Environmental protection and sustainable development are part and parcel of the daily operations of the Gammon Construction Limited (referred to hereinafter as the GCL). GCL will initiate appropriate actions in order to minimize, and where possible eliminate, the environmental impact arising from the construction of this project.
Gammon Construction Limited (GCL) has been awarded of the Contract No. HY/2017/10 – Tuen Mun Chek Lap Kok Link – Northern Connection Tunnel Buildings, Electrical and Mechanical Works for the Highways Department (HyD) of the Government of the Hong Kong Special Administrative Region (HKSARG). The Works comprise the construction of Tunnel buildings, Ancillary Buildings and facilities, tunnel cladding and signage as well as E&M works including the Tunnel Ventilation System, tunnel and approach road lighting system, Toll Collection System, Plumbing and Drainage System in tunnel and approach road, Fire Services Systems in tunnel and approach road.
The Waste Management Plan (WMP) has been prepared to describe the arrangements for minimising the generation of construction and demolition (C&D) materials and disposing of the surplus C&D materials during the course of the Works.
This contract-specific WMP shall be deposited to the Director of Environmental Protection in accordance with the Condition 2.10 of the Environmental Permit No. EP-354/2009/D.
The WMP shall address the potential and actual impacts and necessary mitigation measures in light of the preferred construction programme and consists of the following:-
· A review of the ordinances, regulations, codes of practices as well as contractual obligations that are applicable to the wastes arising from the Works;
· An organisation chart setting out the roles and responsibilities of the GCL’s personnel responsible for waste management and appropriate mitigation measures;
· An analysis of timing, quantities and types of C&D materials are anticipated to be generated in the course of the execution of the Works;
· A classification of C&D materials into inert portion (Public Fill) and non-inert portion (C&D Waste);
· Proposals for avoiding/minimizing, handling, recycling, reuse, return, storage and disposal of C&D materials, chemical waste and general refuse;
· An appraisal of the potential establishment on-site of a sorting facility, including the identification of potential area on-site to facilitate the waste sorting;
· A proposal for maintaining the site in a clean and tidy condition;
· A monitoring and auditing proposal to ensure that the requirements of the WMP are properly implemented.
The principles of waste management adopted in this project shall be in line with Gammon's environmental management system which follows the requirements of the ISO 14001 and based on a cyclical process comprising policy, planning, implementation & operation, checking and corrective action and management review. A policy statement is given in Appendix A. Core elements of waste management are listed in Table 3.1 below and described in the following sections of the WMP:

The various waste management options shall be categorised in terms of preference from an environmental viewpoint. The options considered to be more preferable have the least impacts and are more sustainable in the longer term. Hence, the hierarchy of waste management is as follows:
· Avoidance and minimisation, i.e. not generating waste through changing or improving practices and design;
· Reuse of materials, thus avoiding disposal;
· Recovery and recycling, thus avoiding disposal; and
· Treatment and disposal, according to relevant laws, guidelines and good practice.
This hierarchy shall be used to evaluate waste management options, thus allowing maximum waste reduction. Waste reduction measures shall be introduced at the detailed planning stage and carried through the construction activities, whenever possible, by careful purchasing control, reuse of formworks and good site management. By reducing or eliminating over-ordering of construction materials, waste is avoided and costs are reduced both in terms of purchasing of raw materials and in disposing of wastes.

The waste generated from the construction activities shall be divided into distinct categories based on their composition, as follows:
(a) Construction and demolition (C&D) materials
(i) Inert C&D materials
(ii) Non-inert C&D materials
(b) Chemical wastes
(c) General refuses
The estimated quantities, types of the C&D materials and corresponding disposal grounds will be updated monthly and indicated in the monthly programme for disposal of C&D materials, which will be reported to the Engineer via submissions of monthly waste flow tables as shown in Appendix D. All anticipated disposal scenarios and transportation modes are summarized in Appendix E.
C&D materials comprise unwanted materials generated during construction, including rejected structures and materials, materials which have been over ordered or are surplus to requirements, and materials used and discarded.
C&D material could be divided into two categories according to whether they are inert or non-inert. Inert C&D material are known as rock, rubble, boulder, earth, soil, sand, concrete, asphalt, brick, tile, masonry and used bentonite, where to be maximized the reuse of these materials within the Contract and to be disposed of the surplus of these materials to other Contracts, subjected to the approval or direction of the Engineer’s Representative. Under any circumstances that no site is able to receive the unsuitable C&D materials for the filling purpose, GCL will apply to CEDD for the public fill reception facilities (PFRF) as a back-up option.
Non-inert C&D material are such as metal, timber, vegetation, packaging waste, organic material and all recyclables and non-recyclables is called “C&D Waste”. C&D waste, excluding recyclables, shall be disposed of at WENT Landfill.
Recyclables are mainly metals, paper/cardboard packaging and plastics. Plastics refer to plastic bottles/containers, plastic sheets/foam from packaging material. Recyclables would be collected by relevant recyclers. Non-recyclable materials are treated as general refuse.
The following general low waste construction designs and principles together with careful planning shall be adopted to avoid/minimise C&D material generation. Such measures include: -
(a) Management of construction materials such that over-ordering, poor storage and maintenance, mishandling as well as improper operation procedures shall be avoided.
(b) Restriction on use of hardwood such that softwood, metal props and/or proprietary steel system shall be considered for false work and the shoring of trenches and pits;
(c) The formwork shall be designed to maximise the use of standard wooden panels so that high reuse levels can be achieved. More durable alternatives such as steel formwork or plastic facing shall be considered for repetitive areas to increase the potential for reuse.
(d) C&D materials shall be, as much as possible and practicable, separated into reusable items and materials to be disposed of or recycled. It shall be conducted at the immediate working area to avoid loss/leakage and cross contamination during handling.
(e) All C&D materials arising from or in connection with the construction and demolition work shall be sorted on-site and be separated into different categories for disposal at landfills, public filling areas, or reuse and recycling as appropriate. The sorting area may be revised from time to time in order to suit the construction activities.
(f) Useful materials such as timber, rubble and steel/metal shall be segregated for reuse. For example formwork and timber shall be cleaned for reuse, off-cuts of reinforcement shall be sorted into usable lengths and short off cuts stacked for scrap metal. Where it is no longer reusable, scrap steel and metal items will be collected by recycling companies.
(g) Segregated materials shall be temporarily stored at designated areas for reuse on site. Steel will be stored at the reinforcement yards, timber at the formwork yard and rubble in a stockpile (either covered or sprayed to control dust). Cardboard and paper packaging recovered from site shall be properly stockpiled in dry condition and covered.
(h) In order to avoid over-order of concrete, accurate calculation shall be made prior to concrete pouring. Close supervision shall also be arranged during concrete pouring to avoid over-cast.
(i) Surplus concrete shall be used for paving of temporary road or cast of concrete blocks for bunding etc. as far as practicable. In case immediate use of surplus concrete cannot be identified, the surplus concrete will be temporarily poured into designated surplus concrete pouring areas on site for further disposal to public filling areas.
(j) Entirely cover every stock of more than 20 bags of cement by impervious sheeting and carry out the de-bagging, batching and mixing processes in an area sheltered on the top and the 3 sides. Damp and gather the waste cement bags for proper disposal.
(k) Used bentonite shall only be disposed of at Public Fill area.
GCL designate suitable areas onsite for the storage, sorting and segregation of construction waste. The areas that are designated by GCL will be clearly defined with appropriate signage and barriers (or similar) and allow for easy access by workers and vehicles. As the project progresses it is anticipated that the designated areas will be reviewed depending upon construction program requirements. The areas designated by GCL will be sufficient for the amounts of construction waste that are anticipated to be generated during the course of the contract. The sorting mechanism is shown in Table 8.1. The sorting for inert C&D Materials shall be carried out immediately at the relevant operation area and would dispose to TM38 or TKO137 Fill Bank accordingly or other alternative disposal ground as agreed by the Engineer’s Representative. The locations for the temporary storage of C&D waste, such as general refuses and chemical waste are shown in Appendix F.

Chemical wastes are the substances defined by the Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation. Chemical wastes generated from the construction sites will primarily arise from the maintenance of plant and equipment. These may typically include oils, lubricants, paints and solvents. The tentative locations for temporary storage of chemical waste are shown in Appendix F. Containers used for the storage of chemical waste shall:
· be suitable for the substance they are holding, resistant to corrosion, maintained in a good condition, and securely closed;
· have a capacity of less than 450 litres unless the specification have been approved by the EPD; and
· display a label in English and Chinese in accordance with instruction prescribed in Schedule 2 of the Waste Disposal (Chemical Waste)(General) Regulation.
The storage area for chemical wastes shall:
· be clearly labelled and used solely for the storage of chemical waste;
· be enclosed on at least three sides;
· have an impermeable floor and bunding, of capacity to accommodate 110% of the volume of the largest container or 20% by volume of the chemical waste stored in that area;
· have adequate ventilation;
· be covered to prevent rainfall entering (water collected within the bund must be tested and disposed as chemical waste if necessary); and
· be arranged so that incompatible materials are adequately separated.
Disposal of chemical waste shall:
· be via a licensed waste collector;
· be to an off-site facility licensed to receive chemical waste, such as a recycling facility located in Yuen Long Industrial Estate or the Chemical Waste Treatment Facility located in Tsing Yi.
General refuses include food wastes, non-recyclable materials (including waste paper/cardboard packaging, plastics and timber) and other debris arising from various construction activities, site workforce and site housekeeping. Number and location of placement of rubbish bins with the arrangement for on-site sorting of aluminum cans, plastic bottles and papers shall be specified and submitted to ER for approval. The collection and disposal of general refuses insides the skips shall be not less than once in every three days. General refuses shall be disposed of at WENT Landfill.
Measures that encourage waste avoidance/minimization include:
· Reducing the number of photo copies to a minimum and by copying on both sides of paper for internal documents and external documents where appropriate;
· Preventing over-ordering of office equipment and consumables;
· Procuring green office equipment and consumables in terms of energy efficiency, recycled content and durability, etc.;
· Providing drinking facility and encouraging employees to bring their own cup; and
· Discouraging take-out food.
Additional measures that facilitate reuse/recycling and orderly disposal include:
· Deploying sufficient recycle bins at convenient locations to facilitate collection of recyclables including wasted aluminium cans, plastic bottles and cardboard and papers packaging;
· Deploying sufficient refuse collection bin at convenient locations to facilitate collection of non-recyclables for disposal at landfills; and
· Participating local collection scheme (e.g. scheme launched by District Board) if available.
The use of timber in Temporary Works construction will be avoided, reduce or minimised as far as possible. A method statement will be submitted to the Engineer for agreement prior to commencement of the relevant Temporary Works if the timber to be used for a Temporary Works construction process/activity exceeds 5m3. The method statement will include the justification for and the measures taken to minimise the use of timber in the said Temporary Works.
Instead of traditional formwork, more durable formwork system will be adopted for column, slab and wall construction for ancillary buildings to facilitate reuse onsite and minimize waste.
Sustainable timber procurement policy is setup by the Corporate to material procurement and all subcontractors, to procure timber and timber products only from independently certified legal and sustainable sources, such as the Forest Stewardship Council (FSC) Scheme.
The formworks will be designed to maximise the use of standard wooden panels so that high reuse levels can be achieved. More durable alternatives such as reusable metal formwork, falsework, trench supports and the like shall be optimized for use in repetitive areas to increase the potential for reuse, if applicable.
A summary table containing the description, justification and the estimated quantity for every work process / activity requiring the use of timber for Temporary Works construction irrespective of the quantity of timber used is prepared Appendix G.
In accordance with DEVB TC(W) No. 6/2010, with tender invitation was on or after 1 November 2010, the administration of CHIT/ DDF was streamlined. CHIT in lieu of the bar-coded Disposal Delivery Form (DDF) should be used at all prescribed facilities, i.e. public fill reception facilities, sorting facilities, outlying island transfer facilities and landfills. Moreover, under the Construction Waste Disposal Charging Scheme, GCL registered with EPD a disposal account and will adopt the CHIT as the enhanced control of C&D material disposal. The control procedure on off-site disposal of C&D materials is shown in Appendix H. The sample of CHIT, purpose-designed trip-tickets are presented in Appendix I.
Every C&D material disposal trip to the public fill reception facilities and designated landfill shall be controlled under the trip-ticket system as per the DEVB TC(W) No. 6/2010 in order to avoid fly-tipping. Appendix G gives the site procedure for the TTS operation.
For disposal of chemical wastes, the trip-ticket system as per the Waste Disposal (Chemical Waste) Regulation in which licensed collector will be employed and the chemical wastes will be disposed of at designated chemical waste treatment facility.
GCL will inform all truck drivers engaged for removal of C&D materials from the Site of the following particular points:
· Each truck carrying C&D materials leaving the Site for a disposal ground must bear a duly completed CHIT, irrespective of the location and nature of the disposal ground; and
· The C&D materials must be disposed of at the disposal grounds stipulated in the Contract or directed by the Engineer or alternative disposal grounds approved by the Engineer.
GCL would formulate a guiding protocol for truck drivers being engaged and give all of them a copy for their information. Where necessary, a tool box talk relating to the protocol will be given to all engaged driver. The protocol is shown in Appendix J.
GCL shall arrange weekly inspection attended by the Environmental Officer and the Engineer to inspect the site to ensure satisfactory performance on compliance with the WMP with due regards to the followings:
(a) Inert C&D materials suitable for recycling into aggregates are recovered and delivered to Tuen Mun Area 38 or other designated recycling facilities as notified by the Engineer or the Public Fill Committee (Port Works Division of CED);
(b) A disposal recording system is operating satisfactorily for recording C&D materials removed from the Site;
(c) On-site sorting of C&D materials is properly carried out to recover inert C&D materials and reusable and/or recyclable materials before disposal;
(d) Paper/cardboard packaging, and metals including aluminium cans are recovered and collected; and
(e) Plastic bottles/containers or plastic sheets/foam from packaging are collected as far as possible for recycling.
GCL may arrange the weekly inspection on waste management performance to be carried out along with the weekly safety walks for safety or other site inspections.
GCL shall prepare and agree with the Engineer a comprehensive checklist for use during weekly inspections on waste management. The defects or deficiencies identified during the weekly inspection on waste management together with their respective locations and the corresponding due dates for rectification as set by the Engineer nominated site representative should be entered in a summary table of follow-up actions similar to the one established for weekly safety walks for monitoring of the rectification progress. GCL may need to prepare more than one comprehensive checklist to suit the variety of works at various portions of the Site. It is recommended that items covered in the checklist should primarily address:-
(a) the physical conditions of the Site (e.g. housekeeping, site tidiness and cleanliness, etc.);
(b) the adequacy of measures applied to each category of waste; and
(c) the availability/accessibility/maintenance of waste management facilities.
Immediately after the weekly inspection, the summary table of follow-up actions shall be agreed and signed by both the assigned person and the Engineer and a copy should be kept by the Engineer for monitoring of the progress of rectification and for payment. GCL shall take prompt action to rectify the deficiencies identified and shall report the status of action taken before the forthcoming weekly inspection.
Should deficiency with regard to waste management affairs persists, the Event Contingency Plan as detailed below shall be triggered. Non-compliance shall include the following situations:
· Infringement of legal requirements with respect to waste issues.
· Persistent outstanding of control measures stated in the WMP as identified during the site inspection or audit.

To ensure the effectiveness of the Trip-Ticket System, the following item will be discussed at every Site Safety and Environmental Management Committee meeting, and Site Safety and Environmental Committee meeting or ad-hoc meetings on as-needed basis:
1. Review the site management plan and implementation of the TTS, and identify areas for improvement;
2. Audit the quantity of C&D materials removed from the Site (based on the DRS and survey records) against the quantities of C&D materials delivered to the disposal ground designated in the Contract (e.g. based on EPD website) and directed or approved by the Supervising Officer;
3. Review incidents of non-compliance and discuss the necessary follow-up actions for TTS; and
4. Monitor the follow-up action on defects and deficiencies identified.
The Environmental Officer and other site personnel (if they have not attended similar course before) shall be arranged to attend training on waste management organised by training institutes or organisations as considered appropriate.
The Environmental Officer shall arrange and provide training on waste management in the site-specific induction and its refresher training for all persons employed by the GCL or his subcontractor on the Works or in connection with the Contract. The training should cover the waste management policy, targets, measures for on-site sorting of C&D materials and measurement on waste management performance on the Site. According to ER requirement, induction training shall be carried out within first 2 days of the employment and refreshment training shall be carried out by every 6 months.
The Environmental Officer is allowed to develop and provide toolbox talks for the topic on on-site sorting of C&D materials to promote the workers' awareness on handling, sorting, reuse and recycling of C&D materials. Training material for environmental toolbox talks with regard to waste management shall be prepared by the Environmental Officer and disseminated to supervisor/foremen and subcontractor’s representatives for conducting tool-box talks to all workers or labourers at regular intervals.
The Section 8.1.2 of the EM&A Manual gives recommendations on mitigation measures of waste management, which are:
· The waste management hierarchy (Appendix B) should be strictly followed. This hierarchy should be adopted to evaluate the waste management options in order to maximise the extent of waste reduction and cost reduction. The records of quantities of waste generated, recycled and disposed (locations) should be properly documented.
· A trip-ticket system should be established in accordance with DEVB TC(W) No. 6/2010 and Waste Disposal (Charges for Disposal of Construction Waste) Regulation to monitor the disposal of public fill and solid wastes at public filling facilities and landfills, and to control fly-tipping. A trip-ticket system would be included as one of the contractual requirements for the Contractor to strictly implement. The Engineer would also regularly audit the effectiveness of the system.
· A recording system for the amount of waste generated, recycled and disposed (locations) should be established. The future Contractor should also provide proper training to workers regarding the appropriate concepts of site cleanliness and waste management procedures, e.g. waste reduction, reuse and recycling all the time.
· The CEDD should be timely notified of the estimated spoil volumes to be generated and the Public Fill Committee should be notified and agreement sort on the disposal of surplus inert C&D materials e.g. good quality rock during detailed design of the TM-CLKL project. Wherever practicable, C&D materials should be segregated from other wastes to avoid contamination and to ensure acceptability at public filling areas or reclamation sites.
· The extent of cutting operation should be optimised where possible. Earth retaining structures and bored pile walls should be proposed to minimise the extent of cutting.
· The surplus surcharge should be transferred to a fill bank.
· The site and surroundings shall be kept tidy and litter free.
· No waste shall be burnt on site.
· Make provisions in contract documents to allow and promote the use of recycled aggregates where appropriate.
· Prohibit the Contractor to dispose of C&D materials at any sensitive locations e.g. natural habitat, etc. The Contractor should propose the final disposal sites in the EMP and WMP for approval before implementation.
· Stockpiled material shall be covered by tarpaulin and /or watered as appropriate to prevent windblown dust and surface run off.
· Excavated material in trucks shall be covered by tarpaulins to reduce the potential for spillage and dust generation.
· Wheel washing facilities shall be used by all trucks leaving the site to prevent transfer of mud onto public roads.
· Standard formwork or pre-fabrication should be used as far as practicable so as to minimise the C&D materials arising. The use of more durable formwork or plastic facing for construction works should also be considered. The use of wooden hoardings should be avoided and metal hoarding should be used to facilitate recycling. Purchasing of construction materials should be carefully planned in order to avoid over-ordering and wastage.
· The Contractor should recycle as many C&D waste as possible on-site. The public fill and C&D waste should be segregated and stored in separate containers or skips to facilitate the reuse or recycling of materials and proper disposal. Where practicable, the concrete and masonry should be crushed and used as fill materials. Steel reinforcement bar should be collected for use by scrap steel mills. Different areas of the sites should be considered for segregation and storage activities.
· All falsework will be steel instead of wood, as far as possible.
· Chemical waste producers should register with the EPD. Chemical waste should be handled in accordance with the Code of Practice on the Packaging, Handling and Storage of Chemical Wastes as follows:
- Suitable for the substance to be held, resistant to corrosion, maintained in good conditions and securely closed;
- Having a capacity of <450L unless the specifications have been approved by the EPD; and
- Displaying a label in English and Chinese according to the instructions prescribed in Schedule 2 of the Regulations.
- Clearly labelled and used solely for the storage of chemical wastes;
- Enclosed with at least 3 sides;
- Impermeable floor and bund with capacity to accommodate 110% of the volume of the largest container or 20% by volume of the chemical waste stored in the area, whichever is greatest;
- Adequate ventilation;
- Sufficiently covered to prevent rainfall entering (water collected within the bund must be tested and disposed of as chemical waste, if necessary); and
- Incompatible materials are adequately separated.
· Waste oils, chemicals or solvents shall not be disposed of to drain;
· Adequate numbers of portable toilets should be provided for on-site workers. Portable toilets should be maintained in reasonable states, which will not deter the workers from utilising them. Night soil should be regularly collected by licensed collectors.
· General refuse arising on-site should be stored in enclosed bins or compaction units separately from C&D and chemical wastes. Sufficient dustbins shall be provided for storage of waste as required under the Public Cleansing and Prevention of Nuisances By-laws. In addition, general refuse shall be cleared not less than once in every three days and shall be disposed of to the nearest licensed landfill or refuse transfer station. Burning of refuse on construction sites is prohibited.
· All waste containers shall be in a secure area on hard standing. Aluminium cans are usually collected and recovered from the waste stream by individual collectors if they are segregated and easily accessible. Separately labelled bins for their deposition should be provided as far as practicable.
· Office wastes can be reduced by recycling of paper if such volume is sufficiently large to warrant collection. Participation in a local collection scheme by the Contractor should be advocated. Waste separation facilities for paper, aluminium cans, plastic bottles, etc. should be provided on-site.
· Training shall be provided to workers about the concepts of site cleanliness and appropriate waste management procedure, including waste reduction, reuse and recycling.
