Development of HKU Hostel at High West Site to Optimise MiC Innovations

A mixed development by the University of Hong Kong (HKU) at High West Site, comprising student hostels of 19 to 20 storeys as well as staff quarters, will incorporate multiple innovations of the Modular Integrated Construction (MiC) method—covering ‘horizontal divisions’ technique; prefabricated modular balcony; and double-wall design—to enable the quality of its interior and exterior to be on a par with most large-size residential units in the private sector.

The four-building project is set to provide over 1,000 units. To this end, horizontally divided MiC units will be utilised in place of vertically divided ones, as such arrangement can largely reduce the number of joints between modules; allow for fewer modules to be used; increase indoor space; and mitigate the risk of water infiltration from external walls. The modules will be connected by welded steel plates, making it part of the main structural framework to minimise building deflection under strong wind.

Featuring the first prefabricated modular balcony approved by the Buildings Department, components of the balconies such as railings, floor tiles and waterproof layers will be installed, tested and calibrated in advance. Similarly, the installation and testing of all windows will be done in the factory, which provides better quality control than conventional on-site installation.

Adopting a double-wall design for kitchens and bathrooms, other areas will be single-walled to create usable floor areas comparable to that produced by wall thickness of traditional construction methods. Together with high ceilings reaching 2,970 millimetres, which overcome previous transportation and assembly limitations, the dimensions will create spacious spaces for comfort. Meanwhile, the double-wall design serves to facilitate the completion of waterproofing, cabinetry and internal finishing in the factory. —Construction+ Online
