Renewable Energy
Waste Management
We strive to expand the electricity consumption from renewable sources and the use of renewable energy in project operations. • Solar PV system at headquarters office, site offices and site carpark shelters • Solar- and wind-powered lighting • Solar-powered equipment, such as CCTVs and flashing LED traffic lights
Our waste management approach is guided by the waste management hierarchy — prevent, reduce, reuse, recycle, recover and dispose, to minimise waste generation in our offices and project sites. We manage all hazardous and non-hazardous waste in compliance with statutory requirements. Licensed contractors collect and properly treat the waste through disposal or recycling. Most of our construction waste is inert and sent to government-run public fill reception facilities for reuse. Recycling facilities are set up at our headquarters, depot and project sites to collect and sort recyclables.
Prevent and Reduce
• Implement digital project management systems • Utilise BIM and off-site construction technologies to reduce material waste and on-site waste • Adopt Ground Penetrating Radar (GPR) for subsurface surveys and trenchless technologies for underground cable works to minimise excavation, soil removal and disposal, and material waste • Use reusable road markings for temporary traffic arrangements • Reuse excavated soil for backfilling • Reuse cable drums for underground cable works • Paper and cardboard, plastics, metal and rechargeable batteries • Electrical and electronic equipment • Toner cartridges • Barriers and water barriers • Uniforms and safety helmets • Organic waste, such as coffee grounds and yard waste
Water Management
Fresh Water
• Install dual-flush toilets and water saving taps to optimise water flow rates • Conduct regular inspections and maintenance of water pumps and pipes to prevent water leakages • Install sedimentation tanks at project sites to remove solid particles from wastewater before discharge • Reuse treated water for dust control and site cleaning
Solar PV Systems
Water is an essential, precious resource we rely on every day, while managing sewage is a challenge for all communities. We are committed to responsible water consumption and improving its efficiency. In addition, we ensure compliance with statutory requirements for treated wastewater discharge.
Headquarters Office
Reuse
In 2021, we installed 1,109 solar panels on the rooftop of our headquarters’ office building, creating a 423kW PV system. generates approximately 470,000 kWh of solar energy this year. We consumed about 185,000 kWh of generated solar energy, covering 21% of our headquarters' overall electricity consumption.
Wastewater
Recycle
Rainwater Harvesting for Solar-powered Evaporative Cooling System
Site Offices
Custom-made Portable Sedimentation Tank
Overhead Line Works Warehouse
As an example, the Public Lighting Project site office in Lai Chi Kok installed 84 solar panels in 2023, creating a 46.2kW PV system. It generates approximately 42,000 kWh of solar energy annually, reducing initial electricity consumption by approximately 18%.
A rainwater collection system is installed to capture and store rainwater. A solar PV system powers evaporative cooling equipment that uses the collected rainwater. Built mostly from recycled materials, this setup improves cooling efficiency, enhances workplace comfort, and reduces water and energy consumption.
Trenching Works
Our projects often involve trenching in open public areas, but space constraints make standard sedimentation tanks impractical. We developed a portable sedimentation tank for confined sites that one worker can operate and link with other tanks to enhance sedimentation performance.
