COVID-19 Contributed to Sharp Decline in Completed Skyscrapers in 2020

It’s a given that the coronavirus pandemic has had wide-ranging impacts on construction projects large and small over the past 10 months. So, what about the construction of new buildings that share the defining characteristic of being superlatively tall?

As detailed in an annual report published earlier this month by the Chicago-headquartered Council on Tall Buildings and Urban Habitat (CTBUH), newly completed skyscrapers experienced a global decline of 20 percent in 2020 compared to the previous year due, both directly and indirectly, to the COVID-19 crisis.

The Week in Architecture: Blue Monday and the Aspirations of a New Year

For those in the northern hemisphere, the last full week in January last week kicks off with Blue Monday - the day claimed to be the most depressing of the year. Weather is bleak, sunsets are early, resolutions are broken, and there’s only the vaguest glimpse of a holiday on the horizon. It’s perhaps this miserable context that is making the field seem extra productive, with a spate of new projects, toppings out and, completions announced this week.

15 Reasons why 2018 was a Record-Breaking Year for Tall Buildings

The CTBUH has released its Year in Review, charting the year’s tall building developments around the world. 2018 saw a record-breaking 18 supertall buildings (over 300 meters tall) built across the world, and 143 buildings of over 200 meters in height completed.

To quantify the extent to which architecture reached to the sky throughout the year, the CTBUH estimate that if each tall building completed in 2018 was laid end to end, it would exceed the entire length of the island of Manhattan; some 13 miles (21.6 kilometers).

The Council on Tall Buildings and Urban Habitat (CTBUH) has recently released a new research study titled "Tallest Demolished Buildings" that examines 100 of the tallest buildings ever to have been dismantled by their owners. The report confirms that, if JPMorgan Chase continues with their plans, SOM's 270 Park Avenue in New York City would become the tallest building ever conventionally demolished, as well as the first over 200 meters in height.

The study showed that in most cases, the buildings were torn down to make way for newer high-rises, as was the case for the current tallest building ever to be demolished, the Singer Building in New York City. The Singer Building stood 187 meters and 41 stories tall until it was torn down in 1968 to make way for One Liberty Plaza.

Ken Shuttleworth Talks with CTBUH About Make's Growing Office in Sydney

The 10 Tallest Uncompleted Skyscrapers

We all know a little about the world's tallest buildings—those engineering feats which define their cities and become symbols of human achievement—but what of the buildings that never took their planned place in their respective skylines? In 2014, The Council on Tall Buildings and Urban Habitat (CTBUH) released a report listing the 20 tallest buildings that were never completed (an up-to-date list is also maintained on their website here). In order to be considered "never completed," all of the buildings in the report had begun site work, but construction was completely halted with no reports indicating it will continue. Read on to find out the top 10 tallest uncompleted buildings in 2018 after the break.

2017 was another banner year for skyscraper construction.

According to the 2017 Tall Building Year in Review, the annual web report from The Council on Tall Buildings and Urban Habitat (CTBUH), a record-breaking 144 buildings 200 meters tall (656 feet tall) or higher were completed in 2017, led by the 599-meter-tall Ping An Finance Center and 555-meter-tall Lotte World Tower.

In the report, CTBUH outlines this year’s trends in tall building design. Notably, 2017 proved to be the most geographically diverse year in history for tall buildings, with 69 cities across 23 countries completing new towers, an significant increase from 54 cities and 18 countries in 2016. Of those numbers, 28 cities and 8 countries completed their new tallest building.

The 10 Different Ways to Measure a Skyscraper's Height

How do we determine the actual height of a building? Where do we place the dimension line? The history of measuring skyscrapers dates back to 1885, way before AutoCAD or Revit dimensions, when the Home Insurance Building in Chicago was among the first to boast of being the world's tallest building, but the Council on Tall Buildings and Urban Habitat (CTBUH)—or the Joint Committee on Tall Buildings, as it was originally called—wasn’t formed until 1969. Recognized by many as the foremost authority on tall buildings, the CTBUH is often cited in determining the world’s (or country’s or city’s) tallest building. However, the CTBUH is not the only organization with a stake in measuring buildings; the global building information database Emporis is also a major player. Between them, these two organizations provide 10 different ways to determine a skyscraper's height, which we have summarized below.

Seoul's Lotte World Tower Completes as World's 5th Tallest Building

KPF’s Lotte World Tower in Seoul, South Korea is officially complete, according to criteria established by the the Council on Tall Buildings and Urban Habitat (CTBUH). At 555 meters tall, the building becomes the tallest building in Korea (250 meters taller than the previous tallest building, Northeast Asia Trade Tower) and the world’s new 5th tallest building.

New Study to Investigate Skyscraper-Induced Depression and Motion Sicknesses

Have you been experiencing motion sickness, depression, sleepiness, and even fear, as you gaze out of your window from the 44th floor? If so, you may be prone to “Sick Building Syndrome” – the informal term for side effects caused by swaying skyscrapers, according to experts at the Universities of Bath and Exeter, who are launching a £7 million ($8.6 million) study into their causes and prevention through testing simulations.

“More and more people are living and working in high-rises and office blocks, but the true impact of vibrations on them is currently very poorly understood,” explained Alex Pavic, Professor of Vibration Engineering at the University of Exeter. “It will for the first time link structural motion, environmental conditions, and human body motion, psychology, and physiology in a fully controllable virtual environment.”
