ABM expands range of pre-stressed concrete beams
Investment at ABM Europe’s Nottinghamshire, UK, facility is permitting production of an increased range of larger and heavier bridge components, allowing the company to manufacture U and W-shape pre-stressed concrete bridge beams of up to 120 tonnes alongside their existing range of products. This additional capability will allow ABM to offer customers shorter cycle times – regardless of the weight and complexity of the beam – and products of high and consistent quality.
The new development follows a careful examination of some of the leading beam casting facilities in Europe in order to create an adaptable process that not only offers efficient and rapid production, but that can be quickly changed to produce different types of beams.
The new plant is 64 metres long which, with the facility’s increased 120 tonnes lift capacity, gives ABM the capability to produce the largest bridge beams in the UK or multiples of smaller units. According to Business Developer Manager Mike Sanderson: “No other pre-cast concrete manufacturer on the UK mainland has the capacity for these large beams, this flexibility, and such an extensive product range”.
First castings with the new facilities began in June 2015, and the first W shape section beams were cast in January 2016.
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.
