C-SMART Site Integrated Management System

Independently developed by CSHK, C-SMART employs Internet of Things, cloud analytics, AI and other technologies to collect, aggregate and analyse site data to comprehensively manage and supervise all aspects of construction projects, thereby enhancing the efficiency of construction management and quality control. C-SMART’s Material Management and Environment and Energy Consumption Management modules enable us to understand and monitor the environmental performance of our sites, effectively managing the supply and use of materials and resources in order to reduce waste and pollutants. At the same time, the modules help us monitor and manage the energy consumption of our sites to find the best solutions to minimise energy waste. C-SMART has been used in 40 construction sites in Hong Kong.

BIM Application

CSHK actively applies BIM technologies to major projects in order to improve construction efficiency and quality. This enables better management and utilisation of resources during design and construction, thereby reducing environmental impact. In addition, BIM technologies improve the energy efficiency of buildings by analysing the energy consumption of built assets and generate energy assessment reports at the early stage of design. This ensures accurate energy consumption estimations throughout the lifecycle of the built assets, so that the best energy strategy can be defined to minimise waste and energy costs.

BIM Application

Industrialisation of the Construction Industry

We have made active efforts to advance the industrialisation of the construction industry in Hong Kong to improve productivity, construction efficiency and project performance. We have adopted the following modern construction methods. For example:

Design for Manufacture and Assembly (DfMA)

Improve product ease of manufacturing and assembly without compromising functionality, appearance and reliability. Design components that are easy to manufacture and assemble to reduce on-site operations and waste

Multi-trade Integrated Mechanical, Electrical and Plumbing (MiMEP)

Integrate and embed electrical and mechanical equipment into modular components and have them manufactured in the factory

Modular Integrated Construction (MiC)

Move on-site operations to standardised factories that manufacture “ready-for- assembly” components, in order to control the quality of the production process

These methods use prefabricated components to reduce the time and materials required for on-site fabrication and installation, delivering low-cost, high-speed, high-quality construction.

Improvement in

+ Construction quality

+ Work environment

+ Construction efficiency

+ Construction safety

Reduction in

– Construction personnel

– Environmental pollution

– Site accidents

Smart Building Solutions:
Community Treatment Facilities

CSHK has successfully implemented the innovative construction model of “BIM+MiC+MiMEP” and smart logistics management system in the eight Community Treatment Facilities, and utilised all C-SMART functions to reduce the construction schedule by 60%. This model has enabled CSHK to deliver eight Community Treatment Facilities aided by the Central Government of China within four months, providing a total of about 40,000 beds. In particular, it took the construction team only seven days to complete the nearly 60,000 square metre facility in Tsing Yi. The successful application of this innovative model has played a positive role in Hong Kong’s fight against COVID-19.

Responding to Climate Change

CSHK has been strengthening carbon reduction in all aspects, including project design, building material selection, construction, operation and maintenance.

Site Electrification

Based on in-depth studies and analysis, we realised that construction sites generate massive carbon emissions that, in the long term, will exacerbate the climate change crisis. We have therefore spared no effort in promoting site electrification to create a green and sustainable future. We have also invested significant resources to enable grid connection as soon as possible or set up temporary transformer rooms to supply electricity. At the same time, we have introduced the latest Enertainer technology to replace traditional diesel generators, reducing carbon emissions at source and minimising air and noise pollution.

As of the end of 2022, we have introduced Enertainers to
8 sites, and have
136 electric machinery.

Utilise Renewable Energy

We actively embrace renewable energy in our construction projects to improve energy efficiency and minimise environmental impact. In addition to meeting part of our electricity needs and reducing fossil fuel consumption, renewable energy helps control greenhouse gas emissions and supports our environmental goals. We seek to install solar panels in suitable locations on larger sites, such as rooftops of office buildings, car parks, entrance checkpoints, etc., to provide electricity for on-site use.

In 2022, 47 Mwh of renewable energy was generated on our construction sites.

Resources Management

Waste Management

During the construction process, a large amount of construction waste is generated. Effective resource management can minimise waste generation and reduce operating costs.

Resources Management

Matching supply and demand of different materials on sites to reduce procurement
Adopt C-SYS⁺ system to help manage and analyse resources usage
Save materials by 25% with the adoption of DfMA method
Reduce timber consumption by 80% with the application of MiC technologies

Reducing Waste Disposal

Install food waste treatment equipment on sites
Transport yard waste to Y．Park or furniture factories for upcycling
Place waste sorting bins on sites
Reduce concrete and rebar consumption
Reduce construction wastes by 70% with the application of MiC technologies

Waste Recycling

Ground surplus fill material is used for backfill in other sites
Install site crushers to process rock materials for concrete production
Rebar management

Water Management

We acknowledge the importance of water resources to the construction industry and are committed to minimising water wastage in the construction process. To enhance water efficiency, we have installed water storage tanks to harvest rainwater for reuse. In addition, water tanks are installed at the project's waste water treatment facilities outlets to collect treated effluent for dust suppression on site to minimise the consumption of water resources.
