Environmental Guidelines for Contractors

The University understands that the effort of contractors and sub-contractors are essential for maintaining a pollution-free campus. Therefore, Environmental Guidelines was prepared for the contractors to make them aware of the environmental requirements and the practicable measures to help them conduct the works in environmentally friendly ways.

Environmental Guidelines for Construction Sites

Air Pollution Control

  • The notifiable work should be carried out with prior notification to EPD.
  • Dusty Materials should be covered or sprayed with water.
  • Main haul road shall be paved and sprayed to suppress the dust.
  • On-going water spraying or dust enclosure should be applied during drilling or rock breaking.
  • The machines should be properly maintained to prevent black smoke emission.
  • Open burning is prohibited.

Water Pollution Control

  • Valid license should be applied from EPD if any effluent is discharged from site.
  • The discharge should comply with the discharge requirements and the records should be kept.
  • Bunds or U-channels should be built along site perimeter/within site area to direct effluent.
  • The wastewater treatment system should be properly maintained.

Noise Control

  • The work can only be carried out during restricted hours (means the time between 1900 V 0700 hours and any time on a general holiday, including Sunday) with valid Construction Noise Permit.
  • Valid Noise Emission Label is required for using a serial number of compressors or hand-held breakers (including pneumatic, hydraulic and electric).
  • The noise mitigation measures should be adopted such as barrier/enclosure, proper positioning of equipment, careful scheduling of work or adoption of quieter methods.
  • During operation, the engine covers of generators, air compressors and/or other powered mechanical equipment (PME) should be closed. If feasible, silenced model should be used.
  • Waste Management
    The construction and demolition wastes should be separated from general refuse and chemical wastes by on-site sorting. Timber, paper, metal and plastic should be collected for recycling.
  • The general refuse should be removed on a regular basis for hygiene.
  • The construction wastes should be collected and disposed properly by licensed collectors. The disposal records should be maintained to demonstrate wastes are properly disposed to landfill / public fill areas.
  • The site should be registered with EPD as a chemical waste producer if chemical wastes (e.g. spent lubricating oil or oil contaminated waste) produced on site. All chemical wastes should be removed from sites by licensed collectors and the records of trip tickets should be maintained.
  • Every container should be properly labelled with the English words and Chinese characters CHEMICAL WASTE and ƾǼo respectively; the chemical / common name(s); the particular risk(s); and safety precautions required in respect of the chemical waste.
  • The asbestos demolition works should be handled EPD registered professionals. The asbestos waste generated should be properly disposed and the relevant records should be maintained to demonstrate compliance.

Protection of Flora, Fauna and Historical Heritage

  • Dont damage any plant without permission.
  • Before cutting or transplanting the trees, the contractors should consult the specialists.
  • When any wild animal is found, stop works and do not disturb the animals before the arrival of specialists of Agriculture, Fisheries & Conservation Department.
  • If any historical heritage is found, stop works to minimise the damage and report to the relevant government department immediately.

Resources Conservation

  • Wastewater should be recycled from wheel washing for road spraying.
  • All taps are turned off when water is not required. All leaks in pipes are repaired once leaking pipes is observed.
  • Diesel-powered and electricity-powered plant and equipment should be shut off when they are idle.
  • The wood and bamboo should be properly handled and stored for reuse. If possible, the metal formwork and scaffold can be adopted to minimise the use of timber
