Construction of Singapore Changi Airport’s Jewel is 75% complete

The ‘Jewel’ complex being constructed at the Changi Airport in Singapore is 75% complete, and on schedule to be open in 2019.
The Jewel façade is being constructed using more than 9,000 pieces of glass – each one specially manufactured.
The façade will also feature more than 18,000 pieces of steel beams and over 6,000 steel nodes.
Due to the complexity of the façade, with each piece of custom made glass having different dimensions, the project has been in development for five years.
“Given the unique measurements of each glass panel, the installation process warrants precise coordination to ensure that each panel is fitted into the correct ‘grid’ placement that it is planned for,” stated Jewel Changi Airport.
“Meticulous execution is also required as the glass panels are transported from the ground level to the top of the façade for the roof installation.”
It will weigh more than 6,000 tonnes and will connect the Arrival Hall in Terminal 1 to Terminals 2 and 3 through pedestrian bridges.
The construction project will feature a 40m waterfall and a five-storey plant collection, dubbed the Rain Vortex and Forest Valley.
In total, the complex will span 10 storeys and cover 134,000sqm, housing 9,000sqm of retail space and 300 tenants.
China’s Broad Group builds 10-storey apartment in 28 hours
The China-based manufacturing enterprise Broad Group has managed to construct a 10-storey steel apartment building in just over a day. Constructed in the city of Changsha in China, the company used bolt-together modular units known as its “Living Building System”.

Broad Group, a manufacturing company based in Changsha, constructs a range of air-conditioning, heating, and prefabricated structural units. It accomplished the challenge in 28 hours and 45 minutes, enlisting help from three cranes and an on-site workforce.
Broad Group’s “Living Building” system
Designed to be easy to transport and install, Broad Group’s “Living Building” system uses components that are able to fit into a standard shipping container, and then be bolted together when they reach the site. Ductwork and wiring are fitted directly by the factory, the company said.
As part of the system, Broad Group’s B-Core steel slabs are used as structural elements which, the company claims are 10-times lighter and 100-times stronger than conventional slabs. The company also says they have the ability to resist earthquakes and typhoons, and that it costs less than a carbon steel building and has low energy consumption.
Broad Group also says that buildings of up to 200 storeys, supertall towers, could be built using the same modules due to the B-Core steel slabs’ strength and lightness.
Other Broad Group projects
Broad Group has completed other significant projects in the past. In 2012, for instance, it attempted to build the tallest tower in the world in Changsha at 838m, which would have made it 10m taller than the Burj Khalifa in Dubai. The company claimed it could have made the building, named Sky City, in just eight months. However, due to not receiving approval, it was never built.
In 2015, the company accomplished another “speed-build” challenge, constructing a 57-story tower using the “Living Building system”. It was completed in just 19 days.
