China to construct 300ha special economic zone in Bangladesh
The project to create a special economic zone was mooted in 2014, during a visit to Beijing by the Bangladeshi prime minister Sheikh Hasina. At this time the proposed contractor for the zone was identified as China Harbour Engineering Company, and the level of investment was set at $100mn. However, the scheme quickly stalled.
Plans have been resurrected this month, initiated by China Harbour, which has reiterated its commitment to investing £100mn in Chattogram. The newspaper The Daily Star in Bangladesh reports that over 60 Chinese companies are interested in participating in the Chinese Economic and Industrial Zone, and have jointly pledged over $280mn.
A representative of CEIZ, Jiang Wei, commented that construction would be contracted to China Harbour, and that it was ready to start work. He said: “We will focus on four sectors for investment in the zone – logistics, manufacturing, chemical and readymade garments.”
Wei also commented on the potential scale of the special economic zone: “CEIZ will be able to eventually attract more than $1bn in foreign investment, create 60,000 to 90,000 jobs, directly or indirectly, and ultimately boost industrialisation and develop the economy of the surrounding Chattogram district.”
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.
