China State Construction Engineering (Hong Kong) Limited

Sustainable Supply Chain

CSHK is committed to establishing a sustainable supply chain. We aim to ensure that all materials and products utilised in the construction process comply with Environmental protection standards, promote building sustainability.
We have prepared Procurement Policy and actively assessed our suppliers and sub-contractors, incorporating environmental and social responsibility factors into supplier selection, procurement processes and activities, with the ultimate goal of minimising the environmental impact of our supply chain.

Collaborating with Academic Institutions

Carbon Capture, Utilisation and Storage Technology – CCUS

CSHK has partnered with Zhejiang University, where the CCUS technology was developed, and CLEANCO₂, an industrialisation company, to utilise its carbon sequestration building material product – Carbon Fixing Brick - for the first time in an actual project.

CSHK hopes that this collaboration will leverage its strengths to actively promote carbon sequestration concrete building materials and technologies, providing a viable option for the development of low-carbon building materials in Hong Kong and Macau. Currently, carbon fixing bricks has been applied to the construction of some part of the fences in O · PARK2 to promote the embodied carbon reduction in building materials and the decarbonisation of buildings.

Pavement-Installed Solar Panel

While the use of solar energy has become increasingly prevalent, it still faces numerous limitations, especially the development of pavement-installed solar panel technology. In Hong Kong, the pavement-installed solar panel technology, have a unique opportunity for generating clean energy, however because of lacking local case studies, it is not widely adopted.

CSHK is committed to promoting innovative construction technologies. We have collaborated with the City University of Hong Kong and the Hong Kong Polytechnic University to initiate pilot applications of pavement-installed solar panels. This partnership enable us to evaluate the practical effectiveness of pavement solar panels.

BIM-integrated Carbon Assessment

CSHK collaborate with the professional building information modelling (BIM) team at the Hong Kong University of Science and Technology to integrate BIM with the Construction Industry Council’s Carbon Assessment Tool (CIC-CAT) which aimed to accurately forecast carbon emissions throughout the construction phase of a project.

Quality Management

CSHK and its major subsidiaries have obtained the international standard ISO9001:2015 quality management system certification. According to the ISO9001:2015 quality management requirements, we establish, implement and continuously improve the quality management system to ensure the users obtain the first-class project quality and improve their quality of life. Besides, we also formulated the "Project Engineering Quality Risk Assessment and Management Guidelines” for better quality management. Regular on-site inspections and assessments of the effectiveness of quality risk control measures are mandatory and take place monthly.

Quality risk assessment factors

Finished product risks

Intelligent Engineering Surveying Technology

By integrating of the Internet of Things, AI, cloud computing, BIM, and various other technologies, we are able to achieve real-time dynamic monitoring and analysis in different areas of the construction process. This enables the digitisation of measurements and facilitates more scientific and timely technical decisions to support the quality management of projects, ultimately increasing efficiency and productivity.

Tower Crane Mounted Camera Mapping and Monitoring System

Conventional measuring approach:

In typical construction site operations, levels are frequently utilised to measure the amount of concrete to be consumed. Nonetheless, the manual nature of these operations and the less precise devices often lead to deviations in the process. Consequently, this results in extra time and labour costs being incurred to repair or reconstruct the structure.

Tower Crane Mounted Camera Mapping and Monitoring System:

The tower crane’s arm is equipped with a camera that automatically captures high-resolution images of a specified area. The images are automatically stitched together for image overlay and comparison on cloud/local servers. The tower crane’s camera mapping technology has a tolerance of three millimetres or less to ensure structural accuracy.

Aerial Photogrammetry

Conventional measuring approach:

In manual measurement, additional manpower and time are needed, which hampers real-time remote monitoring of construction progress. Consequently, the efficiency of construction project quality management is compromised.

Aerial Photogrammetry:

The drone is capable of automatically capturing high definition images from various angles to facilitate 2D progress comparisons at different stages. These images are then utilised to create centimetre-level 4D models, integrating them with the actual scenario to achieve quantitative measurements of length, width, depth, and volume. To effectively track project progress, the drone can be deployed for multi-point 360-degree panoramic imaging, enabling interactive displays of project progress.
