57 Storeys & Built in 19 Days – Modular's New Innovation 57 storeys & built in 19 days – modular’s new innovation BROAD Group has once again taken modular construction to new heights and in record time. First it was the T30 Hotel in 2012, a 30-storey building constructed in 15 days, and now a 57- storey building erected in 19 days. But what were some of the key considerations this time round that allowed BROAD Group to improve the process? The company has a truly vested interest in modular innovation, which is exciting for the direction of modular construction on a wider scale. J57, courtesy of BROAD Group Ahead of Modular Construction & Prefabrication 2015, we spoke to Juliet Jiang, VP of BROAD Group, to find out how modular construction influenced the design scope of the project, and where sustainability played an important role. With 19 atriums (each at 10 metres’ height), 800 apartments and office space that can accommodate 4,000 people, J57 is in fact a mini prototype for the 220-storey Sky City. “By using modular construction, we were able to reduce the use of concrete by 15,000 trucks. This was very important not only to save on materials, but minimise the environmental impact. Dust levels during construction were almost non-existent compared to traditional methods,” Ms Jiang says. From a sustainability and design perspective, the building is five times more energy efficient than its conventional counterparts. J57 features 20-cm thermal insulation for walls; four-paned super white glass windows; 100 per cent filtered fresh air 24/7; and a combined cooling, heating and power system that makes the building extremely energy efficient. www.modularconstructionaustralia.com.au Call + 61 (2) 9229 1000 Email: [email protected] Additionally, the air conditioning machine room is located in the basement of the building – air conditioning operating costs are next to nothing because of the waste heat. All the above- mentioned items have contributed to 12,000 tonnes of CO2 cutting compared to other same- sized buildings. This equates to 660,000 tree plantings and 46 tonnes of air pollutant reduction, which makes the building free from ‘sick building syndrome’. BSB & modular prefabrication BROAD Group’s subsidiary company Broad Sustainable Building (BSB) is the enabler behind the success of modular construction for J57. One of the biggest factors in this formula has been quality control of the module prefab process in a factory environment. Production environment, courtesy of BROAD Group This approach has paved the way for teams to control cost more thoroughly, eliminate construction material waste, prevent industry budget traps and operate against quick funding turnovers. “BSB technology is an exciting part of our modular construction investment. The building costs can reach up to 30 per cent in savings, while also dramatically improving the construction quality. BSB involves standardised design, modular production, stringent product management and highly-skilled workers. And at the end of the day, only one company is responsible for all quality assurances,” Ms Jiang notes. Underpinning the manufacture and construction strategy is an essential commitment to sustainability and longer life spans – part and parcel with BSB’s performance criteria. www.modularconstructionaustralia.com.au Call + 61 (2) 9229 1000 Email: [email protected] For example, cold galvanising anti-corrosion technology is applied to steel materials, while tight thermal insulation prevents condensation corrosion. The duration of each treatment extends to 50 years. Additionally, all steel materials can be re-used post decommissioning. BSB workshop, courtesy of BROAD Group This dual focus reflects an exciting trend that more companies are pursuing – using modular construction to balance cost and performance against sustainability. BROAD Group used ‘3rd generation technology’ to construct J57, which is an important precursor to the planned 220-storey Sky City (J220) that will involve ‘4th generation technology’. Modular construction is progressing through leaps and bounds, with new capabilities coming through from both a technology and process perspective. At Modular Construction & Prefabrication 2015, Juliet Jiang will present an exclusive case study on J57, examining in particular the use of modular prefabrication to increase the rate of construction, reduce capital and operating costs, and minimise the environmental impact. She will be joined by specialist for companies including Laing O’Rourke, AECOM, Mirvac Design, and Wood & Grieve Engineers among others.

  • Modular Buildings in Modern Construction
    Available online at www.sciencedirect.com ScienceDirect Procedia Engineering 153 ( 2016 ) 167 – 172 XXV Polish – Russian – Slovak Seminar “Theoretical Foundation of Civil Engineering” Modular buildings in modern construction Elena M. Generalovaa*, Viktor P. Generalova, Anna A. Kuznetsovaa a Samara State University of Architecture and Civil Engineering, Molodogvardeyskaya St 194, Samara, 443001, Russia Abstract The article considers temporary methods of using modular units in construction. The advanced world experience in the construction of modular buildings is analyzed. It is emphasized that modular construction has the potential to shorten project design and engineering time, reduce costs and improve construction productivity. The installation of modular buildings is cost- efficient, safe and eco-friendly. Modern modular systems are based on using not only large elements such as «block rooms» but various small 3D building elements. The analysis result of Russian developments in the construction of modular buildings proves that Russia has great experience in the development of 3D reinforced concrete modules. As the research results the article shows promise for developing of modern modular construction systems in order to provide the population with affordable, comfortable and eco-friendly housing. The paper describes the prospects and relevance of introducing modular prefabricated units not only into low-rise but into multi-storey and high-rise construction as well. ©© 2016 2016 The The Authors.
