The year 2019 marked a historic milestone in vertical construction. According to the Council on Tall Buildings and Urban Habitat (CTBUH), 26 supertall buildings measuring 300 meters or more were completed worldwide, shattering the previous record of 18 set just one year earlier. This surge in supertall construction reflects broader trends in urbanization, land scarcity, and advances in structural engineering that allow builders to reach unprecedented heights. For construction professionals seeking to understand the building science behind these achievements, lessons from the tallest projects directly inform how we approach everything from foundation design to the selection of weather-resistive barriers and building envelope performance at every scale of construction.
The 2019 Super Building Boom: Global Data and Regional Trends
The CTBUH report revealed that 126 buildings of 200 meters or taller were completed in 2019. While this represented a 13.7 percent decline from the 146 completions in 2018, the record-breaking number of supertall completions demonstrated that the industry continues pushing the boundaries of what is structurally possible. The global inventory of supertall buildings now stands at 170, compared to just 26 in the year 2000, reflecting a six-fold increase in less than two decades. This rapid growth has significant implications for seismic upgrades and building rehabilitation strategies, as older structures must be re-evaluated against the performance standards set by newer, taller neighbors.
China dominated the supertall landscape, accounting for 14 of the 26 supertall completions. The country also led in the 200-meter-plus category with 57 buildings, though this represented a notable drop from the 92 tall buildings completed in China during 2018. This shift suggests a maturation in China construction market, with developers moving from quantity toward quality and height as primary differentiators.
- Total 200m+ buildings completed globally in 2019: 126
- China: 57 completions (down from 92 in 2018)
- United States: 14 completions (up from 13 in 2018)
- Middle East: 11 completions (down from 13 in 2018)
- United Arab Emirates accounted for 9 of the 11 Middle Eastern completions
Engineering Achievements Behind the Top Supertall Structures
The ten tallest buildings completed in 2019 represented a remarkable cross-section of global engineering talent. The Tianjin CTF Finance Centre in China topped the list at 1,739 feet, followed by the Lakhta Center in St. Petersburg at 1,516 feet and the Suzhou IFS at 1,476 feet. Each of these structures required solutions to unique site conditions, wind loads, and foundation challenges. For instance, the Lakhta Center became the tallest building in Europe and had to overcome the challenges of construction on soft soils near the Gulf of Finland, requiring a foundation system of 264 piles driven to depths of over 80 meters. As noted in industry coverage on the worlds fourth tallest building completed in China, the Exchange 106 in Kuala Lumpur reached 1,460 feet and demonstrated how Southeast Asian markets are competing in the supertall arena through innovative structural solutions.

New York City contributed 30 Hudson Yards as the only United States supertall completed in 2019, though the city accounted for 8 of the 14 American tall buildings over 200 meters. The remaining US completions included three in Miami and one each in Chicago, Boston, and Austin. The 30 Hudson Yards project was particularly notable for its construction over active rail yards, requiring a massive platform structure to distribute building loads to foundations located between and around active train tracks.
Construction Methods and Material Innovations in Supertall Building
The methods used to construct supertall buildings in 2019 offer valuable insights for construction teams working at any height. High-strength concrete mixes, advanced formwork systems, and rigorous quality control protocols were essential across these projects. The Tianjin CTF Finance Centre relied on high-performance concrete with compressive strengths exceeding 100 MPa, delivered using specialized pumping systems capable of moving material vertically over 500 meters. The Lakhta Center in St. Petersburg had to contend with freezing temperatures during its winter construction phases, requiring heated formwork and accelerated curing compounds. These extreme conditions required specialized cold-weather concreting techniques that share principles with what builders can learn from the worlds tallest Passivhaus building, particularly in the areas of thermal performance and envelope tightness.
Wind engineering played a critical role in the design of each supertall structure. Dampers, tuned mass dampers, and aerodynamic shaping were employed to mitigate sway and ensure occupant comfort. The Wuhan Center Tower featured a distinctive tapering form that reduced wind loads by more than 20 percent compared to a rectangular alternative. The Suzhou IFS incorporated a 500-ton tuned mass damper near its upper floors to counteract vortex shedding effects common in tall, slender towers. These wind engineering solutions are essential for maintaining structural integrity and occupant comfort in the highest occupied floors.
- High-strength concrete with compressive strengths exceeding 100 MPa
- Tuned mass dampers for wind-induced motion control
- Aerodynamic facade shaping to reduce wind loads
- Advanced formwork systems for rapid vertical construction
- Cold-weather construction protocols for northern climates
- Deep pile foundation systems extending over 80 meters below grade
Regional Construction Practices Across Continents
The geographic distribution of 2019 tall building completions reveals distinct regional construction practices. China continued to dominate with 57 completions, though the slowdown from 92 in 2018 suggests a market correction rather than a structural decline. Many Chinese supertall projects are concentrated in special economic zones and rapidly urbanizing inland cities such as Wuhan, Chongqing, and Nanjing. These cities have invested heavily in transit-oriented development that clusters high-density residential and commercial towers around public transportation hubs. The Raffles City Chongqing complex, for example, includes a sky bridge connecting its multiple towers at 250 meters above ground, a remarkable structural achievement in its own right.
The United States recorded 14 tall building completions in 2019, up from 13 the previous year. New York City alone accounted for 8 of these, with the remaining completions distributed across Miami, Chicago, Boston, and Austin. Notably, New York was the only US city to complete supertall buildings, delivering four in total, including the 30 Hudson Yards structure built on a platform over active rail infrastructure. These projects demonstrate how building envelope best practices and weatherstripping techniques must adapt to the extreme wind pressures and temperature differentials experienced at upper floors, where facade systems face substantially greater environmental loads than at ground level.
The Middle East contributed 11 completions, down from 13 in 2018. The United Arab Emirates led the region with 9 tall buildings, reflecting Dubai and Abu Dhabi continued investment in landmark towers despite regional economic headwinds. The 13.7 percent decline in global completions compared to 2018 was primarily driven by China reduction from 92 to 57 buildings, suggesting that other markets remained relatively stable or showed modest growth. South Korea contributed the LCT The Sharp Landmark Tower in Busan, demonstrating that East Asian markets beyond China remain active in the tall building sector.
Building Science Lessons for Future Skyscraper Projects
The engineering data from 2019 supertall completions provides actionable lessons for construction teams planning projects of any height. Foundation design for supertall buildings requires deep pile systems often extending more than 50 meters below grade, with rigorous load testing protocols that validate bearing capacity before superstructure construction begins. Core-wall construction using slip-form or jump-form techniques allows vertical progress rates of one floor every three to four days, a rhythm that can inform scheduling and resource allocation even on mid-rise projects. The use of Building Information Modeling (BIM) was standard across nearly all supertall projects completed in 2019, enabling coordination between structural, mechanical, and facade trades at a level of detail impossible with traditional 2D drawings. The building science symposium discussions on modern construction highlight how these same principles of thermal bridging control, air barrier continuity, and moisture management apply whether a building rises 30 stories or 130 stories.
Wind tunnel testing remains a non-negotiable step for any building exceeding 200 meters in height. The data collected from these tests influences structural member sizing, cladding design, and occupant comfort criteria. For the 30 Hudson Yards project in New York, wind tunnel studies informed the placement of notches and setbacks that reduced vortex-induced vibrations and cut steel tonnage by approximately 15 percent compared to initial designs. These same types of studies are becoming more accessible for mid-rise projects as computational fluid dynamics tools become more affordable and widely available for mainstream construction applications.
Looking Ahead: Projections and Lessons for the Construction Industry
The CTBUH projected that between 115 and 145 buildings of 200 meters or taller would be completed in 2020, a slight downward revision from its 2019 projection of 120 to 150. New York City alone expected 10 tall building completions in 2020, highlighted by the 1,550-foot Central Park Tower and the 1,428-foot 111 West 5th Street building. These projections underscored the continued demand for vertical construction, even as overall completion numbers appeared to stabilize after years of aggressive growth. The lessons drawn from the 2019 cohort will shape how the next generation of tall buildings is designed, engineered, and delivered across global markets.
Ultimately, the record-breaking year for supertall completions in 2019 demonstrated that the global construction industry has the technical capability to build higher than ever before. However, delivering projects at this scale requires deep expertise in structural engineering, building science, and project management. For construction firms looking to build teams capable of tackling these complex projects, developing a structured interview process for home building leadership hires ensures the right expertise is in place from the outset. The technical achievements of 2019 will inform construction practices for years to come, raising the bar for what the industry can accomplish at every height scale.
