1 BACKGROUND
Waste to municipal landfill is a pressing and critical issue in Hong Kong and construction waste is a sensitive topic that raises much attention. About 25% of the waste to Hong Kong landfills is construction waste. In simple terms, the generation and management of waste for Gammon impacts profitability, productivity and is an added logistical burden; it is also associated with housekeeping and safety.
Gammons quantity (tonnes) of landfill waste has increased from 26,000 tonnes in 2007 to 35,800 tonnes in 2012 (+37.7%) and the majority of waste disposed of in municipal landfill representing 2.5% of Hong Kong total.

2 PURPOSE OF THE HANDBOOK
With the baseline of 2007, building division aimed to achieve 30% reduction* in landfill intensity by end 2018, we must: 1) exercise better planning and design 2) reduce the waste generated and 3) reduce sent to landfill by increasing reuse and recycle arrangements. There are sub-reduction targets in 2014 (by 10%) and 2016 (by 20%) for achieving our ultimate target step by step. * Rebar or steel waste is not counted in the target figure

4 WASTE MANAGEMENT STRATEGIES
4.1 Hierarchy
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:
Planning and Design
Recycling & Reprocessing material
Avoidance and Minimization
Zero conservation of recourses
Reuse of materials
Planning and Design
Recycling & Reprocessing material
Avoidance and Minimization
Zero conservation of recourses
Reuse of materials
This hierarchy shall be used to evaluate waste management options, thus allowing maximum waste reduction. Rethink is careful planning at the design and drawing stages. It is at this stage that the greatest reductions in waste can be achieved. Reduce waste by 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 waste. On site, the Reuse and Recycle of materials should be maximized to avoid Disposal.
4.2 Waste Management
The proposed strategy is not limited to collection & disposal system. Instead, it proposes to employ a multi-pronged approach that revolves round the waste hierarchy participatory principle. Procurement strategy Manage at source - Proposing a task force team Education Incentives to subcontractors

5.5 Task Force for Waste Management
Depending on the size of individual project, task force led by a project coordinator/supervisor provided with direct labours and technically supported by the project environmental team shall implement waste management on site (planning, waste identification of each construction stage, sorting and separation at source, housekeeping, waste collection, disposal management and reporting).
6 ANALYSIS OF WASTE GENERATION AT DIFFERENT STAGE
To give a brief idea on the amount of waste generated in different stages, the landfill waste of various building projects were shown in Appendix B. The scope of projects, contract sum and landfill waste intensity are stated for easy comparison.
Different types of waste will be generated throughout the construction period of the Project from various construction activities and daily operation of the construction site. The major construction activities and the associated waste generation are identified in Appendix C.

7 MANAGEMENT OF LANDFILL WASTE ON SITE
All Construction and Demolition (C&D) materials arising from or in connection with the Works will be sorted on site to recover reusable and/or recyclable materials. All sorted and processed surplus materials arising from or in connection with the Works from the Site will be promptly removed to minimise temporary stockpiling on the Site.
A system will be devised for on-site sorting of C&D materials. The system will include the identification of the source of generation, estimated quantity, arrangement for on-site sorting and/or collection, temporary storage areas, frequency of collection by recycling contractors or frequency of removal off the Site, etc. Each project should prepare their project specific Waste Management Plan and a template was attached in Appendix D.
7.1 Prediction of construction activities and Estimation of waste generation
Identify the materials likely to be discarded and at what stage of the project. This should be carried out prior to the commencement of the site works. This involves looking at the construction program and the project design and identifying materials in-flows and outflows. Estimate the quantities by using normal ordering margins and packaging mode. Moreover, using landfill waste intensity target of building home to calculate the total waste generation of project. These will give the information to team for scheduling bin numbers, sizes and likely changeovers
7.2 Set waste diversion target
Setting waste diversion target can be based on green building guidelines, BEAM Plus and LEED. These guidelines do not only focus on recycling, instead they focus on the diverting waste from landfills by finding multiple alternatives for end uses of the waste, namely reuse on site, recycling, donation for reuse on another site. All of these diversion methods count towards credit compliance 75% construction waste diverted for two points. For BEAM Plus, two credit is for 60% of construction waste recycled.

7.3 Identify & select recycler according to actual market availability
Contact recyclers using this handbook, Appendix E, or EPD Recycling Directories. https://www.wastereduction.gov.hk/en/quickaccess/vicinity.htm#1 To deal with recyclers, there are several points to pay attention.
The condition of recyclable materials Any drop boxes and pick-up service available Options of collection: call for service, scheduled pick-up, or send to their
collection points The charge of services including drop box rental and transport fee Provide receipts for types and quantities of materials collected
7.4 Planning of mode of logistic, transportation and sorting facilities
Better planning of hardware support would encourage on-site sorting. Since it is difficult to separate the waste materials after they mixed, project team should make sorting convenient by placing recycling bins, designated areas close to the work on each floor or designated area near the refuse chute. Centralize sorting area with different recycling bins are recommended to facilitate the final collection for different types of waste.
To plan the logistic routine for the waste collection from different floor, refuse chute, jump lift and hoist are preferred. Landfill waste, recyclables and inert waste should be transported down separately to avoid contamination; thus, one more refuse chute in site is recommended to facilitate waste collection as well as vertical transportation. Operation team better to have different arrangement on using vertical logistic to balance the demand of material delivery and waste collection. The location of rubbish skip and collection points should be closed to site entrance for easy removed by collectors.
7.5 Planning of manpower by subletting, task force etc
Implement processes to ensure the separation of chosen wastes by subcontractors and task force. Ensure that everyone is aware of their obligations and responsibilities. Subcontractors have to sort their waste before disposal of designated areas that reduces the burden of task force. Consider back-charging a subcontractor who doesnt separate their waste. Conduct training about the materials to be separated and getting any ideas from staff.
7.6 Regular review on the efficiency of overall sorting, collection and disposal
Once construction has started, keep the receipts from recycling and garbage disposal for planning estimates in future waste management budget. Regular meeting with staff to get feedback on how sorting can best be done onsite. Consider review the management when the construction stage change.

8 WASTE REDUCTION MEASURES
Measures and Descriptions Rethink Reduce Reuse Recycle Design and Planning Stage
Project designs for waste prevention and minimization - adopting construction design and method which prevent and provide
less waste
Lean Construction - adopting designs using thinner internal walls and floor slabs and
reducing foundation size which could minimize the amount of raw materials being used and thus reduce the amount of waste
Modular Building Designs and Pre-casting of Construction Components - pre-casting of construction components and install them on-site
BIM application - The use of BIM 3D CAD Models for design co-ordination of the
architectural, structural, E&M components to reduce the wastage from abortive work
Better Scheduling of Construction Tasks by Stage - carrying out of one task at a time by scheduling tasks by stage to
prevent contamination and mixing of waste
Better Site Planning and Logistic Planning - allocating waste facilities at the right places and making sure the logistic
is convenient for implementing on-site waste management
Construction Waste Management and Reduction Plan - planning for waste handling, sorting, collection and disposal, allocating
spaces for placing waste facilities and for waste management, appointing staffs for managing and monitoring and etc before the construction

Measures and Descriptions Rethink Reduce Reuse Recycle
Construction Stage
Prevent waste with efficient purchasing - avoiding over-estimation and ordering too many materials which could
not be fully utilized in the construction - purchase materials with minimal packaging, while ensuring goods are
not damaged during delivery - coordinate materials delivery to coincide with its use to reduce material
damage and waste
Make Good Use of Internal Materials Exchange System - the marketplace allow both buyers and sellers to exchange information
and post message online for excessive or 2nd hand items located in their sites and offices and ready for transfer internally.
-
Building Better Coordination and Cooperation among Stakeholders in the Supply Chain - developing linkages and coordinating with other stakeholders in the
supply to transport unwanted construction materials to other places where these materials could be utilized. For examples, materials suppliers could take back surplus materials and packing materials from contractors; unwanted inert materials could be transported to concrete plant and/or used in other concurrent projects; contractors could coordinate with recyclers to pick up recyclables; and etc.
The Use of Reusable Metals for Formwork - replacing wooden panels which could only be used once with metals
which could be reused for many times for formwork
Provision of Waste Management and Facilities - providing accessible waste collection and sorting facilities on site
On-Site Sorting - avoiding mixing of construction materials and conduct sorting on-site as
early as once the waste are produced when the construction labours are doing their tasks

Creating Incentives to Reduce Waste - waste charging is a common example of financial incentive by
internalizing costs of waste management to the producers; other non-financial incentives include voluntary schemes, creating co-benefits for practicing waste reduction measures and award schemes; and etc
For the detailed measures, please refer to Appendix F.

9 MONITORING AND REVIEWING
9.1 Internal site Inspection
The execution team shall arrange regular inspection to inspect the site to ensure satisfactory performance on compliance with the waste management plan with due regards to the followings:
i. inert C&D materials suitable for recycling into aggregates are recovered and delivered to designated recycling facilities as notified by the Architect or the Public Fill Committee (Port Works Division of CED);
ii. if the Contract involves demolition works, appropriate sequential demolition has been employed to facilitate recovering as much as possible reusable and recyclable materials;
iii. a disposal recording system is operating satisfactorily for recording C&D materials removed from the Site; and
iv. 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.
Team may arrange the regular inspection on waste management performance to be carried out along with the regular internal safety & environmental walks.
9.2 Record Keeping and Reporting
Environmental Engineer shall keep adequate and proper records such as delivery dockets and measurement records relating to the implementation of the waste management plan. All waste treatment should be properly recorded by receipt, photo, delivery form and summary, supporting document should also be provided for individual waste.
Smart Waste Account was introduced to all projects for tracing back the quantities of waste to public fill, landfill and designated areas. Data analysis charts are also provided for project team to review. Environmental Performance Data (EPD) will be used to record all waste removed off site each month. The estimated and actual quantities of wastes that will be generated each month from the project will be reported in a monthly basis.
9.3 Waste Audit
The waste reduction should be assessed in two ways:
Project-wise Targeting the waste management on site and seeking out or developing
ways to divert waste from disposal
To review the site management, the project-based waste baseline audit should be conducted. By identifying the measures of waste reduction, the facilities support on site and etc, the scoring of baseline audit would reflect the implementation of waste management. A waste baseline audit scorecard was developed to quantify site waste management efforts, shown as Appendix G. A kick-off example and waste management audit schedule are provided in Appendix H. The good practices and difficulties can also be discussed in the audit meeting and presented in the revised version of the waste management handbook.

Building Home The overall waste reduction would be reviewed regularly. The waste data of
building projects would be used to calculate the landfill waste intensity (tonnes of landfill waste per HK$ 1million turnover). The Interim Review will be carried in mid-2013, end-2013, 2015 and 2017.
A mix of both approaches should be considered using the waste reduction hierarchy to set priorities.
10 TRAINING AND PROMOTION
The environmental engineer shall arrange and provide training on waste management in the site-specific induction and its refresher training for all persons employed by the Contractor or his sub-contractor 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.
The environmental engineer 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 engineer and disseminated to supervisor/foremen and subcontractor's representatives for conducting tool-box talks to all workers or labourers at regular intervals.
To motivate subcontractors participation, Waste Management Key Performance Index (WMKPI) should be introduced to rank subcontractors on performance indicators tracked across implementation of waste management, Appendix I. Set some standards and common vision so that subcontractors have more understanding of our objectives and follow easily. Project team and Operation team would help in the assessment by reporting subcontractors performance to environmental engineer. The index and rating can be different from each project according its statues. Best subcontractor of the month in waste management could be awarded to praise their effort.

1. Background
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.
(Project description)
2. Purpose of the Plan
With the baseline of 2007 (4.13 tons per HKD 1M turnover), building division aimed to achieve 30% reduction in landfill intensity by the end of 2018 (2.89 tons per HKD 1M turnover), we must: 1. exercise better planning and design; 2. reduce the waste generated and; 3. reduce sent to landfill by increasing reuse and recycle arrangements
Set the target for this project is to diverting construction and demolition debris from disposal in landfills and incinerators; redirecting recyclable resources back to the manufacturing process or redirecting reusable materials to appropriate sites. (Please refer to waste management handbook, section 7.2.)
This Project-Specific Waste Management Plan (WMP) aims to describe the arrangements for minimising the generation of surplus construction and demolition (C&D) materials and carrying out effective on-site sorting of C&D materials and minimising the generation of C&D waste from equipment/material packaging during the course of the Works. 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 Contractors
personnel responsible for waste management and appropriate mitigation measures;
An analysis of timing, quantities and types of Construction and Demolition (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);

An appraisal of the potential establishment on site of a sorting facility, including the identification of potential area on-site of facilitate the waste sorting;
A monitoring and auditing proposal to ensure that the requirements of the WMP are properly implemented.
3. Waste Management Strategies
3.1 Hierarchy
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: Rethink is careful planning at the design and drawing stages. It is at this stage
that the greatest reductions in waste can be achieved.; Reduce waste by 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 waste.;
On site, the Reuse and Recycle of materials should be maximized to avoid 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.
4. Organization Structure
The project organisation with respect to waste management works is outlined in the following sections.
4.1 Project Manager
The Project Manager is responsible to the Contract Manager for overall planning, site operations, appointment of committee members for waste management, staff supervision control co-ordination and external liaison. He is ultimately responsible for all aspects of waste management issues within the Project, which they achieve by implementation of the WMH.

6. Waste Reduction Measures
6.1 Reduce Waste at Source
This section is the measures taken in Design and Planning Stage and Procurement that is more focusing on Rethink and Reduce. Waste Management Handbook, Section 8 & Appendix E)
For example, 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.
Precast unit or pre-fabricated unit is also encouraged to adopt since it will reduce the wastage from the waste generation on site. BIM application is also an effective tool to avoid the wastage due to crushing of E&M services.
6.2 Management of Construction and Demolition Materials
All Construction and Demolition (C&D) materials arising from or in connection with the Works will be sorted on the Site to recover reusable and/or recyclable materials. The system will include the identification of waste, estimated quantity, arrangement for on-site sorting and/or collection, temporary storage areas, etc. The temporary on site sorting facilities layout plan for sorting facilities is provided and reviewed regularly, Figure 1.
Description of the planning of logistic mode, sorting facilities
Materials should be sorted at source but not limited to the following categories: Hard Rock and Large Broken Concrete suitable for Reuse on the Site or recycling
at a designated location;
Residue Concrete
Metals;
Paper and plastics;
Timber waste;
Chemical waste; and
Materials suitable for Disposal at Public Fill Reception Facilities and Landfills/Outlying Islands Transfer Facilities.
The planning of logistic routine for the waste collection from different floor should be considered, refuse chute, jump lift and hoist. Landfill waste, recyclables and inert waste should be transported down separately to avoid contamination.

Waste facilities to facilitate on-site sorting, collection and temporary storage of waste materials is continued to maintain. The waste facilities including the following:
1. Designated area for temporary storage of Inert C&D Material 2. Designated waste skip for temporary storage of non-inert C&D Material 3. Recycling cages for collection of waste metal, plastic and paper. 4. Recycling bins for collection of waste papers, cans and plastic bottles 5. Designated storage area for chemical waste
Sufficient space for temporary storage of C&D materials will be identified and provided to facilitate collection and/or sorting on the Site. Except for those inert C&D materials to be reused on the Site, all other C&D materials off the Site will be removed as soon as practicable to optimise the use of the on-site storage space.
As presented in the Waste Management Hierarchy, the GCL accords the highest priority to managing waste through reduction at source. To this end, the following measures shall be implemented.
Management of construction materials such that over-ordering, poor storage and maintenance, mishandling as well as improper operation procedures shall be avoided;
Restriction on use of hardwood such that softwood, metal props and/or proprietary steel system shall be considered for falsework and the shoring of trenches and pits;
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;
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;
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;
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;
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;
The remaining non-reusable C&D materials shall be sorted on-site into the inert portion (e.g. rock, brick, bituminous material, concrete and soil, etc.) as the public fill and the non-inert portion (e.g. timber, vegetation and paper, etc.) as the C&D waste. All inert C&D materials shall be broken down according to the

Project Page No. 7
Dumping License conditions prior to disposal to government approved public filling outlets. The hard inert construction and demolition (C&D) materials, such as broken rock and concrete which can be recycled into aggregates for reuse in construction works, shall be delivered to the C&D material sorting and recycling facility at Chai Wan Barging Point. The non-recyclable portion of C&D waste (containing no more than 30% by weight of inert content) shall be tipped at the landfill such as SENT Landfill. Recycling companies will be arranged to collect the recyclable portion of C&D waste;
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; and
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.
Materials suppliers could take back surplus materials and packing materials.
(Please inert appropriate measures adopted on site)
6.3 Cut and Fill Balance of Inert Waste
In order to maximize the reuse of surplus inert construction waste generated from the site, team will strike for reusing excavated material as back fill material to balance cut and fill on site. If cut and fill could not be balanced on site, team will try their best endeavour to identify the alternative disposal site (i.e. other construction project) in order to reuse surplus inert C&D material.
6.4 Recycling
To minimise the amount of waste disposal to landfills, the general refuse shall be reused and recycled as much as practical. Waste sorting and segregation shall be carried out in accordance with the following categories for recycling:
Steel Bars
Plastic (i.e. plastic bag, plastic bottle, plastic packaging, etc.) Rubber;
Paper;
Wood/ timber; and
Metal (i.e. aluminium can, steel metal, ferrous metal, and non-ferrous metal).
Equipment and material packaging (ie paper and cardboard) will be recovered, properly stockpiled in dry and covered condition to prevent cross contamination by other C&D materials. Particular attention will be paid to avoid cross contamination in the course of collecting paper for recycling. Arrangements will be made with recycling contractors to ensure that recyclable materials sorted from the Site are collected with reasonable care.

Regular Meeting with the Subcontractor to discuss the implementation status of WMP;
Training related to waste management of the project will be provided to the operation team to increase their awareness;
Closely monitor the recycling rate to ensure successful outcome of achieving recycling rate.
7.2 Record Keeping and Reporting
All waste treatment (i.e. recycle, reuse etc) should be properly recorded by receipt, photo, delivery form and summary, supporting document should also be provided for individual waste.
Smart Waste Account was introduced to all projects for tracing back the quantities of waste to public fill, landfill and designated areas. Data analysis charts are also provided for project team to review. Environmental Performance Data (EPD) will be used to record all waste removed off site each month. The estimated and actual quantities of wastes that will be generated each month from the project will be reported in a monthly basis.
7.3 Waste Audit
To review the site management, the project-based waste baseline audit will be conducted quarterly. Project shall be audited by a committee though site visit. A waste baseline audit scorecard was developed to quantify site waste management efforts, shown as Appendix A. By identifying the measures of waste reduction, the facilities support on site and etc, the scoring of baseline audit would reflect the implementation of waste management.
8. Training and Incentive
The Environmental engineer shall be arranged to attend training on waste management organised by training institutes or organisations as considered appropriate.
The EE shall arrange and provide training on waste management in the site-specific induction and its refresher training for all persons. 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.
The EE 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

Date: Time: Venue:

Present: Mr. Vincent YUEN Mr. Percy CHAN Mr. Sherman TANG Mr. Jason FUNG Ms. Selina CHIN
(VY) (PC) (ST) (JF) (SC)
Item Description Action 1 Data analysis The landfill waste data of Seymour Rd project and Shiu Fai Terrace was
analyzed. The forthcoming activities were discussed to predict the types and amount of waste generation.
Note
2 Difficulties of waste management/reduction at High-rise residential development sitting on congested site
ST and JF expressed that they have several difficulties to tackle with in waste management.
- limited space on site access level for waste collection and cart away - no buffer area to be provided for temporary waste storage - only one refuse chute cannot cater for vertical transportation of
sorted/separated waste. Proper time schedule has to be sought for waste management
- since each residential unit on each floor is not sizable enough to allow for proper waste sorting and segregation
- only small quantities of inert waste/other waste generated each day which cannot fully load one dump truck for disposal
3 Developing Centralized Collection Project managers stated that they have to store inert waste / recyclables
for long time in site as the quantities is low. Developing a centralized collection was suggested. A dump truck was hired by Building Home to collect inert waste / recyclables from different projects.
PC
There is a concern about the trip ticket issue since it would involve different projects.
Post-meeting note: After clarified with EPD, centralized collection is only possible for those project with contract sum below $1M (small scale - fitting out), for those project / construction site with large than $1M, it is necessary to apply their own billing account with using their own chit ticket and can not be shared with other project and it is all required under Waste Disposal (charges for Disposal of construction Waste) Regulation.
4 Details of Recycling Companies Managers suggested that details of recycling companies should be stated
in Waste Management Handbook - type and condition of waste they accept - any pick-up service provided - service charging
