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 these measures 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 for minimal

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 of contaminants 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 following categories: waste materials (concrete, steel and plastic), hazardous waste materials, and store them at designated location on site

− All waste containers are watertight and covered securely to prevent rain water pollution

Communication and Education Measures

The regular communications about CWM practices throughout the construction process include:

− HoaBinh sets up the waste management plan at the beginning of construction stage

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

− Waste prevention, recycling training and recycling activities will be discussed at each site safety meeting with all key employees

− All sub-contractor will be notified of this plan and will be expected to comply with the plan

− All sub-contractor will receive a copy of this plan and clearly specify this waste management plan as a mandatory requirement

− Providing a list of acceptable / unacceptable materials for recycling or reuse and posting 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 of each type that were diverted and landfill, and the total percentage of waste diverted from landfill disposal Below is the waste record that HoaBinh tracked until August 2015 The spreadsheet show more than 85.34% waste is diverted from the land fill which makes a contribution to get 2 points for LEED and qualify DGNB - PRO2.1 Environmantal Impact

7.2 Practice

Step 1: Contractor Prepares Indoor Environmental Quality Management Plan as below

INDOOR ENVIRONMENTAL QUALITY MANAGEMENT PLAN

Minimize pollution affect to HVAC system

− The most significant potential IAQ sources from construction are dust, moisture, and VOC’s If there are any construction works that generate dust, such as drywall sanding, concrete cutting, masonry work, wood sawing and insulating or pollution levels occur, the Contractor will coordinate with MEP Contractor to isolate the area where is installing the HVAC system, cover the HVAC equipment storing at the Site, seal off the return air system openings completely for the duration of the task

− The Contractor cooperates with the MEP Contractor to supply the suitable ventilation system in the construction process (depending on the spaces with humidity, dryness fraction, high density smell and other pollution activities) to ensure the indoor air quality as well as safe health for the workers

− The mechanical rooms are not used to store construction or waste materials Rooms should be kept clean and neat This activity is the responsibility of the all Subcontractors and monitored by Main Contractor, for conformance to the IAQ plan

− Documentation that the above guidelines are followed during the construction phase of the project, pictures will be taken daily by the Mechanical Contractor and
