Off-Site Construction


Modular Integrated Construction (MiC)

Chun Wo has always remained at the forefront of the latest trends in construction. By adopting innovative MiC* technology, a state-of-the-art construction method, we can intensively speed up the operations of our projects, increases construction productivity, safety, and sustainability.

Chun Wo’s Concrete MiC System

Chun Wo and the P&T Group (P&T) have worked together to develop a 5-face “Concrete MiC System” and an advanced “wall connection technology” that is applicable to our Concrete MiC System. The entire Concrete MiC solution and the wall connection technology have received “In-principle Acceptance” from the Buildings Department, meaning that they can be applied in building development projects in Hong Kong.

The “wall connection technology” of Concrete MiC has also obtained the pertinent patent, making Chun Wo the first Hong Kong construction company to use this method in the design and construction of buildings up to 40 stories high, hence substantially helping enhance construction efficiency.

Possessing extensive experience and a team of experienced BIM professionals, Chun Wo is capable of providing one-stop solutions from design to construction in the field, successfully applying the Concrete MiC Systems to different projects.

MiC Brochure
*MiC –Modular Integrated Construction is building method based on the concept of “factory assembly followed by on-site installation”. Free-standing integrated modules (completed with finishes, fixtures and fittings) are prefabricated in a factory before the installation on-site to complete the construction of a building.


DfMA is an indispensable part of MiC. It is a design approach which focuses on greater ease of manufacturing and efficiency in assembly. In recent years, the construction industry of Hong Kong has begun to adopt DfMA for off-site pre-fabrication of MiC modular flats and components, such as kitchen and toilet modules. By simplifying the design, it is possible to manufacture and assemble various modules and components more efficiently.

Revamp of public toilets at Terminal Building, Hong Kong International Airport

By employing a DfMA approach, Chun Wo finished the revamp of public toilets at Terminal Building at the Hong Kong International Airport. The improvement works include renovation of public toilets at different locations within the terminal buildings (Terminal 1 and Limousine Building). Pre-scribed components in these toilets are prefabricated off-site using the DfMA approach, which hugely minimized the interference of construction on the operation of the Airport and to the public.

Greenhill Villa

The Greenhill Villa is the first precast concrete building in Hong Kong comprising three tower blocks of 36, 34 and 32-storeys, a podium and two lower ground floors. With early implementation of BIM technology the team identified and avoided clashes to reduce wastage of materials and mitigate the risk of external wall tiles spalling.  Prefabricated components included structural and non-structural external walls, stairs, refuse chutes, partition walls, parapet walls, semi-prefabricated floor slabs and balconies.
