  1. Construction Noise Control« Noise Control Ordinance »(Chapter 400)

  2. Form 4 Noise Control Ordinance (Chapter 400) Construction Noise Permit Application Content • «Noise Control Ordinance» • Product noise control • Construction noise control • Construction noise permit application • Enforcement practices

  3. Neighbourhood noise • Industrial / commercial noise • Product noise control • Construction noise «Noise Control Ordinance» • Neighbourhood noise • Industrial / commercial noise

  4. Product Noise Control • To phase out noisy products

  5. ‘Prescribed’ products for control: • Air compressors • Hand held breakers • is required for their use Product Noise Control • To phase out noisy products Green Label

  6. Construction Noise Control • Percussive Piling • General Works

  7. The Construction Noise Permit (CNP) System

  8. Percussive Piling Control • 0700-1900 hours on non-holidays • CNP Required • Banned during other times

  9. Percussive Piling CNP «Technical Memorandum for CNP assessment» • Refuse or issue CNP for 3, 5 or 12-hour • Piling hours to suit schools & exams

  10. Percussive Piling CNP • Tightened controls on noisy hammers (e.g. : Diesel piling hammer) • CNP for noisy hammers would be refused (Provision for special cases)

  11. PME (Powered Mechanical Equipment) • General control for the whole territory SPME (Specified Powered Mechanical Equipment) PCW (Prescribed Construction Work) • Stricter requirement within designated areas (e.g. major housing estates) General Works

  12. Specified Powered Mechanical Equipment General Works • Hand-held percussive breaker • Bulldozer

  13. Specified Powered Mechanical Equipment General Works • Concrete lorry mixer • Dump truck • Vibratory poker

  14. Prescribed Construction Work (PCW) General Works • Erection / dismantling of formwork / scaffolding • Loading / unloading / handling of rubble, wooden boards, steel bars wood or scaffolding material • Hammering

  15. Quiet Method of Prescribed Construction Work General Works • Disposal of rubble through plastic chutes

  16. CNP Assessment Technical memoranda for assessment General Works • Assess noise impact on nearby Noise Sensitive Receivers • Correction for multi- sites • Complaints / legal actions are taken into consideration

  17. Construction Noise Control Philosophy • Daytime - no CNP control on GW • Nighttime - people have the right of peace for rest • No CNP granted unless really necessary

  18. CNP Applications • Fully utilize the less noise sensitive hours • Apply only if really necessary • Self - assess before applying • Apply well in advance • Provide relevant information

  19. CNP Assessment • Meeting noise requirements • No prohibited activities • Unavoidable constraints on working hours • Justification required • Quietest means + Practical noise mitigation measures

  20. Quiet Construction Work • Use Quieter Equipment Modern wire saw for concrete cutting 16 dB(A) lower than excavator mounted breaker

  21. Hydraulic piling hammerreduce 2-9 dB(A) Hydraulic crusher for demolition 20 dB(A) lower than excavator mounted breaker Quiet Construction Work • Use Quieter Equipment

  22. Enclosure effectively reduced noise from generator Acoustic enclosure for breaker reduce 3-5 dB(A) 6m barrier for pre-bored machines reduce 3 dB(A) Quiet Construction Work • Use Quieter Equipment • Enclosure / Barriers

  23. Specific design noise enclosure Container used as noise enclosure Quiet Construction Work • Use QuieterEquipment • Enclosure / Barriers

  24. Good communication with affected neighbors reduce complaint Control of the flow of people during holiday Communication with Neighbours

  25. Enforcement Practices • EPD / Police will take action if : • use of prescribed products without the • no valid CNP for work when necessary • CNP conditions are not complied with Green Label

  26. Enforcement Practices • Police would: • possess copies of issued CNP • investigate complaints • initiate prosecution

  27. Enforcement Practices • EPD would : • relay complaints to Police • investigate complaints • conduct surveillance inspection • initiate prosecution

  28. Enforcement Practices • Offences spotted would : • result in cancellation of CNPs • have an effect on CNP renewals • lead to prosecution action

  29. Enforcement Practices • Main contractors are strictly liable • Any persons involved are also liable: • sub-contractors • person-in-charge • workers • managing directors

  30. Enforcement Practices • Fine : • $100,000 on first conviction • $200,000 on 2nd or subsequent convictions • daily fine $20,000 per day. • Conviction records would be : • Relayed to Client Government Departments / bureaux • Released to the press

  31. Summary • Noise Control Ordinance • CNP for -Percussive Piling -General Works • Green Label for -Air compressors -Hand-held breaker Green Label

  32. Summary • Allow no work at night time & on holidays without a CNP • Monitoring / control site activities - own work / subcontractors • Rectify irregularities promptly • Educate staff / provide training • Minimize disturbances • Prevention is better than cure
