Case Study

Adopting modular integrated construction (MiC)

The Group has been developing prefabricated construction technology for over 20 years and is one of the leaders in the industry. In this year, it has diligently applied MiC to embrace the revolutionary future of the construction industry.

In recent years, the construction industry in Hong Kong has faced many challenges, including high construction costs, labour shortages, an ageing workforce, and increasing demands for quality, safety and environmental protection. The adoption of MiC technology can alleviate these difficulties by shifting most of the workflow from the construction site to the factory, with the following steps.

There are many advantages of MiC technology compared to tradition construction. This includes:

Because of the multiple advantages mentioned above, the Group believes that MiC technology is a major trend in the future construction industry and will drive the Group’s sustainability in terms of business operation, project quality, construction safety, environmental protection and carbon reduction. The Group’s subsidiary, China State Hailong Construction Technology Company Limited (“CS Hailong”), has six production bases for prefabricated buildings in Mainland China. The modules produced by the production base in Zhuhai have helped complete several epidemic prevention projects in Hong Kong within a very short construction period, among which the Temporary Quarantine Facilities at Lei Yue Mun was the first project in Hong Kong to use MiC.

The Group has been sparing no efforts to promote MiC technology. It has participated in video sharing meetings organised by the Architectural Services Department, seminars on transitional housing organised by the Transport and Housing Bureau, and consultation sessions organised by the Construction Industry Training Authority. In addition, a number of site visits have been arranged by the Group for industry professionals. From the delivery of relatively simple quarantine facilities to negative pressure wards in the hospital, the Group has successfully mastered the most advanced MiC technology and laid a solid foundation for its future business development.

Looking ahead, it is expected that MiC technology will help alleviate the tight supply and high cost of housing in Hong Kong. The Group will continue to promote the application of MiC and enhance the performance of sustainability. It is willing to work with all parties to fight the epidemic, build a better society and create a better life together.

Smart Construction Site Platform

The Group has established a smart construction site platform with increasingly mature and comprehensive technology for construction projects. The one-stop platform collects data from all aspects of the construction sites, including facial and license plate recognition at the entrance gates, wireless video surveillance, and environmental monitoring. It integrates information technologies such as spatial positioning, Internet of Things, big data, cloud computing, artificial intelligence and mobile devices to achieve real-time data integration and analysis, trend prediction and early warning for project overview, personnel management, construction progress, quality management and safety management. It also provides data support for project decision-making, proposes intelligent solutions to problems and imposes work efficiency.

  • With the use of Augmented Reality (“AR”) technology for mobile devices, the Group can display BIM models in detail at the construction sites, supporting various tasks such as inspection and acceptance of prefabricated components, problem identification and remediation of finishes, inspection of E&M installations and future maintenance.
  • At the same time, the Group’s use of virtual reality (“VR”) technology facilitates project design by allowing designers and engineers to connect to the same model in different locations. VR enables them to see real design effects in virtual space, discuss and make real-time changes, or compare multiple options.
  • The Group developed a real-time worker monitoring system, with sensors on the helmets. It uses Bluetooth technology to monitor and automatically record the distribution and duration of workers in various areas of the construction sites, helping to manage, analyse and deploy workers on-site and report on their performance. It was used to monitor the number of workers in each area of the construction site during the peak of the outbreak to avoid excessive gathering of workers and control the risk of infection. In case a worker is diagnosed, it can also help track his or her close contacts, isolate relevant personnel and identify key work areas for disinfection.

The Radio Frequency Identification (“RFID”) Technology

Due to the difficulty of identifying prefabricated components and MiC building components by appearance alone, it is necessary to adopt technological solutions to record component information and coordinate the work of different personnel in different geographic areas and times. RFID technology does not require direct contact or imaging, and can penetrate the coverings and the components themselves. It is easy to read and durable, making it suitable for component identification. The technology can be applied to the whole life cycle of component, from production, inspection, shipment, transportation to installation and consequently improve the management efficiency, making it an important technology for construction industrialisation.

Building Information Modeling (BIM)

At the “Celebration of BIM Achievement 2020” held by the Construction Industry Council, CSHK’s Related Case 4 APM and BHS Tunnel on Existing Airport Island, Tseung Kwan O Desalination Plant Stage I, and Relocation of Sha Tin Sewage Treatment Works to Caverns were recognised as “BIM Projects 2020”. The Group’s innovative contribution and achievements in the adoption of building information modelling were recognised by the industry when it took up three out of the ten BIM Projects.

In addition, CSC Macau won the tender for the Construction of the Main Structures of the Cotai Healthcare Complex (the “Cotai Hospital”). With the decision of adopting high technology such as BIM to overcome the difficulties of the project, deepen the design and guide the construction, CSC Macau quickly set up a professional team to establish and integrate relevant architectural, structural and electromechanical models. Through 3D modelling, all parties involved in the project can have a more intuitive and profound understanding of the design intent and construction difficulties, and detect design problems and collision conflicts at an early stage, thus improving the quality of the project. BIM enables multi-disciplinary online collaborative design and operation, reducing file transfer and improving design efficiency. It can also simulate the construction schedule and approach to help arrange and optimise the construction plan. By breaking through paperbased technical briefings, BIM improves communication and construction management efficiency with 3D visualisation. The effective application of BIM technology in the Cotai Hospital has been recognised by the industry and received the Grand Award (Offshore Category) at the Hong Kong Institute of Building Information Modelling Award 2020.
