Diversion measures: In order to divert the C&D waste from the construction site, the

measures below will be taken HoaBinh and Citenco are in charge to inspect thesemeasures are carried out onsite Some of these measures include, but are not limited to:

 Diverting salvageable materials from disposal where feasible, and storing them in

a dry and clean area

 Labeling all recycling containers clearly and in the most appropriate languages,and locating them in close proximity to the building under construction phase

 Hazardous waste will be managed by a licensed hazardous waste vendor

Waste Prevention: In order to prevent the generation of new waste onsite during

construction, HoaBinh requests that each major vendor cooperate in planning forminimal or take-back packaging, and just-in-time delivery

Transportation: Citenco will collect construction waste very day via truck Waste will be

transported out of the Site to Binh Chanh landfill and recycle center

Documentation: HoaBinh will hire Mr Le Hoang Son (representative of Citenco), who

is authorized from Government to collect, segregate and treat the construction waste.The detail waste management process of this company will be shown in “HOABINH -PROCESS OF WASTE MANAGEMENT.pdf”

Contamination Prevention Measures

The best practice measures for keeping materials destined for recycle and reuse free ofcontaminants and wet waste include:

 A designated location on site will be served for this purpose In term of HoaBinh’responsibility, all waste materials will be sorted separately by followingcategories: waste materials (concrete, steel and plastic), hazardous wastematerials, and store them at designated location on site

 All waste containers are watertight and covered securely to prevent rain waterpollution

Communication and Education Measures

The regular communications about CWM practices throughout the construction processinclude:

 HoaBinh sets up the waste management plan at the beginning of constructionstage

 Work with Mr Le Hoang Son (Transported Teams Waste) for the waste collectingprocess / waste management process and the compliant procedures

 Waste prevention, recycling training and recycling activities will be discussed ateach site safety meeting with all key employees

 All sub-contractor will be notified of this plan and will be expected to comply withthe plan

 All sub-contractor will receive a copy of this plan and clearly specify this wastemanagement plan as a mandatory requirement

 Providing a list of acceptable / unacceptable materials for recycling or reuse andposting it on site

 Assign one or two staffs to record and manage the quantities of waste

*END OF PLAN*

Step 2: Monitor and record all construction waste generated onsite, list quantities ofeach type that were diverted and landfill, and the total percentage of waste diverted fromlandfill disposal Below is the waste record that HoaBinh tracked until August 2015 Thespreadsheet show more than 85.34% waste is diverted from the land fill which makes acontribution to get 2 points for LEED and qualify DGNB - PRO2.1 Environmantal Impact

Step 3: Make CWMP progress report

WASTE MANAGEMENT PROGRESS REPORT

Recycled Content Points

The recycled content value of a material assembly is determined by weight Therecycled fraction of the assembly is then multiplied by the cost of assembly to determinethe recycled content value

Mechanical, electrical and plumbing components, and specialty items such aselevators cannot be included in this calculation Include only materials permanentlyinstalled in the project

Which:

- Post-consumer recycled content is the percentage of material in a product that was

consumer waste The recycled material was generated by household, commercial,industrial, or institutional end-users and can no longer be used for its intendedpurpose It includes returns of materials from the distribution chain, examplesinclude construction and demolition debris, materials collected through recyclingprograms, discarded products (e.g., furniture, cabinetry, decking), and landscapingwaste (e.g., leaves, grass clippings, tree trimmings)

- Pre-consumer recycled content is the percentage of material in a product that is

recycled from manufacturing waste Examples include planer shavings, sawdust,bagasse, walnut shells, culls, trimmed materials, over issue publications, andobsolete inventories Excluding rework, regrind or scrap materials capable of beingreclaimed within the same process that generated them
