1 Introduction
1.1 Background
1.1.1 In August 2002 BMT Asia Pacific Limited (BMT) was awarded the contract for Agreement No. CE 18/2002: Environmental Impact Assessment Study for Construction of Helipads at Peng Chau and Lamma Island / Investigation by the Civil Engineering Office, Civil Engineering & Development Department (CEDD). Two separate Environmental Impact Assessment (EIA) studies have been carried out for the proposed helipads at Peng Chau and Yung Shue Wan, Lamma Island.
1.1.2 In accordance with the EIA Study Brief, this Environmental Monitoring and Audit (EM&A) Manual has been prepared by the EIA Study Team. The EM&A Manual specifies the recommended environmental monitoring and audit requirements, where theses are considered necessary, for the concerned environmental aspects to ensure effective implementation of the environmental protection and pollution control measures.
1.1.3 This Manual provides systematic procedures for carrying out recommended monitoring and audit works for checking potential environmental impacts that may arise from the construction of the helipad at Yung Shue Wan, Lamma Island. Mitigation measures recommended in the EIA report for each key environmental aspect are also summarised and presented in this Manual.
1.1.4 The EM&A Manual has been developed as a means to verify the effectiveness and adequacy of the mitigation measures recommended in the EIA such that additional mitigation measures or remedial action, if deemed necessary, can be formulated during the construction of the project. The recommended EM&A Programme is to be carried out by an Environmental Team (ET) formed before the commencement of the works.
1.1.5 Environmental regulations currently enforced in Hong Kong pertaining to air quality, noise, waste management, water quality, and etc. and the recommendations given in the EIA Report have been referenced to in the preparation of this EM&A Manual.
1.2 Objectives of this EM&A Programme
1.2.1 The main objectives of this EM&A programme are:
· To provide a database of baseline environmental quality for subsequent checking during the construction phase of the works;
· To provide information at an early stage for identification of potential problem areas and formulation of additional environmental mitigation measures where necessary should any of the environmental control measures or practices fail to achieve the target standards;
· To verify the environmental impacts predicted in the EIA Study for the project;
· To determine project compliance with relevant regulatory standards, requirements and guidelines;
· To outline remedial measures to be undertaken if unexpected problems or unacceptable impacts arise; and
· To provide data against which environmental audits may be undertaken effectively.
1.3 Content of this EM&A Manual
1.3.1 The recommended EM&A programme in this Manual contains the following information:
· Duties of the various project staff and their respective responsibilities with regards to the EM&A requirements during construction;
· Information on project organisation, work schedule and activities;
· Requirements with respect to the work schedule and the necessary EM&A programme to detect the various possible environmental impacts;
· Definition of Action Limit Levels and the establishment of Event/Action Plans;
· Requirements for reviewing potential sources of pollution and assessing working procedures in the event of non-compliance with the environmental criteria;
· Requirements for the presentation of EM&A data and appropriate reporting procedures; and
· Proposed field data forms to be adopted during the various phases of the works.
1.3.2 An Implementation Schedule (IS) of the environmental mitigation measures has been developed in accordance with the requirements of clause 4.3 of the EIA Study Brief [Appendix 1.1 refers].
1.3.3 This EM&A Manual shall be regarded as an evolving document that should be updated when necessary to reflect the activities on site (e.g. when alternative monitoring locations are proposed). The updated EM&A Manual shall be prepared by the Contractor’s ET and submitted to the Engineer’s Representative (ER) and EPD for agreement.
2 Project Description
2.1 The Subject Site and its Environs
2.1.1 The Project involves the construction of a helipad by mini-bored piling in coastal waters at Kam Lo Hom (North), Yung Shue Wan. No dredging or reclamation works are required for the construction.
2.1.2 The helipad deck will be located approximately 25 metres from the existing formed land, and an access road will be constructed to link the proposed helipad with the existing Emergency Vehicular Access (EVA) [Figure 2.1 refers].
2.1.3
The site location was selected after due consideration of
the operational requirements and environmental impact potential of constructing
and operating the Yung Shue Wan helipad at each of seven site locations [refer
to Sub-section 2.23 of the EIA Report for Helipad
at Yung Shue Wan, Lamma Island].
2.1.4 The majority of the developments along the coast of Yung Shue Wan are residential village houses, varying from single to 3 storeys high. Some of these buildings are used for commercial purpose on the ground floor (e.g., grocery store and restaurant), which are not considered noise sensitive. There are isolated and abandoned village houses located to the north of Kam Lo Hom (currently zoned “Green Belt”). There is line of sight between developments and proposed helipad site/EVA works area.
2.1.5 In addition, the proposed helipad is bound by the Hongkong Electric Co. Ltd.’s Lamma Power Station, which is approximately 800 m due south west to Yung Shue Wan and a refuse transfer station (RTS) immediately adjacent to the proposed site (to the southeast). There are no major road networks within Lamma Island.

4 Air Quality
4.1 Introduction
4.1.1 Based on the air quality impact assessment, it has been identified that no significant impacts will arise from the construction and operation of the helipad through the proper implementation of dust control measures as required under the Air Pollution Control (Construction Dust) Regulation. While no specific control measures have been recommended, general air quality control measures are recommended for implementation as good site practices.
4.1.2 The ET shall check the Contractor’s implementation of air quality control measures during the regular site environmental audit.
4.2 Environmental Audit
4.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.
4.2.2 In order to check that the air quality control measures have been implemented by the Contractor as good site practices, the ET shall include the following items as part of their site inspections:
· Heights from which materials are dropped should be restricted as far as practicable to minimise the fugitive dust arising from unloading/loading.
·
All
spraying of materials and surfaces should avoid excessive water usage;
· Immediately before leaving a construction site, every vehicle shall be washed to remove any dusty materials from its body and wheels.
·
Erection
of hoarding of not less than 2.4 m high from ground level along the site
boundary;
· Vehicles that have the potential to create dust while transporting materials should be covered, with the cover properly secured and extended over the edges of the side and tail boards;
· Travelling speeds should be controlled to reduce traffic induced dust dispersion and re-suspension within the site from the operating haul trucks.
· Where a vehicle leaving a construction site is carrying a load of dusty materials, the load shall be covered entirely by clean impervious sheeting to ensure that the dusty materials do not leak from the vehicle.
· Any stockpile of dusty materials shall be either: (a) covered entirely by impervious sheeting; (b) placed in an area sheltered on the top and the 3 sides; or (c) sprayed with water or a dust suppression chemical so as to maintain the entire surface wet.
· All dusty materials shall be sprayed with water or a dust suppression chemical immediately prior to any loading, unloading or transfer operation so as to maintain the dusty materials wet.
4.2.3 All the dust control measures as recommended in the Air Pollution Control (Construction Dust) Regulation, where applicable, should also be implemented.
5 Noise
5.1 Introduction
5.1.1 During the construction phase of the helipad, power mechanical equipment (PME) used for the helipad construction will be the primary noise sources. The key noise generating activities include:
·
Site
clearance for the erection of site office, hoarding and fencing;
·
Temporary
staging construction and demolition;
· Pile installation; and
· Deck and EVA construction.
5.1.2 Noise sensitive receivers (NSRs) have been identified in accordance with Annex 13 of the EIAO TM. As required under Clause 3.4.2.2 (iii) (b) of the EIA Study Brief, the selection of representative NSRs has been presented to and agreed by the Authority prior to commencement of this noise impact assessment.
5.2 Noise Monitoring Parameters
5.2.1 Monitoring of noise levels at the proposed sensitive receiver locations shall be undertaken by the ET during the baseline and construction phases of the project to ensure that any increase in noise levels as a result of the construction works are readily detected and rectified in a timely fashion.
5.2.2 The construction noise level will be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Noise measurements will be carried out with an integrating sound level meter using the ‘fast’ response mode. Leq(30 min) will be used as the monitoring parameter for the time period between 07:00-19:00 hours on normal weekdays. For all other time periods, Leq(5 min) will be employed for comparison with the Noise Control Ordinance criteria.
5.2.3 As supplementary information for data auditing statistical results such as L10 and L90 will also be obtained for reference.
5.2.4 In addition to carrying out noise monitoring, control and mitigation measures are recommended for implementation by the Contractor. The ET shall check the implementation of these measures during the regular site environmental audits. As described in Section 9 of this Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.
5.3 Monitoring Equipment
5.3.1 As referred to in the Technical Memorandum (TM) issued under the Noise Control Ordinance (NCO), sound level meters in compliance with the International Electrical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications will be used for carrying out the noise monitoring.
5.3.2 Immediately prior to and following each noise measurement the accuracy of the sound level meter will be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level from before and after the noise measurement agrees to within 1.0dB. Calibration equipment to be used should meet IEC 942, Type 1 specifications, and succeeding standard specifications for sound level meters applicable in Hong Kong. Annual calibration of the noise monitoring equipment by an accredited laboratory will be carried out for compliance with IEC publications 651 and 804 and any other relevant standards.
5.3.3 Noise measurements shall not be made if the wind speed exceeds 5ms-1 or if gusts exceed 10ms-1. The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in ms-1. Measurements shall not be made while air temperatures are outside the manufacturer’s specified range or when other intrusive noise sources (other than influencing factors) are apparent at the assessment point.
5.3.4 Sufficient noise measuring equipment and associated instrumentation should be available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation will be clearly labelled, stored and maintained according to the manufacturer’s instructions.
5.4 Monitoring Procedure
5.4.1 Monitoring will be carried out with reference to the following documents:
·
Technical Memorandum on the Assessment of Noise from
Construction Work other than Percussive Piling, Hong Kong Government;
·
Technical Memorandum on the Assessment of Noise
from Construction Works in Designated Areas, Hong Kong Government
·
Technical Memorandum for the Assessment of Noise
from places other than Domestic Premises, Public Places or Construction Sites,
Hong Kong Government;
·
or
succeeding standards and guidelines.
5.4.2 The monitoring stations will normally be at a point 1 m from the exterior of the sensitive receivers building facade and be at a position 1.2 m above the ground. When a measurement is to be made of noise being received at a place other than a building, the assessment point will be at least 1.2 m above ground level, at an appropriate point. The appropriate measurement positions should be at least 3.5 m from any reflecting surface other than the ground and have an unobstructed view of the Site. In such instances where free-field measurements are conducted, a positive correction of 3dB(A) will be applied to the relevant target limits.
5.4.3 The microphone of the sound level meter will be so orientated that it is pointing in the direction of the Site and at the source of noise being monitored such that the microphone is perpendicular to the plane of the incident sound-waves. It will be protected using an appropriate windshield. To avoid reflections from the operator’s body, the microphone will be mounted on a tripod, whether attached to the sound level meter or not. Noise measurements will be rounded to the nearest whole dB, with values of 0.5 dB or more being rounded upwards.
5.4.4 Noise will not be monitored in the presence of mist, fog or rain, when wind is at a steady speed exceeding 5 m/s, or when gusts exceed 10m/s.
5.4.5 For monitoring locations located in the vicinity of the sensitive receivers, care shall be taken to cause minimal disturbance to the occupants during monitoring.
5.4.6 Noise measurements shall be recorded on a field data sheet together with relevant information including project name, date and time of sampling, monitoring location and parameters, site observations and remarks. A sample field data sheet is attached in Appendix 10.1.
5.5 Proposed Monitoring Locations
5.5.1 The noise impact assessment presented in the EIA report indicated that the unmitigated construction noise levels at all NSRs are found to comply with the daytime noise standards stated in Table 1B, Annex 5 of EIAO TM. Noise mitigation measures have been recommended in the EIA report and shall be implemented by the Contractor in accordance with the requirements under the Noise Control Ordinance. The Contractor shall be responsible for the design and implementation of the noise mitigation measures.
5.5.2 Figure 5.1 illustrates the locations of the proposed noise monitoring locations NSR3 and NSR4, as referred in the EIA Report. NSR3 corresponds to the North Lamma Clinic, while NSR4 is a residential village house located about 220 metres southeast of the helipad site,. The status and locations of noise sensitive receivers may change after issuing this Manual. If such case exists, the ET Leader shall propose updated monitoring locations and seek approval from ER and agreement from the IC(E) and EPD of the proposal.
5.5.3 When alternative monitoring locations are proposed, the monitoring locations shall be chosen based on the following criteria:
· At locations close to the major site activities which are likely to have noise impacts;
· Close to the noise sensitive receivers (as defined by the EIAO TM); and
· For monitoring locations located in the vicinity of the sensitive receivers, care shall be taken to cause minimal disturbance to occupants during monitoring.
5.6 Baseline Monitoring
5.6.1 Daily noise monitoring shall be carried out at all designated monitoring locations for a period of at least two weeks prior to the commencement of the Work to establish the baseline noise conditions. The frequency of monitoring for each station will include at least:
· One set of measurements between 07:00-19:00 hours on normal weekdays;
· One set of measurements between 19:00-23:00 hours on normal weekdays;
· One set of measurements between 23:00-07:00 hours of next day; and
· One set of measurements between 07:00-19:00 hours on holidays.
5.7 Impact Monitoring
5.7.1 The ET shall conduct noise monitoring at all designated monitoring stations. Noise monitoring shall be conducted on a weekly basis when noise-generating activities are underway. One set of measurements shall be taken between 07:00-19:00 hours on normal working days.
5.7.2 General construction works carried out during restricted hours are controlled by the Construction Noise Permit System, under the NCO. The Contractor shall apply for a Construction Noise Permit (CNP) and abide by the requirements of the permit should works be necessary in the restricted hours.
5.7.3 In case of non-compliance with the construction noise criteria, more frequent monitoring as specified in the Event/Action Plans [Appendix 5.1 refers] shall be carried out. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.
5.8 Event and Action Plan
5.8.1
The Action Limit levels for
construction noise are defined in Table
5.1Table 5.1Table 5.1Table 5.1. Should non-compliance of the noise criteria
occur, actions in accordance with the Event/Action Plan [Appendix 5.1 refers] shall be carried out.

5.9 Noise Mitigation Measures
5.9.1 While no adverse noise impacts have been identified through the noise impact assessment, the EIA report has nevertheless recommended construction noise control and mitigation measures to be implemented by the Contractor as good site practice.
5.9.2 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.
5.9.3 In order to check that the noise control measures have been implemented by the Contractor as good site practices, the ET shall include the following items as part of their site inspections:
·
Noisy
equipment and noisy activities should be located as far away from the NSRs as
is practical;
·
Use
of silence equipment and installation of temporary and movable noise barriers.
Movable barriers shall be positioned as close as possible to powered mechanical
equipment so that they are not visible to sensitive receivers;
·
Unused
equipment should be turned off;
·
Powered
mechanical equipment should be kept to a minimum and the parallel use of noisy
equipment / machinery should be avoided; and
· Regular maintenance of all plant and equipment.
5.9.4
The
Contractor shall observe and comply with the relevant statutory requirements
and guidelines.
5.9.5 Operational noise monitoring is impracticable as there are no scheduled helicopter flights, and so operational phase noise monitoring is not recommended.
5.9.6 Should the need arise, the local community may lodge noise complaints with the Islands District Office by the following means:
· Fax: 2815 2291
· Email: dois@had.gov.hk
· Address: Islands District Office, Harbour Building, 20th Floor, 38 Pier road, Central.
6 Waste Management
6.1 Introduction
6.1.1 Based on the initial waste generation assessment, it has been identified that minimal volumes of C&D materials (including inert and non-inert materials), chemical waste and general refuse will be generated from the construction activities.
6.1.2 Through proper on-site handling and storage (covered containers), reuse (of inert C&D materials) and off-site disposal (via approved waste collectors to approved waste facilities and/or disposal grounds) the generation, handling and disposal of these wastes will not give rise to any adverse environmental impacts. However, given the potential for environmental impacts to arise from improper waste management (e.g. visual impact, nuisance, etc.), it is recommended that control and mitigation measures be implemented as part of general good site practices.
6.2 Environmental Audit
6.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.
6.2.2 In order to check that the waste control and mitigation measures have been implemented by the Contractor as good site practices, the ET shall include the following items as part of their site inspections and audit:
i)
Spoil generated from the piling activities needs to be
properly handled to minimise contamination to the marine water and any exposed
ground areas due to leakage or improper storage (i.e. onto bare ground instead
of into tanks). Any dredged
sediments generated from the site works shall be handled in accordance with
ETWB TCW No. 34/2002;
v)
With reference to ETWBTC (W) No.31/2004, Trip-ticket System for Disposal of Construction and
Demolition Material, a trip ticket system should be established at the outset of
the construction of the helipad to monitor the disposal of C&D and solid
wastes from the site to public filling facilities and landfills;
vi)
Under the Waste Disposal (Chemical Waste) (General)
Regulation, the Contractor shall register with EPD as a Chemical Waste Producer
if there is any use of chemicals on site including lubricants, paints, diesel
fuel, etc. Only licensed chemical waste
collectors shall be employed to collect any chemical waste generated at site. The handling, storage, transportation and
disposal of chemical wastes shall be conducted in accordance with the Code of Practice on the Packaging, Labelling
and Storage of Chemical Wastes and A
Guide to the Chemical Waste Control Scheme both published by EPD;
vii)
Stockpiling is not envisaged, however if it becomes
unavoidable, stockpiling in any vegetated areas shall be avoided (as far as
possible) and shall be covered with tarpaulin and/or watered to prevent
windblown dust and/or surface runoff;
xi)
A recording system for the amount of wastes generated,
recycled and disposed of (including the disposal sites) shall be proposed by the
contractor, and the ET Leader shall include a summary of such information in
each monthly EM&A Report.
6.2.3
The
Contractor shall also observe and comply with the relevant statutory
requirements and guidelines and their updated versions.
7 Water Quality
7.1 Introduction
7.1.1 Given the scale and nature of the Project, and given that there will be no dredging or reclamation works involved, the initial water quality assessment conducted under the EIA study indicates that minimal disturbances will be generated and thus no unacceptable water quality impacts are foreseen.
7.1.2 Although no significant adverse water quality impacts are predicted and no specific mitigation is necessary, general control and mitigation measures are recommended for implementation by the works Contractor as good site practices.
7.2 Environmental Audit
7.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.
7.2.2 The ET shall include the measures outlined below as part of their site inspections to check that the Contractor has implemented the waste control and mitigation measures as good site practices.
7.2.3
As a precautionary good site practice
measure, it is recommended that a silt curtain be installed along the western side
of the project boundary from the vertical seawall (off which the access road link
is to be developed) to the edge of the helipad footprintaround the working area. The
silt curtain(s) shall reach seabed level.
7.2.4
The following good site practices are
also recommended to further minimise the potential water quality impacts in order to addition to the
procedures outlined under Section 6.5.3 to comply with ProPECC PN 1/94:
· The holding tank should be fitted with a tight fitting seal to prevent sediment leakage; and
· The Contractor should ensure that the excavator grab
seal is tightly closed and the hoist speed is suitably low;
· The holding tank should not be filled to a level which will cause
overflow of sediment during loading and transportation; and
· Large objects should be removed from the excavator
grab to avoid sediment spills.
7.2.5
The
Contractor shall also observe and comply with the relevant statutory
requirements and guidelines.
8 Ecology
8.1 Introduction
8.1.1 Based on the initial ecological impact assessment of the EIA report, it was identified that the project will not result in any significant sub-tidal habitat loss and there is not anticipated to be any impact on the hard coral community from pile installation so long as good working practices are followed.
8.1.2 While no specific mitigation measures are considered necessary, the control and mitigation measures recommended for water quality are relevant to the mitigation against ecological impacts and as such should be implemented by the Contractor as part of their day-to-day good site practice. The ET should check the implementation of these measures during the regular site environmental audit.
8.2 Environmental Audit
8.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.
8.2.2
The
ET shall include the measures outlined in Section
7.2.4 and Section 8.2.48.2.4 as part of their site inspections to check that
the Contractor has implemented the waste control and mitigation measures as
good site practices. These measures
shall apply to the control of both water quality and sub-tidal and inter-tidal
life around the helipad site.
8.2.3
As a precautionary good site practice
measure, it is recommended that a silt curtain be installed along the western side of
the project boundary from the vertical seawall (off which the access road link
is to be developed) to the edge of the helipad footprint. The silt curtain(s)
shall reach seabed levelaround the working area.
8.2.4 In addition to the good site practices recommended to further minimise the potential water quality impacts [refer to Section 7.2.4] the following measures are also recommended to be implemented to reduce impacts on the sub-tidal ecology:
· Particular care should be taken when demolishing the existing concrete planter to ensure no waste enters the water column;
· Particular care should be taken when decommissioning the silt curtain to avoid sudden dispersion of muddy water which may cause adverse impact to the nearby marine life; and
· Materials storage areas should be located well away from the seawall, and any such areas should be covered during the works.
8.2.5 The measures outlined in the relevant statutory requirements and guidelines should also be observed and complied with.
9 Site Environmental Audit
9.1 Site Surveillance
9.1.1 Site surveillance provides a direct means to trigger and enforce the specified environmental protection and pollution control measures are in compliance with the contract specifications. They shall be undertaken regularly and routinely by ET to inspect the activities at the works site in order to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented by the Contractor in accordance with the EM&A recommendations. With well-defined pollution control and mitigation specifications and a well-established site inspection, deficiency and action reporting system, the site inspection is one of the most effective tools to enforce the environmental protection requirements on the site.
9.1.2 The ET Leader is responsible for formulation of the environmental site inspection, deficiency and action reporting system, and for carrying out the site inspections under the EM&A works. He shall prepare and submit a proposal on the site inspection, deficiency and action reporting procedures within 21 days of the construction contract commencement to the Contractor for agreement and to the ER and IC(E) for approval. A preliminary site inspection, deficiency and action reporting system in the form of a flowchart has been prepared for reference, and is presented in Figure 9.1 for review and refinement by the ET at the commencement of the Project.
9.1.3 The ET shall conduct a site inspection at least once per week during helipad construction. The areas of inspection shall include, but are not be limited to, the environmental situation, and pollution control and mitigation measures within the site. It should also review the environmental situation outside the site area that is likely to be affected, directly or indirectly, by the site activities. The ET Leader shall make reference to the following information in conducting the inspection:
1. The EIA recommendations on environmental protection and pollution control mitigation measures with regard to air quality, noise, waste management, water quality, and ecological impacts;
2. On-going results of the EM&A programme;
3. Works progress and programme;
4. Individual works methodology proposals (which shall include proposals on associated pollution control measures);

The documents shall at least include the updated Work Progress Reports, the updated Works Programme, application letters for different license/permits under the environmental protection laws, and all valid licence(s)/permit(s). The site diary shall also be available for the ET’s inspection upon his request.
9.2.4 After reviewing the document, the ET shall advise the ER and the Contractor of any non-compliance with the contractual and legislative requirements on environmental protection and pollution control for them to take follow-up actions. If the ET’s review concludes that the current status on licence/permit application and any environmental protection and pollution control preparation works may not cope with the works programme or may result in potential violation of environmental protection and pollution control requirements by the works in due course, he shall also advise the Contractor and the ER accordingly. The review shall be copied to IC(E) for any follow-up action.
9.2.5 Upon receipt of the advice, the Contractor shall undertake immediate action to remedy the situation. The ER shall check that the Contractor has taken appropriate action in order that the environmental protection and pollution control requirements are fulfilled.
9.3 Environmental Complaints
9.3.1 Complaints reviewed on environmental issues shall be referred to the ET Leader for carrying out complaint investigation procedures. Upon receipt of complaints the ET shall undertake the tasks outlined in points 1-9 below. The complaint investigation procedures are also presented in form of a flow chart in Figure 9.2 for easy reference.
1. Log complaint and date of receipt onto the complaint database and inform the IC(E) immediately;
2. Investigate the complaint to determine its validity, and to assess whether the source of the problem is due to works activities;
3. If a complaint is valid and due to works, identify mitigation measures in consultations with the IC(E);
4. If mitigation measures are required, advise the Contractor accordingly;
5. Review the Contractor’s implementation of the identified mitigation measures, and the concurrent situation;
6. If the complaint is transferred from EPD, submit interim report to EPD on status of the complaint investigation an follow-up action within the time frame assigned by EPD;
