|The Hong Kong Regional Group will be holding a technical meeting on 'Precast to Modular Construction' by Dr Goman Ho.
Great Egyptian pyramid of Giza is one of the oldest prefabrication structures which still exists. It was make by stones being cut before they are placed in their designated location. With this approach, Tower of Babel would be the first prefabricated tall building since civilization begins in more than 5000 years ago. With the invention of reinforced concrete and structural steel, precast members in various form are also available. With the increase in tower crane capacity and development of tall buildings, modular and PPVC construction skills were developed.
In Hong Kong, most developments consist of prefabrication elements. They could be prefabrication pods, staircases and façade etc. With the increase in demand of housing, the cost of material is becoming less important while the speed of construction becomes one of the key concern plus high labor cost. Because of this, DfMA, modular and PPVC construction technology has developed.
This lecture will briefly review the historical development of precast, prefabrication construction as well as the current technology of modular/PPVC construction. Project examples such as 32-story high modular building will be used to demonstrate capability of modular construction method.
Dr Goman Ho is an Arup Fellow and has been working with Arup since 1992. He was the first global leader for Arup Tall Buildings Skills Network and also serve as the regional Seismic Skills Network. He was involved as PD/PM/PE for a number of tall building projects with an accumulated height approaching to 8 km including CCTV HQs in Beijing, the 460m Vincom Landmark 81 Tower in Ho Chi Minh City, the 528m tall Z15 in Beijing, the 597m tall Goldin Finance TJ117 in Tianjin and currently working on a 650m tower in Wuhan. He is also strong in academic and research. He has published more than 30 technical papers in International Journal Papers and Conferences.
