozhou residential building (87 meters/28 stories) fire in 2010 and Shenyang Royal Wanxin Hotel (219 meters/4 stories) fire in 2011.

All such fire incidents resulted in enormous economic losses and sometimes with a tragically high death toll.

Underwriting challenges

Super Skyscrapers buildings pose a significant challenge to the insurance industry; while events might be of low frequency, they can have very high loss severity.

Underwriters face numerous technical challenges when rating Super Skyscrapers buildings because they often have unique and novel architectural designs – for example, podiums, atriums, and multiple towers. The height of these buildings also increases fire exposure, which requires the underwriters to reasonably and realistically evaluates the effectiveness of fire prevention and suppression measures and the accessibility for firefighting. Such Super Skyscrapers risks always need to be assessed carefully with a technical survey report beyond mere visual inspection.

In addition to underwriting, claims management can also be very challenging. For example, it is tough to determine the damage to structural integrity, which complicates whether to repair or rebuild. The decision to rebuild translates into a total loss (or constructive total loss), so insurance underwriters need to consider a 100% fire loss for Super Skyscrapers buildings.

Another claims management difficulty is the myriad of different types of policies involved in a Super Skyscrapers building fire. In addition to the first-party property coverage and loss of life, a wide variety of Casualty and Liability insurances address t

hird-party elements, consequential loss, errors and omissions, law and ordinance, and various professional indemnity and guarantee issues.

All of the above insurance challenges and difficulties require a high level of professional expertise and technical knowledge to cope with higher exposure for Super Skyscrapers buildings.

Case-by-case codes

Fire safety for Super Skyscrapers buildings is a significant challenge for architects, engineers, property management companies, fire departments – and insurers. Even for buildings over a certain height, there are no proven building codes for fire in most if not all countries in the world.

Most countries adopt a case-by-case principle for Super Skyscrapers buildings and call for performance-based design.

For example, in China, building fire codes specify mandatory requirements and rules for buildings below 100 meters high and higher standards with five categories of special needs for those above 100 meters, up to 250 meters.

For Super Skyscrapers buildings, the code specifies firefighting access, refuge floors, rooftop helicopter pad, high fire resistance standards, and enclosed lift shafts, as well as vertical fire compartmentation. However, the fire code for buildings of over 250 meters adopts the case-by-case principle and requires performance-based design.

The China Fire Codes GB50016-2014 stipulate that buildings over 250 meters must comply with the existing fire codes. Plus, more vigorous fire prevention measures need to be adopted. Therefore, the fire prevention design should be submitted to the relevant state-level firefighting supervision department for a particular expert panel study before approval is granted.

In the last few years, some major cities in China that are home to Super Skyscrapers buildings – such as Shenzhen and Chongqing – have introduced their fire safety codes to design buildings over 250 meters.

Unique characteristics

Super Skyscrapers civil buildings have many unique characteristics, such as many occupants, longer egress time and distance, smoke movement and fire control. Once a fire occurs, it is likely to cause heavy casualties and tremendous property damage. Challenges include firefighting accessibility, fire compartmentation, particularly for the vertical fire spread, refuge and evacuation, water supply and pressure, emergency electricity supply, and others.

The increasing use of new materials for structural components, plastic insulation and facade also complicate fire prevention design and firefighting. In addition, the fire codes for Super Skyscrapers buildings are further complicated by other design codes, such as structural, anti-seismic, wind velocity, ground load-bearing, and their novel architectural design.

It is also a universal principle that Super Skyscrapers fire safety codes focus on life-saving in the event of fire rather than extinguishing the fire to protect the property – as should be the case. But it leaves the property of high rise buildings vulnerable and open for severe damage and even destruction in the event of a fire.

With more tall buildings altering the skyline in Asia and other parts of the world, safety code bodies, architects and construction firms, fire departments, insurance companies and the general public need to raise their awareness of Super Skyscrapers fire risk. In addition, all parties should be jointly committed to enhancing fire safety standards and implementing more robust risk management procedures.
